The following sections describe the features that are associated with license keys. The VLANs associated with the ports connecting an ESRP-aware switch to an ESRP-enabled switch must be configured using an 802.

Security Licensing for Features Under License Control

NOTE The command unconfig switch all does not clear licensing information. Once it is enabled on the switch, this license cannot be disabled.

Verifying the Advanced Edge License
To verify the Advanced Edge license, use the show switch command.

Obtaining an Advanced Edge License
You can order the desired functionality from the factory, using the appropriate model of the desired product. If you order licensing from the factory, the switch arrives packaged with a certificate that contains the unique license key(s), and instructions for enabling the correct functionality on the switch. The certificate is typically packaged with the switch documentation. Once the license key is entered, it should not be necessary to enter the information again. However, we recommend keeping the certificate for your records. You can upgrade the Advanced Edge licensing of an existing product by purchasing a voucher for the desired product and functionality. Please contact your supplier to purchase a voucher. The voucher contains information and instructions on obtaining a license key for the switch using the Extreme Networks Support website at: http://esupport.extremenetworks.com or by phoning Extreme Networks Technical Support at: • (800) 998-2408 • (408) 579-2826

Security Licensing for Features Under License Control
Certain additional ExtremeWare security features, such as the use of Secure Shell (SSH2) encryption, might be under United States export restriction control. Extreme Networks ships these security features in a disabled state. In order to enable the use of these features, you must first obtain an export license, which you can do through Extreme Networks (at no extra charge).

SSH2 Encryption
ExtremeWare version 6.0 and above supports the SSH2 protocol. SSH2 allows the encryption of Telnet session data. The encryption methods used are under U.S. export restriction control. To obtain information on enabling SSH2 encryption, access the Extreme Networks Support website at: http://esupport.extremenetworks.com Fill out a contact form to indicate compliance or noncompliance with the export restrictions. If you are in compliance, you will be given information that will allow you to enable security features.

Accessing the Switch

This chapter describes the following topics: • Understanding the Command Syntax on page 41 • Line-Editing Keys on page 43 • Command History on page 44 • Common Commands on page 44 • Configuring Management Access on page 46 • Domain Name Service Client Services on page 49 • Checking Basic Connectivity on page 50

Understanding the Command Syntax
This section describes the steps to take when entering a command. Refer to the sections that follow for detailed information on using the command-line interface. When entering a command at the prompt, ensure that you have the appropriate privilege level. Most configuration commands require you to have the administrator privilege level. To use the command-line interface (CLI), follow these steps: 1 Enter the command name. If the command does not include a parameter or values, skip to step 3. If the command requires more information, continue to step 2. 2 If the command includes a parameter, enter the parameter name and values. 3 The value part of the command specifies how you want the parameter to be set. Values include numerics, strings, or addresses, depending on the parameter. 4 After entering the complete command, press [Return]. NOTE If an asterisk (*) appears in front of the command-line prompt, it indicates that you have outstanding configuration changes that have not been saved. For more information on saving configuration changes, see Appendix D, “Software Upgrade and Boot Options”.

Accessing the Switch

Syntax Helper
The CLI has a built-in syntax helper. If you are unsure of the complete syntax for a particular command, enter as much of the command as possible and press [Return]. The syntax helper provides a list of options for the remainder of the command. The syntax helper also provides assistance if you have entered an incorrect command.

Command Completion with Syntax Helper
ExtremeWare provides command completion by way of the [Tab] key. If you enter a partial command, pressing the [Tab] key posts a list of available options, and places the cursor at the end of the command.

Abbreviated Syntax
Abbreviated syntax is the most unambiguous, shortest allowable abbreviation of a command or parameter. Typically, this is the first three letters of the command. In command tables throughout this guide, abbreviated syntax is noted using bold characters.

NOTE When using abbreviated syntax, you must enter enough characters to make the command unambiguous and distinguishable to the switch.

Command Shortcuts
All named components of the switch configuration must have a unique name. Components are named using the create command. When you enter a command to configure a named component, you do not need to use the keyword of the component. For example, to create a VLAN, you must enter a unique VLAN name:
create vlan engineering

Once you have created the VLAN with a unique name, you can then eliminate the keyword vlan from all other commands that require the name to be entered. For example, on the stand-alone switch, instead of entering the command
config vlan engineering delete port 1-3,6

you could enter the following shortcut:
config engineering delete port 1-3,6

Summit 200 Series Switch Numerical Ranges
Commands that require you to enter one or more port numbers on a Summit 200 series switch use the parameter <portlist> in the syntax. A portlist can be a range of numbers, for example:
port 1-3

You can add additional port numbers to the list, separated by a comma:
port 1-3,6,8

Line-Editing Keys

Names
All named components of the switch configuration must have a unique name. Names must begin with an alphabetical character and are delimited by whitespace, unless enclosed in quotation marks.

Symbols
You may see a variety of symbols shown as part of the command syntax. These symbols explain how to enter the command, and you do not type them as part of the command itself. Table 12 summarizes command syntax symbols. Table 12: Command Syntax Symbols
Symbol Description

< > (angle brackets) Enclose a variable or value. You must specify the variable or value. For example, in the syntax config vlan <name> ipaddress <ip_address> you must supply a VLAN name for <name> and an address for <ip_address> when entering the command. Do not type the angle brackets. [ ] (square brackets) Enclose a required value or list of required arguments. One or more values or arguments can be specified. For example, in the syntax use image [primary | secondary] you must specify either the primary or secondary image when entering the command. Do not type the square brackets. | (vertical bar) Separates mutually exclusive items in a list, one of which must be entered. For example, in the syntax config snmp community [read-only | read-write] <string> you must specify either the read or write community string in the command. Do not type the vertical bar. { } (braces) Enclose an optional value or a list of optional arguments. One or more values or arguments can be specified. For example, in the syntax reboot {<date> <time> | cancel} you can specify either a particular date and time combination, or the keyword cancel to cancel a previously scheduled reboot. If you do not specify an argument, the command will prompt, asking if you want to reboot the switch now. Do not type the braces.

Line-Editing Keys
Table 13 describes the line-editing keys available using the CLI. Table 13: Line-Editing Keys

Accessing the Switch 52 Summit 200 Series Switch Installation and User Guide .

you can manage the switch using the following methods: • Access the CLI by connecting a terminal (or workstation with terminal-emulation software) to the console port. — SSH2 using the CLI interface. Remote access includes: — Telnet using the CLI interface.5 Managing the Switch This chapter describes the following topics: • Overview on page 53 • Using the Console Interface on page 54 • Using Telnet on page 54 • Using Secure Shell 2 (SSH2) on page 57 • Using SNMP on page 58 • Authenticating Users on page 60 • Using Network Login on page 66 • Using EAPOL Flooding on page 71 • Using the Simple Network Time Protocol on page 72 Overview Using ExtremeWare. The switch supports up to the following number of concurrent user sessions: • One console session • Eight Telnet sessions • Eight SSH2 sessions Summit 200 Series Switch Installation and User Guide 53 . — SNMP access using ExtremeWare Enterprise Manager or another SNMP manager. • Access the switch remotely using TCP/IP through one of the switch ports.

Before you can start a Telnet session. Telnet is enabled by default. the switch terminates the session within two hours. the Telnet session defaults to port 23. Check the user manual supplied with the Telnet facility if you are unsure of how to do this. Only VT100 emulation is supported. RS-232 port labeled console.Managing the Switch Using the Console Interface The CLI built into the switch is accessible by way of the 9-pin. you must first configure the switch IP parameters. Once the connection is established. you must configure the switch IP parameters. the Telnet connection will time out after 20 minutes of inactivity. See “Configuring Switch IP Parameters” on page 54 for more information. you must specify the IP address of the device that you want to manage. To open the Telnet session. If idletimeouts are enabled. Using Telnet Any workstation with a Telnet facility should be able to communicate with the switch over a TCP/IP network. Up to eight active Telnet sessions can access the switch concurrently. Connecting to Another Host Using Telnet You can Telnet from the current CLI session to another host using the following command: telnet [<ipaddress> | <hostname>] {<port_number>} If the TCP port number is not specified. Configuring Switch IP Parameters To manage the switch by way of a Telnet connection or by using an SNMP Network Manager. you will see the switch prompt and you may log in. you must add the following information to the BOOTP server: • Switch Media Access Control (MAC) address. You can then start managing the switch without further configuration. Once the connection is established. If a connection to a Telnet session is lost inadvertently. found on the rear label of the switch • IP address • Subnet address mask (optional) Once this is done. the IP address and subnet mask for the switch will be downloaded automatically. 54 Summit 200 Series Switch Installation and User Guide . Using a BOOTP Server If you are using IP and you have a Bootstrap Protocol (BOOTP) server set up correctly on your network. located on the front of the Summit 200 series switch. you will see the switch prompt and you can log in.

NOTE For more information on DHCP/BOOTP relay. The default user names have no passwords assigned. enter them at the login prompt. enter your user name and password. Ensure that you have entered a user name and password with administrator privileges. the switch IP address is not retained through a power cycle. “Virtual LANs (VLANs)”. To use Telnet or an SNMP Network Manager. IP addresses are always assigned to a VLAN. All VLANs within a switch that are configured to use BOOTP to get their IP address use the same MAC address. Telnet. The switch can be assigned multiple IP addresses. To retain the IP address through a power cycle. if you are using BOOTP relay through a router. Therefore. To configure the IP settings manually. To assign IP parameters to the switch. The switch comes configured with a default VLAN named default. NOTE For information on creating and configuring VLANs. — If you have been assigned a user name and password with administrator privileges. you must enter the IP parameters for the switch in order for the SNMP Network Manager. and it must be assigned an IP address and subnet mask. use the default user name admin to log in with administrator privileges. BOOTP is enabled on the default VLAN. 3 At the login prompt. even if the configuration has been saved. see Chapter 15. see Chapter 7. you must perform the following tasks: • Log in to the switch with administrator privileges. “IP Unicast Routing”. For example: login: admin Administrator capabilities enable you to access all switch functions. Manually Configuring the IP Settings If you are using IP without a BOOTP server. follow these steps: 1 Connect a terminal or workstation running terminal-emulation software to the console port. Summit 200 Series Switch Installation and User Guide 55 . you must configure the IP address of the VLAN using the command-line interface. you must have at least one VLAN on the switch. If you configure the switch to use BOOTP. Note that they are both case-sensitive. the BOOTP server must be capable of differentiating its relay based on the gateway portion of the BOOTP packet. 2 At your terminal. or Web interface. Telnet software. — If you are logging in for the first time. or Web interface to communicate with the device. • Assign an IP address and subnet mask to a VLAN.Using Telnet You can enable BOOTP on a per-VLAN basis by using the following command: enable bootp vlan [<name> | all] By default. press [Return] one or more times until you see the login prompt.

To terminate a Telnet session. If this happens. log out of the switch by typing: logout or quit Disconnecting a Telnet Session An administrator-level account can disconnect a Telnet management session.255. or by using classless inter-domain routing notation (CIDR). Using CIDR notation.45.Managing the Switch 4 At the password prompt.67. 2 Determine the session number of the session you want to terminate by using the following command: show session 3 Terminate the session by using the following command: clear session <session_number> 56 Summit 200 Series Switch Installation and User Guide . 5 Assign an IP address and subnetwork mask for the default VLAN by using the following command: config vlan <name> ipaddress <ipaddress> {<subnet_mask>} For example: config vlan default ipaddress 123.8 / 24 6 Configure the default route for the switch using the following command: config iproute add default <gateway> {<metric>} For example: config iproute add default 123.255. by typing: save 8 When you are finished using the facility.45. when configuring any IP addresses for the switch. CIDR uses a forward slash plus the number of bits in the subnet mask.8 255.1 7 Save your configuration changes so that they will be in effect after the next switch reboot.67.45. follow these steps: 1 Log in to the switch with administrator privileges. NOTE As a general rule.67. the user logged in by way of the Telnet connection is notified that the session has been terminated. the command-line prompt displays the name of the switch in its prompt. enter the password and press [Return]. you can express a subnet mask by using dotted decimal notation.0 Your changes take effect immediately. When you have successfully logged in to the switch. the command identical to the one above would be: config vlan default ipaddress 123.

When a user attempts to login using Telnet. You can define a primary and secondary RADIUS server for the switch to contact. RFC 2138) is a mechanism for authenticating and centrally administrating access to network nodes. The RADIUS server implementation automatically negotiates the per-command authentication capability with the switch. and then to the secondary RADIUS server. Per-command authentication allows you to define several levels of user capabilities by controlling the permitted command sets based on the RADIUS username and password. 60 Summit 200 Series Switch Installation and User Guide . the request is relayed to the primary RADIUS server. if the primary does not respond. http. You do not need to configure any additional switch parameters to take advantage of this capability.

When autopolarity is disabled on one or more Ethernet ports. flow control is disabled. It is enabled or disabled as part of autonegotiation. Even though a Gigabit Ethernet port runs only at full duplex. Turning Off Autonegotiation for a Gigabit Ethernet Port In certain interoperability situations. you must specify the duplex setting. you might opt to turn autopolarity off on one or more 10BASE-T and 100BASE-TX ports. The following example turns autopolarity off for ports 3-5 on a Summit 200 series switch: config ports 3-5 auto-polarity off NOTE If you attempt to invoke this command on a Gigabit Ethernet switch port. the link will come up only when a crossover cable is connected to the port. use the following command: config ports <portlist> auto off {speed [10 | 100 | 1000]} duplex [half | full] To configure the system to autonegotiate. you may need to turn autonegotiation off on a Gigabit Ethernet port. When autonegotiation is turned on. the system causes the Ethernet link to come up regardless of the cable type connected to the port. You can also verify the current autopolarity status by using the command: show ports {<portlist>} info detail 78 Summit 200 Series Switch Installation and User Guide . the system displays a message indicating that the specified port is not supported by this feature. the 10/100 Mbps ports autonegotiate the duplex setting.

Load-Sharing on a Summit 200 Series Switch The following example defines a load-sharing group that contains ports 9 through 12. logical port 9 represents physical ports 9 through 12. Verifying the Load-Sharing Configuration The screen output resulting from the show ports configuration command lists the ports that are involved in load sharing and the master logical port identity. For example. a partner switch does not receive a valid indication that the port is not in a forwarding state. NOTE Do not disable a port that is part of a load-sharing group. The traffic filter is defined by the physical port. When using load sharing. To define a load-sharing group. Switch Port-Mirroring Port-mirroring configures the switch to copy all traffic associated with one or more ports. VLANs configured to use other ports in the load-sharing group will have those ports deleted from the VLAN when load sharing becomes enabled. The system uses a traffic filter that copies a group of traffic to the monitor port. The monitor port can be connected to a network analyzer or RMON probe for packet analysis. To enable or disable a load-sharing group. all ports on the switch must be 100 Mbps ports.Configuring Ports on a Switch The following rules apply to the Summit 200 series switch: • Ports on the switch must be of the same port type.

Overview of Virtual LANs The term “VLAN” is used to refer to a collection of devices that communicate as if they were on the same physical LAN. Any set of ports (including all ports on the switch) is considered a VLAN. Benefits Implementing VLANs on your networks has the following advantages: • VLANs help to control traffic—With traditional networks. • VLANs provide extra security—Devices within each VLAN can only communicate with member devices in the same VLAN. If users move to a different subnetwork. the traffic must cross a routing device. congestion can be caused by broadcast traffic that is directed to all network devices. VLANs increase the efficiency of your network because each VLAN can be set up to contain only those devices that must communicate with each other. regardless of whether they require it. the addresses of each endstation must be updated manually. If a device in VLAN Marketing must communicate with devices in VLAN Sales. The segments are defined by flexible user groups you create with the command-line interface. LAN segments are not restricted by the hardware that physically connects them. Summit 200 Series Switch Installation and User Guide 85 . network administrators spend much of their time dealing with moves and changes.

Figure 10: Example of a port-based VLAN on the Summit 200-24 switch Marketing Finance Sales LC24004 For the members of the different IP VLANs to communicate. you must do two things: 1 Assign the port on each switch to the VLAN. For example. 2 Cable the two switches together using one port on each switch per VLAN. and port 26 on the Summit 200-24 switch also belong to VLAN Sales. Figure 11 illustrates a single VLAN that spans a BlackDiamond switch and a Summit 200-24 switch. port 4 on system 1 (the BlackDiamond switch). All ports on the BlackDiamond switch belong to VLAN Sales. and ports 17 through 24 are part of VLAN Marketing. A port can be a member of only one port-based VLAN. 86 Summit 200 Series Switch Installation and User Guide . ports 9 through 16. The Summit 200 series switch supports L2 port-based VLANs. This means that each VLAN must be configured as a router interface with a unique IP address. on the Summit 200-24 switch in Figure 10. the traffic must be routed by the switch. a VLAN name is given to a group of one or more ports on the switch. The two switches are connected using slot 8.Virtual LANs (VLANs) Types of VLANs VLANs can be created according to the following criteria: • Physical port • 802. Ports 1 through 24. Spanning Switches with Port-Based VLANs To create a port-based VLAN that spans two switches. and port 26 on system 2 (the Summit 200-24 switch).

A single port can be a member of only one port-based VLAN. by the port configuration for that VLAN. and may also lead to connectivity problems if non-802.1Q VLAN tag. the server must have a Network Interface Card (NIC) that supports 802.1Q tagging. This may affect packet error counters in other devices. Uses of Tagged VLANs Tagging is most commonly used to create VLANs that span switches. port 6. port 25.518 bytes. multiple VLANs can span two switches with a single trunk. The switch-to-switch connections are typically called trunks. The Summit 200 series switch supports L2 tagged VLANs.3/Ethernet maximum of 1. Not all ports in the VLAN must be tagged. port 6. Tagged VLANs Tagging is a process that inserts a marker (called a tag) into the Ethernet frame.1Q VLAN tag (VLANid) of 1 assigned.1Q tagging. in a daisy-chained fashion. Using tags. The device must have a NIC that supports 802. NOTE The use of 802. As ports are added to a VLAN with an 802. In addition to configuring the VLAN tag for the port. Using this configuration.

All additional VLAN membership for the port must be accompanied by tags. port 26 and system 2. and system 2.1Q tagged packets may lead to the appearance of packets slightly bigger than the current IEEE 802. each VLAN requires its own pair of trunk ports. The default mode of the switch is to have all ports assigned to the VLAN named default with an 802. The switch adds and strips tags. multiple VLANs can span multiple switches using one or more trunks. as shown in Figure 12. Each dedicated port must be connected to a port that is a member of its VLAN on the next switch. As traffic from a port is forwarded out of the switch. slot 8. Another benefit of tagged VLANs is the ability to have a port be a member of multiple VLANs. VLAN Engineering spans system 1 and system 2 by way of a connection between system 1. as required. This is particularly useful if you have a device (such as a server) that must belong to multiple VLANs. Using tags. NOTE Packets arriving tagged with a VLANid that is not configured on a port will be discarded. you decide whether each port will use tagging for that VLAN.

VLAN names are locally significant. a port can simultaneously be a member of one port-based VLAN and multiple tag-based VLANs. A given port can be a member of multiple VLANs. NOTE For the purposes of VLAN classification. • It contains all the ports on a new or initialized switch. with the stipulation that only one of its VLANs uses untagged traffic. Traffic coming from and going to the trunk ports is tagged. It has an internal VLANid of 1. Mixing Port-Based and Tagged VLANs You can configure the switch using a combination of port-based and tagged VLANs. Default VLAN The switch ships with one default VLAN that has the following properties: • The VLAN name is default. or other special character. 90 Summit 200 Series Switch Installation and User Guide . NOTE You should use VLAN names consistently across your entire network. the switch determines if the destination port requires the frames to be tagged or untagged.1Q tag containing a VLANid of zero are treated as untagged. In other words. the VLAN names have no significance to the other switch. VLAN Names Each VLAN is given a name that can be up to 32 characters. VLAN names used on one switch are only meaningful to that switch. The traffic that comes from and goes to the other stations on this network is not tagged. packets arriving on a port with an 802. • The default VLAN is untagged on all ports. • All other stations use untagged traffic. VLAN names can use standard alphanumeric characters. or that contains a space. That is. The following characters are not permitted in a VLAN name: • Space • Comma • Quotation mark VLAN names must begin with an alphabetical letter. Quotation marks can be used to enclose a VLAN name that does not begin with an alphabetical character. All traffic coming from and going to the server is tagged. If another switch is connected to it.

For example. consider the following guidelines: • A port can only accept connections from an endstation/host and should not be connected to a layer-2 repeater device. In each room. Connectivity is maintained to the network with all of the benefits of the configured VLAN in terms of QoS. Connecting to a layer-2 repeater device can cause certain addresses to not be mapped to their respective VLAN if they are not correctly configured in the MAC-VLAN configuration database. You can configure the source MAC address-to-VLAN mapping either offline or dynamically on the switch. • Partial configurations of the MAC to VLAN database can be downloaded to the switch using the timed download configuration feature. If a repeater device is connected to a MAC-Based VLAN port. Upon removal of the configured MAC-to-VLAN endstation. routing. MAC-Based VLAN Guidelines When using the MAC-to-VLAN mapping.MAC-Based VLANs MAC-Based VLANs MAC-Based VLANs allow physical ports to be mapped to a VLAN based on the source MAC address learned in the FDB. any endstation that is attached to the repeater can be mapped to that VLAN while the configured endstation is active in that VLAN. the following configuration allows MAC 00:00:00:00:00:aa to enter into the VLAN only on ports 10 and 11 because of membership in group 100: * Summit48:50 # show mac Port Vlan 10 MacVlanDiscover 11 MacVlanDiscover 12 MacVlanDiscover 13 MacVlanDiscover 14 MacVlanDiscover Total Entries in Database:2 Mac Vlan 00:00:00:00:00:aa sales 00:00:00:00:00:01 sales 2 matching entries Group 100 100 any any any Group 100 any State Discover Discover Discover Discover Discover • The group “any” is equivalent to the group “0”. you could use this application for a roaming user who wants to connect to a network from a conference room. and the configured MAC-to-VLAN mapped station enters on the repeater. regardless of group association. the user plugs into one of the designated ports on the switch and is mapped to the appropriate VLAN. • Groups are used as a security measure to allow a MAC address to enter into a VLAN only when the group mapping matches the port mapping. As an example. Ports that are configured as “any” allow any MAC address to be assigned to a VLAN. This feature allows you to designate a set of ports that have their VLAN membership dynamically determined by the MAC address of the end station that plugs into the physical port.

If this is attempted. the configuration is automatically downloaded immediately after booting. use the following command: show switch 94 Summit 200 Series Switch Installation and User Guide . The MAC address 00:00:00:00:00:02 has a group number of “any” or “0” associated with it. • A MAC address cannot be configured to associate with more than 1 VLAN. • The MAC-to-VLAN mapping can only be associated with VLANs that exist on the switch. • The MAC-to-VLAN database is stored in memory. use the following command: download configuration every <hour:minute> To display timed download information. the the VLAN associations are lost during a reboot and you must perform an incremental download of the MAC-to-VLAN database to recover the VLAN associations. The MAC address 00:00:00:00:00:03 has a group number of 200 associated with it and can only be inserted into ports 18 through 20. use the following command: config download server [primary | secondary] [<host_name> | <ip_address>] <filename> To enable timed interval downloads. a timed TFTP configuration download allows you to download incremental configuration files from a primary or secondary server at specified time intervals. allowing it to be plugged into any port that is in MacVlanDiscover mode (ports 10-15 in this case). It is not stored in NVRAM.

For more information about setting the aging time. • Nonaging entries—If the aging time is set to zero. nonaging entries. its entry is deleted from the database. This prevents the database from becoming full with obsolete entries by ensuring that when a device is removed from the network. after a period of time (aging time). an identifier for the port on which it was received. It uses the information in this database to decide whether a frame should be forwarded or filtered. • Permanent entries—Permanent entries are retained in the database if the switch is reset or a power off/on cycle occurs. The following are four types of entries in the FDB: • Dynamic entries—Initially. refer to “Configuring FDB Entries” later in this chapter.8 Forwarding Database (FDB) This chapter describes the following topics: • Overview of the FDB on page 97 • Configuring FDB Entries on page 99 • Displaying FDB Entries on page 100 Overview of the FDB The switch maintains a database of all media access control (MAC) addresses received on all of its ports. Frames destined for devices that are not in the FDB are flooded to all members of the VLAN. All entries entered by way of the command-line Summit 200 Series Switch Installation and User Guide 97 .

The system updates its FDB with the source MAC address from a packet. The Summit 200 series switches support a maximum of 64 permanent entries. — A port is disabled. — A port is deleted from a VLAN. • You can enter and update entries using a MIB browser. The FDB treats the entry like a dynamic entry (it is learned. an SNMP Network Manager. — A port enters blocking state. the permanent entry store is not updated when any of the following take place: — A VLAN is deleted. For example. and the port identifier on which the source packet is received.Forwarding Database (FDB) interface are stored as permanent. — A port QoS setting is changed. 98 Summit 200 Series Switch Installation and User Guide . and so on). it can be aged out of the database. refer to Chapter 12.

Blackhole entries are never aged-out of the database. NOTE For more information on QoS. or the command-line interface (CLI). — A port mode is changed (tagged/untagged). Once created. How FDB Entries Get Added Entries are added into the FDB in the following two ways: • The switch can learn entries. Blackhole entries are treated like permanent entries in the event of a switch reset or power off/on cycle. the VLAN. • Blackhole entries—A blackhole entry configures the switch to discard packets with a specified MAC destination address. Blackhole entries are useful as a security measure or in special circumstances where a specific destination address must be discarded. — A port goes down (link down). — A VLAN identifier (VLANid) is changed. The switch applies the QoS profile as soon as the FDB entry is learned. permanent entries stay the same as when they were created.

These forwarded packets can also be modified by changing the 802. Incoming packets that match a rate limit access control list are allowed as long as they do not exceed a pre-defined rate. Each packet arriving on an ingress port is compared to the access list in sequential order and is either forwarded to a specified QoS profile or dropped. Using access lists has no impact on switch performance. Access policies are used primarily for security and quality of service (QoS) purposes. or modified by resetting their DiffServ code point.9 Access Policies This chapter describes the following topics: • Overview of Access Policies on page 101 • Using Access Control Lists on page 102 • Using Routing Access Policies on page 114 • Making Changes to a Routing Access Policy on page 118 • Removing a Routing Access Policy on page 118 • Routing Access Policy Commands on page 119 Overview of Access Policies Access policies are a generalized category of features that impact forwarding and route forwarding decisions.

The three categories of access policies are: • Access control lists • Rate limits • Routing access policies Access Control Lists Access control lists are used to perform packet filtering and forwarding decisions on incoming traffic. Rate Limits Rate limits are almost identical to access control lists.

but are sometimes more efficient and easier to implement than access lists. using different lists of values to examine packets. When you create an access list. Each access mask is created with a unique name and defines a list of fields that will be examined by any access control list that uses that mask (and by any rate limit that uses the mask). and a list of values to compare with the values found in the packet. Routing access policies can be used to ‘hide’ entire networks. Access masks can be shared multiple access control lists. such as RIP or OSPF. or to trust only specific sources for routes or ranges of routes. and an action to take for packets that match. you must specify a value for each of the fields that make up the access mask used by the list. An access mask consists of a combination of the following thirteen fields: • Ethernet destination MAC address • Ethernet source MAC address • VLANid • IP Type of Service (TOS) or DiffServ code point • Ethertype • IP protocol • IP destination address and netmask • Layer 4 destination port • IP source address and netmask • Layer 4 source port. Using Access Control Lists Each access control list consists of an access mask that selects which fields of each incoming packet to examine. 102 Summit 200 Series Switch Installation and User Guide . or ICMP type and/or ICMP code • TCP session initiation bits (permit-established keyword) • Egress port • Ingress ports An access mask can also have an optional. The capabilities of routing access policies are specific to the type of routing protocol involved. Access Masks There are between twelve and fourteen access masks available in the Summit 200 series switch.Access Policies Routing Access Policies Routing access policies are used to control the advertisement or recognition of routing protocols. The following sections describe how to use access control lists. unique precedence number associated with it. depending on which features are enabled on the switch. Access Lists Each entry that makes up an access list contains a unique name and specifies a previously created access mask. The access list also includes a list of values to compare with the incoming packets.

When you create a rate limit. You can send the packet to a particular QoS profile. Additionally.1p value and/or DiffServe code point. On a 1000 Mbps port (Gigabit Ethernet uplink port). • Permit with rewrite—Forward the packet. 24. a rate limit includes a list of values to compare with the incoming packets and an action to take for packets that match. due to hardware constraints. For packets that match a particular list and arrive at a rate that exceeds the limit. 16. which is to say. and modify the packet’s 802. you can specify the following actions: • Drop—Drop the packets. you can configure the rate limit value in the range from 1 Mbps to 100 Mbps in 1 Mbps increments. On a 100 Mbps port (100BASE-TX). Each port will have its own rate limit defined separately. you can specify the following action: • Permit—Forward the packet. Summit 200 Series Switch Installation and User Guide 103 . and arrive at a rate below the limit. NOTE The rate limit specified in the command line does not precisely match the actual rate limit imposed by the hardware. You can send the packet to a particular QoS profile. 3. but modify the packet’s DiffServe code point. if required for your implementation. Rate Limits Each entry that makes up a rate limit contains a unique name and specifies a previously created access mask. the rate limit value can be set at 1. and modify the packet’s 802. For packets that match a particular list. which is to say the rate limit value can be set at 8. you can specify the following actions: • Drop—Drop the packets. 32 … 1000 Mbps. Matching packets are not forwarded. Excess packets are not forwarded. a rate limit specifies an action to take when matching packets arrive at a rate above the limit you set. you must specify a value for each of the fields that make up the access mask used by the list. a rate limit can only be applied to a single port. NOTE Unlike an access list. • Permit-established—Drop the packet if it would initiate a new TCP session (see. “The permit-established Keyword” on page 104). Like an access list. you can configure the rate limit value in the range from 8 Mbps to 1000 Mbps in increments of 8 Mbps.Using Access Control Lists For packets that match a particular access control list. • Permit—Forward the packet. See the release notes for the exact values of the actual rate limits. 4 … 100 Mbps. 2.1p value and/or DiffServe code point.

the default rule is used to determine whether the packet is forwarded or dropped. If the resulting actions of all the matches do not conflict. the actions of the access list using the higher precedence access mask are applied. the fields of the packet corresponding to an access mask are compared with the values specified by the associated access lists to determine a match. It is possible that a packet will match more than one access control list. and so on.2. The following example shows an access control list that is used to specify an default rule to explicitly deny all traffic: create access-mask ingress_mask ports precedence 25000 create acess-list DenyAll ingress_mask ports 2-26 deny Once the default behavior of the access control list is established. but an access mask without a precedence specified has a higher precedence than any access mask with a precedence specified.1. the default behavior is to forward the packet. If no default rule is specified.x subnet even while the above default rule is in place: create access-mask ip_src_mask source-ip/24 precedence 1000 create access-list TenOneTwo ip_src_mask source-ip 10.Access Policies How Access Control Lists Work When a packet arrives on an ingress port. the packet is dropped. you can create additional entries using precedence numbers. Session initiation can be explicitly blocked using this keyword. Access Mask Precedence Numbers The access mask precedence number determines the order in which each rule is examined by the switch and is optional. When a match is found. The first access mask defined without a specified precedence has the highest precedence.2. they will all be carried out. Specifying a Default Rule You can specify a default access control list to define the default access to the switch. If the list is of type permit.0/24 permit The permit-established Keyword The permit-established keyword is used to directionally control attempts to open a TCP session. If no other access control list entry is satisfied. with the number 1 having the highest precedence. Access control list entries are evaluated from highest precedence to lowest precedence. Precedence numbers range from 1 to 25. If the access list is of type deny.1. You should use an access mask with a low precedence for the default rule access control list. you should not apply this rule to the Summit 200 series switch port used as a management port. Subsequent masks without a specified precedence have a lower precedence. The following access control list example shows an access control list that will forward traffic from the 10. NOTE If your default rule denies traffic. 104 Summit 200 Series Switch Installation and User Guide . the packet is processed.1p value and the DiffServe code point. the packet is forwarded. If there is a conflict.600. A permit access list can also apply a QoS profile to the packet and modify the packet’s 802.

When the feature is disabled.. for a total of 1014 rules (254*3+126*2). Access List. you must delete the entry and retype it.. the system will use one access mask. you must supply a unique name using the create command. and has the SYN=1 and ACK=0 flags set. use the following command: create access-list <name> . leaving a maximum of 13 user-definable access masks.Using Access Control Lists NOTE For an example of using the permit-established keyword. To modify an existing entry. a global rule (an access control list using an access mask without “ports” defined). and rate limits. reducing the number available. access lists. Three access masks are constantly used by the system. use the following command: create access-mask <name> . The permit-established keyword denies the access control list. This number is part of the total access control list rules (1014). the mask will again be available. For access lists and rate limits. Maximum Entries If you try to create an access mask when no more are available. Most user entered access list commands will require multiple rules on the hardware.. will require 5 rules. The features are: • RIP • IGMP or OSPF (both would share a single mask) • DiffServ examination • QoS monitor The maximum number of access list allowed by the hardware is 254 for each block of eight 10/100 Mbps Ethernet ports and 126 for each Gbps Ethernet port. For example. Adding Access Mask. However.. Having a permit-established access control list blocks all traffic that matches the TCP source/destination.. To add a rate limit entry. one for each of the 5 blocks of ports on the hardware. you must specify an access mask to use. and Rate Limit Entries Entries can be added to the access masks. For each of the following features that you enable. and supply a number of optional parameters (see Table 30 for the full command syntax). the system will issue a warning message. To add an access list entry. Summit 200 Series Switch Installation and User Guide 105 . refer to “Using the Permit-Established Keyword” on page 110.. The maximum number of rate-limiting rules allowed is 315 (63*5). To add an access mask entry. enabling some features causes the system to use additional access masks. use the following command: create rate-limit <name> . To add an entry. or create a new entry with a new unique name.

• Deny—The deny access profile mode denies the operation. Three modes are available: • Permit—The permit access profile mode permits the operation. the operation is implicitly denied. To configure the access profile mode. If no match is found. Once a match is found. Each entry must have a permit or deny attribute. depending on the configuration of the matched entry.Access Policies Using Routing Access Policies To use routing access policies. If the operation does not match any entries in the list. deny. You must give the access profile a unique name (in the same manner as naming a VLAN. the operation is denied. • None—Using the none mode. as long as it matches any entry in the access profile. If it does not match all specified entries in the list. use the following command: create access-profile <access_profile> type ipaddress Configuring an Access Profile Mode After the access profile is created. protocol filter. The operation is compared with each entry in the list. you must perform the following steps: 1 Create an access profile. you must configure the access profile mode. or Spanning Tree Domain). 3 Add entries to the access profile. 2 Configure the access profile to be of type permit. To create an access profile. 114 Summit 200 Series Switch Installation and User Guide . An access profile has a unique name and contains a list of IP addresses and associated subnet masks. The access profile mode determines whether the items in the list are to be permitted access or denied access. or none. as long as it matches any entry in the access profile. Creating an Access Profile The first thing to do when using routing access policies is to create an access profile. configure the access profile. use the following command: config access-profile <access_profile> mode [permit | deny | none] Adding an Access Profile Entry Next. using the following command: config access-profile <access_profile> add {<seq_number>} {permit | deny} [ipaddress <ipaddress> <mask> {exact}] The following sections describe the config access-profile add command. the operation is either permitted or denied. Entries are IP addresses and subnet masks 4 Apply the access profile. the operation is permitted. the access profile can contain a combination of permit and deny entries.

The keyword exact can be used when you wish to match only against the subnet address. If you do not specify a sequence number. the address 141. For example. entries are sequenced in the order they are added. this forms an access policy. a reverse mask specifies the part of the address that must match the IP address to which the profile is applied. use a mask of /32 (for example. it is added as a permit entry.28/32). Each entry is assigned a value of 5 more than the sequence number of the last entry. A reverse mask indicates the bits that are significant in the IP address.24. the switch can be configured to use an access profile to determine: • Trusted Neighbor—Use an access profile to determine trusted RIP router neighbors for the VLAN on the switch running RIP. To configure a trusted neighbor policy.Using Routing Access Policies Specifying Subnet Masks The subnet mask specified in the access profile command is interpreted as a reverse mask. but the configuration is more tricky. Routing Access Policies for RIP If you are using the RIP protocol. Permit and Deny Entries If you have configured the access profile mode to be none. Sequence Numbering You can specify the sequence number for each access profile entry. If you do not specify the entry type. use the following command: config rip vlan [<name> | all] trusted-gateway [<access_profile> | none] • Import Filter—Use an access profile to determine which RIP routes are accepted as valid routes.251. 141.24.128.10. When an access profile is applied to a protocol function (for example. This policy can be combined with the trusted neighbor policy to accept selected routes only from a set of trusted neighbors.24. A profile can be used by multiple routing protocol functions or VLANs. the export of RIP routes) or a VLAN. and ignore all addresses within the subnet.251. apply it to one or more routing protocols or VLANs. To configure an import filter policy. use the following command: config rip vlan [<name> | all] import-filter [<access_profile> | none] Summit 200 Series Switch Installation and User Guide 115 . If you configure an IP address that is an exact match that is specifically denied or permitted. it is not necessary to specify a type for each entry. 141. In other words. If you have configured the access profile mode to be permit or deny.251. you must specify each entry type as either ‘permit’ or ‘deny’. Deleting an Access Profile Entry To delete an access profile entry.0/24).128/27 represents any host from subnet 141.251. then configure the mask to cover only the subnet portion (for example. the same logic applies. but a protocol function or VLAN can use only one access profile. If the IP address represents all addresses in a subnet address that you want to deny or permit. use the following command: config access-profile <access_profile> delete <seq_number> Applying Access Profiles Once the access profile is defined. If you are using off-byte boundary subnet masking.

The IP address of the local interface connected to the corporate backbone is 10.1. The RIP protocol is used to communicate with other routers on the network. using the following command: config rip vlan [<name> | all] export-filter [<access_profile> | none] Examples In the example shown in Figure 21.0.1.10/24. The remote router that connects to the Internet has a local interface connected to the corporate backbone.10/32 rip vlan backbone trusted-gateway nointernet 116 Summit 200 Series Switch Installation and User Guide .0.0. the Internet router does not have the best routes for other local subnets).Access Policies • Export Filter—Use an access profile to determine which RIP routes are advertised into a particular VLAN.2.0.

Access policies for OSPF are intended to extend the existing filtering and security capabilities of OSPF (for example. the switch can be configured to use an access profile to determine any of the following: • Inter-area Filter—For switches configured to support multiple OSPF areas (an ABR function).0/24). if the administrator wants to restrict any user belonging to the VLAN Engsvrs from reaching the VLAN Sales (IP address 10. Routing Access Policies for OSPF Because OSPF is a link-state protocol.1.1. those routes will remain until the associated LSAs in that area time-out. use the following command: config ospf area <area_id> interarea-filter [<access_profile> | none] • External Filter—For switches configured to support multiple OSPF areas (an ABR function). the access policies associated with OSPF are different in nature than those associated with RIP. the additional access policy commands to build the access policy would be: create config config config access-profile nosales ipaddress access-profile nosales mode deny access-profile nosales add 10. To configure an inter-area filter policy. an access profile can be applied to an OSPF area that filters a set of OSPF external routes from being advertised into that area. As a result.2. use the following command: config ospf direct-filter [<access_profile> | none] Example Figure 22 illustrates an OSPF network that is similar to the network used previously in the RIP example.1. • ASBR Filter—For switches configured to support RIP and static route re-distribution into OSPF. Summit 200 Series Switch Installation and User Guide 117 . use the following command: config ospf area <area_id> external-filter [<access_profile> | none] NOTE If any of the external routes specified in the filter have already been advertised.2. all routes to the Internet will be done through external routes. use the following command: config ospf asbr-filter [<access_profile> | none] • Direct Filter—For switches configured to support direct route re-distribution into OSPF. In this example. an access profile can be applied to an OSPF area that filters a set of OSPF inter-area routes from being sourced from any other areas.1.0/24 to the internal backbone.

Figure 23: NAT Overview Inside NAT switch Outside Private Network Outgoing Outgoing Internet Incoming Incoming EW_078 Summit 200 Series Switch Installation and User Guide 121 . This conversion is done transparently by having a NAT device rewrite the source IP address and Layer 4 port of the packets. typically public Internet IP addresses.

Using IP addresses within these ranges prevents addressing conflicts with public Internet sites to which you want to connect. which corresponds to the public (probably Internet) IP addresses you want the inside addresses translated to. The ranges are as follows: • • • 10. it is strongly recommended that you use one of the reserved private IP address ranges for your inside IP addresses. 122 Summit 200 Series Switch Installation and User Guide .0. The mappings between inside and outside IP addresses are done via rules that specify the IP subnets involved and the algorithms used to translate the addresses. you must configure at least two separate VLANs involved. form a unique identifier which allows hosts (as well as the NAT switch) to distinguish between separate conversations.0. Multiple rules per outside VLAN are allowed. assuming that the rules and routing are set up properly.0/8—Reserved Class A private address space 172. NOTE The NAT modes in ExtremeWare support translating traffic initiating only from inside addresses. Any unmatched traffic will be routed normally and not be translated. The other type of VLAN is configured as outside. a single inside VLAN can use any number of different outside VLANs. Similarly. To configure a VLAN as an inside or outside VLAN. Both TCP and UDP have Layer 4 port numbers ranging from 1 to 65535.168. One VLAN is configured as inside. Any number of inside VLANs can use a single outside VLAN.0.0.0/16—Reserved Class C private address space Configuring VLANs for NAT You must configure each VLAN participating in NAT as either an inside or outside VLAN. Internet IP Addressing When implementing NAT in an Internet environment. use the following command: config nat vlan <name> [inside | outside | none] When a VLAN is configured to be inside. Because all traffic destined for an outside VLAN runs through the central processing unit (CPU). NAT rules are associated with a single outside VLAN. in combination with the IP addresses. and corresponds to the private IP addresses you would like to translate into other IP addresses. These ranges have been reserved specifically for networks not directly attached to the Internet. The NAT switch maintains a connection table to map the return packets on the outside VLAN back into their corresponding inside sessions. These Layer 4 ports.Network Address Translation (NAT) You can configure NAT to conserve IP address space by mapping a large number of inside (private) addresses to a much smaller number of outside (public) addresses. it cannot run at line-rate. traffic from that VLAN destined for an outside VLAN is translated only if it has a matching NAT rule. NAT operates by replacing the inside IP packet’s source IP and Layer 4 port with an outside IP and Layer 4 port. In implementing NAT.0/12—Reserved Class B private address space 192. assuming that you have created proper rules.16. The rules take effect in the order they are displayed using the show command.

the NAT device uses ports off of the next outside IP address. you would need to make several rules using the same inside and outside IP addresses. so it is possible to map specific source Layer 4 port ranges on the inside to specific outside source ranges. • • • • Static mapping Dynamic mapping Port-mapping Auto-constraining Static Mapping When static mapping is used. it does not make efficient use of the external address space. Port-mapping Port-mapping gives you the most efficient use of the external address space. ICMP traffic is not translated in this mode. NAT Modes There are four different modes used to determine how the outside IP addresses and Layer 4 ports are assigned. it cannot run at line-rate. it routes all traffic destined for inside VLANs. Summit 200 Series Switch Installation and User Guide 123 . this may cause a small performance penalty. one for each Layer 4 port range. The outside IP addresses are allocated on a first-come. Because the routed traffic runs through the CPU. ICMP traffic is translated and allowed to pass. Because this mode does not rely on Layer 4 ports. The Layer 4 ports are not changed. only the IP address is rewritten. This guarantees that no single inside host can prevent other traffic from flowing through the NAT device. The limitation is based on the ratio of inside to outside IP addresses. Because this mode requires a 1-to-1 mapping of internal to external addresses. When the last session for a specific inside IP address closes. Because this mode does not rely on Layer 4 ports.Configuring VLANs for NAT When a VLAN is configured to be outside. first-serve basis to the inside IP addresses. Some systems reserve certain port ranges for specific types of traffic. In this case. that outside IP address can be used by other hosts. When all ports on a given IP address are in use. the NAT device picks the next available source Layer 4 port on the first available outside IP address. Auto-constraining The auto-constraining algorithm for port-mapping limits the number of outside Layer 4 ports a single inside host can use simultaneously. As each new connection is initiated from the inside. all NAT functions are disabled and the VLAN operates normally. Dynamic Mapping Dynamic mapping is similar to static mapping in that the Layer 4 ports are not rewritten during translation. ICMP traffic is translated and allowed to pass. each inside IP address uses a single outside IP address. When a VLAN is configured to be none. The outside IP address and Layer 4 port space is evenly distributed to all possible inside hosts. Dynamic mapping is different in that the number of inside hosts can be greater than the number of outside hosts. However. You must add a dynamic NAT rule for the same IP address range to allow for ICMP traffic. But it is useful when you have a small number of hosts that need to have their IP addresses rewritten without conflicting with other hosts.

<ipaddress>] {[tcp | udp | both] [portmap {<min> . so that the switch can proxy the address resolution protocol (ARP) for those addresses. You must add a dynamic NAT rule for the same IP address range to allow for ICMP traffic. The options specified on the NAT rule determine the algorithm used to translate the inside IP addresses to the outside IP addresses. The range of number is 1 to 65535. the first rule to match is processed.

In this example, there is one EAPS domain with its own control VLAN running on the ring labeled LHS and another EAPS domain with its own control VLAN running on the ring labeled RHS. A data VLAN that spans both rings acts as a protected VLAN to both EAPS domains. Switches S 5 and S 10 will have two instances of EAPS domains running on them: one for each ring. Summit 200 series switches can be deployed in a multi-ring EAPS topology subject to these guidelines: • Summit 200 series switches can be used as any of the EAPS nodes in the ring except as a node that interconnects the two rings. For example, in the example shown in Figure 27, nodes S 5 and S 10 cannot be Summit 200 series switches. Summit 200 series switches support EAPS Version 1 (EAPSv1) and only support a single EAPS domain per switch. • Depending on the network topology and the versions of EAPS (EAPSv1 vs. EAPSv2) running on the other EAPS nodes, there might be a requirement to configure STP support for EAPSv1 to prevent super loops—in the event of a break in the common link between the nodes interconnecting the rings. For example, in the example shown in Figure 27, a break in the link between nodes S 5 and S 10 would result in a super loop. — Case 1: Summit 200 series switches on a single ring. In this case, EAPSv1 requires no STP support. — Case 2: Summit 200 series switches on a multi-ring network along with ring-connecting switches not running EAPSv2. In this case, the Summit 200 series switches still cannot be ring-connecting nodes, and this implementation requires configuring EAPSv1 plus STP support to prevent super loops. This configuration process is described in the EAPS chapter of the ExtremeWare Software User Guide, Version 7.0.0. — Case 3: Summit 200 series switches on a multi-ring network along with ring-connecting switches running EAPSv2. In this case, the Summit 200 series switches still cannot be ring-connecting nodes, but configuring EAPSv1 plus EAPSv2 means that the “EAPS awareness” of the ring-connecting switches would prevent problems with super-loops without requiring STP support. This configuration process is described in the EAPS chapter of the ExtremeWare Software User Guide, Version 7.1.0.

Commands for Configuring and Monitoring EAPS

Creating and Deleting an EAPS Domain
Each EAPS domain is identified by a unique domain name. NOTE Only a single EAPS domain per switch is supported by Summit 200 series switches. To create an EAPS domain, use the following command:
create eaps <name>

The name parameter is a character string of up to 32 characters that identifies the EAPS domain to be created. EAPS domain names and VLAN names must be unique; Do not use the same name string to identify both an EAPS domain and a VLAN.The following command example creates EAPS domain eaps_1 on the switch:
create eaps eaps_1

To delete an EAPS domain, use the following command:
delete eaps <name>

The following command example deletes the EAPS domain eaps_1:
delete eaps eaps_1

Defining the EAPS Mode of the Switch
To configure the EAPS node type of the switch, use the following command:
config eaps <name> mode [master | transit]

One node on the ring must be configured as the master node for the specified domain; all other nodes on the ring are configured as transit nodes for the same domain. The following command example identifies this switch as the master node for the domain named eaps_1.
config eaps eaps_1 mode master

The following command example identifies this switch as a transit node for the domain named eaps_1.
config eaps eaps_1 mode transit

Configuring EAPS Polling Timers
To set the values of the polling timers the master node uses for the EAPS health-check packet that is circulated around the ring for an EAPS domain, use the following command:
config eaps <name> [hellotime <seconds> | failtime <seconds>]

NOTE This command applies only to the master node. If you configure the polling timers for a transit node, they will be ignored. If you later reconfigure that transit node as the master node, the polling timer values will be used as the current values.

Ethernet Automatic Protection Switching

Use the hellotime keyword and its associated seconds parameter to specify the amount of time the master node waits between transmissions of health-check packets on the control VLAN. seconds must be greater than 0 when you are configuring a master node. The default value is one second.

NOTE Increasing the hellotime value keeps the processor from sending and processing too many health-check packets. Increasing the hellotime value should not affect the network convergence time, because transit nodes are already sending “link down” notifications. Use the failtime keyword and its associated seconds parameter to specify the amount of time the master node waits before declaring a failed state and opens the logically blocked VLANs on the secondary port. seconds must be greater than the configured value for hellotime. The default value is three seconds.

NOTE Increasing the failtime value provides more protection against frequent “flapping” between the complete state and the failed state by waiting long enough to receive a health-check packet when the network is congested.

NOTE When the master node declares a failed state, it also flushes its forwarding database (FDB) and sends a “flush FDB” message to all the transit switches on the ring by way of the control VLAN. The reason for flushing the FDB is so that the switches can relearn the new directions to reach Layer 2 end stations via the reconfigured topology. The following command examples configure the hellotime value for the EAPS domain “eaps_1” to 2 seconds and the failtime value to 10 seconds.
config eaps eaps_1 hellotime 2 config eaps eaps_1 failtime 10

Configuring the Primary and Secondary Ports
Each node on the ring connects to the ring through two ring ports. As part of the protection switching scheme, one port must be configured as the primary port; the other must be configured as the secondary port. If the ring is complete, the master node prevents a loop by logically blocking all data traffic in the transmit and receive directions on its secondary port. If the master node subsequently detects a break in the ring, it unblocks its secondary port and allows data traffic to be transmitted and received through it. To configure a node port as primary or secondary, use the following command:
config eaps <name> [primary | secondary] port <port number>

The following command example adds port 2 of the switch to the EAPS domain “eaps_1” as the primary port.
config eaps eaps_1 primary port 2

Commands for Configuring and Monitoring EAPS

Configuring the EAPS Control VLAN
You must configure one control VLAN for each EAPS domain. The control VLAN is used only to send and receive EAPS messages. NOTE A control VLAN cannot belong to more than one EAPS domain. To configure the EAPS control VLAN for the domain, use the following command:
config eaps <name> add control vlan <name>

NOTE To avoid loops in the network, the control VLAN must NOT be configured with an IP address, and ONLY ring ports may be added to the VLAN.

NOTE When you configure the VLAN that will act as the control VLAN, that VLAN must be assigned a QoS profile of Qp8, and the ring ports of the control VLAN must be tagged. By assigning the control VLAN a QoS profile of Qp8, you ensure that EAPS control VLAN traffic is serviced before any other traffic and that control VLAN messages reach their intended destinations. For example, if the control VLAN is not assigned the highest priority and a broadcast storm occurs in the network, the control VLAN messages might be dropped at intermediate points. Assigning the control VLAN the highest priority prevents dropped control VLAN messages.

NOTE Because the QoS profiles Qp7 and Qp8 share the same hardware queue in the Summit 200 series switch, you must limit the amount of traffic that uses these profiles; otherwise, the Summit 200 series switch may drop EAPS control packets, preventing EAPS from operating reliably. The following command example adds the control VLAN “keys” to the EAPS domain “eaps_1.”
config eaps eaps_1 add control vlan keys

Configuring the EAPS Protected VLANs
You must configure one or more protected VLANs for each EAPS domain. The protected VLANs are the data-carrying VLANs. NOTE When you configure the VLAN that will act as a protected VLAN, the ring ports of the protected VLAN must be tagged (except in the case of the default VLAN).

you can specify the service level that a particular traffic type receives. Each hardware queue can be programmed by ExtremeWare with bandwidth limitation and prioritization parameters. Using Policy-based QoS. The switch contains separate hardware queues on every physical port. The bandwidth limitation and prioritization parameters that modify the forwarding behavior of the switch affect how the switch transmits traffic for a given hardware queue on a physical port.12 Quality of Service (QoS) This chapter covers the following topics: • Overview of Policy-Based Quality of Service on page 143 • Applications and Types of QoS on page 144 • Configuring QoS for a Port or VLAN on page 145 • Traffic Groupings on page 146 — MAC-Based Traffic Groupings on page 147 — Explicit Class of Service (802.

For example. Other applications deemed less critical can be limited so as to not consume excessive bandwidth. Summit 200 series switches support up to four physical queues per port. you can reserve sufficient bandwidth critical to this type of application. Overview of Policy-Based Quality of Service Policy-based QoS allows you to protect bandwidth for important categories of applications or specifically limit the bandwidth associated with less critical traffic.

Quality of Service (QoS) NOTE As with all Extreme switch products. Consider them as general guidelines and not strict recommendations. and sensitivity and impact of packet loss.” with the expectation that the end-stations will buffer significant amounts of video-stream data. Using even the most complex traffic groupings has no cost in terms of switch performance. you can monitor the performance of the application to determine if the actual behavior of the applications matches your expectations. The following applications are ones that you will most commonly encounter and need to prioritize: • Voice applications • Video applications • Critical database applications • Web browsing applications • File server applications General guidelines for each traffic type are given below and summarized in Table 36. followed by priority. with the exception that bandwidth requirements are somewhat larger. some applications can transmit large amounts of data for multiple streams in one “spike.

Voice Applications Voice applications typically demand small amounts of bandwidth. in the playback of stored video streams. priority. For example. Behavioral aspects to consider include bandwidth needs. sensitivity to latency and jitter. Critical Database Applications Database applications. depending on the encoding. This can present a problem to the network infrastructure. 144 Summit 200 Series Switch Installation and User Guide . QoS has no impact on switch performance. Once QoS parameters are set. because it must be capable of buffering the transmitted spikes where there are speed differences (for example. However. such as those associated with ERP. Key QoS parameters for video applications include minimum bandwidth. Video Applications Video applications are similar in needs to voice applications. the bandwidth must be constant and predictable because voice applications are typically sensitive to latency (inter-packet delay) and jitter (variation in inter-packet delay). It is very important to understand the needs and behavior of the particular applications you wish to protect or limit. and possibly buffering (depending upon the behavior of the application). going from Gigabit Ethernet to Fast Ethernet). typically do not demand significant bandwidth and are tolerant of delay. Applications and Types of QoS Different applications have different QoS requirements. The most important QoS parameter to establish for voice applications is minimum bandwidth. You can establish a minimum bandwidth using a priority less than that of delay-sensitive applications.

Half-duplex operation on links can make delivery of guaranteed minimum bandwidth impossible. In addition. and some packet loss. file serving typically poses the greatest demand on bandwidth. however small packet-loss may have a large impact on perceived performance due to the nature of TCP. large dataflows from the server to the browser client).

This level of packet filtering has no impact on performance. A traffic grouping is a classification of traffic that has one or more attributes in common.Quality of Service (QoS) Traffic Groupings Once a QoS profile is modified for bandwidth and priority. In general. you can prescribe the bandwidth management and priority handling for that traffic grouping. The supported traffic groupings are listed in Table 38. Traffic groupings are separated into the following categories for discussion: • Access list based information (IP source/destination. The four types of traffic groupings are described in detail on the following pages. By default. there is a predetermined precedence for which traffic grouping will apply. 146 Summit 200 Series Switch Installation and User Guide . The groupings are listed in order of precedence (highest to lowest). such as 802. you assign traffic a grouping to the profile.

For permanent destination MAC-based grouping. and the switch/port. and dynamically maps the end station name to the current IP address and switch/port. • For physical and logical groupings of a source port or VLAN. Dynamic Link Context System The Dynamic Link Context System (DLCS) is a feature that snoops WINS NetBIOS packets and creates a mapping between a user name. This information is available for use by ExtremeWare Enterprise Manager (EEM) version 2. as documented. This feature should only be used in conjunction with the EEM Policy System or ExtremeWare EPICenter Policy System. Traffic that matches a rate limit is constrained to the limit set in the access control list. re-apply the QoS profile to the static FDB entry. You can also save and reboot the switch. For DLCS to operate within ExtremeWare. clear the MAC FDB using the command clear fdb. the user or end station must allow for automatic DLCS updates.Quality of Service (QoS) • Priority • A list of all traffic groups to which the QoS profile is applied Additionally.

Based on the information in the packet. QoS information can be displayed from the traffic grouping perspective by using one or more of the following commands: • show fdb permanent—Displays destination MAC entries and their QoS profiles. DLCS can detect when an end station boots up or a user logs in or out. as the configuration must be in place before an entry is made in the MAC FDB. • show ports <portlist> info {detail}—Displays information including QoS information for the port. as documented. The following rules apply: • For destination MAC-based grouping (other than permanent). This command should also be issued after a configuration is implemented. You can also save and reboot the switch. the IP address or MAC address. Traffic Rate-Limiting The Summit 200 series switch rate-limiting method is based on creating a rate limit. • show switch—Displays information including PACE enable/disable information. the timing of the configuration change depends on the traffic grouping involved.

DLCS provides you with valuable information on a user’s location and associated network attributes.

you must explicitly delete configuration parameters from the EEM or ExtremeWare EPICenter Policy Applet user interface. Displays ports which are snooping WINS packets. This information is still stored in the policy-server. the command to add the WINS server is rejected. • IPQoS is not supported to a WINS server that is serving more than one VLAN. the information is lost. Table 43: DLCS Configuration Commands Command clear dlcs disable dlcs disable dlcs ports <port-number> enable dlcs enable dlcs ports <port-number> show dlcs Description Clears learned DLCS data. the old host-to-IP address mapping is never deleted. the old entry does not age out unless the host is rebooted or a user login operation is performed after the host is moved. if the switch is rebooted. and there are IPQoS rules defined for that server. To delete the information from the policy system. and the host is not immediately rebooted.Dynamic Link Context System DLCS Guidelines Follow these guidelines when using DLCS: • Only one user is allowed on one workstation at a given time. Enables snooping of DLCS packets. This is because the WINS server does not send NETBIOS packets on the network (these packets are address to itself). • Multiple IP-addresses can be learned on the same port. and re-add the switch to the Inventory Manager. Enables port on which DLCS packets are snooped. • DLCS mapping is flushed when a user logs in or logs out. If you attempt to add a WINS server to serve more than one VLAN. DLCS Commands The DLCS commands are described in Table 43. You must delete the mapping of the host-to-IP address through the EEM Policy Manager or ExtremeWare EPICenter Policy Manager. • When the host is moved from one port to another port on a switch. you can delete the switch that was rebooted from the list of managed devices in the EEM or EPICenter Inventory Applet. • DLCS information is dynamic. along with the data that has been learned. therefore. DLCS Limitations Consider the following limitations concerning data received from WINS snooping: • DLCS does not work for the WINS server. • A user can be logged into many workstations simultaneously. • DLCS is not supported on hosts that have multiple NIC cards. • An IP-address can be learned on only one port in the network at a given time. Summit 200 Series Switch Installation and User Guide 155 . As a workaround. Disables port on which DLCS packets are snooped. Disables snooping of DLCS packets. • When the IP address of a host is changed. or when an end-station is shutdown.

About RMON RMON is the common abbreviation for the Remote Monitoring Management Information Base (MIB) system defined by the Internet Engineering Task Force (IETF) documents RFC 1271 and RFC 1757.

History The History group provides historical views of network performance by taking periodic samples of the counters supplied by the Statistics group. Implementing RMON in the switch means that all ports can have security features enabled. which provides a mechanism for an automated response to certain occurrences. use the following command: [enable | disable] rmon 166 Summit 200 Series Switch Installation and User Guide . statistics can be related to individual ports. to send an SNMP trap to the receivers listed in the trap receiver table. multicasts. The RMON traps are defined in RFC 1757 for rising and falling thresholds. events can trigger other actions. Effective use of the Events group saves you time. Also. because a probe must be able to see all traffic. alarm thresholds can be autocalibrated or set manually. An event is triggered by an RMON alarm. Configuring RMON RMON requires one probe per LAN segment. to log the event. Alarms The Alarms group provides a versatile. In addition. Rather than having to watch real-time graphs for important occurrences. The group is useful for analysis of traffic patterns and trends on a LAN segment or VLAN. you can depend on the Event group for notification. Extreme’s approach has been to build an inexpensive RMON probe into the agent of each system. Therefore. Both rising and falling thresholds are supported. a stand-alone probe must be attached to a nonsecure port. or to both log and send a trap. and errors on a LAN segment or VLAN. broadcasts. and standalone RMON probes traditionally have been expensive. To enable or disable the collection of RMON statistics on the switch. Alarms inform you of a network performance problem and can trigger automated action responses through the Events group. Through the SNMP traps. The group features user-defined sample intervals and bucket counters for complete customization of trend analysis. Events The Events group creates entries in an event log and/or sends SNMP traps to the management workstation. For example. The action taken can be configured to ignore it. and to establish baseline information indicating normal operating parameters. Information from the Statistics group is used to detect changes in traffic and error patterns in critical areas of the network. This allows RMON to be widely deployed around the network without costing more than traditional network management. bytes. general mechanism for setting threshold and sampling intervals to generate events on any RMON variable. The switch accurately maintains RMON statistics at the maximum line rate of all of its ports. and thresholds can be on the absolute value of a variable or its delta value.Status Monitoring and Statistics Statistics The RMON Ethernet Statistics group provides traffic and error statistics showing packets.

Overview of the Spanning Tree Protocol STP is a bridge-based mechanism for providing fault tolerance on networks. then all those VLANs must belong to the same STPD. Spanning Tree Domains The switch can be partitioned into multiple virtual bridges. Each virtual bridge can run an independent Spanning Tree instance. one or more VLANs can be assigned to it.

Spanning Tree Protocol (STP) The key points to remember when configuring VLANs and STP are: • Each VLAN forms an independent broadcast domain • STP blocks paths to create a loop-free environment • When STP blocks a path. You must remove all VLANs associated with the STP before deleting the STPD. switch Z. and switch M. STPD BPDU Tunneling You can configure ExtremeWare to allow a BDPU to traverse a VLAN without being processed by STP. This is known as BPDU tunneling. • Marketing is defined on all switches (switch A.

Each host using the IP unicast routing functionality of the switch must have a unique IP address assigned. IP unicast routing. refer to the following publications for additional information: • RFC 1256—ICMP Router Discovery Messages • RFC 1812—Requirements for IP Version 4 Routers NOTE For more information on interior gateway protocols. It exchanges routing information with other routers on the network using either the Routing Information Protocol (RIP) or the Open Shortest Path First (OSPF) protocol. the default gateway assigned to the host must be the IP address of the router interface. The switch dynamically builds and maintains a routing table.

35. Personnel belongs to the IP network 192.35.35. the router interface for Finance is assigned the IP address 192.36.35.207. Traffic within each VLAN is switched using the Ethernet MAC addresses.207.35. NOTE Each IP address and mask assigned to a VLAN must represent a unique IP subnet. Finance belongs to the IP network 192.13 192. its router interface is assigned IP address 192.1.0 Finance 192.207.207. Figure 32: Routing between VLANs 192.0. Ports 2 and 4 are assigned to Finance.207.14 EW_090 178 Summit 200 Series Switch Installation and User Guide .36. a switch is depicted with two VLANs defined.1 192. Traffic between the two VLANs is routed using the IP addresses. As you create VLANs with IP addresses belonging to different IP subnets.0.35. ports 3 and 5 are assigned to Personnel. Both the VLAN switching and IP routing function occur within the switch.36.207.IP Unicast Routing Router Interfaces The routing software and hardware routes IP traffic between router interfaces.206. you can also choose to route between the VLANs.207.36.36.207.12 192.1 192.207.36.11 192.207. A router interface is simply a VLAN that has an IP address assigned to it. In Figure 32.207.1.0 Personnel 2 3 4 5 192. Finance and Personnel. You cannot configure the same IP address and subnet on different VLANs.

Using dynamic routes. the routing table contains only networks that are reachable. the invalid default route entry remains. Dynamic Routes Dynamic routes are typically learned by way of RIP or OSPF. as configured by the administrator NOTE If you define a default route and then delete the VLAN on the subnet associated with the default route. Summit 200 Series Switch Installation and User Guide 179 . using one of the following commands: [enable | disable] rip export static [enable | disable] ospf export static The default setting is disabled. Routers that use RIP or OSPF exchange information in their routing tables in the form of advertisements. • Statically. as determined by the routing protocol. Static routes are used to reach networks not advertised by routers. by way of interface addresses assigned to the system — By other static routes. You must manually delete the configured default route. If these are still equal. An IP subnet is associated with a single VLAN by its IP address and subnet mask. to control which routes you want advertised by the router. by way of routes entered by the administrator: — Default routes. by way of routing protocol packets or by ICMP redirects exchanged with other routers.Overview of IP Unicast Routing Populating the Routing Table The switch maintains an IP routing table for both network routes and host routes. A static route must be associated with a valid IP subnet. Multiple Routes When there are multiple. The table is populated from the following sources: • Dynamically. Dynamic routes are aged out of the table when an update for the network is not received for a period of time. conflicting choices of a route to a particular destination. configured by the administrator — Locally. Static routes can also be used for security reasons. the router picks the route with the longest matching network mask. later in this chapter) • Static routes • Directly attached network interfaces that are not active. the router picks the route using the following criteria (in the order specified): • Directly attached network interfaces • ICMP redirects (refer to Table 55. If the VLAN is subsequently deleted. Static Routes Static routes are manually entered into the routing table. the static route entries using that subnet must be deleted manually. You can decide if you want all static routes to be advertised. Static routes are never aged out of the routing table.

Route sharing is useful only in instances where you are constrained for bandwidth. You can also configure the VLAN router interface to either forward and process all subnet-directed broadcast packets. To enable or disable broadcast packet processing. The latter option allows you to improve CPU forwarding performance by having upper layers. 180 Summit 200 Series Switch Installation and User Guide . if the packets have IP-options configured). To use IP route sharing. use the following command: [enable | disable] ipforwarding fast-direct-broadcast [vlan <vlan_name>] The entries are added to the IP forwarding table as standard entries and you can view them using the show ipfdb command. Traffic to these destinations is silently dropped. In OSPF. This allows the switch to forward subnet-directed broadcast packets at wire-speed. IP Route Sharing IP route sharing allows multiple equal-cost routes to be used concurrently. You can also configure blackhole routes. use the following command: [enable | disable] ipforwarding ignore-broadcast vlan <vlan_name> Proxy ARP Proxy Address Resolution Protocol (ARP) was first invented so that ARP-capable devices could respond to ARP Request packets on behalf of ARP-incapable devices. IP route sharing can be used with static routes or with OSPF routes. If multiple default routes have the same lowest metric. This is typically not the case using Extreme switches. the route that has the lowest metric is used. this capability is referred to as equal cost multipath (ECMP) routing. configure static routes and/or OSPF as you would normally. Proxy ARP can also be used to achieve router redundancy and simplify IP client configuration. use the following command: enable iproute sharing Next.IP Unicast Routing NOTE If you define multiple default routes. ExtremeWare supports unlimited route sharing across static routes and up to eight ECMP routes for OSPF. Using route sharing makes router troubleshooting more difficult because of the complexity in predicting the path over which the traffic will travel. Subnet-Directed Broadcast Forwarding You can enable or disable the hardware forwarding of subnet-directed broadcast IP packets. The switch supports proxy ARP for this type of network configuration. or to simply forward these packets after they have been added to the IP forwarding database. the system picks one of the routes. ignore broadcast packet processing (for example. such as UDP and TCP. The section describes some example of how to use proxy ARP with the switch. To enable or disable hardware forwarding.

255.0. In reality.0. you must configure the IP address and MAC address of the ARP-incapable device using the use the following command: config iparp add proxy <ipaddress> {<mask>} <mac_address> {always} Once configured.101.255. using its own MAC address. the switch formulates an ARP Response using the configured MAC address in the packet.67.67. Summit 200 Series Switch Installation and User Guide 181 . and the switch routes the packets to 100. For example. All subsequent data packets from 100.Relative Route Priorities ARP-Incapable Devices To configure the switch to respond to ARP Requests on behalf of devices that are incapable of doing so.255.101. the system responds to ARP Requests on behalf of the device as long as the following conditions are satisfied: • The valid IP ARP Request is received on a router interface.255. The switch is configured with the IP address 100. • The proxy ARP table entry indicates that the system should always answer this ARP Request. do not attempt any manipulation unless you are expertly familiar with the possible consequences.45.1 and a mask of 255. Proxy ARP Between Subnets In some networks. When the IP host tries to communicate with the host at address 100. the host communicates as if all devices are local.0. The switch is also configured with a proxy ARP entry of IP address 100.101.102.102. Relative Route Priorities Table 52 lists the relative priorities assigned to routes depending upon the learned source of the route.45. • The target IP address matches the IP address configured in the proxy ARP table. The switch answers on behalf of the device at address 100.0. CAUTION Although these priorities can be changed.103 and a mask of 255.102.101. without the always parameter. communication with devices outside of the subnet are proxied by the router.101.0 and mask 255.101.0.103 are sent to the switch. and sends out an IP ARP Request.101. Once all the proxy ARP conditions are met.67. Proxy ARP can be used so that the router answers ARP Requests for devices outside of the subnet.0. it is desirable to configure the IP host with a wider subnet than the actual subnet mask of the segment.45. an IP host is configured with a class B address of 100. As a result. the IP hosts communicates as if the two hosts are on the same subnet. regardless of the ingress VLAN (the always parameter must be applied).

RIP is a distance-vector protocol.

The biggest advantage of using RIP is that it is relatively simple to understand and implement. OSPF is a newer Interior Gateway Protocol (IGP). It is primarily intended for use in homogeneous networks of moderate size. Using a link-state protocol.Interior Gateway Routing Protocols OSPF is a link-state protocol. 194 Summit 200 Series Switch Installation and User Guide . To determine the best path to a distant network. • Faster convergence. and it has been the de facto routing standard for many years. no concept of link costs or delay. • Flat networks. Each router builds a shortest path tree. each router creates a unique routing table from summarized information obtained from neighboring routers. using itself as the root. verifying that all routers have a consistent network map. • Route updates multicast only when changes occur. no concept of areas or boundaries. including: • No limitation on hop count. RIP Versus OSPF The distinction between RIP and OSPF lies in the fundamental differences between distance-vector protocols and link-state protocols. • Support for load balancing to multiple routers based on the actual cost of the link. OSPF offers many advantages over RIP. The link-state protocol ensures that updates sent to neighboring routers are acknowledged by the neighbors. The details of RIP and OSPF are explained later in this chapter. Using a distance-vector protocol. • Support for hierarchical topologies where the network is divided into areas. Each router that data must traverse is considered to be one hop. including: • A limit of 15 hops between the source and destination networks. every router maintains an identical routing table created from information obtained from all routers in the autonomous system. • Slow convergence. and solves a number of problems associated with using RIP on today’s complex networks. • Routing decisions based on hop count. a router using RIP always selects the path that has the least number of hops. • A large amount of bandwidth taken up by periodic broadcasts of the entire routing table. NOTE Both RIP and OSPF can be enabled on a single VLAN. RIP has a number of limitations that can cause problems in large networks. Overview of RIP RIP is an Interior Gateway Protocol (IGP) first used in computer routing in the Advanced Research Projects Agency Network (ARPAnet) as early as 1969. based on the Dijkstra link-state algorithm.

defining it as unreachable. do not have their subnets advertised by RIP. a router advertises a route over the same interface that supplied the route. Route Advertisement of VLANs VLANs that are configured with an IP address. which allows for optimization of routes in certain environments. reducing the load on hosts that do not support routing protocols. Each routing table entry contains the following information: • IP address of the destination network • Metric (hop count) to the destination network • IP address of the next router • Timer that tracks the amount of time since the entry was last updated The router exchanges an update message with each neighbor every 30 seconds (default value). Split horizon omits routes learned from a neighbor in updates sent to that neighbor. even if it is not yet time for a regular update message to be sent. Summit 200 Series Switch Installation and User Guide 195 . but may also result in more RIP-related traffic. expands the functionality of RIP version 1 to include: • Variable-Length Subnet Masks (VLSMs). If a router does not receive an update message from its neighbor within the route timeout period (180 seconds by default). RIP version 2 packets can be multicast instead of being broadcast. Triggered Updates Triggered updates occur whenever a router changes the metric for a route. • Support for next-hop addresses. In this case. Poison Reverse Like split horizon. Split Horizon Split horizon is a scheme for avoiding problems caused by including routes in updates sent to the router from which the route was learned. called RIP version 2. This will generally result in faster convergence. or if there is a change to the overall routed topology (also called triggered updates).Overview of RIP Routing Table The routing table in a router using RIP contains an entry for every known destination network. the router assumes the connection between it and its neighbor is no longer available. and it is required to send an update message immediately. but are configured to not route IP or are not configured to run RIP. but the route uses a hop count of 16. poison reverse is a scheme for eliminating the possibility of loops in the routed topology. Only those VLANs that are configured with an IP address and are configured to route IP and run RIP have their subnets advertised. • Multicasting. RIP Version 1 Versus RIP Version 2 A new version of RIP.

also known as an autonomous system (AS). and cannot be a designated or a backup designated router.Interior Gateway Routing Protocols NOTE If you are using RIP with supernetting/Classless Inter-Domain Routing (CIDR). you must use RIPv2 only. In addition. Link-State Database Upon initialization. The cost of a route is described by a single metric. When several equal-cost routes to a destination exist. Overview of OSPF OSPF is a link-state protocol that distributes routing information between routers belonging to a single IP domain. Once all LSAs are received. the router uses the LSDB to calculate the best routes for use in the IP routing table. LSAs are collected by each router and entered into the LSDB of each router. each router transmits a link-state advertisement (LSA) on each of its interfaces. each router constructs a tree of shortest paths. From the link-state database (LSDB). using itself as the root. each router maintains a database describing the topology of the autonomous system. Table 59 describes LSA type numbers. Any change in routing information is sent to all of the routers in the network. In a link-state routing protocol. RIP route aggregation must be turned off. Table 59: LSA Type Numbers Type Number 1 2 3 4 5 7 9 10 11 Description Router LSA Network LSA Summary LSA AS summary LSA AS external LSA NSSA external LSA Link local Area scoping AS scoping 196 Summit 200 Series Switch Installation and User Guide . OSPF uses flooding to distribute LSAs between routers. traffic can be distributed among them. The shortest path tree provides the route to each destination in the autonomous system. NOTE A Summit 200 series switch can support up to two non-passive OSPF interfaces. Each participating router has an identical database maintained from the perspective of that router. All routers within an area have the exact same LSDB.

The topology within an area is hidden from the rest of the autonomous system. support for opaque LSAs is auto-negotiated between OSPF neighbors. which maintains consistency. At minimum a well-interconnected subsection of your OSPF network needs to support opaque LSAs to maintain reliability of their transmission. A limit value of zero disables the functionality. timeout Specifies the timeout. you can disable opaque LSAs across the entire system using the following command: disable ospf capability opaque-lsa To re-enable opaque LSAs across the entire system. When the LSDB size limit is reached. Opaque LSAs Opaque LSAs are a generic OSPF mechanism used to carry auxiliary information in the OSPF database. To configure OSPF database overflow. Routing within the area is determined only by the topology of the area. Routers that do not support opaque LSAs do not store or flood them. Normally. Opaque LSAs are most commonly used to support OSPF traffic engineering. in seconds. we recommend that all routers on your OSPF network support opaque LSAs. Areas OSPF allows parts of a network to be grouped together into areas. OSPF database overflow flushes the same LSAs from all the routers. after which the system ceases to be in overflow state. use the following command: config ospf ase-limit <number> {timeout <seconds>} where: number Specifies the number of external LSAs (excluding the default LSAs) that the system supports before it goes into overflow state. Hiding this information enables a significant reduction in LSA traffic. Consistency is achieved by: • Limiting the number of external LSAs in the database of each router. A timeout value of zero leaves the system in overflow state until OSPF is disabled and re-enabled. In the event that you experience interoperability problems. which ensures that all routers have a consistent view of the network. • Ensuring that all routers have identical LSAs. use the following command: enable ospf capability opaque-lsa If your network uses opaque LSAs. and reduces the computations needed to maintain the LSDB. Summit 200 Series Switch Installation and User Guide 197 .Overview of OSPF Database Overflow The OSPF database overflow feature allows you to limit the size of the LSDB and to maintain a consistent LSDB across all the routers in the domain. OSPF database overflow flushes LSAs from the LSDB.

When a VLAN is configured to run OSPF. When designing networks.0.0. you must configure the area for the VLAN. Backbone Area (Area 0. use the following command: config ospf vlan <name> area <areaid> If this is the first instance of the OSPF area being used. also called the backbone. but have the following two additional capabilities: • External routes originating from an ASBR connected to the NSSA can be advertised within the NSSA.Interior Gateway Routing Protocols The three types of routers defined by OSPF are as follows: • Internal Router (IR)—An internal router has all of its interfaces within the same area. and adding in the backbone distance to each advertising router. The ABR then forms a picture of the distance to all networks outside of its area by examining the collected advertisements. It is responsible for exchanging summary advertisements with other ABRs. Not-So-Stubby-Areas (NSSA) NSSAs are similar to the existing OSPF stub area configuration option. and then expand into other areas.0. you should start with area 0. • External routes originating from the NSSA can be propagated to other areas. you must create the area first using the following command: create ospf area <areaid> Stub Areas OSPF allows certain areas to be configured as stub areas.0. • Autonomous System Border Router (ASBR)—An ASBR acts as a gateway between OSPF and other routing protocols. The backbone allows summary information to be exchanged between ABRs.0.0. All areas in an autonomous system must be connected to the backbone.0. The CLI command to control the NSSA function is similar to the command used for configuring a stub area. or other autonomous systems. • Area Border Router (ABR)—An ABR has interfaces in multiple areas.0) Any OSPF network that contains more than one area is required to have an area configured as area 0. A stub area is connected to only one other area. If you want to configure the VLAN to be part of a different OSPF area. Stub areas are used to reduce memory consumption and computation requirements on OSPF routers. External route information is not distributed into stub areas. as follows: config ospf area <area_id> nssa {summary | nosummary} stub-default-cost <cost> {translate} 198 Summit 200 Series Switch Installation and User Guide . Every ABR hears the area summaries from all other ABRs. The area that connects to a stub area can be the backbone area.0. You can create a maximum of 7 non-zero areas. including the backbone area.

Virtual Links In the situation when a new area is introduced that does not have a direct physical attachment to the backbone. When configuring an OSPF area as an NSSA. Doing so inhibits correct operation of the election algorithm. If translate is not used on any NSSA border router in a NSSA. Figure 34 illustrates a virtual link. where translation is to be enforced. the connection using ABR2 provides redundancy so that the discontiguous area can continue to communicate with the backbone using the virtual link. one of the ABRs for that NSSA is elected to perform translation (as indicated in the NSSA specification). The option should not be used on NSSA internal routers. a virtual link is used. with one ABR connected to the backbone. in Figure 35. if the connection between ABR1 and the backbone fails. • NSSA. the translate should only be used on NSSA border routers.Overview of OSPF The translate option determines whether type 7 LSAs are translated into type 5 LSAs. A virtual link provides a logical path between the ABR of the disconnected area and the ABR of the normal area that connects to the backbone. Figure 34: Virtual link using Area 1 as a transit area Virtual link ABR ABR Area 2 Area 1 Area 0 EW_016 Virtual links are also used to repair a discontiguous backbone area. A virtual link must be established between two ABRs that have a common area. External routes can be distributed into normal areas. Summit 200 Series Switch Installation and User Guide 199 . • Stub area. Normal Area A normal area is an area that is not: • Area 0. NOTE Virtual links can not be configured through a stub or NSSA area. For example. Virtual links can be configured through normal areas.

An OSPF point-to-point link supports only zero to two OSPF routers and does not elect a DR or BDR. PPP is an example of a point-to-point link. OSPF will fail to synchronize if the neighbor is not configured. If there is a mismatch. Synchronizes faster than a broadcast link because routers do not elect a DR or BDR.Interior Gateway Routing Protocols Figure 35: Virtual link providing redundancy Virtual link Area 2 ABR 2 ABR 1 Area 1 Area 0 Area 3 EW_017 Point-to-Point Support You can manually configure the OSPF link type for a VLAN.

Disables the advertisement of a default route. Disables poison reverse. Disables split horizon. Disables triggered updates. Resets all RIP parameters to match the default VLAN. Does not change the enable/disable state of the RIP settings. If no VLAN is specified, all VLANs are reset.

Configuring OSPF
Each switch that is configured to run OSPF must have a unique router ID. It is recommended that you manually set the router ID of the switches participating in OSPF, instead of having the switch automatically choose its router ID based on the highest interface IP address. Not performing this configuration in larger, dynamic environments could result in an older link state database remaining in use.

without requiring a reboot of the switch. If your CLI connection is through a Telnet connection (and not the console port). which generates a complete switch configuration in an ASCII format. Downloading an Incremental Configuration A partial or incremental change to the switch configuration may be accomplished by downloaded ASCII files that contain CLI commands. When the switch completes booting. You typically use this type of download in conjunction with the upload config command. it treats the downloaded configuration file as a script of CLI commands. but the command executes normally. As part of the complete configuration download. You could use this feature to update the configuration of the switch regularly from a centrally administered TFTP server. Three types of configuration scenarios that can be downloaded: • Complete configuration • Incremental configuration • Scheduled incremental configuration Downloading a Complete Configuration Downloading a complete configuration replicates or restores the entire configuration to the switch. To download an incremental configuration. The downloaded configuration file is stored in current switch memory during the rebooting process. use the following command: download configuration every <hour (0-23)> 234 Summit 200 Series Switch Installation and User Guide . you are prompted to reboot the switch. use the following command: download configuration [<hostname> | <ipaddress>] <filename> {incremental} Scheduled Incremental Configuration Download You can schedule the switch to download a partial or incremental configuration on a regular basis. and automatically executes the commands. and take effect at the time of the download. To download a complete configuration. As part of the scheduled incremental download. These commands are interpreted as a script of CLI commands. the switch is automatically rebooted. use the following command: config download server [primary | secondary] [<hostname> | <ipaddress>] <filename> To enable scheduled incremental downloads. To configure the primary and/or secondary TFTP server and filename. your connection is terminated when the switch reboots. use the following command: download configuration [<hostname> | <ipaddress>] <filename> After the ASCII configuration is downloaded by way of TFTP.Software Upgrade and Boot Options Using TFTP to Download the Configuration You can download ASCII files that contain CLI commands to the switch to modify the switch configuration. and is not retained if the switch has a power failure. you can optionally configuration a backup TFTP server.

Upgrading and Accessing BootROM

To display scheduled download information, use the following command:
show switch

To cancel scheduled incremental downloads, use the following command:
download configuration cancel

Remember to Save
Regardless of which download option is used, configurations are downloaded into switch runtime memory, only. The configuration is saved only when the save command is issued, or if the configuration file, itself, contains the save command. If the configuration currently running in the switch does not match the configuration that the switch used when it originally booted, an asterisk (*) appears before the command line prompt when using the CLI.

Upgrading and Accessing BootROM
The BootROM of the switch initializes certain important switch variables during the boot process. If necessary, BootROM can be upgraded, after the switch has booted, using TFTP. In the event the switch does not boot properly, some boot option functions can be accessed through a special BootROM menu.

Upgrading BootROM
Upgrading BootROM is done using TFTP (from the CLI), after the switch has booted. Upgrade the BootROM only when asked to do so by an Extreme Networks technical representative. To upgrade the BootROM, use the following command:
download bootrom [<hostname> | <ipaddress>] <filename>]

Accessing the BootROM menu
Interaction with the BootROM menu is only required under special circumstances, and should be done only under the direction of Extreme Networks Customer Support. The necessity of using these functions implies a non-standard problem which requires the assistance of Extreme Networks Customer Support. To access the BootROM menu, follow these steps: 1 Attach a serial cable to the console port of the switch. 2 Attach the other end of the serial cable to a properly configured terminal or terminal emulator, power cycle the switch while depressing the spacebar on the keyboard of the terminal. As soon as you see the BootROM-> prompt, release the spacebar. You can see a simple help menu by pressing h. Options in the menu include — Selecting the image to boot from — Booting to factory default configuration

Software Upgrade and Boot Options

For example, to change the image that the switch boots from in flash memory, press 1 for the image stored in primary or 2 for the image stored in secondary. Then, press the f key to boot from newly selected on-board flash memory. To boot to factory default configuration, press the d key for default and the f key to boot from the configured on-board flash.

Boot Option Commands
Table 69 lists the CLI commands associated with switch boot options. Table 69: Boot Option Commands
Command config download server [primary | secondary] [<hostname> | <ipaddress>] <filename> Description Configures the TFTP server(s) used by a scheduled incremental configuration download.

download bootrom [<hostname> | <ipaddress>] Downloads a BOOT ROM image from a TFTP <filename> server. The downloaded image replaces the BOOT ROM in the onboard FLASH memory.

NOTE If this command does not complete successfully, it could prevent the switch from booting.
download configuration [<hostname> | <ipaddress>] <filename> {incremental} download configuration cancel download configuration every <hour> Downloads a complete configuration. Use the incremental keyword to specify an incremental configuration download. Cancels a previously scheduled configuration download. Schedules a configuration download. Specify the hour using a 24-hour clock, where the range is 0 to 23. Downloads a new image from a TFTP server over the network. If no parameters are specified, the image is saved to the current image. Reboots the switch at the date and time specified. If you do not specify a reboot time, the reboot happens immediately following the command, and any previously scheduled reboots are cancelled. To cancel a previously scheduled reboot, use the cancel option. Saves the current configuration to nonvolatile storage. You can specify the primary or secondary configuration area. If not specified, the configuration is saved to the primary configuration area. Displays the current configuration to the terminal. You can then capture the output and store it as a file.

If you encounter problems when using the switch, this appendix might be helpful. If you have a problem not listed here or in the release notes, contact your local technical support representative.

LEDs
Power LED does not light: Check that the power cable is firmly connected to the device and to the supply outlet. On powering-up, the MGMT LED lights amber: The device has failed its Power On Self Test (POST) and you should contact your supplier for advice. A link is connected, but the Port Status LED does not light: Check that: • All connections are secure. • Cables are free from damage. • The devices at both ends of the link are powered-up. • Both ends of the Gigabit link are set to the same autonegotiation state. Both sides of the Gigabit link must be enabled or disabled. It the two are different, typically the side with autonegotiation disabled will have the link LED lit, and the side with autonegotiation enabled will not be lit. The default configuration for a Gigabit port is autonegotiation enabled. This can be verified by entering the following command:
show port config

Switch does not power up: All products manufactured by Extreme Networks use digital power supplies with surge protection. In the event of a power surge, the protection circuits shut down the power supply. To reset, unplug the switch for 1 minute, plug it back in, and attempt to power up the switch. If this does not work, try using a different power source (different power strip/outlet) and power cord.

You should manually delete the routes if no VLAN IP address is capable of using them. contact your supplier. another user having administrator access level can log in and initialize the device. the Extreme switch links at the correct speed. The Extreme switch 10/100 physical interface uses a method called parallel detection to bring up the link. delete your user name. This is NOT a problem with the Extreme switch. but in half duplex mode.Using the Command-Line Interface Permanent entries remain in the FDB: If you have made a permanent entry in the FDB (which requires you to specify the VLAN to which it belongs and then delete the VLAN). NOTE A mismatch of duplex mode between the Extreme switch and another network device will cause poor network performance. and not the duplex mode. This is a CAT5 cable that has pins 1 and 2 on one end connected to pins 3 and 6 on the other end. Excessive RX CRC errors: When a device that has auto-negotiation disabled is connected to an Extreme switch that has auto-negotiation enabled. Default and Static Routes: If you have defined static or default routes. with a new password. parallel detection on the Extreme switch is only able to sense 10 Mbps versus 100 Mbps speed. you must manually delete the entry from the FDB if you want to remove it. The only way to establish a full duplex link is to either force it at both sides. This is characteristic of a duplex mismatch between devices. This will return all configuration information (including passwords) to the initial values. Summit 200 Series Switch Installation and User Guide 235 . Because the other network device is not participating in auto-negotiation (and does not advertise its capabilities). the switch establishes the link in half duplex mode using the correct speed. You forget your password and cannot log in: If you are not an administrator. or run auto-negotiation on both sides (using full duplex as an advertised capability. In the case where no one knows a password for an administrator level user. Viewing statistics using the show port rx command on the Extreme switch may display a constant increment of CRC errors.

IP Addresses and default routes: The system can have an IP address for each configured VLAN. and vice-versa. All gigabit fiber cables are of the cross-over type. These ports need to be set to auto off (using the command config port <port #> auto off) if you are connecting it to devices that do not support auto-negotiation. 236 Summit 200 Series Switch Installation and User Guide . The system first tries the default route with the lowest cost metric. VLANs. 1000BASE-SX does not work with single-mode fiber (SMF). you must use quotation marks whenever referring to the VLAN name. Only one VLAN using untagged traffic can be configured on a single physical port. It is necessary to have an IP address associated with a VLAN if you intend to manage (Telnet. VLAN configuration can be verified by using the following command: show vlan <name> The solution for this error is to remove port 1 from the VLAN currently using untagged traffic on the port. They cannot contain whitespaces and cannot start with a numeric value unless you use quotation marks around the name. If this were the “default” VLAN. Ensure that you are using multi-mode fiber (MMF) when using a 1000BASE-SX Mini-GBIC. The Extreme switch has auto-negotiation set to on by default for gigabit ports.Troubleshooting No link light on Gigabit fiber port: Check to ensure that the transmit fiber goes to the receive fiber side of the other device. SNMP. You can also configure multiple default routes for the system.

Debug Tracing STP You have connected an endstation directly to the switch and the endstation fails to boot correctly: The switch has STP enabled. Contacting Extreme Technical Support If you have a network issue that you are unable to resolve.com/extreme/support/techsupport.asp to download software updates (requires a service contract) and documentation. Debug Tracing ExtremeWare includes a debug-tracing facility for the switch. Specify that STP has been disabled for that VLAN. Summit 200 Series Switch Installation and User Guide 237 . contact Extreme Networks technical support. Extreme Networks maintains several Technical Assistance Centers (TACs) around the world to answer networking questions and resolve network problems. or turn off STP for the switch ports of the endstation and devices to which it is attempting to connect.com You can also visit the support website at: • http://www.
