Each supervisor also includes two Gigabit Ethernet ports. along with the cabling. There are also 14 Catalyst 3548s. each of which contains 16 Gigabit Ethernet ports. Inc. Physical Topology The following section describes the physical layout of the switches in the network. each of which has 24 Fast Ethernet ports and two Gigabit Ethernet ports.5(3). In addition to the 17 switches in production. The Cat6509 is running IOS v5. each of which has 48 Fast Ethernet ports and two Gigabit Ethernet ports. each of which contains 48 Fast Ethernet ports. there are two spare Cat3524s and one spare Cat3548. There are four 6416 blades (in slots 3 through 6). Network Documentation for FBN 3 Overview This document contains detailed information about the network at the Boulder office of FBN Industries. PC Consulting was contracted to install new LAN switches from Cisco Systems and provide documentation of the new network configuration. Equipment This section describes the new network equipment installed in the FBN network. . There are three Catalyst 3524s. Each supervisor includes a Multi-layer Switch Feature Card 2 (MSFC2) for Layer 3 switching. and some servers also have Gigabit Ethernet interfaces that connect to the Cat6509. and the MSFC2s are running IOS v12. Server Room The server room contains the Cat6509 core switch.1(2)E Desktop Edition. All of the Cat3500s are running IOS v12.2)XU.) There are two 6348 blades (in slots 7 and 8). These are not capable of providing in-line power. PC Consulting. These switches are also capable of providing in-line power to IP telephones. Distribution The closet switches are all Cisco Catalyst 3500-series switches. The servers connect to the Fast Ethernet ports on the Cat6509. (All of the Gigabit Ethernet ports require Gigabit Interface Converter (GBIC) modules for connectivity.0(5. Core The core switch is a Cisco Catalyst 6509 with dual supervisors (in slots 1 and 2).

168. Network Documentation for FBN 4 Floor Closets Each closet contains several Cat3500 switches.0/24 87 1st Floor East PC Consulting. VLANs The FBN network is divided into several VLANs. Inc. and all of the VLANs correspond to a single wiring closet. Network Addressing IP and IPX are the two network protocols in use on the FBN network. . There is also a test VLAN that is not routed to the rest of the network. The following table lists the IP and IPX networks assigned to various part of the FBN network: IP Network IPX Network Location/Purpose 192. one Cat3524  3rd Floor East – two Cat3548s. The following are the VLAN assignments for the closets:  VLAN 86 – 1st Floor West  VLAN 87 – 1st Floor East  VLAN 88 – 2nd Floor West  VLAN 89 – 2nd Floor East  VLAN 91 – 3rd Floor East  VLAN 92 – 3rd Floor West  There are two VLANs used in the server room—VLANs 93 and 94. The closet layouts are as follows:  1st Floor East – two Cat3548s  1st Floor West – one Cat3548.168. which is VLAN 100.87. the fiber connections terminate in the GigabitEthernet0/1 interfaces in the top and bottom switches in each closet. which use short-distance copper cabling as a transport. In each closet. The switches are linked together by connecting each switch to its two nearest neighbors (the switches directly above and below) in the closet. In each closet.86. one Cat3524  2nd Floor East – two Cat3548s  2nd Floor West – three Cat3548s. one Cat3524  3rd Floor West – four Cat3548s There are two active connections from the core switch to each closet. Logical Topology This section outlines the logical topology (Layer 3) of the FBN network. rather than fiber.0/24 86 1st Floor West 192. inter-switch connections are made through GigaStack GBICs.

Each interface blade in the Cat6509 is independent.88. As a general rule.0/24 1003 Server Room 192. The list of switches in Appendix A includes the IP address of each switch. and the other remains in standby mode. Router 1 (the primary HSRP router) uses the IP address . The interruption to the network traffic should be less than one second. The IP address for each switch is assigned from the VLAN for the closet in which it resides.168.0/24 91 3rd Floor East 192. all users should be able to access the network if any one cable fails or is removed. The virtual router IP address is .100. which act as the default gateway on each subnet. which share the power load when both are on. The trunks to the closet switches are redundant through use of the GigaStack modules that connect all of the switches in a closet together.3. Only one supervisor is active at any time. Technical Considerations for Switches The following considerations were taken into account when creating the switch configurations. Hot Standby Router Protocol (HSRP) is enabled on VLANs for failover between the two MSFC2s in the Cat6509. Under normal operating conditions.0/24 92 3rd Floor West 192.2 for each VLAN.93. and Router 2 (the secondary router) uses . They are configured such that all changes to the active supervisor configuration will also update the standby supervisor. Network Documentation for FBN 5 192.168.89.168.168. so failure of one blade should not affect any others.168. .92.168.1 for each of the VLANs. Inc.91. Should the active supervisor fail. the standby supervisor immediately takes over the switching functions of the Cat6509.94. The Cat6509 also contains dual power supplies. and the other half of the switches use the other PC Consulting.0/24 N/A Test VLAN – NOT ROUTED Each switch has an IP address assigned for management purposes. If one of the power supplies fails or is removed. Redundancy The dual supervisors in the Cat6509 provide redundancy in the core switch. The only critical part of the Cat6509 that is not redundant is the backplane. the other power supply can support all of the power load. Technical Considerations This section contains information about the technical considerations that influenced the configurations of the switches and the routers.0/24 1002 Server Room 192.0/24 89 2nd Floor East 192.168. With the two fiber connections back to the core from two different switches in the closet.0/24 88 2nd Floor West 192. half of the switches in a closet use one fiber link.

which required about 45 seconds in testing. the two fiber connections from each closet connect to two independent blades. To prevent the failure of any one blade in the Cat6509 from isolating a group of users. STP allows switches to calculate the structure of the network and disable ports as needed to eliminate loops. the switches may PC Consulting. STP Portfast Mode By default. and the NetWare Client has tried to identify a logon server. Network Documentation for FBN 6 link. in which there are three switches. rather than the top switch. Should either fiber link fail. so it becomes active immediately. In order to optimize traffic and eliminate guesswork. This failover requires a recalculation of the Spanning Tree Protocol. every port connected to an end station should be put into portfast mode. Because the Cat6509 is the root bridge. Spanning Tree Protocol The Spanning Tree Protocol (STP) is used by switches to detect and disable physical loops in the Layer 2 network. If a loop is introduced on a portfast port. that switch has been explicitly configured to prefer the fiber link through the bottom switch in the closet. STP permits Layer 2 networks to be built with loops while preventing the negative impact loops normally have. Therefore. If these things happen before a port is in the STP forwarding state. Therefore. In that time. the switches automatically change over to the other fiber connection out of the closet. Inc. the port does not run STP. Explicitly choosing a root bridge is important to ensure optimal path selection by STP. Only if there is a problem with that connection should a switch failover to the other fiber connection in the closet. each closet switch prefers the most direct route to it. On the FBN network. A switch can be given preference in the root selection process by configuring it with a priority lower than that of all other switches on the network. The only exception to this rule is in the 3rd Floor East closet. Selection of an appropriate root bridge will also minimize the impact of network failures on other parts of the network. usually DHCP has already attempted to lease an IP address. This gives the middle switch in that closet two connections of equal cost to the core. (Every VLAN has its own instance of STP. In portfast mode. network services can fail. STP is enabled on all switch ports. the switch must cycle through listening and learning states before it can forward packets on those ports. The root bridge is the reference point for every other switch on the network to calculate STP. when the network is stable. they are desirable for their fault tolerance capabilities. Although loops are detrimental to Layer 2 networks. This results in at least a 30-second delay in the station receiving any traffic. The most important switch on any network is the STP root bridge. . the Cat6509 is configured to be the root bridge on all VLANs.) The priority configured on the Cat6509 is 8192. It is important to note that connecting switches via ports that are in portfast mode can be detrimental to the network. When a port becomes active. every Cat3500 should use the shortest path to reach the Cat6509.768. while the default for the other switches is 32.

They use 802. all switch ports are access ports. Inc. Therefore. Nontrunk ports (such as those that connect to servers) should be configured with trunking explicitly off. VLAN 1 is not used for any ports in the FBN production network. which is an open standard. the default trunking configuration is to auto-negotiate. Trunk Creation By default.1q trunking protocol only tag frames that are not in the native VLAN of the port. They do need trunking explicitly configured on trunk ports. make sure the native VLAN is set to VLAN 1.1q encapsulation for trunking. PC Consulting. every port on a switch is in VLAN 1. For example. For ease of administration. this has not been changed on the trunk ports on the FBN network. which means they belong to only one VLAN. Ports that are to be trunk ports should all be explicitly configured as well. it is important that two switches that share a trunk are configured with the same native VLAN on directly connected interfaces. so they require no configuration changes on their nontrunk ports. a switch includes VLAN information along with the frames that are sent from that port. Cat3500 switches cannot auto-negotiate trunking. . When configured as a trunk. the Gigabit Ethernet ports in blades 3 and 4 are included in STP. The only ports not assigned to VLANs are trunk ports (explained next). This allows VLANs to exist across multiple switches. so all switch ports must be assigned to other VLANs. but the ports in blade 6 are in portfast mode. as they are reserved for servers with Gigabit Ethernet Connections. All of the Gigabit Ethernet ports on all of the Cat3500s are included in STP (they are not in portfast mode). This is done for every host port on the closet switches and the core switch. making them activate more quickly. However. Connections between switches can be configured as access ports or trunk ports. Generally this is the correct mode for all ports connecting to hosts. This makes the ports become active faster when a host boots. All inter-switch connections on the FBN network are configured as trunks. Whenever creating a trunk port. the network will likely suffer a debilitating broadcast storm. On the Cat6509. If the loop is not disabled. This change is configured manually on each switch.1q trunk is in VLAN 1. Port VLAN Assignment By default. However. All of the Fast Ethernet ports on all of the switches are set to portfast mode. On the Cat6509. if an 802. frames for every other VLAN are tagged with the appropriate identifying information. then all frames for VLAN 1 sent on that port are not tagged. Network Documentation for FBN 7 not detect it and respond accordingly. Native VLANs on Trunks Trunks using the 802. The default native VLAN for all ports is VLAN 1. it is important to note this setting for future changes to the network.

This behavior is inefficient and defeats some of the purpose of creating VLANs. The one exception to pruning is VLAN 1. EtherChannel configuration EtherChannels allow two adjacent Cisco switches to exchange traffic over more than one physical interface. that traffic would cross every trunk port on the network. it requests traffic for VLAN 91. VTP Pruning When using trunks to carry traffic for multiple VLANs between switches. . and every Cat3500 switch is a VTP client. This way. since the ports are running in full duplex mode). This prevents delays in the time it takes the ports to become active. If it has no ports in VLAN 92. but it is a good idea to limit the exposure to VLAN changes. PC Consulting. so they require no configuration changes to disable EtherChannels. so this functionality is explicitly turned off on all ports. every VLAN would have to be configured on every switch. Inc. the Cat6509 switch is the only VTP server. all ports on a Cat6509 switch are set to auto-negotiate EtherChannels. Technical Considerations for Routers The following considerations were taken into account when creating the router configurations. only required traffic crosses the trunk. it requests that VLAN 92 be pruned by the upstream switch. For example. On the FBN network. VTP carries VLAN information across trunking interfaces of adjacent switches. the default behavior is to send traffic from every VLAN across every trunk. Therefore. they can be bonded to provide twice the bandwidth (effectively 4 Gbps. There can be an unlimited number of VTP servers on a network. Network Documentation for FBN 8 VTP Switches can share VLAN information with each other using the VLAN Trunking Protocol (VTP). If a switch has ports in VLAN 91. VLAN information can be updated only on VTP servers. This saves time and effort. If there is a broadcast storm on any one subnet. Cat3500 switches cannot auto-negotiate EtherChannels. VTP transfers useful information about each VLAN. VTP pruning allows the switches to communicate which VLANs they need to receive traffic for. using significant bandwidth. By default. if two Gigabit Ethernet ports on one switch connect to two Gigabit Ethernet ports on another switch. VLAN 1 is not used for any production subnets at FBN. thereby increasing the bandwidth available between the switches. However. including its name. all VLANs must be created on the Cat6509 before any ports on any switch can be made members of the VLANs. VLAN 1 is used for control purposes and can never be pruned. so there should be no traffic on it. The FBN network is not using EtherChannels. because without VTP. which makes troubleshooting easier.

The configuration of the helper address is required on the VLAN interface for every other VLAN. For information about the IP addresses in use. If a packet arrives for which the router has no matching route. additional packets with the same header information will not be processed by the MSFC2. However. for non-routing IP hosts on the networks. Helper Addresses In order to use DHCP across IP subnets. having two routers poses no problem. classless routing is preferable. see the “Network Addressing” section earlier in this document. as traffic destined for other VLANs simply has two possible routers to go through.) Having both routers active offers the advantage that the routers and switches can failover independently of each other. If either MSFC2 fails.) In most cases. helper addresses must be configured on the router interfaces attached to subnets that do not have a DHCP server of their own. both MSFC2s are active concurrently. To prevent extra protocol traffic from being forwarded. After a packet is routed the first time two hosts exchange traffic. Classless IP Routing Cisco routers can make routing decisions using two different methods—classful and classless. First. Cisco routers use the Hot Standby Router Protocol (HSRP) to share virtual IP and MAC addresses. If not. When a router is using classful IP routing. its routing decisions are very simple. Cisco routers forward eight protocols to those addresses by default. the unnecessary this is explicitly disabled in the router configurations—only DHCP traffic should be forwarded. it follows a more complicated procedure when making routing decisions. Fast Switching Fast switching allows the 6509 to take advantage of the Layer 3 Switching feature of the IOS. if the classful network has one or more subnet routes. When a router is using classless routing. For IP and IPX. Instead. the router discards the packet rather than forwarding it. and it is the default in the IOS on the FBN MSFC2s. The virtual IP address is configured to be the default gateway on every VLAN. the other router still answers for the virtual IP address. the router checks if any routes match the destination of the packet. On the FBN network. In order to allow these hosts to communicate via their configured default gateway. the router looks for any routes to any part of the classful network to which the packet is destined. . for which only one supervisor is active. the packet is sent via the default route. (This differs from the switching software. Network Documentation for FBN 9 Redundancy In a Cat6509 switch with dual supervisors and dual MSFC2s. DHCP packets need to be forwarded to the DHCP server on VLAN 94. Inc. because they are generally configured with only one default gateway. it will forward the packet via the default route. the PC Consulting. If no such routes are found. (The default depends on the version of IOS on a router. However. this can be a problem. so client machines can still route through their default gateways. When configured with helper addresses.

almost all interfaces have been configured for autosensing speed and duplex. so it can be fast switched. Standards This section describes the standards that have been created for the FBN network. this information can be extremely helpful when troubleshooting. Core Switch Port Speeds and Duplex On the Cat6509 core switch. this setting does not need to be changed for IP. These have been followed in the migration to the new network. and these have been changed manually. but it may result in problems for some hosts. the port name is the name of the server or closet switch to which the port connects. Network Documentation for FBN 10 switching cache can determine which port should receive the frame. This should be done for any other ports that do not function correctly in autosensing mode. the packets cannot receive any special processing from the router IOS. ports can be configured with named. This can be a problem in some environments. Some of the ports currently in use require other settings. PC Consulting. Core Switch Port Names On the Cat6509 core switch.3 encapsulation. but IPX fast switching must be explicitly disabled. The IP traffic at FBN should not require any special processing by the MSFC2. and every effort should be made to ensure that they are followed as the network changes. It is strongly recommended that FBN continue to keep this information updated. Inc. a few ports have been manually configured to a particular speed and duplex. odd-length IPX packets need to be padded to be received by hosts. Closet Switches Port Speeds and Duplex On all Cat3500 closet switches. As necessary. It is important to verify the speed and duplex requirements of every host to be connected to the core switch. For all hosts that will not work at 100Mbps and full duplex. Although port names are not required for proper operation of the switch. all of the Fast Ethernet ports have been configured to operate at 100Mbps and full duplex by default. In most cases. which is the default on Cisco routers. Fast switching speeds the traffic between VLANs. even across VLANs. In the case of Novell networks. . Because fast switching prevents the MSFC2 from processing packets. At FBN. and it is enabled by default. Therefore. the ‘ipx network’ interface configuration command does not need to specify the encapsulation. This can be done in the router. Therefore. the port configurations should be changed manually. all used ports have been configured with descriptive port names that indicate their purpose. IPX Encapsulation The FBN IPX traffic uses 802. This should work fine with most end stations.

The core switch is the only VTP server. one per line. Common Changes This section describes changes that are common to many networks and how they should be handled on the FBN network. you can change the speed and/or duplex of more than one port at a time by specifying a port range with these commands.
