Chapter 1 VLAN Configuration

Chapter 1 VLAN Configuration
1.1 VLAN Overview
1.1.1 Introduction to VLAN
The virtual local area network (VLAN) technology is developed for switches to control
broadcast operations in LANs.
By creating VLANs in a physical LAN, you can divide the LAN into multiple logical LANs,
each of which has a broadcast domain of its own. Hosts in the same VLAN
communicate with each other as if they are in a LAN. However, hosts in different VLANs
cannot communicate with each other directly. In this way, a broadcast frame is confined
within one VLAN, as shown in Figure 1-1.

Figure 1-1 A VLAN implementation
A VLAN can span across multiple switches, or even routers. This enables hosts in a
VLAN to be dispersed in a more loose way. That is, hosts in a VLAN can belong to
different physical network segments.
VLAN enjoys the following advantages.
z

Broadcasts are confined to VLANs. This decreases bandwidth utilization and
improves network performance.

z

Network security is improved. Packets of different VLANs are isolated during
transmission. That is, hosts in different VLANs cannot communicate with each
other directly. To enable communications between different VLANs, network
devices operating on Layer 3 (such as routers or Layer 3 switches) are needed.

2 VLAN Classification Depending on how VLANs are established.3 Basic VLAN Interface Configuration VLAN interface is a virtual interface in Layer 3 mode. no additional network configuration is required if the host still belongs to the same VLAN.Operation Manual – VLAN H3C S5500-SI Series Ethernet Switches z Chapter 1 VLAN Configuration Configuration workload is reduced. 1-2 .1. 1. Optional Specify the description string of the VLAN description text By default. this command will first create the VLAN. VLAN can be used to group specific hosts. 1. When the physical position of a host changes.2 Basic VLAN Configuration Table 1-1 Basic VLAN configuration To do… Use the command… Enter system view system-view Create VLANs in bulk vlan { vlan-id1 vlan-id2 | all } Remarks — to Optional Required Create a VLAN and enter VLAN view vlan vlan-id If the specified VLAN does not exist. and then enter VLAN view. the description string of a VLAN is its VLAN ID. 1. This chapter will focus on the port-based VLAN. VLANs fall into the following six categories: z Port-based VLAN z MAC-based VLAN z Protocol-based VLAN z IP sub network-based VLAN z Policy-based VLAN z Other VLAN H3C S5500-SI Series Ethernet Switch supports the port-based VLAN. such as “VLAN 0001”. and mainly used in realizing the Layer 3 connectivity between different VLANs.

such as “Vlan-interface1 interface”. Note: Before creating a VLAN interface. Otherwise.1 Introduction of Port-Based VLAN Port-based VLAN is the simplest and most effective VLAN division method. the VLAN interface is up.4.4 Port-Based VLAN Configuration 1. It defines its VLAN members according to the ports of a switch. After a specified port is added into a specified VLAN. you cannot create the VLAN interface successfully. the VLAN interface is down. the port can forward the packets of the specified VLAN. this command will create it first and then enter VLAN interface view. the corresponding VLAN must exist. no IP address is configured for a VLAN interface Optional Specify the description string for the current VLAN interface description text By default. 1. Optional By default. if one or more ports under the VLAN interface are up. Optional Enable Interface the VLAN undo shutdown By default. the description string of a VLAN interface is the name of the VLAN interface. if all the ports under the VLAN interface are down.Operation Manual – VLAN H3C S5500-SI Series Ethernet Switches Chapter 1 VLAN Configuration Table 1-2 Configure a VLAN interface To do… Use the command… Enter system view system-view Remarks — Required Create a VLAN interface and enter VLAN interface view interface vlan-interface vlan-interface-id Configure IP address of VLAN interface ip address ip-address { mask | mask-length } [ sub ] If the specified VLAN interface does not exist. 1-3 .

But you can configure it as needed. it is generally used to connect a switch. for an access port. If you do so.Operation Manual – VLAN H3C S5500-SI Series Ethernet Switches Chapter 1 VLAN Configuration I. refer to Chapter 2 Voice VLAN Configuration. II. The way by which a port processes incoming and outgoing packets depends on the link type and default VLAN configured on it. the link type of the port can be one of the following three types: z Access. A hybrid port can also belong to more than one VLAN and receives/sends the packets of multiple VLANs. Link Type of an Ethernet Port Depending on how a port processes VLAN tags when it forwards packets. For information about the voice VLAN. you cannot configure the voice VLAN as the default VLAN of the ports. the default VLAN of all the ports is VLAN 1. You can configure the default VLAN for them. that is. A trunk port can belong to more than one VLAN and receives/sends the packets of multiple VLANs. An access port belongs to only one VLAN. z A trunk port only allows the packets from the default VLAN to be sent without tags. Note: For ports of a voice VLAN in automatic mode. for a trunk or a hybrid port. By default. its default VLAN configuration remain unchanged. z Both of the trunk port and hybrid port allow multiple VLANs to pass through. The difference between the hybrid port and the trunk port is that: z A hybrid port allows the packets from multiple VLANs to be sent without tags. An access port is generally used to connect a user device. it strips VLAN tags when sending the packets of the VLAN. Refer to the following table for details: 1-4 . In additional. z After you delete the default VLAN of a port through the undo vlan command. you can also configure a default VLAN for the port. its default VLAN restore to VLAN 1. it is used to connect a switch or a user device. z Trunk. z Hybrid. a trunk port or hybrid port can use the presently nonexistent VLAN as the default VLAN. the system will prompt that you cannot perform the configuration. Default VLAN You can configure a VLAN for a port. z The default VLAN of an access port is the VLAN the access port belongs to and cannot be configured.

1-5 . z When the VLAN ID is the same with the default VLAN ID. remove the tag of the packet first and then send the packet. Drop the packet when the VLAN ID is different with the default VLAN ID.Operation Manual – VLAN H3C S5500-SI Series Ethernet Switches Chapter 1 VLAN Configuration Table 1-3 Incoming and outgoing packets Incoming packet Port type If no tag is carried in the packet Outgoing packet If a tag is carried in the packet z Access port z Receive the packet when the VLAN ID (recorded in the tag) is the same with the default VLAN ID.4. or configure it in Ethernet port view/port group view. When the VLAN ID is different with the default VLAN ID but is allowed on the port. Receive the packet when the VLAN ID is different with the default VLAN ID but is allowed on the port. send the packet. You can configure whether or not to carry tags in the outgoing packets of a VLAN (including default VLAN) through the port hybrid vlan command. Drop the packet when the VLAN ID is different with the default ID and is not allowed on the port. z z Trunk port Encapsulate the default VLAN tag to the packet z z Hybrid port Receive the packet when the VLAN ID (recorded in the tag) is the same with the default VLAN ID. Remove the tag and send the packet directly for the VLAN ID is just the default VLAN ID. 1. When the VLAN ID is allowed on the port.2 Configuring an Access Port-Based VLAN You can configure an access port-based VLAN in two ways: configure it in VLAN view. keep the original tag and send the packet.

1. this command will create the VLAN first and then enter VLAN view of the VLAN.3 Configuring a Trunk Port-Based VLAN A trunk port allows multiple VLANs to pass. Note: You must add an access port to an existing VLAN. the following settings are effective on the current port only. all access ports belong to VLAN 1. Required By default.Operation Manual – VLAN H3C S5500-SI Series Ethernet Switches Chapter 1 VLAN Configuration Table 1-4 Configure an access port-based VLAN (in VLAN view) To do… Enter system view Use the command… system-view Remarks — Required Enter VLAN view Add an Ethernet port to a specified VLAN vlan vlan-id If the specified VLAN does not exist. a port is an access port. and you can configure it in Ethernet port view/port group view. the following settings are effective on all ports in the port group Optional Configure a port as an access port port link-type access Add the current access port to a specified VLAN port access vlan vlan-id By default. 1-6 .4. the system adds all ports to VLAN 1. configured in port group view.

Required port interface-list By default.

z The default VLAN ID of the trunk port on the local switch must be the same as that of the trunk port on the peer switch. a trunk port cannot be configured to be a hybrid port directly. you must specify the trunk port as an access port first. the packets of the default VLAN cannot be transmitted correctly from the local end to the peer end. configured in port group view. the link type of a port is access. For example. all trunk ports only allow the packets of VLAN 1 to pass.4 Configuring a Hybrid Port-Based VLAN A hybrid port allows multiple VLANs to pass. Optional Set the default VLAN for the trunk port port trunk vlan-id pvid vlan By default. the default VLAN of the trunk port is VLAN 1 Note: z A trunk port and a hybrid port cannot switch to each other directly but must be configured as an access port first. 1-7 . Required By default. Otherwise. the following settings are effective on all ports in the port group Required Configure a port as a trunk port port link-type trunk Add the current trunk port to specified VLANs port trunk permit vlan { vlan-id-list | all } By default. 1.4. and then specify the access port as a hybrid port.Operation Manual – VLAN H3C S5500-SI Series Ethernet Switches Chapter 1 VLAN Configuration Table 1-6 Configure a trunk port-based VLAN To do… Enter system view Enter Ethernet port view or port group view Use the command… Remarks — system-view Enter Ethernet port view interface interface-type interface-number Enter port group view port-group { manual port-group-name | aggregation agg-id } Use either command Configured in Ethernet port view. the following settings are effective on the current port only. and you can configure it in Ethernet port view/port group view.

The following table shows the five default OUI addresses of a switch. the packets are determined as voice packets and transmitted in voice VLAN. z You can add or delete the default OUI address manually. ensuring the transmission priority of voice data stream and voice quality. you can perform quality of service (QoS)-related configuration for voice data. By adding the ports with voice devices attached to voice VLANs. 2. You can determine which vendor a device belongs to according to the OUI address which forms the first 24 bits of a MAC address.1 Voice VLAN Overview Voice VLANs are VLANs configured specially for voice data stream.1 Automatic and Manual Voice VLAN Modes According to how a port is added to the voice VLAN.1. Table 2-1 Default OUI addresses preset by the switch Number OUI Address Vendor 1 0001-e300-0000 Siemens phone 2 0003-6b00-0000 Cisco phone 3 00d0-1e00-0000 Pingtel phone 4 00e0-7500-0000 Polycom phone 5 00e0-bb00-0000 3com phone Note: z An organizationally unique identifier (OUI) address is a globally unique identifier assigned to a vendor by Institute of Electrical and Electronics Engineers (IEEE). If the source MAC addresses of packets comply with the organizationally unique identifier (OUI) addresses configured by the system. S5500-SI series Ethernet switches determine whether a received packet is a voice packet by checking its source MAC address. the port can work in one of the two voice VLAN modes: automatic and manual. You can configure an OUI address for voice packets or specify to use the default OUI address. 2-1 .Operation Manual – VLAN H3C S5500-SI Series Ethernet Switches Chapter 2 Voice VLAN Configuration Chapter 2 Voice VLAN Configuration 2.

When the administrator adds a port to the voice VLAN. z In manual mode. Access Untagged voice stream Trunk Hybrid 2-2 Not supported. The system then identifies the source MAC address contained in the packets on the port. And the port permits the packets of the default VLAN. The voice VLAN working modes of different ports are independent and different ports can be configured to work in different modes. the port forwards tagged packets in the same manner: forward the tagged packets based on the VLAN IDs contained in them. and decides whether to forward the packets in the voice VLAN. and port types. the administrator adds the IP phone access port directly to the voice VLAN. the adding or deleting of ports is realized by the administrators. The system will remove a port from the voice VLAN if no voice packets are received from it within the aging time. The following table lists the co-relation between voice VLAN modes. the system identifies the source MAC address contained in the untagged packet sent when the IP phone is powered on and matches it against the OUI addresses. In any of the two modes. An aging time can be configured on the device. Supported Automatic mode Hybrid Make sure the default VLAN of the port exists and is in the list of the tagged VLANs whose packets are permitted by the port. the system will automatically add the port into the Voice VLAN and send ACL rules to ensure the packet precedence. Table 2-2 Port modes and voice stream types Port voice VLAN mode Voice stream type Port type Access Supported or not Not supported Supported Trunk Tagged voice stream Make sure the default VLAN of the port exists and is not a voice VLAN. The above two working modes are configured in Ethernet port view.

2) GARP timers GARP sets interval for sending GARP messages by using these four timers: z Hold timer –– When a GARP application entity receives the first registration request. provides a mechanism that allows participants in a GARP application to distribute. this port is regarded a GARP application entity. and LeaveAll. When the timer expires. I. z Leave timer –– Starts upon receipt of a Leave message. Leave messages guarantee attribute reregistration and deregistration. z Join timer –– A GARP application entity can send a Join message twice to ensure the message can be transmitted to other entities. the entity sends all these requests in one Join message. This can thus help you save bandwidth.1. z Join to announce the willingness to register attributes with other participants. such as the VLAN or multicast address attribute. the GARP application entity removes attribute information as requested.1 Introduction to GARP The generic attribute registration protocol (GARP). Leave. propagate. all attribute information that needs registration propagates to all GARP participants throughout a bridged LAN. and register with other participants in a bridged LAN the attributes specific to the GARP application. One example is GVRP. The sending interval is set on the join timer. When a GARP application entity is present on a port on your device.Operation Manual – VLAN H3C S5500-SI Series Ethernet Switches Chapter 3 GVRP Configuration Chapter 3 GVRP Configuration 3.1 Introduction to GARP 3. it starts a hold timer and collects succeeding requests. A LeaveAll message is sent upon expiration of a LeaveAll timer which starts upon the startup of a GARP application entity. GARP-compliant application entities are called GARP applications. GARP participants exchange information with each other through the following three types of messages: Join. Through message exchange. GARP messages and timers 1) GARP messages Generally. When this timer expires. z Leave to announce the willingness to deregister with other participants. Together with Join messages. 3-1 . z LeaveAll to deregister all attributes.

the leaveall timer is set in system view and takes effect globally. Then. a leaveall timer starts again. should a GARP PDU be delivered. In GARP. a device can identify to which GVRP application. Figure 3-1 GARP message format 3-2 . III. based on received declarations or withdrawals handles attributes of other participants. Based on this address. a GARP participant registers or deregisters its attributes with other participants by making or withdrawing declarations of attributes and at the same time. II. GARP application entities send protocol data units (PDU) with a particular multicast MAC address as destination. GARP message format The following figure illustrates the GARP message format. GVRP for example.Operation Manual – VLAN H3C S5500-SI Series Ethernet Switches z Chapter 3 GVRP Configuration Leaveall timer –– Starts when a GARP application entity starts. When this timer expires. such as GVRP. whichever is smaller. Operating mechanism of GARP The GARP mechanism allows the configuration of a GARP participant to propagate throughout a LAN quickly. z A GARP application entity may send LeaveAll messages at the interval set by its LeaveAll timer or the leaveall timer of another GARP application entity on the network. Note: z The settings of GARP timers apply to all GARP applications. z Unlike other three timers which are set on a port basis. running on a LAN. the entity sends a LeaveAll message so that other entities can re-register its attribute information.

The VLAN registration information propagated by GVRP includes both manually configured local static entries and dynamic entries from other devices. Attribute Value is omitted –– Attribute Length Number of octets occupied by an attribute. If the Attribute Event is LeaveAll.2 Introduction to GVRP GVRP enables a device to propagate local VLAN registration information to other participant devices and dynamically update the VLAN registration information from other devices to its local database. 3-3 . inclusive of the attribute length field 2 to 255 in bytes 0: LeaveAll 1: JoinEmpty Attribute Event Event described by the attribute 2: JoinIn 3: LeaveEmpty 4: LeaveIn 5: Empty Attribute Value Attribute value VLAN ID for GVRP End Mark Indicates the end of PDU of GARP –– 3. an Attribute Event.

It thus ensures that all GVRP participants on a bridged LAN maintain the same VLAN registration information. indicating the VLAN ID attribute Attribute List Consists of one or multiple attributes –– Attribute Consists of an Attribute Length. and to propagate both dynamic and static VLAN information. GVRP provides the following three registration types on a port: z Normal –– Enables a port to dynamically register and deregister VLANs. each containing an attribute type and an attribute list –– Attribute Type Defined by the concerned GARP application 0x01 for GVRP. and an Attribute Value.1.Operation Manual – VLAN H3C S5500-SI Series Ethernet Switches Chapter 3 GVRP Configuration The following table describes the GARP message fields.
