Protocol-based VLAN Assignment

Procedure

1. Run system-view

   The system view is displayed.

2. (Optional) Run vlan assign global { vlan-id1 [ to vlan-id2 ] } &<1-5>

   VLANs that can be globally assigned are specified.

   After VLANs are assigned, the VLANs created using the vlan vlan-id command must be within the assignable VLAN range.

3. (Optional) Run vlan reserved vlan-id

   A reserved VLAN is configured.

   By default, the reserved VLAN ID ranges from 4064 to 4094. After vlan-id is specified, the VLAN specified by vlan-id to the VLAN specified by vlan-id plus 30 are configured as reserved VLANs.

   CE12800E that has the ED-E/EG-E/EGA-E series cards installed does not support this step.

4. Run vlan vlan-id

   A VLAN is created, and the VLAN view is displayed. If the specified VLAN has been created, the VLAN view is directly displayed.

   The VLAN ID ranges from 1 to 4094 (excluding reserved VLANs). If VLANs need to be created in batches, run the vlan batch { vlan-id1 [ to vlan-id2 ] } &<1-10> command to create VLANs in batches, and then run the vlan vlan-id command to enter the view of a specified VLAN.

   If VLANs are created in a batch, you are advised to create at most 400 VLANs at one time.

   If a device is configured with multiple VLANs, configuring names for these VLANs is recommended:

   Run the name vlan-name command in the VLAN view. After a VLAN name is configured, you can run the vlan vlan-name vlan-name command in the system view to enter the corresponding VLAN view.

   Manually configuring and maintaining VLANs is challenging on a large Layer 2 network. Configuration inconsistency may occur. To improve maintenance efficiency and simplify configuration, run the vlan range { vlan-id1 [ to vlan-id2 ] } &<1-10> command to create a temporary VLAN range and configure services in the VLAN range view. Services are then delivered in batches to all the VLANs in the VLAN range.

5. Run protocol-vlan [ protocol-index ] { at | ipv4 | ipv6 | ipx { ethernetii | llc | raw | snap } | mode { ethernetii-etype etype-id1 | llc dsap dsap-id ssap ssap-id | snap-etype etype-id2 } }

   Protocols are associated with VLANs and a protocol profile is specified.

   • protocol-index specifies the index of a protocol profile.

     A protocol profile depends on protocol types and encapsulation formats, and a VLAN associated with a protocol can be defined in a protocol profile.

   • When specifying the source and destination service access points, pay attention to the following points:

     • dsap-id and ssap-id cannot be both set to 0xaa.

     • dsap-id and ssap-id cannot be both set to 0xe0. 0xe0 indicates llc, encapsulation format of IPX packets.

     • dsap-id and ssap-id cannot be both set to 0xff. 0xff indicates raw, encapsulation format of IPX packets.

6. Run quit

   The system view is displayed.

7. Configure attributes for the Ethernet interface.

   1. Run interface interface-type interface-number

      The view of the interface that allows the protocol-based VLAN is displayed.

   2. Run port link-type hybrid

      The interface is configured as the hybrid interface.

      Protocol-based VLAN assignment can only be configured on hybrid interfaces.

   3. Run port hybrid untagged vlan { { vlan-id1 [ to vlan-id2 ] } &<1-10> | all }

      The hybrid interface is configured to allow the protocol-based VLAN.

8. Run protocol-vlan vlan vlan-id { all | protocol-index1 [ to protocol-index2 ] }

   The interface is associated with a protocol-based VLAN.

   • vlan-id must be the ID of a protocol-based VLAN.

9. Run commit

   The configuration is committed.
