Configuring 802.1p Priority-based VLAN Mapping

Procedure

• Configuring VLAN mapping on the inbound interface based on the 802.1p priority
  1. Run:

     system-view

     The system view is displayed.

  2. Run:

     interface interface-type interface-number

     The interface view is displayed.

  3. Run:

     port link-type { hybrid | trunk }

     The port link-type is set.

  4. Run either of the following commands as required:

     • To configure VLAN mapping on the inbound interface based on the 802.1p priority, run port vlan-mapping 8021p 8021p-value map-vlan vlan-id [ remark-8021p 8021p-value2 ].

     • To configure VLAN mapping on the inbound interface based on the VLAN ID and 802.1p priority, run port vlan-mapping vlan vlan-id1 [ to vlan-id2 ] 8021p 8021p-value1 [ to 8021p-value2 ] map-vlan vlan-id3 [ remark-8021p 8021p-value3 ].

     VLAN mapping based on the 802.1p priority is not supported on the SA boards of S series.

• (Optional) Configuring VLAN mapping on the outbound interface based on the 802.1p priority

  If the DiffServ domain is created on the inbound interface and VLAN mapping is configured based on the priority, the internal priority may be different from the 802p.1 priority. You are advised to configure VLAN mapping on the outbound interface based on the 802.1p priority.

  1. Run:

     system-view

     The system view is displayed.

  2. Run:

     diffserv domain ds-domain-name

     The DiffServ domain is created, and the DiffServ domain view is displayed.

  3. Run:

     8021p-outbound service-class color map 8021p-value

     The internal priority of VLAN packets on the outbound interface in the DiffServ domain is mapped to the 802.1p priority.

  4. Run:

     quit

     The DiffServ domain view is quit.

  5. Run:

     interface interface-type interface-number

     The interface view is displayed.

  6. Run:

     trust upstream ds-domain-name

     The DiffServ domain is bound on the interface and the mapping in the DiffServ domain is applied.

     By default, an internal priority remains the same after being mapped to an external priority.
