Binding a User VLAN to a Sub-interface

To restrict broadcast packets on a LAN and enhance LAN security or create virtual groups, configure VLANs. VLANs apply only to Ethernet sub-interfaces.

Context

If users access the network through a sub-interface, you must bind a user VLAN to the sub-interface.

You can bind a user VLAN to a sub-interface or configure QinQ on a sub-interface. When binding a user VLAN to a sub-interface, you need the following parameters:

  • Sub-interface number
  • VLAN ID
  • QinQ ID
  • On each interface, you can set user-vlan any-other only on one sub-interface. On one sub-interface, user-vlan any-other cannot be set together with user-vlan start-vlan or user-vlan qinq.
  • The user-vlan command cannot be configured on a sub-interface of a Layer 2 interface.
  • If dot1q termination, QinQ termination, QinQ stacking, or vlan-type dot1q has been configured on a sub-interface, the user-vlan command cannot be configured on this sub-interface.
  • Different sub-interfaces cannot be configured with user VLANs with the same VLAN ID.

Procedure

  1. Run system-view

    The system view is displayed.

  2. (Optional) Run set vlan-statistics subinterface enable

    PPPoE statistics collection is enabled on QinQ interfaces.

  3. Run interface interface-type interface-number. subinterface-number

    A sub-interface is created and the sub-interface view is displayed.

  4. Run user-vlan { start-vlan-id [ end-vlan-id ] | cevlan } qinq { start-pe-vlan [ end-pe-vlan ] | pevlan }

    A user VLAN is bound to the sub-interface.

  5. Run commit

    The configuration is committed.
