Configuring a Dot1q Termination Sub-interface

Configuring a Dot1q Termination Sub-interface


When a VPN connects to an ISP network through a sub-interface, the sub-interface needs to remove VLAN tags of the packets that the VPN has sent to the ISP network. When each packet that CEs send to PEs carries one VLAN tag, the sub-interface terminates the single VLAN tag. This sub-interface is called Dot1q termination sub-interface.


  1. On the PE device, run:


    The system view is displayed.

  2. Run interface interface-type interface-number.subinterface-number

    The view of the sub-interface connecting the PE to the CE is displayed.

  3. Run dot1q termination vid low-pe-vid [ to high-pe-vid ]

    Dot1q termination is configured on the sub-interface.

    • high-pe-vid is supported by only the AR3200-S.

    • You can specify high-pe-vid only after the termination-vid batch enable command is used to enable a sub-interface to batch terminate VLAN tags.

    • The value of high-pe-vid must be greater than or equal to the value of low-pe-vid.

    • When this command is executed on an Eth-Trunk sub-interface, you cannot specify high-pe-vid.
