Configuring a VE Interface

Configuring a VE Interface


You can use VE interfaces when other link layer protocols need to be carried by the Ethernet protocol.


  1. Run system-view

    The system view is displayed.

  2. Run interface virtual-ethernet ve-number

    A VE interface is created and the VE interface view is displayed.

  3. Configure a VE interface based on actual requirements.

    • Configure the VE interface to work in Layer 2 mode.

      Run portswitch

      The working mode of the VE interface is changed from Layer 3 mode to Layer 2 mode.

      By default, a VE interface works in Layer 3 mode.

    • Configure a VE sub-interface.

      You need to create a VE sub-interface when configuring an L2VPN to access to an L3VPN.

      1. Run ve-group ve-group-id { l2-terminate | l3-access }

        A Layer 2 or Layer 3 VE interface is created.

      2. Run quit

        Return to the system view.

      3. Run interface virtual-ethernet ve-number.subnumber

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

Verifying the Configuration

  • Run the display interface virtual-ethernet [ ve-number | main ] command to check the status and statistics of the VE interface.
