Entering the Interface View

Entering the Interface View


To configure an interface, enter the interface view first.


  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

    interface-type interface-number specifies the type and number of an interface.


    If the specified interface does not exist, this command creates the interface and displays the interface view.

    • Only the E series, X series, and SC series cards on the S12700 support Ethernet sub-interface configuration. For details about the cards, see Cards in the Hardware Description.

    • Only hybrid and trunk interfaces on the preceding series of cards support Ethernet sub-interface configuration.
    • After you run the undo portswitch command to switch Layer 2 interfaces on the preceding series of cards into Layer 3 interfaces, you can configure Ethernet sub-interfaces on the interfaces.

    • The SA series cards do not support Ethernet sub-interface configuration and cannot forward IP traffic to Ethernet sub-interfaces on other cards.

    • You are advised to add a member interface to an Eth-Trunk and then configure an Eth-Trunk sub-interface. The Eth-Trunk sub-interface can be successfully configured only when the card on which the member interface locates supports Ethernet sub-interface configuration.

    • VLAN termination sub-interfaces cannot be created on a VCMP client.
