    Layer 3 subinterface (Huawei)

    Technology: Network
    Area: Configuration General

    Sub-interfaces are multiple logical interfaces configured on a main (physical) interface to allow to communicate within subnets on a trunk link. Sub-interfaces can share physical layer parameters of their main interface or be configured with their respective link layer parameters and network layer parameters. Disabling or activating sub-interfaces does not affect the main interface status, but the main interface status change affects the status of sub-interfaces. Sub-interfaces work properly only when their main interface is in Up-state. Associating a sub-interface with a VLAN implements inter-VLAN communication and applies to Dot1q termination and QinQ termination scenarios.

    To enter the System configuration mode run:

    system-view

     

    After System-View enter the subinterface mode:

    interface interface-type interface-number.subinterface-number

     

    To configure the IP address:

    ip address ip-address { mask | mask-length } [ subnet ]

     

    To configure the sub-interface for dot1q VLAN Run:

    dot1q termination vid low-pe-vid [ to high-pe-vid ]
