How Do I Create a Sub-interface?

How Do I Create a Sub-interface?


  • # Configure an Ethernet sub-interface. (The physical interface must be switched to Layer 3 mode.)

    <Huawei> system-view
    [Huawei] interface GigabitEthernet 0/0/0.1
    [Huawei-GigabitEthernet0/0/0.1] ip address 24     //Configure an IP address for the Ethernet sub-interface.
  • # Configure an Eth-Trunk sub-interface.

    <Huawei> system-view
    [Huawei] interface Eth-Trunk 1     //Create a Layer 2 Eth-Trunk.
    [Huawei-Eth-Trunk1] undo portswitch    //Configure the Eth-Trunk to work in Layer 3 mode.
    [Huawei-Eth-Trunk1] quit
    [Huawei] interface Eth-Trunk 1.1       //Create a Layer 3 Eth-Trunk sub-interface.

More Information

Layer 2 sub-interfaces are mainly used on a VXLAN network. On the VXLAN network, you need to configure VXLAN service access points on a VXLAN network edge node. You can configure Layer 2 sub-interfaces to configure VXLAN service access points. After configuring Layer 2 sub-interfaces, add them to a bridge domain (BD) so that service packets are forwarded in the BD.
