Creating an Eth-Trunk Sub-interface

Creating an Eth-Trunk Sub-interface

Sub-interfaces can be configured on a Layer 3 Eth-Trunk. When Layer 3 devices connect to Layer 2 devices in different VLANs through the Layer 3 Eth-Trunk, sub-interfaces must be configured on the Eth-Trunk to identify packets from different VLANs and to enable users in different VLANs to communicate with each other.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface eth-trunk trunk-id

    An Eth-Trunk is created and the Eth-Trunk interface view is displayed.

  3. Run undo portswitch

    A Layer 3 Eth-Trunk is configured.

  4. Run quit

    The system view is displayed.

  5. Run interface eth-trunk trunk-id.subnumber

    An Eth-Trunk sub-interface is created.

    subnumber specifies the number of a sub-interface. The value ranges from 1 to 4096.

  6. Run ip address ip-address { mask | mask-length } [ sub ]

    An IP address is configured for the sub-interface.

    When configuring multiple IP addresses for an Eth-Trunk sub-interface, use the sub keyword to indicate the IP addresses configured after the first one.
