Creating an Eth-Trunk

Creating an Eth-Trunk

Context

Eth-Trunks increase bandwidth and improve transmission reliability. You can configure Layer 2 and Layer 3 Eth-Trunks based on network applications.

Procedure

  • Create a Layer 2 Eth-Trunk.
    1. Run:

      system-view

      The system view is displayed.

    2. Run:

      interface eth-trunk trunk-id

      A Layer 2 Eth-Trunk is created.

      By default, no Eth-Trunk is created.

  • Create a Layer 3 Eth-Trunk.
    1. Run:

      system-view

      The system view is displayed.

    2. Run:

      interface eth-trunk trunk-id

      By default, no Eth-Trunk is created.

    3. Run:

      undo portswitch

      The Eth-Trunk is configured to work in Layer 3 mode.

      By default, the Eth-Trunk works in Layer 2 mode.

    4. Run:

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

      An IP address is configured for the Layer 3 Eth-Trunk.

      By default, no IP address is configured for the Layer 3 Eth-Trunk.

    5. (Optional) Run:

      mac-address mac-address

      A MAC address is configured for the Layer 3 Eth-Trunk.

      By default, an Eth-Trunk uses the system MAC address. When the MAC address of the Eth-Trunk and the MAC address of another interface overlap and a MAC address conflict occurs, run this command to configure a MAC address for the Layer 3 Eth-Trunk.

    6. (Optional) Run:

      mtu mtu

      The maximum transmission unit (MTU) of the Eth-Trunk is set.

      The default MTU of an interface is 1500 bytes.

      • The mtu command cannot be used on Layer 2 Eth-Trunks.

      • Directly connected interfaces must use the same MTU. If you change the MTU of a local interface, you must use the mtu command to change the MTU of the remote interface to be the same value; otherwise, services may be interrupted.
