Creating an E-Trunk and Setting the E-Trunk Priority

Creating an E-Trunk and Setting the E-Trunk Priority


The E-Trunk priority determines whether an E-Trunk member device is the master or backup device.


  1. Run system-view

    The system view is displayed.

  2. Run e-trunk e-trunk-id

    An E-Trunk is created and the E-Trunk view is displayed or the view of an existing E-Trunk view is directly displayed.

    The member devices in an E-Trunk must be configured with the same E-Trunk ID.

    A maximum of 16 E-Trunks can be created on a device.

  3. Run priority priority

    The E-Trunk priority is set.

    The E-Trunk priority is used for master/backup negotiation between two devices. The device with a higher priority is the master. A smaller priority value indicates a higher E-Trunk priority.

    If the two devices have the same priority, the device with a smaller system ID is the master.

    By default, the E-Trunk priority of a member device is 100.
