(Optional) Configuring the E-Trunk Sequence Number Check Function


If the master device in an E-Trunk fails, to prevent an attacker from obtaining the E-Trunk packet sent by the master device and attacking the backup device, enable the E-Trunk sequence number check function.


  1. Run system-view

    The system view is displayed.

  2. Run e-trunk e-trunk-id

    The E-Trunk view is displayed.

  3. Run sequence enable

    The E-Trunk sequence number check function is enabled on the E-Trunk.

    By default, the E-Trunk sequence number check function is disabled.

    The sequence enable command must be run on both the master and backup devices in an E-Trunk. Otherwise, the E-Trunk sequence number check function fails, causing dual master devices in the E-Trunk.
