(Optional) Setting the Upper and Lower Thresholds for the Number of Active Interfaces

(Optional) Setting the Upper and Lower Thresholds for the Number of Active Interfaces

Context

The number of Up member links affects the status and bandwidth of an Eth-Trunk. To ensure that the Eth-Trunk functions properly and is less affected by member link status changes, set the following thresholds.

  • Lower threshold for the number of active interfaces: When the number of active interfaces falls below this threshold, the Eth-Trunk goes Down. This guarantees the Eth-Trunk a minimum available bandwidth.
  • Upper threshold for the number of active interfaces: It is used for improving network reliability with assured bandwidth. When the number of active interfaces reaches this threshold, you can add new member interfaces to the Eth-Trunk, but excess member interfaces enter the Down state.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface eth-trunk trunk-id

    The Eth-Trunk interface view is displayed.

  3. Run least active-linknumber link-number

    The lower threshold for the number of active interfaces is set.

    By default, the lower threshold for the number of active interfaces is 1.

    The lower threshold for the number of active interfaces on the local device can be different from that on the remote device. If the two values are different, the larger one is used.

  4. Run max active-linknumber link-number

    The upper threshold for the number of active interfaces is set.

    By default, the upper threshold for the number of active interfaces is 8.

    The upper threshold for the number of active interfaces at the local end can be different from that at the remote end. If the two values are different, the smaller one is used.

    The upper threshold for the number of active interfaces must be greater than or equal to the lower threshold for the number of active interfaces.
