Usage Guidelines

Usage Scenario

When the active link in a Smart Link group fails, traffic is switched to the standby link. The original active link remains blocked after recovery. To enable the original active link to transmit traffic, enable the revertive switching function in the Smart Link group. Traffic is switched back to the original active link when the WTR timer expires.

Prerequisites

A Smart Link group has been created using the smart-link group command.

Follow-up Procedure

By default, the WTR timer is 60 seconds. You can run the timer wtr command to change the value.

Precautions

Link switching is performed only when both member interfaces in the Smart Link group are in Up state.
Do not run the undo restore enable command during revertive switching because this will cause a revertive switching failure.

Example

# Enable the revertive switching of Smart Link group 1.

<HUAWEI> system-view
[HUAWEI] smart-link group 1
[HUAWEI-smlk-group1] restore enable
