(Optional) Enabling Revertive Switching
Context
When the active link in a Smart Link group fails, traffic is automatically switched to the standby link. After the fault is rectified, the original active link remains blocked to ensure stable traffic transmission. To enable the original active link to transmit traffic, use either of the following methods:
- Enable revertive switching in the Smart Link group. Service traffic will be switched to the original active link when the WTR timer expires.
- Run the smart-link manual switch command to forcibly trigger link switching.
Service traffic can be switched between links in a Smart Link group only when both member interfaces are in Up state.
Procedure
- Run system-view
The system view is displayed.
- Run smart-link group group-id
The Smart Link group view is displayed.
- Run restore enable
Revertive switching is enabled for the Smart Link group.
By default, revertive switching is disabled in a Smart Link group.
- Run timer wtr wtr-time
The WTR time is set.
By default, the WTR time of a Smart Link group is 60 seconds.
