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. Generally, a stable link is used as the active link. Therefore, after the original active link recovers, you can perform the following operations to switch traffic back to this link:

Enable the revertive switching of a Smart Link group. The system performs switching after the revertive switching timer times out.
Run the smart-link manual switch command to switch traffic back.

However, the minimum revertive switching time is 30s, and the default value is 60s. You can run the smart-link manual switch command to manually switch traffic back to the active link.

Prerequisites

To implement an active/standby switchover between links, ensure that:

The active interface and standby interface exist and are both in Up state.
Traffic is not blocked on either interface by using the smart-link command.

Precautions

Millisecond-level packet loss will occur during the switchover.
