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.

Precautions

If the network is unstable or has no requirement for the transmission delay, set a longer WTR time to prevent frequent switching.

Example

# Set the WTR time to 120 seconds for Smart Link group 1.
