Usage Guidelines

Usage Scenario

If services are frequently switched between links in a Smart Link group because of temporary link disconnection, packets may be lost and system performance deteriorates. To prevent frequent switchover caused by temporary link disconnection, run the smart-link hold-time command to set the holdtime for reporting an Interface-Up or Interface-Down event. When the member interfaces of the Smart Link group alternate between Up and Down, the Smart Link group waits until the holdtime expires, and then triggers a switchover.

Prerequisites

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

Precautions

If you run the smart-link hold-time command multiple times in the same Smart Link group view, only the latest configuration takes effect.

Example
