Usage Scenario
Monitor Link extends link redundancy of Smart Link. It synchronizes the downlink interface status with the uplink interface status so that the downstream device can be notified quickly when the uplink interface fails. The downstream device then triggers a link switchover in the Smart Link group. This prevents packet loss caused by the uplink interface failure. Before using the Monitor Link group, you must create a Monitor Link group and enter the Monitor Link group view.
Follow-up Procedure
Add uplink and downlink interfaces to the created Monitor Link group.
Precautions
Before deleting a Monitor Link group that has member interfaces, run the undo port command to delete all the member interfaces.
