Information
In some network topologies, you may prefer that server-facing ports on an Aggregator remain up and
continue transmitting traffic without being automatically disabled when LAG 128 connectivity to an
upstream switch/router goes down. In the event of a loss in upstream connectivity, you can enter the
uplink-state-group-1 configuration level to:
•
Disable UFD link tracking to keep downstream server ports operationally up.
•
Configure the defer timer used for UFD link tracking. The defer timer prevents unwanted flapping
of server ports when the uplink port channel (LAG 128) goes down and comes up.
To re-enable the default UFD link-tracking configuration, enter the
enable
command in
uplink-state-group-1 configuration mode.
