7.5 Switch pair uplink configuration
Configure the VLT port channel and interfaces connecting to the ACI leaf switches. Configure and enable
uplink failure detection (UFD).

Note: UFD is a feature that disables downlink interfaces due to uplink interface failures. Configuration of UFD
is a best practice to prevent downstream resources from sending traffic to a switch with failed uplinks.
