Uplink Failure Detection (UFD)
UFD provides detection of the upstream connectivity loss and, if used with network interface controller
(NIC) teaming, automatic recovery from a failed link.
1. Create the UFD group and associate the downstream and upstream ports.
Dell#configure
Dell(conf)#uplink-state-group 1
Dell(conf-uplink-state-group-1)#

NOTE: In this example, if port-channel 128 goes down, the downstream interfaces are brought
operationally down (set to UFD error-disabled). Similarly, if the upstream port-channel goes up,
the downstream ports are brought up (cleared from UFD error-disabled).
