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)#
Dell(conf-uplink-state-group-1)#upstream port-channel 128
Dell(conf-uplink-state-group-1)#downstream
tengigabitethernet 0/1-32
2. Show the running configurations in the UFD-group 1.
