– Port channel: enter port-channel {1-512}.
If a downstream interface in an uplink-state group is disabled (Oper Down state) by uplink-state
tracking because an upstream port is down, the message error-disabled[UFD] displays in the output.
• Display the current configuration of all uplink-state groups or a specified group.

(For EXEC mode) show running-config uplink-state-group [group-id]
(For UPLINK-STATE-GROUP mode) show configuration
– group-id: The values are from 1 to 16.
