Displaying Uplink Failure Detection
To display information on the UFD feature, use any of the following commands.
• Display status information on a specified uplink-state group or all groups.
EXEC mode
show uplink-state-group [group-id] [detail]
• group-id: The values are 1 to 16.
• detail: displays additional status information on the upstream and downstream interfaces in each group.
• Display the current status of a port or port-channel interface assigned to an uplink-state group.
EXEC mode
show interfaces interface
interface specifies one of the following interface types:
• 10-Gigabit Ethernet: enter tengigabitethernet slot/port.
• 10-Gigabit Ethernet: enter tengigabitethernet slot/port.
• 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.
EXEC mode or UPLINK-STATE-GROUP mode
(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.
The following example shows viewing the uplink state group status for an S50 system.
