Example of Syslog Messages Before and After Entering the clear ufd-disable uplink-state-group Command (S50)
The following example message shows the Syslog messages that display when you clear the UFD-Disabled state from all disabled
downstream interfaces in an uplink-state group by using the clear ufd-disable uplink-state-group group-id command. All
downstream interfaces return to an operationally up state.

Displaying Uplink Failure Detection
To display information on the UFD feature, use any of the following commands.
• Display status information on a specied uplink-state group or all groups.
EXEC mode
show uplink-state-group [group-id] [detail]
• group-id: The values are from 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 species one of the following interface types:
• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port information.
• For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port/subport information.
• For a 25-Gigabit Ethernet interface, enter the keyword twentyFiveGigE then the slot/port/subport information.
