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 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 specifies one of the following interface types:
○ For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port/subport 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.
○ For a 50-Gigabit Ethernet interface, enter the keyword fiftyGigE then the slot/port/subport information.
○ For a 100-Gigabit Ethernet interface, enter the keyword hundredGigE then the slot/port/subport information.
○ For a port channel interface, enter the keywords port-channel then a number.
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.
