clear ufd-disable {interface interface | uplink-state-group group-id}
For interface, enter one of the following interface types:
• 10 Gigabit Ethernet: enter tengigabitethernet {slot/port | slot/port-range}
• Port channel: enter port-channel {1-128 | port-channel-range}
• Where port-range and port-channel-range specify a range of ports separated by a dash (-) and/or individual ports/
port channels in any order; for example:
tengigabitethernet 0/1-2,5,9,11-12
port-channel 1-3,5
• A comma is required to separate each port and port-range entry.
clear ufd-disable {interface interface | uplink-state-group group-id}: re-enables all UFD-disabled
downstream interfaces in the group. The range is from 1 to 16.
Example of Syslog Messages Before and After Entering the clear ufd-disable uplink-state-group Command
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.
