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.
