Clearing a UFD-Disabled Interface
You can manually bring up a downstream interface in an uplink-state group that UFD disabled and is in a
UFD-Disabled Error state.
To re-enable one or more disabled downstream interfaces and clear the UFD-Disabled Error state, use the
following command.
• Re-enable a downstream interface on the switch/router that is in a UFD-Disabled Error State so that it can
send and receive traffic.
EXEC mode
clear ufd-disable {interface interface | uplink-state-group group-id }
For
interface
, enter 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 information.
• For a port channel interface, enter
port-channel {1-512 | 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:
gigabitethernet tengigabitethernet 1/1-1/2,1/5,1/9,1/11-1/12
port-channel 1-3,5
• A comma is required to separate each port and port-range entry.
