Uplink Failure Detection (UFD)
Uplink failure detection (UFD) provides detection of the loss of upstream connectivity and, if you use this with network interface controller
(NIC) teaming, automatic recovery from a failed link.
NOTE: In Standalone, VLT, and Stacking modes, the UFD group number is 1 by default and cannot be changed.

clear ufd-disable
Re-enable one or more downstream interfaces on the switch/router that are in a UFD-Disabled Error state so that an interface can send
and receive trac.
Syntax
clear ufd-disable {interface interface | uplink-state-group group-id}
Parameters
interface interface Specify one or more downstream interfaces. For interface, enter one of the following
interface types:
• 10 Gigabit Ethernet: tengigabitethernet {slot/port |slot/ port-
range}
• Port channel: 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:
tengigabitethernet 1/1-2,5,9,11-12 port-channel 1-3,5. A comma is
required to separate each port and port-range entry.
uplink-state-group
group-id
Re-enables all UFD-disabled downstream interfaces in the group. The valid group-id
values are from 1 to 16.
Defaults A downstream interface in a UFD-disabled uplink-state group is also disabled and is in a UFD-Disabled Error state.
