Uplink Failure Detection (UFD)

Uplink failure detection (UFD) provides detection of the loss of upstream connectivity and, if you use this

with NIC teaming, automatic recovery from a failed link.

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 traffic.

clear ufd-disable {interface interface | uplink-state-group

uplink-state-

group group-id

A downstream interface in a UFD-disabled uplink-state group is also disabled and is

in a UFD-Disabled Error state.

CONFIGURATION

Uplink Failure Detection (UFD)

Specify one or more downstream interfaces. For interface,

enter one of the following interface types:

10 Gigabit Ethernet: tengigabitethernet {slot/

port |slot/ port-range}

40 Gigabit Ethernet: fortyGigE {slot/port |slot/

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.

Re-enables all UFD-disabled downstream interfaces in the

group. The valid group-id values are from 1 to 16.
