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.

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 traffic.
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
/subport |
slot/
port/subport-range
}
•
40-Gigabit Ethernet:
fortyGigE
{
slot/port
}
•
Port channel:
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:
gigabitethernet 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.
