Uplink Failure Detection (UFD)

Overview

Uplink failure detection (UFD) provides detection of the loss of upstream connectivity and, if used

with network interface controller (NIC) teaming, automatic recovery from a failed link.

Commands

The UFD commands described in this chapter are:

• clear ufd-disable

• debug uplink-state-group

• description

• downstream

• downstream auto-recover

• downstream disable links

• enable

• show running-config uplink-state-group

• show uplink-state-group

• uplink-state-group

• upstream

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}
