UFD commands
clear ufd-disable
Overrides the uplink-state group configuration and brings up the downstream interfaces.
Syntax
clear ufd-disable {interface interface-type | uplink-state-group group-id}
Parameters
● interface-type — Enter the interface type.
● group-id — Enter the uplink state group ID, from 1 to 32.
Default None
Command Mode EXEC
Usage
Information
This command manually brings up a disabled downstream interface that is in an UFD-disabled error state.
After the downstream interface is up, it is not disabled until there are changes in the upstream interfaces.
This command does not affect downstream interfaces that are already up or interfaces that are not part
of the UFD group.

OS10# clear ufd-disable uplink-state-group 1
