udld reset

Use the udld reset privileged EXEC command to reset all interfaces disabled by the UniDirectional Link
Detection (UDLD) and permit traffic to begin passing through them again (though other features, such
as spanning tree, Port Aggregation Protocol (PAgP), and Dynamic Trunking Protocol (DTP) still have
their normal effects, if enabled).

Usage Guidelines If the interface configuration is still enabled for UDLD, these ports begin to run UDLD again and are
disabled for the same reason if the problem has not been corrected.
Examples This example shows how to reset all interfaces disabled by UDLD:
Switch# udld reset
1 ports shutdown by UDLD were reset.
You can verify your setting by entering the show udld privileged EXEC command.
