Configuring UDLD on the Switch

Configuring a UDLD Probe Message Interval Globally

To configure the time between UDLD probe messages on ports that are in advertisement mode and are
currently determined to be bidirectional, perform this task:
Command
Step 1
Switch(config)# udld message time interval
Step 2
Switch# show udld type-slot/interface
Enabling Fast UDLD Error Reporting
By default, fast UDLD error-disables ports with unidirectional links. You can globally enable fast UDLD
to report unidirectional links with a message displayed on the console instead of error-disabling ports
with unidirectional links.
When fast UDLD error reporting is enabled, you must manually take the action appropriate for the state
Note
of the link.
To globally enable fast UDLD error reporting, perform this task:
Command
Switch(config)# udld fast-hello
error-reporting
Resetting Disabled LAN Interfaces
To reset all LAN ports that have been errdisabled by UDLD, use this command:
Command
Switch(config)# udld reset
