User Guidelines
Lower message time values will detect the unidirectional links more quickly
at the cost of higher CPU utilization.
The message interval is also used to age out UDLD entries from the internal
database. UDLD entries are removed after three times the message interval
and the discovery process starts again.
Example
This example sets the UDLD message transmit interval to 10 seconds.
console(config)#udld message time 10
