udld message time
Use the udld message time command in Global Configuration mode to
configure the interval between the transmission of UDLD probe messages on
ports that are in the advertisement phase.
Use the no form of the command to return the message transmission interval
to the default value.
Syntax
udld message time message-interval
no udld message time
• message-interval — UDLD message transmit interval in seconds. Range
is 7 to 90 seconds.
Default Configuration
The default message transmit interval is 15 seconds.
Command Mode
Global Configuration mode
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
