Changing the keepalive interval (CLI)

By default, ports enabled for UDLD send a link health-check packet once every 5 seconds. You can change the interval to a value from 10 to 100 deciseconds, where 10 is 1 second, 11 is 1.1 seconds, and so on.


To change the packet interval to seven seconds, enter the following command at the global configuration level:
switch(config)# link-keepalive interval 70
