Changing the keepalive retries (CLI)

By default, a port waits 5 seconds to receive a health-check reply packet from the port at the other end of the link. If the port does not receive a reply, the port tries four more times by sending up to four more health-check packets. If the port still does not receive a reply after the maximum number of retries, the port goes down.

You can change the maximum number of keepalive attempts to a value from 3 to 10.


To change the maximum number of attempts to four, enter the following command at the global configuration level:
switch(config)# link-keepalive retries 4
