If the link is already in the profile link-up mode when you enter this command, the new value does not
go into effect immediately. Instead, it becomes effective after the profile link goes down and comes back
up.
Examples: This example shows how to establish a delay of 1 second before the link reports a failure:
Switch(config)# interface longreachethernet0/1
Switch(config-if)# persistence 1
You can verify your settings by entering the show controllers lre status privileged EXEC command.
