Enter a time interval, between 1 and 32767 seconds, that CTP packets will be dispatched from

Recover Timer (0 or
60-1000000)
Enter a time, in seconds that a port will have to wait before being recovered from a loop-back
detection shutdown. The user may set a time between 60 and 1000000 seconds with a default
