◆ The recover-time is the maximum time when recovery is triggered after a loop
is detected. The actual interval between recovery and detection will be less
than or equal to the recover-time.
◆ If the recovery time is set to zero, all ports placed in shutdown state can be
restored to operation using the loopback-detection release command. To
restore a specific port, use the no shutdown command.
