Setting the DelayDown timer
When the Tx line fails, some ports might go down and then come up again, causing optical signal jitters on the Rx line. To prevent the device from removing neighbor entries in such cases, set the DelayDown timer for the device. The device starts the DelayDown timer when a port goes down due to a Tx line failure. If the port remains down when the timer expires, the device removes the DLDP neighbor information. If the port comes up, the device takes no action.
