Usage Guide
This parameter refers to the delay after which the carrier detection signal DCD of the interface link
changes from the Down status to the Up status. If the DCD changes within the delay, the system will
ignore such changes without disconnecting the upper data link layer for renegotiation.
If the DCD carrier is disconnected for a long time, the parameter should be set longer to accelerate
route aggregation so that the routing table can be converged more quickly. On the contrary, if the
DCD carrier interruption period is shorter than the time used for route aggregation, you should set the
parameter to a higher value to avoid unnecessary route vibration.
Configuration
Examples
The following example shows how to configure the carrier delay of serial interface to 5 seconds:
Ruijie(config)# interface gigabitethernet 1/1
Ruijie(config)# carrier-delay 5
