Command Reference Interface Commands
(Optional) in the range from 0 to 60 in the unit of seconds.
(Optional) in the range from 0 to 60000 in the unit of milliseconds.
(Optional) Configures the delay after which DCD changes from Down
to Up in status.
(Optional) Configures the delay after which DCD changes from Up to
Down in status.
The default is 2 seconds.
Interface configuration mode
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 or vice versa. 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.
The following example sets the carrier delay of serial interface to 5 seconds.
Ruijie(config)# interface gigabitethernet 1/1
Ruijie(config)# carrier-delay 5
The following example sets the carrier delay of serial interface to 100 milliseconds.
Ruijie(config)# interface GigabitEthernet 1/1
Ruijie(config-if-GigabitEthernet 1/1)#carrier-delay milliseconds
100
The following example sets the DCD delay from Down to Up in status to 100 milliseconds and from
Up to Down to 200 milliseconds.
Ruijie(config)# interface GigabitEthernet 1/1
Ruijie(config-if-GigabitEthernet 1/1)# carrier-delay up
milliseconds 100 down milliseconds 200
