Configure the delay for reporting interface Down events

Run the carrier down-hold-time interval command in the interface view to configure the delay for reporting an interface Down event. The interval value ranges from 0 to 3600000, in milliseconds. By default, an interface Down event is reported immediately.

# Configure the delay for reporting the Down event of 10GE1/0/1 to 5 minutes.

[~HUAWEI] interface 10ge 1/0/1

[*HUAWEI-10GE1/0/1] commit


The system automatically adjusts the delay in reporting an interface Down event based on the physical layer status because interfaces of different attributes require different periods of time to restore to the Up state. The automatic adjustment ensures that fast interruption of signals on an interface does not trigger an interface Down event.
