Configure the delay for reporting interface Down events

1

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] carrier down-hold-time 300000
[*HUAWEI-10GE1/0/1] commit

Note:

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.

How to set the delay in reporting interface status changes
Frequent physical status changes of an interface result in extra system costs. You can run the carrier {up-hold-time | down-hold-time} interval command in the interface view to set the delay in reporting interface status changes. The system is unaware of physical status changes of interfaces within the delay. If the interface physical status is not recovered after the delay expires, the physical status changes are reported to the system. # Set the delay in reporting an interface Up event to 1000 milliseconds on 10GE1/0/1. system-view [~HUAWEI] interface 10ge 1/0/1 [~HUAWEI-10GE1/0/1] carrier up-hold-time 1000 [*HUAWEI-10GE1/0/1] commit

There is a delay when a fixed switch interface alternates between Up and Down consecutively. Why
To prevent the interface from frequently reporting the status change event, run the carrier { up-hold-time | down-hold-time } interval command to set the delay in reporting the status change event. By default, the delay in reporting a port Up event is 2000 milliseconds, and the delay in reporting a port Down event is 0 milliseconds.

Up/Down event of the SNMP monitoring port on an S series switch
S series switches (except S1700) support enabling the LinkDown and LinkUp traps. Once the interface status changes, corresponding traps are generated. Run the snmp-agent trap enable feature-name ifnet command in the system view for configuration.
