This section describes the usage scenario of transmission alarm filtering intervals, and the pre-configuration tasks and operation procedure for configuring the transmission alarm filtering intervals. If the lifetime (interval between alarm generation and alarm clearance) of an alarm is less than the generation alarm filtering interval, the alarm is filtered out as a burr. Otherwise, the alarm is considered as a normal alarm.
In the scenario where a router is connected to a transmission device, if the network is unstable, a large number of burr alarms may be generated. As a result, the physical status of interfaces will frequently change between up and down. If a transmission alarm filtering interval is configured, the alarms whose lifetime is shorter than the interval will be ignored.
Transmission alarm filtering intervals can be configured globally or on an interface. The global configuration takes effect on interfaces supporting the function. The relationship is as follows:
In VS mode, global transmission alarm filtering intervals are supported only by the admin VS.
Before configuring transmission alarm filtering intervals, complete the following tasks:
Configuring Transmission Alarm Customization on the router's interface connected to the transmission device.
The alarm filtering function on an interface takes effect only after transmission alarm customization is configured on the interface.
The system view is displayed.
Generation alarm filtering is enabled globally, and an interval for filtering generation alarms is configured globally.
Clearance alarm filtering is enabled globally, and an interval for filtering clearance alarms is configured globally.
The configuration is committed.
