transmission-alarm damping

Function

The transmission-alarm damping command enables the suppression function for all transmission alarms that affect the physical statuses of interfaces, and configures suppression parameters.

The undo transmission-alarm damping command disables the suppression function.

By default, transmission alarm suppression is disabled.

This command is supported only on the NetEngine 8000 F1A.

Parameters

Parameter	Description	Value
suppress suppress	Specifies the alarm suppression threshold.	The value is an integer ranging from 2 to 19999. The default value is 2000. This value must be larger than or equal the alarm reuse threshold and smaller than the alarm upper threshold.
reuse reuse	Specifies the alarm reuse threshold.	The value is an integer ranging from 1 to 19998. The default value is 750. This value must be smaller than or equal the alarm suppression threshold.
ceiling ceiling	Specifies the alarm upper threshold.	The value is an integer ranging from 1001 to 20000. The default value is 6000. The value must be larger than or equal the alarm suppression threshold.
decay-ok decay-ok	Specifies the half decay period of alarm clearance.	The value is an integer ranging from 500 to 10000, in milliseconds. The default value is 1000.
decay-ng decay-ng	Specifies the half decay period of alarm generation.	The value is an integer ranging from 500 to 10000, in milliseconds. The default value is 1000.

Usage Guidelines

Usage Scenario

Frequent generation of alarms will cause the physical status of interfaces to switch between Up and Down. You can use the transmission-alarm damping command to suppress alarms and to configure suppression parameters. In this manner, network flapping can be suppressed.

Prerequisites

Transmission alarm customization has been enabled on an interface.

Example

# Enable transmission alarm suppression on 10GE 0/1/0, and set the alarm suppression threshold, reuse threshold, upper threshold, half decay period of alarm clearance, and half decay period of alarm generation to 1000, 500, 8000, 2000 milliseconds, and 2000 milliseconds, respectively.
