transmission-alarm holdup-timer (System view)
Function
The transmission-alarm holdup-timer command enables the global filtering function for alarm-clear messages and sets an interval for filtering alarm-clear messages.
The undo transmission-alarm holdup-timer command disables the global filtering function for alarm-clear messages.
By default, the filtering function for alarm-clear messages is enabled globally.
This command is supported only on the NetEngine 8000 F1A.
Usage Guidelines
Usage Scenario
The frequent generation of alarms causes the interface status to continuously alternate between Up and Down at the physical layer. To enable the interface to ignore alarms and clear alarms within a specified interval, run the transmission-alarm holdup-timer command to set an interval for filtering alarm-clear messages.
Prerequisites
The alarm customization function has been enabled on an interface.
Configuration Impact
After this command is executed, the interface goes Up after <holdup-timer> milliseconds.
Precautions
In VS mode, this command is supported only by the admin VS.
Specify the holdup-time parameter based on the flapping frequency of an interface. If this command is run in the system view and the non-default configuration of this command exists in the interface view, the configuration on the interface takes effect. If the configuration in the interface view is the default configuration, the global configuration takes effect.
