Alarm masking

Alarm masking means that the NMS does not receive alarms from a specified object or monitor some unimportant NMS alarms. During maintenance, testing, or deployment, you can set alarm masking conditions to mask alarms that do not need concern. For some unimportant NMS alarms, you can set alarm masking on the NMS so that the NMS does not monitor these alarms to improve fault locating efficiency.
