Background Information

• The function of masking alarms does not take effect for the alarms that are already reported. That is, after you set a masking policy, only the newly reported alarms that meet the mask conditions are masked.

• A new masking policy is displayed in the Mask Rule dialog box. The same alarms that are reported later continue to be masked.
