Some NEs get offline, but no NE offline alarm is displayed on the VSM.

Alarm Information


Handling Process

Step 1     Choose Fault > Settings > Mask Rule from the main menu.

Step 2     Select an enabled alarm masking rule, right-click, and choose Property from the shortcut menu.

Step 3     On the Basic Setting tab page, check the settings of the alarm masking rule.

1.         If Alarm name is selected, check that the NE offline alarm is not selected. If Alarm name is not selected, go to the next step.

2.         In the Severity and Type areas, check that the severity and type of NE offline alarms are not selected. If the severity or type has been selected, clear the relevant check box.

Step 4     Click OK.

Root Cause

NE offline alarms are masked by setting the relevant alarm masking rules. Therefore, these alarms are not displayed in the alarm list. The alarm masking rules can be modified in order to make the alarms unmasked.
