DLP-G127 Modify Alarm, Condition, and History Filtering Parameters
In the General tab Show Severity area, you can choose which alarm severities will show through the 
alarm filter and provision a time period during which filtered alarms show through the filter. To change 
the alarm severities shown in the filter, go to Step 3. To change the time period filter for the alarms, go 
to Step 4.
Step 3 In the Show Severity area, click the check boxes for the severities [Critical (CR), Major (MJ), Minor 
(MN), or Not Alarmed (NA)] that you want to be reported at the network level. Leave severity check 
boxes deselected (unchecked) to prevent those severities from appearing.
When alarm filtering is disabled, all alarms show.
Step 4 In the Time area, click the Show alarms between time limits check box to enable it. Click the up and 
down arrows in the From Date, To Date, and Time fields to modify the period of alarms that is shown.

continue with Step 6.
