Alarms 13-7
Setting Alarm
Thresholds
Thresholds determine when an alarm reports that a counter has exceeded a
certain value. You can set alarm thresholds through the network manually,
and choose any value for them that is appropriate for your application. The
network management software monitors the counters and thresholds
continually during normal operations to provide data for later calibration.
Example of an
Alarm Threshold
Figure 13-3 shows a counter with thresholds set manually.

You can associate an alarm with the high threshold, the low threshold, or
both. The actions taken because of an alarm depend on the network
management application.
