Alarms 13-7

Setting Alarm Thresholds determine when an alarm reports that a counter has exceeded a Thresholds 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 Figure 13-3 shows a counter with thresholds set manually. Alarm Threshold

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.
