Alarm Configuration

Figure 4-8. Sample Rising and Falling Threshold Pairs

TIP

The current version of the Basic Alarms window only allows you to conÞgure a single pair 
of thresholds for each alarm variable on each interface; be sure to keep this hysteresis 
function in mind when conÞguring those threshold values.
