Configuring port threshold alarms

You can configure the switch to generate alarms for selected events. Configuring an alarm involves choosing an event type, rising and falling triggers, a sample window, and finally enabling or disabling the alarm.

1.Select Switch > Port Threshold Alarm Configuration. The Port Threshold Alarm Configuration dialog box is displayed (Figure 24).

The Port Threshold Alarm Configuration dialog box prompts you to enable or disable all alarms, select an event, set triggers, set a sample window and enable or disable an individual alarm.

2.Check Enable All Port Threshold Alarms to enable monitoring for all the individual alarm types that are enabled.

The Enable All Port Threshold Alarms check box is the master control for the individual alarms. For example, the switch monitors CRC errors only if both CRC Error Enable and Enable All Port Threshold Alarms are checked.

3.Select an event type from the Port Threshold Alarm drop-down list. Choose from the following options:

CRC error monitoring

Decode error monitoring

Login monitoring

Logout monitoring

Loss of signal monitoring

4.Check Enable to make the alarm eligible for use.

5.Enter a value for the rising trigger.

A rising trigger alarm is generated when the event count per interval exceeds the rising trigger. The switch does not generate another rising trigger alarm for that event until the count descends below the falling trigger and rises again above the rising trigger. Consider the example in Figure 25.

6.Enter a value for the falling trigger.

A falling trigger alarm is generated when the event count per interval descends below the falling trigger.

Note: The switch disables a port if a rising trigger alarm is not cleared after three consecutive sample windows.
