2. Check the Enable All Port Threshold Alarms check box 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 will monitor CRC errors only if both the

CRC Error Enable box and the Enable All Port Threshold Alarms check

box are checked.

3. Select an event type from the Port Threshold Alarm pull-down menu.

Choose from the following options:

 CRC error monitoring

 Decode error monitoring

 ISL monitoring

 Login monitoring

 Logout monitoring

 Loss of signal monitoring

4. Check the Enable box 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 will 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 4-9.

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 will down a port if a rising trigger alarm is not cleared

after three consecutive sample windows.
