Managing Switches

Port Threshold Alarm Configuration Dialog

2.  Select the Enable All Port Threshold Alarms option to enable monitoring for all 

the individual alarm types that are enabled. The Enable All Port Threshold 
Alarms option is the master control for the individual alarms. For example, the 
switch will monitor CRC errors only if both the CRC Error Enable and Enable All 
Port Threshold Alarms options are selected.

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

the following options:

■

CRC error monitoring

■

Decode error monitoring

■

ISL monitoring

■

Login monitoring

■

Logout monitoring

■

Loss of signal monitoring

4.  Select the Enable option 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 .

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.

The switch will down a port if a rising trigger alarm is not cleared after three 

consecutive sample windows.
