Alarm Limits

This field displays the user-configurable alarm limit timer interval: the amount of time the 
selected statistics will be counted before being compared to the configured thresholds. The 
allowable values are 10 seconds to 23 hrs/59 mins/59 secs.

You configure alarms by choosing the alarm you wish to enable, setting the threshold to 
the desired level, and selecting a time interval within which that threshold must occur. 
You can base the alarms on: 

•

Number of collisions per good packet

•

Number of total packets

•

Number of broadcast packets

•

Percentage of error packets

You can also configure board or port alarm limits so that the board or port will be disabled 
when an alarm limit is reached.

To set the time interval within which the defined alarm thresholds must be reached in 
order to trigger an alarm:

1.

Click on the clock symbol 

 next to the within: text box in any one of the 

alarm limits windows; the interval you set applies to all configured alarms at all 
levels. The Alarm Interval window, 

, will appear.

For more detailed definitions of these statistics and information on the possible network 
conditions they represent, consult the Enterasys Network Troubleshooting Guide, 
included with this package.
