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 range from 10 seconds to
23 hrs/59 mins/59 secs.
Configuring Alarms
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.
Setting the Alarm Limits Time Interval
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,
Figure 5-9 , opens.
