Figure 5-8. Port Alarm Limits Window

The Alarm Limits window displays the following fields:

Collisions

Use the text box in this field to enter the number of collisions per good packet you wish to allow on the selected repeater, board, or port before an alarm is generated; allowable values are 1-15. For example, if you enter a value of 1, the alarm will be generated if the repeater, board, or port experiences an average of one collision per good packet received during the configured time base (see the explanation for “within,” below). In terms of percentages, an alarm threshold value of 1 would generate an alarm if 50% of your packets were collisions (one collision for every good packet); a threshold value of 15 would generate an alarm if 93.75% of your packets were collisions (15 collisions for every good packet). Therefore, the lower you set your threshold value, the lower the percentage of collisions per good packet you are allowing.

A repeater- or board-level alarm will calculate the number of collisions per good packet based on all traffic received on the repeater channel; a port-level alarm will make the calculation based on traffic on the specific port only.
