Alarm Limits

OOW Collisions

If this check box is selected, all collisions out of

 

the standard collision window (51.2 μs) will be

 

included in calculating the overall percentage of

 

errors. Out-of-window collisions are typically

 

caused by faulty network design.

Giants

If this check box is selected, the number of giant

 

packets will be included in calculating the

 

overall percentage of errors. A giant packet

 

exceeds the maximum Ethernet frame size of

 

1518 bytes (excluding the preamble).

within:

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 hours/59 minutes/59 seconds.

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 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 5-4, will appear.
