Alarm Configuration

NOTE

The Timebase applies to all enabled alarms, port-level and module-level alarms as well as repeater-level alarms. The Timebase appears in each alarms window — repeater, module, and port — but you can only edit it in the Repeater Alarms window.

Since alarm condition samples are taken at the end of the defined timebase interval, alarm conditions which occur over the span of two timebase intervals will not be detected even if the threshold is crossed within the defined timebase. For example, if the timebase is set to 10 seconds and the broadcast alarm threshold is set to 20, 20 or more broadcast packets may be detected in the last 5 seconds of one time interval and the first five seconds of the subsequent interval (for a total time interval of 10 seconds), but no alarm will be triggered because the broadcasts occurred within two different timebase intervals. The shorter the timebase, the more likely this condition is to occur.

Setting Module and Port Alarms

The following sections describe procedures for setting module and port alarm limits. Module-level alarms are based on the combined traffic within a particular module, while port-level alarms are based on an individual port.

Setting Module Alarms
