the event that will trigger it, and so on. The fields in this window are defined as follows:
• Name: The name of the alarm as it will appear in the alarm log and (optionally)
elsewhere. This defines the variable alarmName
• Enabled:Indicates whetherthealarm is “turned on”or not. If you uncheckthisbox,the
alarm will remain defined but will not be operational
• Category: The category assigned to this alarm. Select the category using the pull-down
menu at the end of the field (see the section “Creating a New Alarm Category” on
page 5-21 for more information). This defines the variable alarmCategory.
• Severity: The severity of the alarm. Select one of the five severity levels from the
pull-down menu (normal, warning, minor, major, critical). This defines the variable
alarmSeverity. The severity level also determines the sound that will be played as an
audible alert.
• EventType: Thetype of event (SNMP trap, RMON Rising trap,RMON Falling trap, or
anEPICenterevent).Thisdeterminesthelistof eventsyoucanselectintheEventName
field.
An EPICenter event is generated by EPICenter based on the results of its periodic
polling. In some cases, an EPICenter event may result from the same condition that
could also generate an SNMP orother trap. An EPICenter eventhas the advantage that
it guarantees that the condition will eventually be detected by polling even if the
corresponding trap is missed.
See Appendix Dfor a description of the EPICenter and SNMP events from which you
can choose.
Certain SNMP events require configuration on the switch in order to enable specific
trap conditions.
You defineRMONevents and CPU Utilizationevents through theEventConfiguration
page of the EPICenter Alarm System. RMON events can only be configured on
switches running ExtremeWare 6.1 or later. CPU Utilization rules can only be
configured on switches running ExtremeWare 6.2 or later.
