Alarm Configuration
Accessing the Basic and Advanced Alarms windows; creating a basic alarm; creating an advanced alarm; creating events; assigning actions to events; viewing the event log
Through the RMON Alarm and Event functionality supported by your SmartSwitch 7000, you can conÞgure alarms and events (and, where appropriate, actions) for each available interface.
The Alarm, Event, and Actions windows described in this chapter are identical to those

About RMON Alarms and Events
Although Alarms and Events are deÞned as separate RMON groups, neither one can function properly without the other: you can deÞne an alarm threshold, but if it doesnÕt point to an event, there will be no indication that the threshold has been crossed; similarly, you can deÞne an event, but unless it is attached to an alarm threshold, it wonÕt be triggered. Each is an essential part of the same notiÞcation process: the alarm deÞnes a set of conditions you want to know about, and the event determines the means of letting you know those conditions have occurred.
Events are also an integral part of the Þlter and packet capture functionality: you can start and stop packet capturing in response to events, or a successful packet capture can generate its own event.
SPECTRUM Element Manager provides two means for conÞguring RMON alarms: using the Basic Alarms window, you can deÞne both rising and falling alarm thresholds for up to three
