Events

RMON events and alarms work together to notify you when values in your network go out of a specified range. When values pass the specified ranges, the alarm is triggered and "fires." The event specifies how the activity is recorded.

An event specifies whether a trap, a log, or a trap and a log will be generated to view alarm activity. When RMON is globally enabled, two default events are generated:

• RisingEvent
• FallingEvent

The default events specify that when an alarm goes out of range, the "firing" of the alarm will be tracked in both a trap and a log. For example, when an alarm fires at the rising threshold, the rising event specifies that this information be sent to both a trap and a log. Likewise, when an alarm passes the falling threshold, the falling event specifies that this information be sent to a trap and a log.

To create an event with default rising and falling settings:

1. From the Device Manager menu bar, choose Rmon > Alarms > Event > Insert.

If RMON is not globally enabled, a dialog box displays the following message:

RMON is currently disabled. Do you want to enable it now?

2. Click Yes.

When you create events in this manner, two default events (a rising event and a falling event) are created.

To create events with nondefault parameter values:

1. From the Device Manager menu bar, choose Rmon > Alarms > Event.
2. Click Insert to display the RmonAlarms, Insert Event dialog box.
3. Type a name for the event in the Description text box.
4. Select the type of event you want.

The default setting is log-and-trap. You may opt to set the event type to log to save memory or to snmp-log to reduce traffic from the switch.

If you select snmp-trap or log, trap receivers must be set.

5. Click Insert.
