Events
RMON events and alarms work together to notify you when values in your
network are outside of a specified range. When values pass the specified ranges,
the alarm is triggered and “fires.” The event specifies how the activity is recorded.
How events work
An event specifies whether a trap, a log, or a trap and a log is 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.
