Suspending an RMON Event
Suspending an RMON event deactivates it, allowing you to make changes to its
configuration settings. Use the suspend command to suspend an event.
When you suspend an RMON event, ensure that the event is not assigned to an
RMON alarm.
For example:
(config-rmonevent[1])# suspend
Configuring an RMON Alarm
An RMON alarm allows you to monitor a MIB object for a desired transitory
state. An alarm periodically takes samples of the object’s value and compares
them to the configured thresholds.
RMON allows you to configure two types of sampling, absolute and delta:
• Absolute sampling compares the sample value directly to the threshold. This
sampling is similar to a gauge, recording values that go up or down.
• Delta sampling subtracts the current sample value from the last sample taken
and then compares the difference to the threshold. This sampling is similar to
a counter, recording a value that is constantly increasing.
When a sample value crosses an alarm threshold, an associated event is generated.
To limit the number of generated events, only one event is generated when a
threshold is crossed. The CSS does not generate additional events until an
opposite threshold is crossed. For example, when a rising threshold is crossed, one
event is generated. The next event occurs only when a falling threshold is crossed.
When you associate an event to an alarm and an alarm occurs, the event defines
the action the CSS takes when an alarm occurs. For more information on events,
see the “Configuring an RMON Event” section.
