To trigger the event associated with an alarm condition, you must create the event with the
rmon
event
command.
RMON samples the monitored alarm variable at the specified sampling interval, compares the
sampled value with the predefined thresholds, and does one of the following:
•
Triggers the event associated with the rising alarm if the sampled value is equal to or greater
than the rising threshold.
•
Triggers the event associated with the falling alarm if the sampled value is equal to or less than
the falling threshold.
Examples
# Create an alarm entry to perform absolute sampling on the number of octets received on
GigabitEthernet 1/0/1 (object instance 1.3.6.1.2.1.16.1.1.1.4.1) at 10-seconds intervals. If the
sampled value reaches or exceeds 5000, log the rising alarm event. If the sampled value is equal to
or less than 5, take no actions.

In this example, you can replace 1.3.6.1.2.1.16.1.1.1.4.1 with etherStatsOctets.1, where 1 is the
statistics entry index for the interface. If you execute the
rmon
statistics 5
command, you can use
etherStatsOctets.5 to replace 1.3.6.1.2.1.16.1.1.1.4.5.
