HP MSR2000/3000/4000 Router Series Network Management and Monitoring Command Reference

177
To create an alarm entry successfully, make sure it has a different alarm variable, sampling interval,
sample type, rising threshold, or falling threshold than any existing alarm entry. Two entries are
considered duplicate if all these parameters are the same.
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 Ethernet 1/1
( o b j e c t i n s t a n c e 1. 3 . 6 .1. 2 .1.16 .1.1.1. 4 .1) a t 10 - s e c o n d s 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
