Examples
# Add entry 1 in the alarm table and sample the node 1.3.6.1.2.1.16.1.1.1.4.1 at a sampling interval of
10 seconds in absolute sampling type. Trigger event 1 when the sampled value is greater than or
equal to the rising threshold of 5000, and event 2 when the sampled value is less than or equal to the
falling threshold of 5. Set the owner of the entry to be user1 .

1.3.6.1.2.1.16.1.1.1.4 is the OID of the leaf node etherStatsOctets. It represents the statistics of the
received packets on the interface, in bytes. In the above example, you can use etherStatsOctets.1 to
replace the parameter 1.3.6.1.2.1.16.1.1.1.4.1, where 1 indicates the serial number of the interface
statistics entry. Therefore, if you execute the rmon statistics 5 command, you can use
etherStatsOctets.5 to replace the parameter.
The above configuration implements the following:
z
Sampling and monitoring interface GigabitEthernet 1/0/1
z
Obtaining the absolute value of the number of received packets. If the total bytes of the received
packets reach 5,000, the system will log the event; if the total bytes of the received packets are no
more than 5, the system will take no action.
rmon event
Syntax
rmon event entry-number [ description string ] { log | log-trap log - trapcommunity | none | trap
trap - community } [ owner text ]

Parameters
entry-number : Event entry index, in the range 1 to 65,535.
description string : Event description, a string of 1 to 127 characters.
log : Logs the event when it occurs.
log-trap log - trapcommunity : Log and trap events. The system performs both logging and trap sending
when the event occurs. log - trapcommunity indicates the community name of the network management
station that receives trap messages, a string of 1 to 127 characters.
