RMON Configuration Examples
Network requirements
z
As shown in Figure 42-1 , the Switch to be tested is connected to a remote NMS through the
Internet. Ensure that the SNMP agents are correctly configured before performing RMON
configuration.
z
Create an entry in the extended alarm table to monitor the information of statistics on the Ethernet
port, if the change rate of which exceeds the set threshold, the alarm events will be triggered.

# Add the event entries numbered 1 and 2 to the event table, which will be triggered by the following
extended alarm.

[device] rmon event 2 trap 10.21.30.55
# Add an entry numbered 2 to the extended alarm table to allow the system to calculate the alarm
variables with the (.1.3.6.1.2.1.16.1.1.1.9.1+.1.3.6.1.2.1.16.1.1.1.10.1) formula to get the numbers of all
the oversize and undersize packets received by GigabitEthernet 1/0/1 that are in correct data format
and sample it in every 10 seconds. When the change ratio between samples reaches the rising
threshold of 50, event 1 is triggered; when the change ratio drops under the falling threshold, event 2 is
triggered.
