Configuration Examples for RMON
Configuring an RMON Alarm Number: Example
The following example shows how to configure an RMON alarm number:
Switch(config)# rmon alarm 10 ifEntry.20.1 20 delta rising-threshold 15 1
falling-threshold 0 owner jjohnson
The alarm monitors the MIB variable ifEntry.20.1 once every 20 seconds until the alarm is disabled and
checks the change in the variable’s rise or fall. If the ifEntry.20.1 value shows a MIB counter increase
of 15 or more, such as from 100000 to 100015, the alarm is triggered. The alarm in turn triggers event
number 1, which is configured with the rmon event command. Possible events can include a log entry
or an SNMP trap. If the ifEntry.20.1 value changes by
0, the alarm is reset and can be triggered again.
Creating an RMON Event Number: Example
The following example creates RMON event number 1:
Switch(config)# rmon event 1 log trap eventtrap description "High ifOutErrors" owner
jjones
The event is defined as High ifOutErrors and generates a log entry when the event is triggered by the
alarm. The user jjones owns the row that is created in the event table by this command. This example
also generates an SNMP trap when the event is triggered.
Configuring RMON Statistics: Example
This example shows how to collect RMON statistics for the owner root:
Switch(config)# interface gigabitethernet1/1
Switch(config-if)# rmon collection stats 2 owner root
