Figure 43-1. rmon alarm Command Example
The above example configures RMON alarm number 10. The alarm monitors the MIB variable
1.3.6.1.2.1.2.2.1.20.1 (ifEntry.ifOutErrors) once every 20 seconds until the alarm is disabled, and checks
the rise or fall of the variable. The alarm is triggered when the 1.3.6.1.2.1.2.2.1.20.1 value shows a MIB
counter increase of 15 or more (such as from 100000 to 100015). The alarm then triggers event number 1,
which is configured with the RMON event command. Possible events include a log entry or a SNMP trap.
If the 1.3.6.1.2.1.2.2.1.20.1 value changes to 0 (falling-threshold 0), the alarm is reset and can be triggered
again.
