RMON event traps

The following is an example of how to generate an SNMP trap for an RMON event.

If you want to configure a device to send an SNMP trap when the number of broadcast packets exceeds 100, do the following:

1.Configure an RMON alarm with an ID of 1 that checks etherStatsBroadcastPkts for Port 1 every 15 seconds to see if it exceeds a specified delta threshold (i.e., a change compared to the last reading). In every sample, check if etherStatsBroadcastPkts exceeds 100 packets compared to the last measurement. If it does, send an event (id 1) with “Tom” as the owner name. The event trigger is re-armed, when the falling-threshold value falls below 30 packets since the last reading.

Console(config)#rmon alarm 1 1.3.6.1.2.1.16.1.1.1.6.1 15 delta

rising-threshold 100 1 falling-threshold 80 1 owner Tom

The rising and the falling thresholds are used for the presence and absence of one specific condition, with an oscillation buffer in between (e.g. warning versus no warning, not opposite events like “too much” and “too little”), and should be near each other to be meaningful. The data monitored may oscillate between these thresholds over time, triggering multiple events, e.g. when using the settings of 100 and 80 as in the preceding example.
