394 Monitoring Switch Traffic
Configuring RMON
This example generates a trap and creates a log entry when the number of
inbound packets are undeliverable due to errors increases by 20 or more.
First, an RMON event is created. Then, the alarm is created. The event
(event 1) generates a trap and creates a log entry. The alarm is configured for
the MIB object ifInErrors (OID: 1.3.6.1.2.1.2.2.1.14.1). The OID is the
variable. The alarm checks the variable every 30 seconds to compare the MIB
counter to the configured rising and falling thresholds. If the rise is equal to
or greater than 20, event 1 goes into effect.
To configure the switch:
1
Create the event. The trap is sent to the private SNMP community.
console#configure
console(config)#rmon event 1 description
"emergency event" log trap private
2
Create the alarm.
console(config)#rmon alarm 1
1.3.6.1.2.1.2.2.1.14.1 30 delta rising-threshold
20 1 falling-threshold 1
3
Verify the configuration.
