Example: of event counter operation

Suppose the switch detects the following after a reboot:

Three duplicate instances of the PIM "Send error" during the first log throttle period for this event
Five more instances of the same Send error during the second log throttle period for this event
Four instances of the same Send error during the third log throttle period for this event

In this case, the duplicate message appears three times in the Event Log (once for each log throttle period for the event being described), and the duplicate message counter increments as shown in the following table. (The same operation applies for messages sent to any configured SNMP trap receivers.)

Table 31: How the duplicate message counter increments
Instances during 1st log throttle period	Instances during 2nd log throttle period	Instances during 3rd log throttle period	Duplicate message counter¹
3			1
	5		4
		4	9

This value always comprises the first instance of the duplicate message in the current log throttle period plus all previous occurrences of the duplicate message occurring since the switch last rebooted.
