Tools->Options->Monitoring->SNMP Traps
Customized SNMP trap listener
The program has a built-in SNMP trap listener that can be customized to listen to a different port than the default one.
Only one program may be listening on a specific port, so if you need to share SNMP trap information with other programs either on the same or a different computer, enable trap forwarding by checking the Redirect SNMP traps box and specifying the address and port of another trap listener.
SNMP Trap events
NetCrunch combines SNMP Trap events by their source and content.
Information about the number of combined SNMP Trap events is generated every 15 seconds and displayed in the Event.Count field, located in the Event Preview window.
