Q7050025: Is the Windows SNMP Trap Service required to receive SNMP Traps with Network Monitor?
No, it is not required. It is even not possible to receive traps through SNMP with Network Monitor while the Windows SNMP Trap Service is running, unless you specify a different port for the ActiveXperts trap listener.
If you have the Windows SNMP Traps Service running (default on port 162), ActiveXperts Network Monitor will NOT be able to receive incoming SNMP Traps. ActiveXperts opens an UDP socket (default port 162) to listen for incoming traps; only one process at a time can listen for packets on one port. However, you can specify an alternate for ActiveXperts Network Monitor (Tools->Options->Advanced->SNMP Trap Receiver Settings).
