In Scenario 2, there are two external trap receivers. The first trap receiver, referred to as the trap exploder (or the trap forwarder), receives all traps from the network and selectively forwards traps matching certain criteria to other Domain Managers and to the second trap receiver (TRAP-INCHARGE-OI). TRAP-INCHARGE-OI is mentioned in Scenario 1 - the SNMP Trap Adapter associated with the Service Assurance Manager Adapter Platform.
