InformPdu
The OneInformPdu class will inform a manager about one object (OIDs), based on the Inform request.
This class represents the SNMP Inform Request PDU. Inform Requests are sent between managers. It is a kind of 'acknowlegded' trap since the receiving end should send a Response PDU as reply. The varbind list has the same elements as the TrapPduv2.
Note, this PDU should be sent to port 162 (the default trap port) by default. You will have to create a SnmpContext with the ListeningContextFace.DEFAULT_TRAP_PORT as parameter!
For SNMPv3: The receiver of an inform PDU acts as the authoritative engine.
