public class OneInformPdu

extends InformPdu

The OneInformPdu class will inform a manager about one (1) object (OIDs), based on the Inform request.

Specify with addOid() the OIDs that should be informed with this InformPdu request. No more than count (see constructor) should be added. Add an Observer to the InformPdu with addObserver(), and send the InformPdu with send().

Note this PDU should be send to port 162 (the default trap port) by default. You will have to create a SnmpContext with the DefaultTrapContext.DEFAULT_TRAP_PORT as parameter!

Note: The stack so far only supports sending an Inform. Receiving an Inform and replying with a Response is NOT yet supported!

                    java.lang.String oid,
                    java.util.Observer o)
