[SNMP4J] SNMP_MP_UNKNOWN_MSGID Error

[Reddy Alok-a22624]

Hi Frank,
	Thanks for your response. But when I commented my code not to
send a response PDU explicity, the snmp4j stack does not seem to be
sending the response either. So, there is no response going back. Is
there any setup that needs to be done if the snmp4j stack has to send a
response automatically to an INFORM request? 

	Also, we have based our logic of sending response to an INFORM
explicity by looking at the sample code in SnmpRequest.java (processPdu
method).

Thanks,
Alok.

Hi Alok,

Are you explicitly sending a response PDU on an inform request? Then you
are probably sending the response twice, because SNMP4J already sends a
response when it receives an INFORM request. INFORMs are acknowledged at
SNMP protocol level not at application level!

Best regards,
Frank
