[SNMP4J] able to rreceive V1 trap but not V3 trap...................

[sanjay A]

*Hi *
* *When I send a V1 trap by "SNMP4J -p V1TRAP -v 1......" utility ,I am able
to receive v1 trap, but not able to receive v3 trap by "
SNMP4J -p TRAP -v 3 -u aSecurityName....." . I can get these v3 trap through
"SNMP4J -u aSecurityName -Ol 0.0.0.0/162" utility .
I have gone through the snmp4j doc and mailing list, but couldn't find
anything.....
So please give me any idea in my code for V3 trap.....

Awaiting for the reply.....
*public* *class* V1trapListen {

                 } *else* {System.*out*.println("

           }

                }

                V1trapListen trap = *new* V1trapListen();

                *try* {

                        trap.start(address);

                } *catch* (Exception ex) {

                }

        }
}
