[SNMP4J] Creating V3 Trap using SNMP4j not showing variable binding at Trap Receiver

[~Kanagavelu~]

Hi Snmp4j,

Im trying to send V3 trap to a trap receiver using the below code.
Trap receiver is receiving V3 trap, but it doesn't show any Variable
bindings.
Kindly reqesting you please guide me where/what i am missing?


public void sendTrap_Version3() {

       //TrasportMapping
        TransportMapping transport;
        try {
            transport = new DefaultUdpTransportMapping();
            transport.listen();

            //Creating SNMP object
            snmp = new Snmp(transport);

             //Creating USM
            USM usm = new USM(SecurityProtocols.getInstance(), new
OctetString(MPv3.createLocalEngineID()), 0);
            SecurityModels.getInstance().addSecurityModel(usm);

            // Add user to the USM
            snmp.getUSM().addUser(
                    new OctetString("MD5DES"),
                    new UsmUser(new OctetString("MD5DES"), AuthMD5.ID, new
OctetString("MD5DESUsrAuthPwd"), PrivDES.ID,
                            new OctetString("MD5DESUsrPrivPwd")));

            // Create the target
            Address targetAddress = GenericAddress.parse("udp:
10.120.7.107/162");
            UserTarget target = new UserTarget();
            target.setAddress(targetAddress);
            target.setRetries(3);
            target.setTimeout(5000);
            target.setVersion(SnmpConstants.version3);
            target.setSecurityLevel(SecurityLevel.AUTH_PRIV);
            target.setSecurityName(new OctetString("MD5DES"));

            // Create PDU
            ScopedPDU pdu = new ScopedPDU();

           pdu.add(new VariableBinding(SnmpConstants.sysUpTime, new
OctetString(new Date().toString())));
           pdu.add(new
VariableBinding(SnmpConstants.snmpTrapOID,SnmpConstants.linkDown));
           pdu.add(new VariableBinding(SnmpConstants.snmpTrapAddress, new
IpAddress("127.3.4.1")));
           pdu.add(new VariableBinding(new OID("1.3.6.1.2.1.2.2.1.1.1"), new
Integer32(1)));

            pdu.setType(ScopedPDU.TRAP);
            snmp.send(pdu, target);

        } catch (IOException e) {
            e.printStackTrace();
        }

}
