[SNMP4J] Re: Doubt about NOTIFICATION-TYPE

[Frank Fock]

Hello Carlos,

the mailing list was up, although the web interface was down unfortunately.
It is up again now ;-). Thanks for the tip!

Regarding your question: Of course it is possible to send SNMPv2c/v3
notifications of any type with SNMP4J. A contribution to the clean design
was the lack of getter/setter methods for the two required variable bindings
of notifications: sysUpTime.0 and snmpTrapOID.0. These two variable
bindings have to be added by the API user when the notification PDU
is assembled. An example for your notification ID would be:

PDU notification = new PDU();
notification.add(new VariableBinding(SnmpConstants.sysUpTime,
                        new TimeTicks(0)));
notification.add(new VariableBinding(SnmpConstants.snmpTrapOID,
                        new OID("1.3.6.1.3.1.193.100.1.1.1.2.1.1")));
// add the VBs from the NOTIFICATION-TYPE OBJECTS clause definition here
notification.add(new VariableBinding(...));
...

Hope this helps.

Best regards,
Frank
