[SNMP4J] Question regarding SNMPv2c Notification using SNMP4J

[Frank Fock]

Hello Vinod,

SNMPv2c/v3 traps (i.e. notifications) do not have an explicit
notification ID. Instead die PDU must have always two variable
bindings, which are

1. sysUpTime.0
2. snmpTrapOID.0

in the order given above. Any variable binding specified in the
NOTIFICATION-TYPE construct has then to follow at position
3 and following.

Best regards,
Frank
