what is the second varbind of an SNMPv2 notification ?

[narendra1310]

Hi all,

I am newbie to SNMP. I wrote an snmp trap generator application (with the help of net-snmp snmptrap.c application file which in-turn using netsnmp libraries), for sending SNMP v2 traps (notifications) on particular events from our enterprise product. Therefore, it will be an enterprise specific V2 trap. And also i defined my mib (MY-MIB.txt).

For Example :
Here is my enterprise notification oid :
my_enterprise_notification_oid = 1.3.6.1.4.1.3000.1.400

and here is a standard snmpTrapOID.0 :
snmptrap = 1.3.6.1.6.3.1.1.4.1.0

My snmp trap Daemon recieves like this :
dumph_recv: VarBindList
dumph_recv: VarBind
dumph_recv: Name
dumpx_recv: 06 0A 2B 06 01 06 03 01 01 04 01 00
dumpv_recv: ObjID: SNMPv2-MIB::snmpTrapOID.0
dumph_recv: Value
dumpx_recv: 06 0C 2B 06 01 04 01 82 96 29 01 00 83 10
dumpv_recv: ObjID: MY-MIB::my_enterprize_notitication_oid

2010-10-27 17:21:12 localhost [UDP: [127.0.0.1]:33067->[127.0.0.1]:
SNMPv2-MIB::snmpTrapOID.0 = OID: MY-MIB::my_enterprize_notitication_oid MY-MIB::alertSender.0 = STRING: "Hello"

Now i want to know. what is the second varbind (Name) for an SNMPv2 enterprise specific notification ?

weather it will be my_enterprize_notitication_oid or snmpTrapOID.0 ?

if second varbind name should be my_enterprize_notitication_oid in V2 enterprise specific notification, then how to structure it in my SNMPv2 PDU.

In general:
What is the structure of SNMPv2 PDU for enterprise specific notification ?

Please help me regarding

Thanks in advance
