Dave, Thank you for the reply. I got the trap OID from the second varbind as you said and my code is working very well now.

If this is an SNMPv1 trap, then you'll need to look at the two integer trap fields (generic and specific), and possibly the enterprise field (an OID). If this is an SNMPv2 notification (i.e. SNMPv2c or SNMPv3), then the trap OID is the second varbind of the varbind list. The Net-SNMP snmptrapd application handles this by converting SNMPv1 traps into the equivalent SNMPv2 form, and always works with the snmpTrapOID.0 varbind. This is then used to decide what to do with that particular trap (logging it, passing it to a script for processing, or forwarding it to another system).
