Hi!

Thanks for the reply. I actually found what is going on. First of all,
I did not specify the snmp session as version 2 session. Then scotty
discard the version 2 trap for non version 2 session. I just figure out
how to specify the version 2 session. And the version 2 trap is now properly
parsed. It works really well.

With best regards,
