Hi Brian, Thanks for the quick reply. I understand your point, however it will take it's own time if I am going with private enterprise number, controlled by IANA.
But for now, could you help me what mistake I might be doing. I hope it is possible to extend MIB-2 standard interface, I found this example to extend standard MIB-2 interface over internet.
