<Big sigh of relief>!! We have about 5 proprietary MIBs, so this feature is
absolutely essential.

Why must I specify a table? I want the whole MIB.

Absolutely. I'm going to do that next. But there is a lot of proprietary
MIBs we have and I'm trying to understand how hard it will be to code those
to use net-snmp agent. Any input? So I may decide whether I can use net-snmp
or not ? Your response could potentially save me a lot of time.

I'm also having a real hard time trying to figure out how to get the if-mib
(ifTable/ifXTable) to plug into our system. Basically I don't know what
modules I need to modify to plug into our user code world from the net-snmp
world so the ifInOctets etc can be correctly populated by polling the
hardware device.

Thank you !
