To translate OIDs, you can use Cisco's free tool:

Also, here you find some info about SNMP

I suggest that you start reading :-)
A MIB is a collection of OIDs for a certain part.
You have the ifMIB, that keeps all OID's about the interfaces.
An OID id an ObjectIDentifier, it hold a value for a spicific item (Incoming bytes for an interface eth0)
You can install snmpd on your RH3 and so a snmpwalk -v2c -c community host
You'll see a lot of lines scrolling down your screen. Reading these can clear some thing out :-)
