How to Monitoring certain Statistics on a Router via SNMP

[Redfox1]

I'm interested in monitoring (graphing) certain stats of a router (specifically an Cabletron-2000.)

I'm already using MRTG to graph basic traffic of each port on the router.

1. How do I find out what specific OIDs to give to MRTG?
2. How to I GET information out of the Router?

I am somewhat familiar with SNMP, MIB, MIB-II, snmpwalk but appearantly not well enough to figure this one out...

I thought I had the right OIDs, but when I query it I get nogthing back.

I am using the right community strings... since I'm getting port based traffic from the SSR already.

I'm open to other examples not just specific ones to the SSR>
