So the OIDs listed here are pretty much wrong. These are the OIDs on my WRT54g running the DD-WRT firmware that allow traffic graphing of the various network interfaces. On my WRT54G they are like this:
.1.3.6.1.2.1.2.2.1.10.1 ifInOctets.1 .1.3.6.1.2.1.2.2.1.16.1 ifOutOctets1 loopback
.1.3.6.1.2.1.2.2.1.10.2 ifInOctets.2 .1.3.6.1.2.1.2.2.1.16.2 ifOutOctets2 unused vlan?
.1.3.6.1.2.1.2.2.1.10.3 ifInOctets.3 .1.3.6.1.2.1.2.2.1.16.3 ifOutOctets3 unused vlan?
.1.3.6.1.2.1.2.2.1.10.4 ifInOctets.4 .1.3.6.1.2.1.2.2.1.16.4 ifOutOctets4 unused vlan?
.1.3.6.1.2.1.2.2.1.10.5 ifInOctets.5 .1.3.6.1.2.1.2.2.1.16.5 ifOutOctets5 eth0
.1.3.6.1.2.1.2.2.1.10.6 ifInOctets.6 .1.3.6.1.2.1.2.2.1.16.6 ifOutOctets6 eth1
.1.3.6.1.2.1.2.2.1.10.7 ifInOctets.7 .1.3.6.1.2.1.2.2.1.16.7 ifOutOctets7 Vlan0 LAN
.1.3.6.1.2.1.2.2.1.10.8 ifInOctets.8 .1.3.6.1.2.1.2.2.1.16.8 ifOutOctets8 Vlan1 WAN IP
.1.3.6.1.2.1.2.2.1.10.9 ifInOctets.9 .1.3.6.1.2.1.2.2.1.16.9 ifOutOctets9 br0 LAN IP

Just in case anyone was wondering. Which I somehow doubt. But I hope this post may be helpful to someone someday. But chances are if you know what an SNMP OID is you don't need my damn help.
