This should get important available OIDS for SNMP requests.
This document might seem out of place but its here because I had to do some conversion between MRTG and IfIndexes and OIDs, this helped greatly so I've copied it here and the script which does the conversion work will follow shortly.

network counters
Additional OIDs were added in version v23 SP3 and v24
| OID [dottedt & text format] | Meaning | Range of Values | Content (example) |
|---|---|---|---|
| .1.3.6.1.4.1.2021.255.3.54.1.3.32.1.1.1 | index of wireless client (if there are many clients each will have index 1-x) | integer | 1 |
| .1.3.6.1.4.1.2021.255.3.54.1.3.32.1.4.1 | Associated MAC | text | 00:ff:as:dd:44:55 |

| .1.3.6.1.2.1.31.1.1.1.6 | ifHCInOctets, the number of bytes received on the interface | integer | 64bit |
| .1.3.6.1.2.1.31.1.1.1.10 | ifHCOutOctets, the number of bytes sent on the interface | integer | 64bit |
Many of these were obtained using the unix command snmpwalk:
$ snmpwalk -v 1 -c public 192.168.1.1
(assuming 192.168.1.1 has a server running snmpd)
