Yes, but if you don't know what they show, why bother?

>Also, how do I find out which OID means input, which output, errors, etc?

Try www.mibcentral.com and download their 3com drivers. In IF.mib you will
find as ifHCInUcastPkts: "The number of packets,
delivered by this sub-layer to a higher (sub-)layer, which were not
addressed to a multicast or broadcast address at this sub-layer. This
object is a 64-bit version of ifInUcastPkts"
Now you know as much as the rest of us.

Read through the MIB, and if something strikes your fancy, plot it.

Use Getif or activeSNMP and you should see words instead of dotted numbers,
which might help you.

Good luck
