The commented out entries will usually be prefixed with comments indicating
why they are commented out (either zero speed, or admin disabled, etc)

I would suggest you try using SNMPv2.  Add ::::2 to the end of the SNMP
target definition, or run cfgmaker with "--snmp-options=:::::2"

This means that, while polling the interface of the device in question, MRTG
was not able to get a valid value.  There are many reasons for this, though
the usual one is that the community string or ACLs are wrong.  Other
possibilities are that you're using the wrong SNMP version (try v2c!), that
your returned data are out of range, and so on. Try running MRTG
interactively with "--debug=tarp,snpo,eval,log" to get more information as
to what is being asked for and what is being returned.
