Your config doesn't show snmp version 2. It's sanitized, so you might have
just skipped it, but you probably need to show it.
If using snmp v2, the relevant counters are ifHCInOctets and ifHCOutOctets
You currently have maxbytes as 5mb/s and absmax as 100mb/sec. If all of the
traffic is over 100mb/sec then MRTG will ignore it.
Have you tried taking several snapshots of ifHCOutOctets to see if it is
Cisco subinterfaces (like eth0.10) have a long history of bad mibs... Might
be a bug in whatever version of code you are running.
