If you're asking about graphing the *traffic* on the individual
subinterfaces under a channelized T1, that is normally not really an
MRTG-specific thing. Usually what you'd need to do is find out the
subinterface your router assigned to each channel of the channelized T1
circuit and graph each of those subinterfaces seperately (they should all
have their own OIDs). From MRTG's perspective, each subinterface is just a
"normal" interface since the router treats the subinterfaces that way for
the purposes of counters and SNMP.
