If you tell MRTG to monitor port 3 on WWW.XXX.YYY.ZZZ, the values it 
returns will be according to that specific ports ('in' is in on that 
port--'out' is out on that port).  For an example of this in action 
look at this page:

http://ipgate.sktc.net/stats/link-brd.clr.html

That page shows the both ends of a T1 (16 channels).  The graphs of 
those Lucent 130s are exact opposites (which, BTW, has anyone ever 
seen a Lucent 130 *not* show all its ports on a snmpwalk?  2 of our 
130s only show the first 2 ports but can be specifically asked for 
port 4 via snmpget and it works.  Weird as hell).  If you think the 
values are incorrect you can do snmpgets for the ifInOctets and 
ifOutOctets on that port and compare those values to the values 
listed in the log for that device.  If you want to change the way it 
appears you can put a "-" at the beginning of your target:
