Less than 200 bytes in 5 minutes?  Mrtg is accurately displaying what your
mib is reporting - essentially zero traffic.  Knowing that it is a
sub-interface you are using, I would suspect you have a routing problem on
your box in which packets are received on this interface and transmitted out
a "default" interface.  More than likely the only traffic transmitted out
this interface is arp.
