[mrtg] How to read data accurately from Accton 3512A and 3524A??

We have a few hubs in our lab which I am responsible for monitoring its traffic, the hub we're using are Accton CheetahHub 3512A and 3524A with the EM3560 agent installed.  I can generate a default configuration file successfully with the cfgmaker script, and the mrtg script runs fine as daemon mode in my Windows XP PC and on a Linux PC.  However, I am certain that the polled data is incorrect, the actual traffic on our network is definitely a lot more than what the results shown in MRTG.  I think there is something wrong with my configuration, but I don't know where to start.

Has anyone had any experience with this particular hub?

I've included the mrtg.cfg file generated by cfgmaker.
