Most likely, you're getting the right amount of traffic that's going 
THROUGH your MSFC.  Unfortunately, because the MSFC populates the 
forwarding logic on the switching modules, a large portion of your 
traffic never goes through the MSFC.

You'll need to monitor the physical ports for "accurate" statistics.
