Are those numbers in bits or bytes?  Do you think the numbers are low 
because you've compared them to what the switch is logging? Compare 
MRTG's output with what a "sh int xx" gives you, and keep in mind the 
proper bits/bytes conversion. If there truly is a discrepancy then you 
may want to post the relevant portions of your CFG file so that we may 
be able to help you further.  Take a look at your maxbytes setting too.
