In most corporate environments, the Cisco packet counts should be greater than
or equal to Snort (due to the "other" protocols that are almost always present). 
Dropped packets can't be compared between the two devices.

If Snorts packet counts are greater than the Cisco, then obviously one of the
two can't count.
