ifINOctets and ifOUTOctets will return the actual number of octets that
traversed the particular porter. The Packet count, will be a much lower
number since packets can be anywhere from 64bytes to 1500+ bytes in
size. You just want to look at the octets count, this will include
broadcasts, multicasts, unicasts that traverse the port.
Using cfgmaker on the switches IP address should build a config file
with everything you need to know.
