on a cisco switch vs a DSL port on a DSLAM for example? I would think these
access switches would have some sort of stat you can count similar to a
utility meter reader on a house. See what it was at last month, see what is
is at this month, subtract last months from this months, and the difference
is the total amount used for that month.

Assume a 20mbit connection.  How many times can this roll over a
32 bit counter in a month if it's going full blast?

If your switch doesn’t support 64-bit counters return it.
