Ideally I'd count every byte, and any deficiencies in the data would be due to unplanned outage rather than systematic short-cutting. Sampling 1 in 10 packets and multiplying the observed byte count by 10 might be better than nothing, though. Off-list, someone suggested DCU ("destination class accounting"), but that's limited to 126 classes of counters; another parameter I forgot to mention at the beginning is that there are thousands of destination addresses reached through each of these interfaces, and I'm looking for accounting by destination address, so 126 isn't going to cut it.
