Thanks for the additional info.  We mainly were using it to compare against 
itself, especially the retransmissions. There were some telltale signs that we 
were having controller problems and a spike in retransmissions was a big one.

If you are doing EAP-PEAPv0/MS-CHAPv2 then there will be many (a dozen
or so) Access-Request packets sent per user authorization occurrence.

The WiSM sends Access-Request (type 1) and the radius server answers
with Auth-Challenge (type 11).   This repeats back and forth many times
until the radius server finally answers the final Auth-Request with
either an Auth-Accept (type 2) or Auth-Reject (type 3).


Just be clear what you're counting when comparing with other
institutions or you will be off by quite a bit.   Apples-to-apples, etc.
