See when someone gives you the answer to your question and you 
completely ignore it... *sigh*

Look http://www.rfc-archive.org/getrfc.php?rfc=3576 RFC 3576 CoA It's an 
extension to the RADIUS protocol. Most NAS don't support it because no 
RADIUS servers support it.

Use the IEEE 802.1x MIB, It works, It works very well. I'll try and dig 
out the relevant OIDs tomorrow if your interested...
