  Yeah.  The client sends a DHCP discover, and the switch ignores it... because it's waiting for EAP!

  My suspicion is that most switch vendors hire engineers who know nothing about networks, and who don't use the equipment they're building.

  Anyways... I have a program this fall to get in close touch with more of the vendors.  I already have relationships with a few, but more would be good.  Along with a push of "PLEASE, if you have RADIUS questions, just ASK.  Don't ship crap."
