A couple of fine points. If you have been just using radius for wifi then you also need to modify your radius connection profiles on your radius server to make sure you allow authentication over ethernet (otherwise authentication will fail). Also its important to keep in mind that the initial role is VERY important with a wired connection, as this is what the computer connects as when authentication fails or does not exist (computer is sitting at login screen, and you require user/pass VIA PEAP).
Overall once this is going it is quite seemeless, I created a new AAA wired profile that had some additional tweeks over our wifi 802.1x profiles, but overall it seems like a good fit.
I am annoyed that I can not see my authenticated wired cliens in the "dashboard" view - this is really an oversite.
The documentation on the switch does need a bit of clean up though - to reflect this information...
EDIT: It appears that OS fingerprinting is also broken, device type is blank on our 802.1x wired users...
