Hi John,

The only way I know to prevent this is to use 802.1X as the 
authentication mechanism (on wired and wireless).  The user would then 
need to insert valid credentials to gain network access.  Even if an 
evil user spoof a MAC address, he won't be able to login without valid 
credentials.

I hope it does answer your question.
