Mac authentication Info

Is there any information on how the mac authentication works in therms of protocol?
Like what messages does the AP send, what is the security beneath this authentication (if any). I’ve read the manual and it doesn’t say anything about that.
Is there any RFC that supports this?

lagosta, well the best way to research how it works in term of protocol simulate scenario in your network.
Set router and computer, run sniffer on the computer and run MAC authentication. See the sniffer results.
