Chapter 6 Deploying Wireless Networks : Configuring a WiFi LAN : Configuring user authentication : MAC-based authentication
  
MAC-based authentication
Wireless clients can also be supplementally authenticated by MAC address. A RADIUS server stores the allowed MAC address for each client and the wireless controller checks the MAC address independently of other authentication methods.
MAC-based authentication must be configured in the CLI. In the following example, MAC-based authentication is added to an existing access point “vap1” to use a RADIUS server at 192.168.1.95:
config wireless-controller vap
edit vap1
set radius-mac-auth enable
set radius-mac-auth-server 192.168.1.95
end
