Having 802.1x enabled on the switch prevents any device that is not able to successfully authenticate from being able to use the ethernet port. This option is useful if your access point is located in an insecure location, and you want to prevent someone who plugs a computer or another access point into the network connection being used by your access point from being able to access the network. This feature defaults to being disabled. If "MD5 Authentication to Network with MAC Address" is selected, the access point's MAC address will be used for both the username and password. For example, an access point with the MAC Address 12-34-56-78-9A-BC would use a username and password of "123456789abc". If "MD5 Authentication to Network with Supplied Username and Password" is selected, the access point with authenticate using the username and password supplied. If you press the "Apply" button when no password is specified, the previous password will continue to be the one used. You must enter the same password twice to successfully change the password. o Local MAC Authentication-Client computers can be filtered using the unique MAC addresses of their network cards.
