The 802.1X authentication profile configuration settings are divided into two tabs, Basic and Advanced. The Basic tab displays only those configuration settings that often need to be adjusted to suit a specific network. The Advanced tab shows all configuration settings, including settings that do not need frequent adjustment or should be kept at their default values. If you change a setting on one tab then click and display the other tab without saving your configuration, that setting will revert to its previous value.

token cards such as SecureID and the use of LDAP or RADIUS as the user authentication

 

server. You can also enable caching of user credentials on the controller as a backup to

 

an external authentication server.
