17.3 What You Need to Know
IEEE 802.1x authentication uses the RADIUS (Remote Authentication Dial In User
Service, RFC 2138, 2139) protocol to validate users.
17.3.1 IEEE 802.1x Authentication
The following figure illustrates how a client connecting to a IEEE 802.1x
authentication enabled port goes through a validation process. The Switch
prompts the client for login information in the form of a user name and password.
When the client provides the login credentials, the Switch sends an authentication
request to a RADIUS server. The RADIUS server validates whether this client is
allowed access to the port.

17.4 Port Authentication Configuration
To enable port authentication, first activate the port authentication method (both
on the Switch and the port(s)) then configure the RADIUS server settings.
