RADIUS Server
The RADIUS server ("Remote Authentication Dial-In User Service") is a client-
server-based security protocol for authentication and to control network access
permissions.
The RADIUS server operates using the Challenge/Response process and supports
central administration of user data, such as user ID, passwords, phone, access
rights and account data, and consists of an accounting and authentication protocol.
In combination with DHCP and PPP, configuration of dial-in system can be
automatic with RADIUS.

Figure 25: 802.1x

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.
Once the client provides the login credentials, the switch sends an authentication
request to the RADIUS server. The RADIUS server validates whether this client
is allowed access to the port.
