Radius Server
RADIUS proxy servers are used for centralized administration. Remote Authentication Dial in User Service (RADIUS) is a networking protocol that provides centralized Authentication, Authorization, and Accounting (AAA) management for users that connect and use a network service for greater convenience. RADIUS is a server protocol that runs in the application layer, using UDP as transport. The Network switch with port-based authentication and all have a RADIUS client component that communicates with the RADIUS server. Clients connected to a port on the switch must be authenticated by the Authentication server before accessing services offered by the switch on the LAN. Use a RADIUS server to authenticate users trying to access a network by relaying Extensible Authentication Protocol over LAN (EAPOL) packets between the client and server. The RADIUS server maintains a user database, which contains authentication information. The switch passes information to the configured RADIUS server, which can authenticate a username and password before authorizing use of the network.
