RADIUS Server
RADIUS 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 user name and password before authorizing use of the network.
