Overview

RADIUS is a distributed client/server system that assists in securing networks against unauthorized access, allowing a number of communication servers and clients to authenticate users identity through a central database. The database within the RADIUS server stores client information, user information, password, and access privileges, including the use of "shared secret."

RADIUS is a fully open and standard protocol, defined by RFCs (Authentication: 2865, accounting 2866). In the 8000 series switch, you use RADIUS authentication to secure access to the switch (console/Telnet/SSH), and RADIUS accounting to track the management sessions (CLI only).

RADIUS authentication allows the remote server to authenticate logins. RADIUS accounting logs all of the activity of each remote user in a session on the centralized RADIUS accounting server.
