Configuring the Radius Server
Remote Authentication Dial-In User Service (Radius) is a client/server protocol and software enabling
remote access servers to communicate with the controller to authenticate users and authorize their
access to the controller managed network. For an overview on the controller’s Radius deployment, see
“Radius Overview” on page 396 .
Setting up Radius on the controller entails the following configuration activities:
●
Defining the Radius Configuration
●
Configuring Radius Authentication and Accounting
●
Configuring Radius Users
●
Configuring Radius User Groups
●
Viewing Radius Accounting Logs
NOTE
For hotspot deployment, Extreme Networks recommends using the controller’s internal Radius server and built-in
user database. This is the easiest setup option and offers a high degree of security and accountability.
Radius Overview
Radius enables centralized management of controller authentication data (usernames and passwords).
When a MU attempts to associate to the Radius supported controller, the controller sends the
authentication request to the Radius server. The communications between the controller and server are
authenticated and encrypted through the use of a shared secret password (not transmitted over the
network).
