6-94 Motorola RF Switch System Reference Guide
6.8 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 switch to authenticate users and authorize their access to the
switch managed network. For an overview on the switch’s Radius deployment, see
Radius Overview on page 6-94 .
Setting up Radius on the switch 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
6.8.1 Radius Overview
Radius enables centralized management of switch authentication data (usernames and passwords). When a
MU attempts to associate to the Radius supported switch, the switch sends the authentication request to
the Radius server. The communications between the switch and server are authenticated and encrypted
through the use of a shared secret password (not transmitted over the network).
The switch’s local Radius server stores the authentication data locally, but can also be configured to use a
remote user database. A Radius server as the centralized authentication server is an excellent choice for
performing accounting. Radius can significantly increase security by centralizing password management.
The Radius server defines authentication and authorization schemes for granting the access to wireless
clients. Radius is also used for authenticating hotspot and remote VPN Xauth. The switch can be configured
to use 802.1x EAP for authenticating wireless clients with a Radius server. The following EAP authentication
types are supported by the switch’s onboard Radius server:
• TLS
• TLS and MD5
• TTLS and PAP
• TTLS and MSCHAPv2
• PEAP and GTC
• PEAP and MSCHAPv2
NOTE: For hotspot deployment, Motorola recommends using the switch’s onboard Radius
server and built-in user database. This is the easiest setup option and offers a high
degree of security and accountability.
NOTE: The switch can be configured to use its own local Radius server or an external
Radius server you define and configure. For information on the benefits and risks of using
the switch’s resident Radius Server (as opposed to an external Radius Server), see
Using the Switch’s Radius Server Versus an External Radius on page 6-96 .
CAUTION: When restarting or rebooting the switch, the Radius server is restarted
regardless of its state before the reboot.
