212 CyberSWITCH
The Remote Authentication Dial-In User Service (RADIUS) is a central database supported by the
CyberSWITCH. RADIUS operates using two components: an authentication server and client
protocols. The RADIUS Server software is typically installed on a UNIX-based or NT-based system
that is local to the network. The client protocols allow the CyberSWITCH to communicate with the
RADIUS server, ultimately authenticating devices.

When enabled and properly configured, the CyberSWITCH software implements the RADIUS
client. The RADIUS client sends packets to the RADIUS Authentication Server. These packets
support the following attributes:

The following is a typical scenario if the RADIUS Server is activated: when a remote device needs
to be authenticated, the system will send an access request to the primary RADIUS Server. After
the configured time interval the system will send an access request retry if the primary server does
not respond. After the configured number of retries, the system will request authentication
information from the secondary server if one is configured. The connection will be released if
neither server responds to the access requests.

information required for each type of remote device. The information you need to configure
depends upon what you have configured for the CyberSWITCH operating mode (bridging and/or
routing), and the security options you select.
