Remote Authentication Dial-In User Service (RADIUS)
Your IX20 device supports Remote Authentication Dial-In User Service (RADIUS), a networking
protocol that provides centralized authentication and authorization management for users who
connect to the device. With RADIUS support, the IX20 device acts as a RADIUS client, which sends user
credentials and connection parameters to a RADIUS server over UDP. The RADIUS server then
authenticates the RADIUS client requests and sends back a response message to the device.
When you are using RADIUS authentication, you can have both local users and RADIUS users able to
log in to the device. To use RADIUS authentication, you must set up a RADIUS server that is accessible
by the IX20 device prior to configuration. The process of setting up a RADIUS server varies by the
server environment. An example of a RADIUS server is FreeRADIUS.
