RADIUS Authenticated SSID

OpenWiFi 2.0

When authenticating clients with back office RADIUS systems, the configuration of OpenWiFi permits this on a per SSID basis.

Many parameters are possible with RADIUS authentications given the many methods in use worldwide. Many of the EAP methods have configuration options described below.

RADIUS Attribute	Description
nas-identifier	Unique NAS Id used with RADIUS server
chargeable-user-id	Chargeable User Entity per RFC4372
local	Local RADIUS within AP device server-identity users - Local EAP users based on username, PreShared Key and VLAN id
authentication	RADIUS server host IP address port ( example 1812) secret ( Shared secret with RADIUS server ) Additional methods within Access-Request request-attribute ( id of RADIUS server ) id ( numeric value of RADIUS server ) value Any sub-value defined as integer RADIUS attribute value
accounting	RADIUS server host IP address port ( example 1813) secret ( Shared secret with RADIUS server ) Additional methods within Access-Request sent in Accounting request-attribute ( id of RADIUS server ) id ( numeric value of RADIUS server ) value Any sub-value defined as integer RADIUS attribute value
accounting	interval ( Interim accounting interval defined in seconds )
