The RADIUS settings view allows you to add or modify RADIUS server profiles for individual network devices. For devices using 802.1x, accept the default primary and secondary RADIUS servers or you can select profiles for each device within its Model or Global Model Configuration view. See Model configuration for additional information.
The ability to map a domain name to a RADIUS server profile also functions within the context of 802.1x. It provides RADIUS server selection based on the domain of the authenticating user. Users authenticating from different Microsoft domains can be directed to separate RADIUS servers configured for those domains.
Users authenticating from a domain, can only authenticate via the RADIUS server profile configured for that domain. Multiple RADIUS server profiles can be configured for each domain and searched for the authenticating user. RADIUS servers are searched in order from the top of the list of servers down.
