Once you have added the RADIUS server profiles, specify the default primary RADIUS server and secondary RADIUS server to be used in the event of a primary server failure. These servers are used for authentication unless you specify other RADIUS servers in the SSID Configuration, Device Model or Global Model Configuration views, or by mapping RADIUS servers to domains. The default servers are also used for web-portal authentication, when it is configured for RADIUS.
You may want to deploy multiple RADIUS servers to handle requests if the primary server should fail. Within the FortiNAC managed environment, you can define many servers, and you have the option to choose different servers, both a primary and a secondary, for each device.
The first RADIUS server added is the default for the primary RADIUS server until it is changed manually.
- Click System > Settings.
- Expand the Authentication folder and click RADIUS.
The RADIUS server defaults and RADIUS domain mappings windows display.
- In the RADIUS server defaults window select the default primary and secondary server names from the drop-down lists.
- Click Apply to save your changes.
