It's possible to activate Radius in Guest Access and Captive Portal / Splash Page applications, in order to provide AAA capabilities.
STEPS
- Create an SSID, click on the "Wireless security" tab
- Select "External Splash Page with Radius"
- Fill the following fields: Radius Server Address, Radius Secret, NAS Id

FIELDS
- Radius Server Address: the hostname/IP address of the primary Radius server that will provide AAA;
- Radius Secret: the shared secret that authenticates Classic Hotspot at the Radius server;
- Radius port_acct: accounting port
- Radius port_auth: authentication port
NOTE:
If a radius server is not available, it's possible to start providing Captive Portal / Splash Pages without Radius authentication, and then add Radius Authentication in a second step.
