Configuring RADIUS Attribute for ClearPass Policy Manager Server Load Balancing
The administrators can configure a RADIUS server IP address as one of the parameters on
ClearPass Policy Manager server for external captive portal user authentication. Configuring
a RADIUS server attribute for guest user authentication allows the administrators to balance
the load on the ClearPass Policy Manager servers.
When the RADIUS server IP address is configured under Extra Fields in the ClearPass
Guest login page, the RADIUS server IP parameter is submitted to the server as part of the
HTTP or HTTPS POST data when the guest users initiate an HTTP or HTTPS request. The
AP intercepts this information to perform the actual RADIUS authentication with the server IP
defined in the POST message. For more information on guest registration customization on
ClearPass Guest, refer to the
