I am currently configuring Radius server with Cisco Wireless Controller 5508. Using debug aaa at the CLI, I can see the controller receive radius client message but nothing coming back from the radius server.
For some reason, Wireless Controller 5508 cannot ping the Radius server using CLI. Yet, I can ping the 5508 controller from the Radius server. The Radius server is running Windows 2008 NPS with firewall turned off. There are no antivirus firewall installed on the Radius server. NPS is installed and configured on Windows 2008. Nothing shows up in the NPS log.
