    It will be better if you can check with Cisco for more access.

    Thanks

    Hello 江姣,

    Here are some common troubleshooting steps:

    1. Ensure that there is network connectivity between the Cisco wireless controller and the Windows Server hosting NPS.
    2. Check for any firewall or access control list (ACL) settings that may be blocking communication between the devices. The default ports for RADIUS are UDP 1812 and 1813. Ensure that the firewall on the Cisco wireless controller allows outgoing connections to the NPS server.
    3. Confirm that the shared secret configured on the Cisco wireless controller matches the shared secret configured on the NPS server. The shared secret must be identical on both devices for successful communication.

    Hope this helps!

    Regards,

    Karlie
