Explanation
Given the error message from the ClearPass Policy Manager (CPPM) Event Viewer, indicating a RADIUS authentication attempt from an unknown Network Access Device (NAD), you should check that the IP address the Mobility Controller (MC) is using to communicate with CPPM matches the IP address defined for the MC in the CPPM's device inventory. If there is a mismatch in IP addresses, CPPM will not recognize the MC as a known device and will not process the authentication request, leading to the error observed.
