Explanation

The exhibit shows an error in the CPPM Event Viewer: "RADIUS authentication attempt from unknown NAD 10.1.10.8:1812." This indicates that a new HPE Aruba Networking Mobility Controller (MC) is attempting to send RADIUS authentication requests to HPE Aruba Networking ClearPass Policy Manager (CPPM), but CPPM does not recognize the MC as a Network Access Device (NAD), resulting in the authentication failure. Unknown NAD Error: In CPPM, a NAD is a device (e.g., an MC, switch, or AP) that sends RADIUS requests to CPPM for authentication. Each NAD must be configured in CPPM with its IP address and a shared secret. The error "unknown NAD 10.1.10.8:1812" means that the IP address 10.1.10.8 (the source IP of the MC's RADIUS request) is not listed as a NAD in CPPM's configuration, so CPPM rejects the request.
