Question Image

You are deploying a new HPE Aruba Networking Mobility Controller (MC) that enforces authentication through HPE Aruba Networking ClearPass Policy Manager (CPPM). Authentication is not functioning correctly, and the CPPM Event Viewer displays the error shown in the exhibit.

What should you verify?

Explanation

An “unknown NAD” RADIUS event means ClearPass cannot associate the incoming RADIUS request with a configured network access device. The Mobility Controller’s source IP address for traffic to ClearPass must therefore match the IP address configured for that device in ClearPass.
