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?

  • A that the MC has been added as a domain machine on the Active Directory domain with which CPPM is synchronized
  • B that the MC has valid admin credentials configured on it for logging into the CPPM
  • C that the IP address that the MC is using to reach CPPM matches the one defined for the device on CPPM
  • D that the shared secret configured for the CPPM authentication server matches the one defined for the device on CPPM
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.
