QuestionQ17

Investigate

You have deployed a new HPE Aruba Networking Mobility Controller (MC) and campus APs (CAPs). One WLAN requires 802.1X authentication through HPE Aruba Networking ClearPass Policy Manager (CPPM). When you test a client connection to the WLAN, the test fails. You check ClearPass Access Tracker but find no record of the authentication attempt. A ping from the MC to CPPM succeeds.

What is a suitable next troubleshooting step?

Explanation

A successful ping confirms IP reachability but does not confirm that RADIUS requests are reaching and being accepted by ClearPass. When an expected request is absent from Access Tracker, ClearPass Event Viewer can expose relevant communication or configuration errors, such as an unrecognized network device or shared-secret mismatch, that occur before a normal authentication transaction is recorded.
