Steps for EAP-TLS (Termination on CPPM) • Creating CA & Signing CA on CPPM • Configuring Controller – SSID profile – Dot 1 x profile – Server & Server Group – AAA profile – VAP Profile – Mapping to AP-group • • • Configuring Device & Services in CPPM Creating CSR, Radius cert and uploading it Creating User in CPPM Creating Client Certificates Checking Access Tracker Troubleshooting from Controller

Mapping Dot 1 x, AAA & SSID profiles Mapping Do 1 x to AAA profile Mapping AAA & SSID to VAP Profile Add this VAP to the AP-group that needs this SSID. CONFIDENTIAL © Copyright 2014. Aruba Networks, Inc. All rights reserved

Ensure right certificates are used at CPPM, Controller & Client Always ensure • The certificate path is correct and right certificates are positioned in right devices. • The root CA is trusted in the client device • Validate the server certificate in client for mutual authentication & mention the exact CN of the Authentication server.
