1 CONFIDENTIAL © Copyright Aruba Networks, Inc. All rights reserved AOS & CPPM INTEGRATION CONFIGURATION & TESTING EAP TLS & EAP PEAP by Abilash Soundararajan

2 EAP-TLS CONFIDENTIAL © Copyright Aruba Networks, Inc. All rights reserved

3 Certificate Requirements for EAP-TLS architecture (EAP tunnel termination on CPPM) User Certificate Root CA Cert Radius CA Cert Signing CA Cert Root CA in Trusted Root CA list

4 Certificate Requirements for EAP-TLS architecture (EAP tunnel termination on Controller) User Certificate Server Cert Trusted CA Cert Root CA Cert Signing CA Cert Root CA in Trusted Root CA list

5 SETTING UP EAP-TLS TERMINATION ON CPPM CONFIDENTIAL © Copyright Aruba Networks, Inc. All rights reserved

6 Steps for EAP-TLS (Termination on CPPM) Creating CA & Signing CA on CPPM Configuring Controller –SSID profile –Dot1x 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

7 Creating CA & Signing CA on CPPM CONFIDENTIAL © Copyright Aruba Networks, Inc. All rights reserved

8 Creating CA & Signing CA on CPPM CONFIDENTIAL © Copyright Aruba Networks, Inc. All rights reserved

9 Checking CA cert info CONFIDENTIAL © Copyright Aruba Networks, Inc. All rights reserved

10 Configuring Controller – SSID profile CONFIDENTIAL © Copyright Aruba Networks, Inc. All rights reserved

11 Configuring Controller – Dot1x profile CONFIDENTIAL © Copyright Aruba Networks, Inc. All rights reserved

12 Configure server info and map to server group CONFIDENTIAL © Copyright Aruba Networks, Inc. All rights reserved

13 Mapping Dot1x, AAA & SSID profiles CONFIDENTIAL © Copyright Aruba Networks, Inc. All rights reserved Mapping Do1x to AAA profile Mapping AAA & SSID to VAP Profile Add this VAP to the AP-group that needs this SSID.

14 Add Controller to the devices in CPPM CONFIDENTIAL © Copyright Aruba Networks, Inc. All rights reserved

15 Creating an Enforcement Policy CONFIDENTIAL © Copyright Aruba Networks, Inc. All rights reserved

16 Creating Enforcement Policy Rules CONFIDENTIAL © Copyright Aruba Networks, Inc. All rights reserved There are different ways of doing this step. In this case we are going to check, if the Certificate submitted by client for authentication has in its common name “Company_ABCD”, which is also in our list of Signing CAs.

17 Creating Service in CPPM to cater to EAP-TLS requests CONFIDENTIAL © Copyright Aruba Networks, Inc. All rights reserved Adding ESSID name to the list of conditions to be checked to match this Service.

18 Adding necessary Authentication Methods & Sources necessary CONFIDENTIAL © Copyright Aruba Networks, Inc. All rights reserved

19 Mapping the Enforcement Profile configured CONFIDENTIAL © Copyright Aruba Networks, Inc. All rights reserved

20 Creating CSR for RADIUS server CONFIDENTIAL © Copyright Aruba Networks, Inc. All rights reserved Note: Need to download 2 files. “CertSignRequest.csr” & “CertPrivKey.pkey”

21 Creating Radius server cert with corresponding CA CONFIDENTIAL © Copyright Aruba Networks, Inc. All rights reserved

22 Uploading the Radius server cert to Server Certs CONFIDENTIAL © Copyright Aruba Networks, Inc. All rights reserved

23 New Radius certificate seen in the Server Certs CONFIDENTIAL © Copyright Aruba Networks, Inc. All rights reserved

24 Creating User certificates CONFIDENTIAL © Copyright Aruba Networks, Inc. All rights reserved

25 Checking Certificates created and Exporting Client certificate CONFIDENTIAL © Copyright Aruba Networks, Inc. All rights reserved Exporting Client Certificate with private key, secured with a Passphrase

68 MISCELLANEOUS TROUBLESHOOTING TIPS CONFIDENTIAL © Copyright Aruba Networks, Inc. All rights reserved

69 Check the service that is being used in case failed authentication In the below output for some reason its hitting wrong Service “test123”, while name of our service is “Company_ABCD-EAP-PEAP”

70 Check if right Authentication methods are configured CONFIDENTIAL © Copyright Aruba Networks, Inc. All rights reserved In the below output only “Mschap” was configured as the Authentication method, while actually “EAP-PEAP” was required.

71 Ensure right certificates are used at CPPM, Controller & Client CONFIDENTIAL © Copyright Aruba Networks, Inc. All rights reserved 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.
