This Cisco ISE BYOD mini video series demonstrates device onboarding process for users to connect their personal devices to a corporate network as part of Bring Your Own Device (BYOD) concept. We will be covering both wired and wireless access using Windows 7, iPhone, and Android as client devices. Relevant authentication, authorization, and client provisioning policies will be presented. We will also looks at how users can manage their own devices through the My Devices Portal.

In part 5, we test onboarding process to verify our configuration completed in part 4 using Windows 7, iPhone, and Android devices.
Topic:
  • SCEP CA Profile
  • Device Registration
  • Policy Element Condition
    • Authorization (Compound Condition)
  • Policy Element Result
    • Authorization (Authorization Profile)
      • Web Authentication (Supplicant Provisioning)
      • Airspace ACL
    • Client Provisioning (Native Supplicant Profile)
  • Authentication Policy
  • Authorization Policy
  • Client Provisioning Policy
  • My Devices Portal
  • Device Blacklist
Notes:
  • SSID 1: Onboarding SSID with Open authentication (MAC Filtering)
  • SSID 2: Internal SSID with WPA Enterprise (potentially hidden)
  • Users authenticate through wireless MAB to register device and download profile
  • Users authenticate through EAP-TLS to gain network access
  • ISE acts as SCEP proxy and request certificate on user behalf with the following attributes
    • CN = Username used in authentication
    • Subject Alternative Name = Client MAC address

Hello everyone and thanks for the videos.
My installation works very good for the onboarding process for android and windows desktop devices, but I can't onboard the apple devices.
When I start the process on my iphone, the onboarding page come and disappears immediatly taking me to the ca certificate install page and after I install the certificate I'm not redirected to the onboarding page and if I try to surf the web, I get captured again from the captive portal and again the ca certificate installation is prompted to me.
This is endless.

Have you the same problem? May be something changed apple side with the last os update? I tested the procedure with ios 6.0.2 and 6.1.3

Thanks and best regards

Can you provide more info if you do single or dual SSID, were you able to register device MAC address, was there any error message on the log (both live authorization and client provisioning), and did you setup client provisioning policy for ios device? Since you already got it working with other devices, obviously it has to be ios-related setup.

Thanks for you reply.
I'm using a single SSID.
No error message in the log here:

the provisioning policy is exactly lyke your video, I have one policy for Android and Apple iOS All
and with result the WLAN-TLS Native Supplicant Profile.

thanks for your support

It looks like the PEAP authentication was successful so I would assume that you get the page to register device MAC address when open a browser at this point. So what happen after once you register the device, did you get as far as installing the profile and seeing the key being generated on iPhone?

Submitted by Pepa on Wed, 07/17/2013 - 08:04

I uploaded a video so you can see what really happen to my iphone

It looks like the iphone pseudo-browser is interfering. Make sure you enable captive bypass on the WLC. Please see the video below for more detail starting aroung minutes 5.

Thanks for your support, this seems to be the solution to my problem.
I will check if this option will cause some problem to my users.

It is very difficult to find someone expert on this product, do you sell consultant support to help me in configuring in a perfect manner WLC and ISE?

Thanks again

You are welcome. Let us know how this works out for you. Due to our limited resource, we cannot offer consulting service but feel free to post additional questions.

Hi,

My name is José Luis Castro

Please, do you help me ?

I don`t speak english.

I have ISE 1.2

I have two SSID: VIP (172.20.179.X) and FUNCIONARIOS (172.20.176.X)

I have two groups in Active Directory: Administradores and Empleados

I want to make settings in the ISE so that when a user chooses the SSID: VIP and this belongs to the Administrators group can access or connect to the network without any problems otherwise not be able to connect, forcing the user to choose the SSID: FUNCIONARIOS

I think is create a rule only when users choose the SSID: VIP

I don`t know if this can be set in the ISE.

Submitted by admin on Sat, 05/30/2015 - 06:24

You need to create two rules on auth policy matcing by SSID (RADIUS called-station-id) and AD external user group and assign appropriate auth profile. You can see our ISE 1.3 802.1x wireless authentication for more detail.
