Introduction

This document describes how to configure Bring Your Own Device (BYOD) on Cisco Identity Services Engine (ISE) for Windows Machine using both Single-SSID and Dual-SSID.

Prerequisites

Requirements

Cisco recommends that you have knowledge of these topics:

- Configuration of Cisco ISE Versions 3.0

- Configuration of Cisco WLC

- BYOD Working

Components Used

The information in this document is based on these software and hardware versions:

- Cisco ISE Version 3.0

- Windows 10

- WLC and AP

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

Theory

In Single SSID BYOD only one SSID is used for both onboardings of devices and later giving full access to the Registered Devices. First, the user connects to the SSID using the user name and password ( MSCHAPv2 ). Once authenticated successfully on ISE, the user gets redirected to the BYOD Portal. Once the Device Registration is done, the end-client downloads the Native Supplicant  Assistant (NSA) from ISE . NSA is installed on the end client and downloads the Profile and certificate from ISE. The NSA configures the Wireless supplicant and the client installs the certificate. Endpoint performs another authentication to the same SSID using the downloaded certificate using EAP-TLS. ISE checks the new request from the client and verifies the EAP Method and Device Registration and gives full access to the device.

Windows BYOD Single SSID Steps-

- Initial EAP-MSCHAPv2 authentication

- Redirection to BYOD portal

- Device registration

- NSA download

- Profile download

- Certificate download

- EAP-TLS Authentication

Configure

ISE Configuration

Step 1. Add network Device on ISE and configure RADIUS and shared key.

Navigate to ISE > Administration > Network Devices > Add Network Device.

Step 2. Create a certificate template for BYOD users. The template must have Client Authentication Enhanced Key Usage. You can use the default EAP_Certificate_Template.

Step 3. Create a Native Supplicant Profile for a Wireless profile.

Navigate to ISE > Work Centres > BYOD > Client Provisioning. Click on Add and choose Native Supplicant Profile (NSP)  from the drop-down.

Here the SSID name must be the same as you connected before you are doing a single SSID BYOD. Select the Protocol as TLS. Chose Certificate template as created in the previous step or you can use the default EAP_Certificate_Template .

Under optional settings select user or User and Machine authentication as per your requirement. In this example, it is configured as user authentication. Leave other settings as default.

Step 4. Create Client Provisioning Policy for Windows Device.

Navigate to ISE > Work Centres > BYOD > Client Provisioning > Client Provisioning Policy . Select the Operating System as Windows ALL. Select WinSPWizard 3.0.0.2 and NSP created in the previous step.

Step 5. Create an Authorization Profile for devices not registered as BYOD devices.

Navigate to ISE > Policy > Policy Elements > Results> Authorization > Authorization Profiles > Add.

Under Common Task, select Native Supplicant Provisioning. Define a Redirect ACL Name that is created on WLC and select the BYOD Portal. Here Default Portal is used. You can create a custom BYOD Portal. Navigate to ISE > Work Centres > BYOD > Portals and components and click on Add.

Step 6. Create a certificate profile.

Navigate to ISE > Administration > External Identity Sources > Certificate Profile. Here create a new certificate profile or use the default certificate profile.

Step 7. Create an identity source sequence and select the certificate profile created in the previous step or use the default certificate profile. This is required when users perform EAP-TLS after BYOD registration to get full access.

Step 8. Create a Policy Set, authentication Policy, and Authorization Policy.

Navigate to ISE > Policy > Policy Sets. Create a Policy Set and Save.

Create an Authentication Policy and select the identity source sequence created in the previous step.

Create an Authorization Policy. You must create two policies.

1. For devices that are not BYOD Registered. Give redirect profile created in step 5.

2. Devices that are BYOD registered and doing EAP-TLS. Give full access to these devices.

WLC Configuration

Step 1. Configure Radius Server on WLC.

Navigate to Security > AAA > Radius > Authentication.

Navigate to Security > AAA > Radius > Accounting.

Step 2. Configure a Dot1x SSID.

Step 3. Configure Redirect ACL to provide limited access for provisioning the device.

- Permit UDP traffic to DHCP and DNS (DHCP is allowed by default).

- Communication to ISE.

- Deny other traffic.

Name: BYOD-Initial (OR whatever you manually named the ACL in the Authorization Profile)

Verify

Authentication Flow Verification

1. At first log in, user performs PEAP authentication using a username and password. On ISE, user hits the Redirect Rule BYOD-Redirect.

2. After the BYOD Registration, user is added to the Registered Device and now performs EAP-TLS and gets Full Access.

Check the My Devices Portal

Navigate to MyDevices Portal and Log In with the credentials.  You can see the device name and the Registration status.

You can create a URL for the MyDevices Portal.

Navigate to ISE > Work Centres > BYOD > Portal and Components > My Devices Portal > Login Settings and then Enter the Fully Qualified URL.

Troubleshoot

General Information

For BYOD process, these ISE components have to be enabled in debug on PSN nodes -

scep- scep log messages. Target log filesguest.log and ise-psc.log.

client-webapp– the component responsible for infrastructure messages. Target log file –ise-psc.log

portal-web-action- the component responsible for client provisioning policy processing. Target log file -guest.log.

portal- all Portal related events. Target log file -guest.log

portal-session-manager -Target log files - Portal session related debug messages - gues.log

ca-service- ca-service messages -Target log files -caservice.log and caservice-misc.log

ca-service-cert- ca-service certificate messages - Target log files - caservice.log and caservice-misc.log

admin-ca- ca-service admin messages -Target log files ise-psc.log, caservice.log and casrvice-misc.log

certprovisioningportal- certificate provisioning portal messages -Target log files ise-psc.log

nsf- NSF related messages -Target log files ise-psc.log

nsf-session- Session cache-related messages -Target log files ise-psc.log

runtime-AAA– All Runtime events. Target log file –prrt-server.log.

For the client-side logs :

Look for %temp%\spwProfileLog.txt (ex: C:\Users\<username>\AppData\Local\Temp\spwProfileLog.txt)
