Introduction

This document describes how to configure Protected Extensible Authentication Protocol (PEAP) with Microsoft Challenge Handshake Authentication Protocol Version 2 (MS-CHAP v2) authentication on a Cisco Converged Access Wireless LAN (WLAN) deployment with the Microsoft Network Policy Server (NPS) as the RADIUS server.

Prerequisites

Requirements

Cisco recommends that you have knowledge of these topics before you attempt the configuration described in this document:

  • Basic Microsoft Windows Version 2008 installation
  • Cisco Converged Access WLAN controller installation

Ensure that these requirements are met before you attempt this configuration:

  • Install the Microsoft Windows Server Version 2008 Operating System (OS) on each of the servers in the test lab.
  • Update all of the service packs.
  • Install the controllers and Lightweight Access Points (LAPs).
  • Configure the latest software updates.

Note: For initial installation and configuration information for the Cisco Converged Access WLAN controllers, refer to the CT5760 Controller and Catalyst 3850 Switch Configuration Example Cisco article.

Components Used

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

  • Cisco 5760 Series WLAN Controller Version 3.3.2 (Next Generation Wiring Closet (NGWC))
  • Cisco 3602 Series LAP
  • Microsoft Windows XP with Intel PROset Supplicant
  • Microsoft Windows Version 2008 Server that runs NPS with Domain Controller Roles
  • Cisco Catalyst 3560 Series Switch

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, make sure that you understand the potential impact of any command.

Background Information

PEAP uses Transport Level Security (TLS) in order to create an encrypted channel between an authenticating PEAP client, such as a wireless laptop, and a PEAP authenticator, such as the Microsoft NPS or any RADIUS server. PEAP does not specify an authentication method but provides additional security for other Extensible Authentication Protocols (EAPs), such as EAP-MS-CHAP v2, that can operate through the TLS-encrypted channel that is provided by PEAP. The PEAP authentication process consists of two main phases.

PEAP Phase One: TLS-Encrypted Channel

The wireless client associates with the Access Point (AP). An IEEE 802.11-based association provides an open system or shared key authentication before a secure association is created between the client and the AP. After the IEEE 802.11-based association is successfully established between the client and the AP, the TLS session is negotiated with the AP.

After authentication is successfully completed between the wireless client and the NPS, the TLS session is negotiated between the client and the NPS. The key that is derived within this negotiation is used in order to encrypt all subsequent communication.

PEAP Phase Two: EAP-Authenticated Communication

EAP communication, which includes EAP negotiation, occurs inside of the TLS channel that is created by PEAP within the first stage of the PEAP authentication process. The NPS authenticates the wireless client with EAP-MS-CHAP v2. The LAP and the controller only forward messages between the wireless client and the RADIUS server. The WLAN Controller (WLC) and the LAP cannot decrypt the messages because the WLC is not the TLS endpoint.

Here is the RADIUS message sequence for a successful authentication attempt, where the user supplies valid password-based credentials with PEAP-MS-CHAP v2:

  1. The NPS sends an identity request message to the client:
    EAP-Request/Identity
  2. The client responds with an identity response message:
    EAP-Response/Identity
  3. The NPS sends an MS-CHAP v2 challenge message:
    EAP-Request/EAP-Type=EAP MS-CHAP-V2 (Challenge)
  4. The client responds with an MS-CHAP v2 challenge and response:
    EAP-Response/EAP-Type=EAP-MS-CHAP-V2 (Response)
  5. The NPS responds with an MS-CHAP v2 success packet when the server successfully authenticates the client:
    EAP-Request/EAP-Type=EAP-MS-CHAP-V2 (Success)
  6. The client responds with an MS-CHAP v2 success packet when the client successfully authenticates the server:
    EAP-Response/EAP-Type=EAP-MS-CHAP-V2 (Success)
  7. The NPS sends an EAP-type-length-value (TLV) that indicates successful authentication.

  8. The client responds with an EAP-TLV status success message.

  9. The server completes authentication and sends an EAP-Success message in plain text. If VLANs are deployed for client isolation, the VLAN attributes are included in this message.

Configure

Use this section in order to configure PEAP with MS-CHAP v2 authentication on a Cisco Converged Access WLC deployment with the Microsoft NPS as the RADIUS server.

Network Diagram

In this example, the Microsoft Windows Version 2008 server performs these roles:

  • Domain controller for the wireless.com domain
  • Domain Name System (DNS) server
  • Certificate Authority (CA) server
  • NPS in order to authenticate the wireless users
  • Active Directory (AD) in order to maintain the user database

The server connects to the wired network through a Layer 2 (L2) switch, as shown. The WLC and the registered LAP also connect to the network through the L2 switch.

The wireless clients use Wi-Fi Protected Access 2 (WPA2) - PEAP-MS-CHAP v2 authentication in order to connect to the wireless network.

Configurations

The configuration that is described in this section is completed in two steps:

  1. Configure the 5760/3850 Series WLC with the CLI or GUI.

  2. Configure the Microsoft Windows Version 2008 server for NPS, Domain Controller, and User Accounts on the AD.

Configure Converged Access WLCs with the CLI

Complete these steps in order to configure the WLAN for the required client VLAN and map it to the Authentication Method List with the CLI:

Note: Ensure that dot1x system auth control is enabled on the WLC, or the dot1X does not work.

  1. Enable the AAA new model feature.

  2. Configure the RADIUS server.

  3. Add the server into the Server Group.

  4. Map the Server Group to the Method List.

  5. Map the Method List to the WLAN.

Troubleshoot

Note: Cisco recommends that you use traces in order to troubleshoot wireless issues. Traces are saved in the circular buffer and are not processor intensive.

Enable these traces in order to obtain the L2 auth logs:

  • set trace group-wireless-secure level debug
  • set trace group-wireless-secure filter mac 0017.7C2F.B69A

Enable these traces in order to obtain the dot1X AAA events:

  • set trace wcm-dot1x aaa level debug
  • set trace wcm-dot1x aaa filter mac 0017.7C2F.B69A

Enable these traces in order to receive the DHCP events:

  • set trace dhcp events level debug
  • set trace dhcp events filter mac 0017.7C2F.B69A

Enable these traces in order to disable the traces and clear the buffer:

  • set trace control sys-filtered-traces clear
  • set trace wcm-dot1x aaa level default
  • set trace wcm-dot1x aaa filter none
  • set trace group-wireless-secure level default
  • set trace group-wireless-secure filter none

Enter the show trace sys-filtered-traces command in order to view the traces:
