Unified Access Wireless LAN Controllers Guest Anchor with Converged Access Configuration Example

Introduction

This documents describes how to configure the 5508/5760 Series Wireless LAN Controllers (WLCs) and the Catalyst 3850 Series Switch for the wireless client Guest Anchor in the new mobility deployment setup where the 5508 Series WLC acts as the Mobility Anchor and the Catalyst 3850 Series Switch acts as a Mobility Foreign Controller for the clients. Additionally, the Catalyst 3850 Series Switch acts as a Mobility Agent to a 5760 Series WLC that acts as a Mobility Controller from where the Catalyst 3850 Series Switch acquires the Access Point (AP) license.

Prerequisites

Requirements

Cisco recommends that you have knowledge of these topics before you attempt this configuration:

• Cisco IOS^® GUI or CLI with the Converged Access 5760 and 3650 Series WLCs and the Catalyst 3850 Series Switch
• GUI and CLI access with the 5508 Series WLC
• Service Set Identifier (SSID) configuration
• Web authentication

Components Used

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

• Cisco 5760 Release 3.3.3 (Next Generation Wiring Closet [NGWC])
• Catalyst 3850 Series Switch
• Cisco 5508 Series WLC Release 7.6.120
• Cisco 3602 Series Lightweight APs
• Cisco Catalyst 3560 Series Switches

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.

Configure

Note: Use the Command Lookup Tool (registered customers only) in order to obtain more information on the commands used in this section.

Network Diagram

The 5508 Series WLC acts as an Anchor Controller, and the Catalyst 3850 Series Switch acts as a Foreign Controller and the Mobility Agent that obtains the license from the Mobility Controller 5760.

Note: In the network diagram, the 5508 Series WLC acts as the Anchor Controller, the 5760 Series WLC acts as the Mobility Controller, and the Catalyst 3850 Series Switch acts as the Mobility Agent and Foreign WLC. At any point in time, the Anchor Controller for the Catalyst 3850 Series Switch is either the 5760 Series WLC or the 5508 Series WLC. Both cannot be Anchors at the same time, because the double anchor does not work.

Configurations

The configuration includes three parts:

Part 1 - Configuration on the 5508 Anchor WLC

Part 2 - Converged Access Mobility Configuration between the 5508/5760 Series WLC and the Catalyst 3850 Series Switch

Part 3 - Configuration on the Foreign Catalyst 3850 Series Switch

Part 1 - Configuration on the 5508 Anchor WLC

1. On the 5508 Series WLC, hover over WLAN > New in order to create a new Wireless LAN (WLAN).
   
   

   

   
   
   
2. Hover over WLAN > WLAN Edit > Security > Layer 3 enabled Web-authentication in order to configure Layer 3 Security.
   
   

   

   
   
   
3. Make the Anchor address local under the WLAN mobility Anchor configuration window in order to add the 5508 Series WLC as the Anchor.
   

   

   
   
   
4. Hover over Security > Webauth > Webauth page in order to configure the Webauth page to be used for the client authentication.
   
   In this example, the WLC Internal Webauth page is selected:
   
   

   

   
   
   
5. Create a local net user. This username/password pair is used by the user when prompted on the Webauth page.
   
   

   

Part 2 -Converged Access Mobility Configuration between the 5508/5760 Series WLC and the Catalyst 3850 Series Switch

1. On the 5508 Series WLC, add the 5760 Series WLC as the Mobility Peer.
   
   

   

   
   
   
2. On the 5760 Series WLC, acting as a Mobility Controller, add the 5508 Series WLC as the Mobility Peer.
   
   

   

   
   
   
3. This step is very important! Add the Catalyst 3850 Series Switch as the Mobility Agent on the 5760 Series WLC under the Switch Peer Group tab under Mobility Management.
   
   

   

   
   
   
4. On the Catalyst 3850 Series Switch, add the 5760 Series WLC as the Mobility Controller. Once you do this, the Catalyst 3850 Series Switch grabs the AP coult license from the Mobility Controller 5760.
   
   

   

Part 3: Configuration on the Foreign Catalyst 3850 Series Switch

1. Hover over GUI > Configuration > Wireless > WLAN > New in order to configure the Exact SSID/WLAN on the Catalyst 3850 Series Switch.
   
   

   

   
   
   
2. Hover over WLAN > WLAN Edit > Security > Layer 3 enabled Web-authentication in order to configure Layer 3 Security.
   
   

   

   
   
   
3. Add the 5508 Series WLC IP address as the Anchor under the WLAN Mobility Anchor configuration
   
   

   

Verify

Use this section in order to confirm that your configuration works properly.

Connect the client to the WLAN Cisco Unified Wireless Network (CUWN). Here is the work flow:

1. The client receives an IP address.
2. The client opens a browser and accesses any website.
3. The first TCP packet sent by the client is hijacked by the WLC, and the WLC intercepts and sends the Webauth page.
4. If the DNS is properly configured, the client gets the Webauth page.
5. The client must provide the username/password in order to get authenticated.
6. After sucessful authentication, the client is redirected to the original access page.
   
   

   

7. After the client provides the right credentials, the client passes the auth.
   
   

   

Troubleshoot

In order to troubleshoot your configuration, enter these debugs on the 5508 Series WLC, which acts as a Guest Anchor:

Debug Client <client mac addr>
Debug web-auth redirect enable mac <client mac addr>

Here is an example:

Debug Client 00:17:7C:2F:B6:9A
Debug web-auth redirect enable mac 00:17:7C:2F:B6:9A

show debug 

MAC Addr 1.................................. 00:17:7C:2F:B6:9A

Here is the client-side packet capture.
