Product Support

This document does not cover the steps involved in converting

autonomous APs to Lightweight mode such that they can be

controlled by the Cisco WLCs.

Please contact Cisco's Customer Support at www.cisco.com for

instructions on this procedure. Once the APs are converted, this

document can be used to provision APs.

This document does not cover the steps involved to configure a

RADIUS server required for using WPA2-Enterprise or Cisco FSR

security types.

1. Installation and configuration guides for Cisco Wireless LAN

Controllers can be found on Cisco’s website.

2. To convert the Cisco 1200 Series Autonomous AP to Lightweight

mode, go to:

version/lwapp/upgrade/guide/lwapnote.html

3. For more information on the APs in Lightweight mode, see Cisco

Protocol [Cisco Aironet 1130 AG Series] and Cisco Aironet Access

Point Support for Lightweight Access Point Protocol [Cisco

Aironet 1240 AG Series].

This configuration is not applicable to all customer environments.

Configuring a New Controller Starting from Factory Defaults

1. Initial provisioning of the controller is done via the command line

interface (CLI). Connect a null modem serial cable between the

console port of the controller and the serial port of a PC.

2. Open a terminal program, such as Hyper Terminal, and configure the

port settings to 9600 baud, no parity, 8 data bits and 1 stop bit.

VIEW Certified Configuration Guide

PN: 1725-36192-001_H

3. Power-on the controller. Status of the controller’s boot process will

appear as the controller is powering up. Once the controller is

running, it will prompt you to run the Startup Wizard.

4. The Startup Wizard provides for an easy means to perform initial

controller setup and provisioning. Refer to the Installation and Startup

Guide for the Cisco 4400 Series WLC, or other appropriate controller,

found at Cisco’s website. This document contains a detailed

explanation of using the Startup Wizard for the 4400:

http://www.cisco.com/en/US/docs/wireless/controller/4400/quic

k/guide/ctrlv32.html#wp34023

5. Once the controller has been configured via the Startup Wizard, the

remaining configuration can be configured through the switch-web

interface using a Web browser (Cisco recommends using MS IE 6.0+).

6. If necessary, the controller can be reset to factory defaults. To reset

the WLC to factory default, you must reboot, then type Recover-

config at the CLI. This only works before the first time a user logs in

via the console.

Connecting to the Controller Via a Browser

1. Connect to the WLC by pointing your internet browser to the URL:

https<IP_Addr> (where <IP_Addr> is the IP address of the

management interface of the WLC).

2. Click the Login prompt. The default User Name and Password is

admin.

3. Once logged in properly, a page similar to the one below displays.

PN: 1725-36192-001_H 9

Installing Software

1. Make sure that the correct version of software, listed in the Product

Summary, is installed on the controller. From the main menu, click

Monitor.

2. In the navigation pane, click Summary. The heading labeled Software

Version shows the current software version.

3. Download the appropriate software for your model of controller from

the Cisco website.

4. Set up a Trivial File Transfer Protocol (TFTP) server running on a PC

to download the file to the controller.

5. Connect to the controller via a Web browser.

6. From the main menu, click Commands.

7. In the navigation pane, click Download File.

8. For File Type, select Code.

9. For TFTP Server, type in the IP Address of the TFTP server.

10. Add the File Path (this is the path in the TFTP server’s root directory

and not the system path where the TFTP server is located) and File

Name of the firmware file to download.

(Note the example simply uses the /designator for the root TFTP

directory.) Point the TFTP server to the code.

11. Allow a few minutes for the download to complete.

12. Reboot the Controller

Controller Setup

The initial setup of the controller is shown below.

VIEW Certified Configuration Guide

PN: 1725-36192-001_H

The setup instructions outlined in this document are for the

configuration shown in the diagram only. Your configuration may

differ, and the appropriate adjustments must be made.

1. From the main menu, click Controller.

2. Set the Ethernet Multicast Mode to Multicast and enter a multicast IP

address that is currently not being used on your network for the

Multicast Group Address.

3. Click the Apply button.

4. Click Save Configuration.

Connecting APs

As the APs are connected to the network, they should automatically

find the controller via the CAPWAP discovery algorithms. The

Dynamic Host Configuration Protocol (DHCP) server will assign each

AP an IP address.

You can configure a DHCP server to run on a remote PC for a small

deployment. However, for large-scale deployments, an enterprise-

grade DHCP server must be used.

The ap-manager and management interfaces’ configuration should

include the DHCP server you have configured. Alternately, you can

configure the DHCP server internally on the controller to hand out

leases to the connected clients. (Note: The WLC’s DHCP server does

not lease addresses to the AP.) The instructions for doing so are

included at the end of this document.

1. From the main menu, click Controller.
