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
Aironet Access Point Support for Lightweight Access Point
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.

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.

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.

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.
