7 Configuring the Access Point

This section describes how to connect the access point to a wireless LAN controller. Because the configuration process takes place on the controller, see the Cisco Wireless LAN Controller Configuration Guide for additional information. This guide is available on Cisco.com.

The Controller Discovery Process

The access point uses standard Control and Provisioning of Wireless Access Points Protocol (CAPWAP) to communicate between the controller and other wireless access points on the network. CAPWAP is a standard, interoperable protocol which enables an access controller to manage a collection of wireless termination points. The discovery process using CAPWAP is identical to the Lightweight Access Point Protocol (LWAPP) used with previous Cisco Aironet access points. LWAPP-enabled access points are compatible with CAPWAP, and conversion to a CAPWAP controller is seamless. Deployments can combine CAPWAP and LWAPP software on the controllers.

The functionality provided by the controller does not change except for customers who have Layer 2 deployments, which CAPWAP does not support.

In a CAPWAP environment, a wireless access point discovers a controller by using CAPWAP discovery mechanisms and then sends it a CAPWAP join request. The controller sends the access point a CAPWAP join response allowing the access point to join the controller. When the access point joins the controller, the controller manages its configuration, firmware, control transactions, and data transactions.

Note For additional information about the discovery process and CAPWAP, see the Cisco Wireless

LAN Controller Software Configuration Guide. This document is available on Cisco.com.

Note CAPWAP support is provided in controller software release 5.2 or later. However, your

controller must be running release 7.1.91.0 or later to support 3600 series access points.

Note You cannot edit or query any access point using the controller CLI if the name of the access

point contains a space.

Note Make sure that the controller is set to the current time. If the controller is set to a time that

has already occurred, the access point might not join the controller because its certificate may not be valid for that time.

Access points must be discovered by a controller before they can become an active part of the network. The access point supports these controller discovery processes:

• Layer 3 CAPWAP discovery—Can occur on different subnets than the access point and uses IP addresses and UDP packets rather than MAC addresses used by Layer 2 discovery.

• Locally stored controller IP address discovery—If the access point was previously joined to a controller, the IP addresses of the primary, secondary, and tertiary controllers are stored in the access point’s non-volatile memory. This process of storing controller IP addresses on an access point for later deployment is called priming the access point. For more information about priming, see the “Performing a Pre-Installation Configuration” section on page 11.

• DHCP server discovery—This feature uses DHCP option 43 to provide controller IP addresses to the access points. Cisco switches support a DHCP server option that is typically used for this capability. For more information about DHCP option 43, see the “Configuring DHCP Option 43 and DHCP Option 60” section on page 37.

• DNS discovery—The access point can discover controllers through your domain name server (DNS). For the access point to do so, you must configure your DNS to return controller IP addresses in response to CISCO-CAPWAP-CONTROLLER.localdomain, where localdomain is the access point domain name. Configuring the CISCO-CAPWAP-CONTROLLER provides backwards compatibility in an existing customer deployment. When an access point receives an IP address and DNS information from a DHCP server, it contacts the DNS to resolve CISCO-CAPWAP-CONTROLLER.localdomain. When the DNS sends a list of controller IP addresses, the access point sends discovery requests to the controllers.

Preparing the Access Point

Before you mount and deploy your access point, we recommend that you perform a site survey (or use the site planning tool) to determine the best location to install your access point.

You should have the following information about your wireless network available:

• Access point locations.

• Access point mounting options: below a suspended ceiling, on a flat horizontal surface, or on a

desktop.

Note You can mount the access point above a suspended ceiling but you must purchase

additional mounting hardware: See “Mounting the Access Point” section on page 15 for additional information.

• Access point power options: power supplied by the recommended external power supply (Cisco AIR-PWR-B), a DC power supply, PoE from a network device, or a PoE power injector/hub (usually located in a wiring closet).

Note Access points mounted in a building’s environmental airspace must be powered using PoE

to comply with safety regulations.

Cisco recommends that you make a site map showing access point locations so that you can record the device MAC addresses from each location and return them to the person who is planning or managing your wireless network.

Installation Summary

Installing the access point involves these operations:

• Performing a pre-installation configuration (optional)

• Mounting the access point

• Grounding the access point

• Deploying the access point on the wireless network

Performing a Pre-Installation Configuration

The following procedures ensure that your access point installation and initial operation go as expected. A pre-installation configuration is also known as priming the access point. This procedure is optional.

Note Performing a pre-installation configuration is an optional procedure. If your network

controller is properly configured, you can install your access point in its final location and connect it to the network from there. See the “Deploying the Access Point on the Wireless

Network” section on page 15 for details.

Pre-Installation Configuration Setup

The pre-installation configuration setup is shown in Figure 4.

To perform pre-installation configuration, perform the following steps:

Step 1 Make sure that the Cisco wireless LAN controller DS port is connected to the network. Use

the CLI, web-browser interface, or Cisco WCS procedures as described in the appropriate Cisco wireless LAN controller guide.

a. Make sure that access points have Layer 3 connectivity to the Cisco wireless LAN controller

Management and AP-Manager Interface.

b. Configure the switch to which your access point is to attach. See the Cisco Wireless LAN

Controller Configuration Guide, Release x.x for additional information.

c. Set the Cisco wireless LAN controller as the master so that new access points always join with

it.

d. Make sure DHCP is enabled on the network. The access point must receive its IP address

through DHCP.
