6 Access Point Ports and Connectors

The 1602E model access points have external antenna connectors and the LED indictor on the top of

the model, as shown in Figure 1. The 1602I model access points have integrated antennas and do not

have external connectors on the top of the unit; however, they do have the LED indicator on top of

the unit, as shown in Figure 2.

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 7.4.x.x or later to support 1600 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 “Using DHCP Option 43”

section on page 16.

•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.
