5 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 3502P access point uses the IETF 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 7.0.116.0 or later to support 3502P 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.
ap3502getstartForJMR3.fm Page 8 Thursday, October 27, 2011 11:28 AM
Access points must be discovered by a controller before they can become an active part of the network.
The 3502P 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.
• Over-the-air provisioning (OTAP)—This feature is supported by Cisco 4400 series controllers. If
this feature is enabled on the controller, all joined access points transmit wireless CAPWAP
neighbor messages, and new access points receive the controller IP address from these messages.
This feature is disabled by default and should remain disabled when all access points are installed.
Additional information about OTAP is available on Cisco.com at the following link:
http://www.ciscosystems.com/en/US/products/ps6366/products_tech_note09186a008093d74a.shtml
• 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 9.
• 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 27.
• 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-LWAPP-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.
ap3502getstartForJMR3.fm Page 9 Thursday, October 27, 2011 11:28 AM
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 13 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 13 for details.

access points
Follow these steps to perform the pre-installation configuration.
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 Unified Wireless
Network WLAN Controller Guide: Cisco 440x Series WLAN Controllers 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.
10
ap3502getstartForJMR3.fm Page 11 Thursday, October 27, 2011 11:28 AM
e. CAPWAP UDP ports must not be blocked in the network.
f. The access point must be able to find the IP address of the controller. This can be
accomplished using DHCP, DNS, or IP subnet broadcast. This guide describes the DHCP
method to convey the controller IP address. For other methods, refer to the product
documentation. See also the “Using DHCP Option 43” section on page 14 for more
information.
Step 2
Apply power to the access point:
a. The access point is 802.3af (15.4 W) compliant and can be powered by any of the following
802.3af compliant devices:
– 2106 controller
– WS-C3550, WS-C3560, and WS-C3750 switches
– C1880 switch
– 2600, 2610, 2611, 2621, 2650, and 2651 multiservice platforms
– 2610XM, 2611XM, 2621XM, 2650XM, 2651XM, and 2691 multiservice platforms
– 2811, 2821, and 2851 integrated services routers
– 3620, 3631-telco, 3640, and 3660 multiservice platforms
– 3725 and 3745 multiservice access routers
– 3825 and 3845 integrated services routers
The recommended external power supply for the access point is the Cisco AIR-PWR-B
power supply. The access point can also be powered by the following optional external
power sources:
– 1250 series access point power injector (AIR-PWRINJ4)
– Any 802.3af compliant power injector
Note
The 3502P access point requires a Gigibit Ethernet link to prevent the Ethernet port
from becoming a bottleneck for traffic because wireless traffic speeds exceed transmit
speeds of a 10/100 Ethernet port.
b. As the access point attempts to connect to the controller, the LEDs cycle through a green, red,
and amber sequence, which can take up to 5 minutes.
Note
If the access point remains in this mode for more than five minutes, the access point is
unable to find the Master Cisco wireless LAN controller. Check the connection between
the access point and the Cisco wireless LAN controller and be sure that they are on the
same subnet.
11
ap3502getstartForJMR3.fm Page 12 Thursday, October 27, 2011 11:28 AM
c. If the access point shuts down, check the power source.
d. After the access point finds the Cisco wireless LAN controller, it attempts to download the
new operating system code if the access point code version differs from the Cisco wireless
LAN controller code version. While this is happening, the Status LED blinks dark blue.
e. If the operating system download is successful, the access point reboots.
Step 3
Configure the access point if required. Use the controller CLI, controller GUI, or Cisco WCS
to customize the access-point-specific 802.11n network settings.
Step 4
If the pre-installation configuration is successful, the Status LED is green indicating normal
operation. Disconnect the access point and mount it at the location at which you intend to
deploy it on the wireless network.
Step 5
If your access point does not indicate normal operation, turn it off and repeat the
pre-installation configuration.
Note
12
When you are installing a Layer 3 access point on a different subnet than the Cisco
wireless LAN controller, be sure that a DHCP server is reachable from the subnet on
which you will be installing the access point, and that the subnet has a route back to
the Cisco wireless LAN controller. Also be sure that the route back to the Cisco
wireless LAN controller has destination UDP ports 5246 and 5247 open for CAPWAP
communications. Ensure that the route back to the primary, secondary, and tertiary
wireless LAN controller allows IP packet fragments. Finally, be sure that if address
translation is used, that the access point and the Cisco wireless LAN controller have
a static 1-to-1 NAT to an outside address. (Port Address Translation is not
supported.)
ap3502getstartForJMR3.fm Page 13 Thursday, October 27, 2011 11:28 AM
6 Mounting the Access Point
Cisco Aironet 3502P access points can be mounted in several configurations, including on a suspended
ceiling, on a hard ceiling or wall, on an elecrtical or network box, and above a suspended ceiling.
However, because of the concentrated transmit power from the unit’s external antennas, only trained,
professional installers should install the 3502P and its antennas.
Warning
Only trained and qualified personnel should be allowed to install, replace, or service this
equipment.

7 Deploying the Access Point on the Wireless Network
After you have mounted the access point, follow these steps to deploy it on the wireless network.
Step 1
Connect and power up the access point.
Step 2
Observe the access point LED.
a. When you power up the access point, it begins a power-up sequence that you can verify by
observing the access point LED. If the power-up sequence is successful, the discovery and join
process begins. During this process, the LED blinks sequentially green, red, and off. When the
access point has joined a controller, the LED is green if no clients are associated or blue if one
or more clients are associated.
b. If the LED is not on, the access point is most likely not receiving power.
c. If the LED blinks sequentially for more than 5 minutes, the access point is unable to find its
primary, secondary, and tertiary Cisco wireless LAN controller. Check the connection
between the access point and the Cisco wireless LAN controller, and be sure the access point
and the Cisco wireless LAN controller are either on the same subnet or that the access point
has a route back to its primary, secondary, and tertiary Cisco wireless LAN controller. Also,
if the access point is not on the same subnet as the Cisco wireless LAN controller, be sure that
there is a properly configured DHCP server on the same subnet as the access point. See the
“Configuring DHCP Option 43 and DHCP Option 60” section on page 27 for additional
information.
Step 3
Reconfigure the Cisco wireless LAN controller so that it is not the Master.
13
ap3502getstartForJMR3.fm Page 14 Thursday, October 27, 2011 11:28 AM
Note
A Master Cisco wireless LAN controller should be used only for configuring access
points and not in a working network.
8 Troubleshooting
If you experience difficulty getting your access point installed and running, look for a solution to your
problem in this guide or in additional access point documentation. These, and other documents, are
available on Cisco.com.
Guidelines for Using Cisco Aironet Lightweight Access Points
Keep these guidelines in mind when you use 3502P lightweight access points:
• The access point can only communicate with Cisco wireless LAN controllers, such as 2100, 4400,
and 5500 series controllers.
• The access point does not support Wireless Domain Services (WDS) and cannot communicate with
WDS devices. However, the controller provides functionality equivalent to WDS when the access
point joins it.
• CAPWAP does not support Layer 2. The access point must get an IP address and discover the
controller using Layer 3, DHCP, DNS, or IP subnet broadcast.
• The access point console port is enabled for monitoring and debug purposes. All configuration
commands are disabled when the access point is connected to a controller.
Using DHCP Option 43
You can use DHCP Option 43 to provide a list of controller IP addresses to the access points, enabling
them to find and join a controller. For additional information, refer to the “Configuring DHCP Option
43 and DHCP Option 60” section on page 27.

Troubleshooting the Access Point Join Process
Access points can fail to join a controller for many reasons: a RADIUS authorization is pending;
self-signed certificates are not enabled on the controller; the access point’s and controller’s regulatory
domains don’t match, and so on.
Controller software enables you to configure the access points to send all CAPWAP-related errors to
a syslog server. You do not need to enable any debug commands on the controller because all of the
CAPWAP error messages can be viewed from the syslog server itself.
The state of the access point is not maintained on the controller until it receives a CAPWAP join
request from the access point. Therefore, it can be difficult to determine why the CAPWAP discovery
request from a certain access point was rejected. In order to troubleshoot such joining problems
without enabling CAPWAP debug commands on the controller, the controller collects information for
all access points that send a discovery message to it and maintains information for any access points
that have successfully joined it.
The controller collects all join-related information for each access point that sends a CAPWAP
discovery request to the controller. Collection begins with the first discovery message received from
the access point and ends with the last configuration payload sent from the controller to the access
point.
You can view join-related information for the following numbers of access points:
• Up to 300 access points for 4400 series controllers, the Cisco WiSM, and the Catalyst 3750G
Integrated Wireless LAN Controller Switch
• Up to three times the maximum number of access points supported by the platform for the 2100
series controllers and the Controller Network Module within the Cisco 28/37/38xx Series
Integrated Services Routers
When the controller is maintaining join-related information for the maximum number of access points,
it does not collect information for any more access points.
An access point sends all syslog messages to IP address 255.255.255.255 by default when any of the
following conditions are met:
• An access point running software release 5.2 or later has been newly deployed.
• An existing access point running software release 5.2 or later has been reset after clearing the
configuration.
If any of these conditions are met and the access point has not yet joined a controller, you can also
configure a DHCP server to return a syslog server IP address to the access point using option 7 on the
server. The access point then starts sending all syslog messages to this IP address.
When the access point joins a controller for the first time, the controller sends the global syslog server
IP address (the default is 255.255.255.255) to the access point. After that, the access point sends all
syslog messages to this IP address until it is overridden by one of the following scenarios:
17
ap3502getstartForJMR3.fm Page 18 Thursday, October 27, 2011 11:28 AM
• The access point is still connected to the same controller, and the global syslog server IP address
configuration on the controller has been changed using the config ap syslog host global
syslog_server_IP_address command. In this case, the controller sends the new global syslog server
IP address to the access point.
• The access point is still connected to the same controller, and a specific syslog server IP address
has been configured for the access point on the controller using the config ap syslog host specific
Cisco_AP syslog_server_IP_address command. In this case, the controller sends the new specific
syslog server IP address to the access point.
• The access point is disconnected from the controller and joins another controller. In this case, the
new controller sends its global syslog server IP address to the access point.
• Whenever a new syslog server IP address overrides the existing syslog server IP address, the old
address is erased from persistent storage, and the new address is stored in its place. The access
point also starts sending all syslog messages to the new IP address provided the access point can
reach the syslog server IP address.
You can configure the syslog server for access points and view the access point join information only
from the controller CLI.

10 Configuring DHCP Option 43 and DHCP Option 60
This section contains a DHCP Option 43 configuration example on a Windows 2003 Enterprise DHCP
server for use with Cisco Aironet lightweight access points. For other DHCP server implementations,
consult product documentation for configuring DHCP Option 43. In Option 43, you should use the
IP address of the controller management interface.
Note
DHCP Option 43 is limited to one access point type per DHCP pool. You must configure a
separate DHCP pool for each access point type.
The 3502P access point uses the type-length-value (TLV) format for DHCP Option 43. DHCP servers
must be programmed to return the option based on the access point’s DHCP Vendor Class Identifier
(VCI) string (DHCP Option 60). The VCI string for the 3502P access point is:
Cisco AP c3502
The format of the TLV block is listed below:
• Type: 0xf1 (decimal 241)
• Length: Number of controller IP addresses * 4
• Value: List of WLC management interfaces
To configure DHCP Option 43 in the embedded Cisco IOS DHCP server, follow these steps:
Step 1
Enter configuration mode at the Cisco IOS CLI.
Step 2
Create the DHCP pool, including the necessary parameters such as default router and name
server. A DHCP scope example is as follows:
ip dhcp pool 
27
ap3502getstartForJMR3.fm Page 28 Thursday, October 27, 2011 11:28 AM
network  
default-router 
dns-server 
Where:
 is the name of the DHCP pool, such as AP3502
 is the network IP address where the controller resides, such as
10.0.15.1
 is the subnet mask, such as 255.255.255.0
 is the IP address of the default router, such as 10.0.0.1
 is the IP address of the DNS server, such as 10.0.10.2
Step 3
Add the option 60 line using the following syntax:
option 60 ascii “VCI string”
For the VCI string, “Cisco AP c3502”. The quotation marks must be included.
Step 4
Add the option 43 line using the following syntax:
option 43 hex 
The hex string is assembled by concatenating the TLV values shown below:
Type + Length + Value
Type is always f1(hex). Length is the number of controller management IP addresses times 4
in hex. Value is the IP address of the controller listed sequentially in hex.
For example, suppose that there are two controllers with management interface IP addresses,
10.126.126.2 and 10.127.127.2. The type is f1(hex). The length is 2 * 4 = 8 = 08 (hex). The IP
addresses translate to 0a7e7e02 and 0a7f7f02. Assembling the string then yields
f1080a7e7e020a7f7f02. The resulting Cisco IOS command added to the DHCP scope is option 43 hex
f1080a7e7e020a7f7f02.
