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 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 7.6.120.x or later to support 2700 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:
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:
Note You can mount the access point above a suspended ceiling but you must purchase additional mounting hardware: See “Mounting the Access Point” section for additional information.
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.
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 for details.
The pre-installation configuration setup is shown in Figure 4.
Figure 4 Pre-Installation Configuration Setup
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 Prime Infrastructure 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.
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 for more information.
Step 2 Apply power to the access point:
a. The access point should be powered by any 802.3at compliant device.
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:
– Access point power injector (AIR-PWRINJ4)
– Any 802.3af compliant power injector is supported, but in this case the access point will dynamically shift from 3x4 to 3x3.
Note The 2702 series access point requires a gigabit Ethernet (GbE) 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.
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 Prime Infrastructure to customize the access-point-specific 802.11ac 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 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.)
Cisco Aironet 2702 series access points can be mounted in several configurations, including on a suspended ceiling, on a hard ceiling or wall, on an electrical or network box, and above a suspended ceiling. Click this URL to browse to complete access point mounting instructions:
http://www.cisco.com/en/US/docs/wireless/access_point/mounting/guide/apmount.html
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 (for LED descriptions, see “Checking the Access Point LED” section).
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 for additional information.
Step 3 Reconfigure the Cisco wireless LAN controller so that it is not the Master.
Note A Master Cisco wireless LAN controller should be used only for configuring access points and not in a working network.
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.
Keep these guidelines in mind when you use 2702 series lightweight access points:
For Cisco Unified Wireless Networks Release 8.1.102.0 and older, the auxiliary Ethernet port labeled AUX is:
– You can connect the AP to end devices such as projectors, phones, Point of Sale Terminals and so on, through this port.
– Do not connect another AP or devices such as switches or hubs to this port as they can create spanning loop problems. Also, do not connect the AUX port to the same uplink switch as the AP.
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.
The location of the access point status LED is shown in Figure 2.
Note Regarding LED status colors, it is expected that there will be small variations in color intensity and hue from unit to unit. This is within the normal range of the LED manufacturer’s specifications and is not a defect.
The access point status LED indicates various conditions and are described in Table 1.
Note The controller must be running Cisco IOS Software Release 7.6.120.x or later to support 2700 series access points.
A detailed explanation of the join process is on Cisco.com at the following URL:
http://www.cisco.com/c/en/us/support/docs/wireless/4400-series-wireless-lan-controllers/99948-lap-notjoin-wlc-tshoot.html
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 up to three times the maximum number of access points supported by the platform for the 2500 series controllers and the Controller Network Module within the Cisco 28/37/38xx Series Integrated Services Routers.
Note The maximum number of access points varies for the Cisco WiSM2, depending on which controller software release is being used.
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:
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:
You can configure the syslog server for access points and view the access point join information only from the controller CLI.

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 2700 series 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 2700 series access point is:
Note If your access point was ordered with the Service Provider Option (AIR-OPT60-DHCP) selected in the ordering tool, the VCI string for the access point contains ServiceProvider. For example, a 2700 with this option will return this VCI string:
Cisco AP c2700-ServiceProvider
The format of the TLV block is listed below:
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:
Step 3 Add the option 60 line using the following syntax:
Step 4 Add the option 43 line using the following syntax:
The hex string is assembled by concatenating the TLV values shown below:
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.
