1 About this Guide
This guide provides instructions on how to install your Cisco Aironet 2800I and 2800E series access
points and provides links to resources which can help you configure the access point. This guide
provides mounting instructions and limited troubleshooting procedures.
The 2800 series access point is referred to as access point or AP in this document.
2 About the Access Point
The Cisco Aironet 2800 Series Wi-Fi access points provide 802.11ac Wave 2 with Multi User MIMO
(MU MIMO). This AP series offers integrated and external antenna options, with a dedicated 5 GHz
radio and a flexible radio that can be configured as a 2.4 GHz radio (default) or as an additional
5 GHz radio. This access point supports a greater overall High Density Experience (HDX) which
provides mission-critical wireless to meet your performance needs. The access points support full
interoperability with leading 802.11ac clients, and support a mixed deployment with other access
points and controllers.
A full listing of the access point's features and specifications are provided in the Cisco Aironet 2800
Series Access Point Data Sheet, at the following URL:

Access Point Features
The 2800 series access point is a wireless controller-based product and supports:
• Integrated antennas on the 2802I access point model (AIR-AP2802I-x-K9)
• External antennas on the 2802E access point models (AIR-AP2802E-x-K9)
Note The ‘x’ in the model numbers represents the regulatory domain. For information on
supported regulatory domains, see the“AP Model Numbers and Regulatory Domains”
section on page 4.
• Flexible Radio Assignment, allowing for either manual configuration or for the APs to intelligently
determine the operating role of the integrated radios based on the available RF environment. The
AP can operate in the following modes:
–
2.4 GHz and 5 GHz role, where one radio serves clients in 2.4 GHz mode, while the other
serves clients in 5 GHz mode.
3
–
Dual 5 GHz radio role, with both radios operating in the 5 GHz band, actively serving client
devices to maximize the benefits of 802.11ac Wave 2 and to increase client device capacity.
–
Wireless Security Monitoring and 5 GHz role, where one radio serves 5 GHz clients, while the
other radio scans both 2.4 GHz and 5 GHz for wIPS attackers, CleanAir interferers, and
rogue devices.
• Multiuser Multiple-Input Multiple-Output (MU-MIMO) technology with 3 spatial streams.
• Cross-AP Noise Reduction, a Cisco innovation that enables APs to intelligently collaborate in real
time about RF conditions so that users connect with optimized signal quality and performance.
• Optimized AP Roaming for ensuring that client devices associate with the AP in their coverage
range that offers the fastest data rate available.
• Cisco ClientLink 4.0 technology for improved downlink performance to all mobile devices,
including one-, two-, and three-spatial-stream devices up to 802.11ac Wave 1 and Wave 2. The
technology also improves battery life on mobile devices.

6 Preparing the AP for Installation
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 and Grounding the Access Point” section
on page 19 for additional information.
• Access point power options: PoE+ or Cisco Power Injector AIR-PWRINJ6=.
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.
7 Installation Overview
Installing the access point involves these operations:
Step 1 Performing a Pre-Installation Configuration, page 15 (optional)
Step 2 Mounting and Grounding the Access Point, page 19
Step 3 Powering the Access Point, page 21
Step 4 Preparing the AP for Installation, page 14
14
8 Performing a Pre-Installation Configuration
The following procedures ensure that your access point installation and initial operation go as
expected. 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 23 for details.
The following Pre-Installation Configuration procedure given does not include configuring Link
Aggregation. For information on configuring Link Aggregation, see the Cisco Wireless LAN
Controller Configuration Guide, Release 8.2, at this URL:
http://www.cisco.com/c/en/us/td/docs/wireless/controller/8-2/config-guide/b_cg82.html
The pre-installation configuration setup is illustrated in Figure 6.

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 for the release you are using, 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
16
documentation. See also the “Configuring DHCP Option 43” section on page 28 for more
information.
Note The 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.
Step 2 Apply power to the access point. See Powering the Access Point, page 21.
a. 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.
b. If the access point shuts down, check the power source.
c. 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 amber.
d. 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.
17
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.)
18
9 Mounting and Grounding the Access Point
Cisco Aironet 2800 series access points can be mounted in several configurations – on a suspended
ceiling, on a hard ceiling or wall, on an electrical or network box, and above a suspended ceiling.

10 Powering the Access Point
The AP can be powered through only Power-over-Ethernet (PoE), using:
• 802.3at Cisco Power Injector AIR-PWRINJ6=
• Any 802.3at (25.5 W) compliant switch port
11 Configuring and Deploying 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.
The information in this section does not include configuring Link Aggregation. For information on
configuring Link Aggregation, see the Cisco Wireless LAN Controller Configuration Guide, Release
8.2, at the following URL:
http://www.cisco.com/c/en/us/td/docs/wireless/controller/8-1/configuration-guide/b_cg81.html
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, inter-operable 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.
21
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 the release that supports 2800 series access points, as specified in
the access point data sheet.
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 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 15.
• 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”
section on page 28.
• 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
22
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.
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 (for LED descriptions, see “Checking the Access Point LEDs”
section on page 24).
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 chirping green if no clients are associated or
green 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” section on page 28 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.
23
12 Checking the Access Point LEDs
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 2.

13 Miscellaneous Usage and Configuration Guidelines
Using the Mode Button
Using the Mode button (see Figure 3) you can:
• Reset the AP to the default factory-shipped configuration.
• Clear the AP internal storage, including all configuration files.
To use the mode button, press, and keep pressed, the mode button on the access point during the
AP boot cycle. Wait until the AP status LED changes to Amber. During this, the AP console shows a
seconds counter, counting the number of seconds the mode button is pressed. Then:
• To reset the AP to the default factory-shipped configuration, keep the mode button pressed for less
than 20 seconds. The AP configuration files are cleared.
This resets all configuration settings to factory defaults, including passwords, WEP keys, the IP
address, and the SSID.
• To clear the AP internal storage, including all configuration files and the regulatory domain
configuration, keep the mode button pressed for more than 20 seconds, but less than 60 seconds.
The AP status LED changes from Amber to Red, and all the files in the AP storage directory are
cleared.
If you keep the mode button pressed for more than 60 seconds, the mode button is assumed faulty and
no changes are made.
25
Troubleshooting the Access Point to Cisco Controller Join Process
Note Ensure that your controller is running the latest Cisco Wireless Controller Software Release
as specified in the access point data sheet.
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 and the controller 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 28/37/28xx 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:
• An access point running software release 8.2.110.0 or later has been newly deployed.
26
• An existing access point running software release 8.2.110.0 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:
• 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.
Important Information for Controller-based Deployments
Keep these guidelines in mind when you use 2802 series access points:
• The access point can only communicate with Cisco wireless LAN 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.
27
Configuring 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.
The following is 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 2800 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 DHCP Vendor Class
Identifier (VCI) string (DHCP Option 43). The VCI string for the 2800 series access point is:
Cisco AP c2800
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 <pool name>
network <IP Network> <Netmask>
default-router <Default router>
dns-server <DNS Server>
Where:
<pool name> is the name of the DHCP pool, such as AP2802
<IP Network> is the network IP address where the controller resides, such as
10.0.15.1
28
<Netmask> is the subnet mask, such as 255.255.255.0
<Default router> is the IP address of the default router, such as 10.0.0.1
<DNS Server> is the IP address of the DNS server, such as 10.0.10.2
Step 3 Add the option 43 line using the following syntax:
option 43 hex <hex string>
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. Valu e 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.

14 FAQs
What is Flexible Radio Assignment?
The Flexible Radio Assignment (FRA) feature automatically detects when a high number of devices
are connected to a network and changes the dual radios in the access point from 2.4 GHz/5 GHz to
5 GHz/5 GHz to serve more clients. The access point performs this function while still monitoring the
network for security threats and RF Interference that may affect performance. Flexible Radio
Assignment improves mobile user experience for high-density networks.
FRA has the following different modes of operation:
•Default operating mode—Serving clients on both 2.4 GHz and 5 GHz radios.
•Dual 5 GHz Mode—Serving clients on both 5 GHz radios.
•Wireless Security Monitoring—Scanning both 2.4 GHz and 5 GHz radios for security threats while
also serving 5 GHz clients.
What is a Smart Antenna connector?
The 2802E model has a Smart antenna connector (see Figure 8), which is connected directly to the
flexible radio. Without a supported external antenna connected to the Smart Antenna connector, the
flexible radio can stay only in 2.4 GHz mode. If an external antenna is connected, the flexible radio
can be used in the full Flexible Radio Assignment mode, allowing dual 5 GHz and Wireless Security
Monitoring modes.
To connect to any supported RP-TNC connector-type external antenna to the Smart antenna
connector, use the DART cable connector AIR-CAB002-DART-R= (see Figure 9), which is to be
procured separately from Cisco.

How Does Auto-Link Aggregation work with the 2800?
The 2800 AP supports automatic Link Aggregation (LAG) across its Ethernet and AUX ports. This
provides up to 2 Gbps of uplink speed to the access point.
The following Cisco switching series support LAG with the 2800 AP:
• Catalyst 3850 / all models (non-CA mode)
• Catalyst 3650 / all models (non-CA mode)
• Catalyst 4500/Sup-8E
• Catalyst 6500/Sup 720 or newer
31
What is a ClientLink 4.0? How is it different from Tx-Beamforming?
Cisco ClientLink 4.0 is a beamforming capability built into Cisco Aironet wireless LAN access points.
When the access point concentrates signals toward the receiving client, that client is better able to hear
the AP’s transmission, and so throughput is greater. ClientLink also enhances performance in the
uplink (client-to-AP) direction, so that the AP can also better hear the client communications. The
result is improved performance in both directions, and doesn’t require any special capabilities in the
client device to work.
ClientLink works with all client technologies. It makes sure each client type always operates at the best
possible rate, as determined by the 802.11 access technology supported, network conditions, and the
distance of the client from the Wi-Fi AP. ClientLink helps maintain maximum client rates.
Can the USB port be used?
The USB port does not have any software support at this time.
