1 About this Guide
This guide provides instructions on how to install your Cisco Aironet 4800 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 4800 series access point is referred to as access point or AP in this document.
2 About the Access Point
The Cisco Aironet 4800 Series wireless access points provide 802.11ac Wave 2 with Multi User MIMO (MU MIMO). This AP series offers
integrated 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. In addition to this flexible (client serving) radio, there is a second flexible radio specifically for hyperlocation,
analytics, and monitoring. This AP supports a greater overall High Density Experience (HDX) which provides mission-critical wireless to
meet your performance needs. The AP supports full interoperability with leading 802.11ac clients, and supports a mixed deployment with
other APs and controllers.
A full listing of the access point's features and specification are provided in the Cisco Aironet 4800 Series Access Point Data Sheet, at the
following URL:
<CCO URL to be added at FCS>
Access Point Features
The 4800 series access point is a wireless controller-based product and supports:
Integrated antennas including built-in Hyperlocation antenna array containing 16 antenna elements designed for angle-of-arrival
(AoA) technology, capable of <3 m location accuracy on Wi-Fi.
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 6.
Three radios, where two are standard and the third is a listen-only, 0x4 radio. The third radio in listen-only mode allows the AP to
perform analytics, Hyperlocation, and Wireless Security Monitoring (WIPS and WIDS) while the two primary radios continue to serve
clients.
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.
— Dual 5 GHz radio 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 an d 5 GHz role, where on e 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.
Multigigabit Ethernet (mGig) support providing multiple Gigabit uplink speeds of 2.5 Gbps and 5 Gbps in addition to 100 Mbps and
1 Gbps speeds. All speeds are supported on Category 5e cabling, as well as 10GBASE-T cabling.
Multiuser Multiple-Input Multiple-Output (MU-MIMO) technology with 3 spatial streams.
MIMO equalization capabilities, which optimize uplink performance and reliability by reducing the impact of signal fade.
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.

Cisco Aironet 4800 Series Access Points
Optimized AP Roaming for ensuring that client devices associate with the AP in their coverage range that offers the fastest data rate
available.
Cisco CleanAir technology enhanced with 160MHz channel support. CleanAir delivers proactive, high-speed spectrum intelligence
across 20-, 40-, and 80-, and 160-MHz-wide channels to combat performance problems arising from wireless interference.
Analytics capabilities providing event-driven real-time data captures with real-time visibility into Cisco DNA Center and potential
third party analytics
Advanced location features
Built-in BLE radio capable of BLE TX/RX
Built-in compass to assist CMX/Cisco Prime Infrastructure
Cisco Prime Infrastructure support to address full location planning and serviceability tool as well as additional Hyperlocation mapping
enhancements
The AP supports the following operating modes:
Local—This is the default mode for the Cisco AP. In this mode, the AP does not serve clients.
Flexconnect—Flexconnect mode for the Cisco AP.
Monitor—This is the monitor-only mode for the Cisco AP.
SE-connect—Spectrum expert-only connect mode allows the AP to perform spectrum intelligence.
Sensor—Sensor mode for the Cisco AP.
Note The AP can only be configured to Sensor mode if it is an external antenna AP with no DART connected.
However, for external antenna APs with DAR T connected or internal antenna APs, only the dual-band radio can
be set to Sensor role. The dual-band radio can operate as a sensor on both the 2.4 GHz a nd 5 GH z bands. This
allows the other radio to serve clients or perform other operations on 5 GHz.
Sniffer—In the wireless sniffer mode, the AP starts sniffing the air on a given channel. It captures and forwards all the packets from
the clients on that channel to a remote machine that runs Airopeek or W ir eshark (packet analyzers for IEEE 802.11 wireless LANs).
This includes information on the time stamp, signal strength, packet size, etc.
Note In the sniffer mode, the server to which the data is sent should be on the same VLAN as the wireless controller
management VLAN otherwise an error will be displayed.
Security—Security mode for the Cisco AP.
Hyperlocation—Hyperlocation mode for the Cisco AP.

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 or on a flat horizontal surface.
Note Y ou 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 13 for addition al information.
9
Page 10
Cisco Aironet 4800 Series Access Points
Access point power options: PoE+ via powered switch, mid-span, or power injector (usually located in a wiring closet). If PoE+ is not
available, this access point may be powered by a local DC power supply (Cisco AIR-PWR-C).
Note When the access point is located above the ceiling tiles (in the building’s environmental airspace, also known as plenum)
care must be taken to ensure the power supply , or power injector if used, is not co-located in the building’s plenum airspace.
This may not be in compliance with local 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.
7 Installation Overview
Installing the access point involves these operations:
Step 1 Performing a Pre-Installation Configuration, page 10 (optional)
Step 2 Mounting and Grounding the Access Point, page 13
Step 3 Powering the Access Point, page 15
Step 4 Preparing the AP for Installation, page 9
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 connec t it to the network from there. See the
“Deploying the Access Point on the Wireless Network” section on page 17 for details.
The following pre-installation configuration procedure does not include configuring Link Aggregation or configuration via Cisco Mobility
Express.
Note • For information on configuring Link Aggregation, see the Cisco Wireless LAN Controller Configuration Guide,
Release 8.6, at this URL:
https://www.cisco.com/c/en/us/td/docs/wireless/controller/8-6/config-guide/b_cg86/ports_and_interfaces.html#ID1466

Link Aggregation Link Aggregation
The pre-installation configuration setup is illustrated in Figure3.
Figure 3 Pre-Installation Configuration Setup
To per form 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
Configuration 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 documentation. See also the “Configuring DHCP Option 43” section on page 20 for more
information.
Step 2 Apply power to the access point. See Powering the Access Point, page 15.
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.
11
Page 12
Cisco Aironet 4800 Series Access Points
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 controlle r 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 in dicating n ormal op eration. Discon nect
the access point and mount it at the location at which you intend to deploy it on the wi reless 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 NA T to an outside address. (Port Address Translation is
not supported.)

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 at the following URL:
https://www.cisco.com/c/en/us/support/wireless/wireless-lan-controller-software/products-installation-and-configuration-guides-list.html
The Controller Discovery Process
Note CAPWAP support is provided in con troller software release 5.2 or later. However, your controller must be running
the release that supports 4800 series access points, as specified in the access point data sheet.
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 (L WAPP) used with previous Cisco Aironet access points. LWAPP-enabl ed ac cess points are compatible with
CAPWAP, and conversion to a CAPWAP controller is seamless. Deployments can combine CAPWAP and LW APP software on the
controllers.
Note You cannot ed it or query any access point usin g the controller CLI if the name of the acce ss point contain s a space.
The functionality provided by the controller does not change except for customers who have Layer 2 deployments, which CAPWAP does
not support.
15
Page 16
Cisco Aironet 4800 Series Access Points
In a CAPWAP environment, a wireless access point discovers a controller by using CAPWAP discovery mechanisms and then sends it a
CAPW AP join request. The controller sends th e access point a CAPW AP join response allowing the access point to join the contro ller . When
the access point joins the controller, the controller manages its configuration, firmware, control transactions, and data transactions.
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.
For additional information about the discovery process and CAPWAP, see the Cisco Wire less LAN Controller Software Configuration
Guide. This document is available on Cisco.com.
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 10.
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 20.
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-CAPW AP-CONTR OLLER.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-CAPW AP-CONTROLLER.localdomain. When the DNS sends a list of co ntroller IP addresses, the access
point sends discovery requests to the controllers.

Cisco Aironet 4800 Series Access Points
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 18).
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 W ireless 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 20 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.

12 Checking the Access Point LEDs
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 2) 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 it’s 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.

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 regulatory domains of the access point and the controller 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 CAPW AP discovery request to the controller . Collection
begins with the first discovery message received from th e access point and ends with the last configuration payload sent fro m 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.
19
Page 20
Cisco Aironet 4800 Series Access Points
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.
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 4800 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.
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.
20
Page 21
Cisco Aironet 4800 Series Access Points
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 4800 series access point uses the type-length-value (TL V) format for DHCP Option 43. DHCP servers must be pr ogrammed to return
the option based on the access point DHCP Vendor Class Identifier (VCI) string (DHCP Option 43). The VCI string for the 4800 series
access point is:
Cisco AP c4800
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 paramet ers such as default router and nam e 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 AP4802
<IP Network> is the network IP address where the controller resides, such as 10.0.15.1
<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. 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.

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. FRA allows for either manual configuration
or for the APs to intelligently determine the operating role of the int egrated radios based on the available RF environment. Th e 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.
The AP can operate in the following modes:
• Default operating mode—Serving Clients on both 2.4 GHz and 5 GHz
the other serves clients in 5 GHz mode.
• Dual 5 GHz Mode—Serving clients on both 5 GH z Radios to maximize the benefits of 802.11ac Wave 2 and to increase client
device capacity.
• Wireless Security Monitoring and 5 GHz role—Flexible radio that serves 5 GHz clients, while the other radio scans both 2.4 GHz
and 5 GHz for wIPS attackers, CleanAir interferers, and rogue devices.
, where one radio serves clients in 2.4 GHz mode, while
What is Cisco Multigigabit Ethernet?
Cisco Multigigabit Ethernet (mGig) is a unique Cisco innovation debuting in the Cisco Aironet 4800 Access Points. With the increasing
popularity of 802.11ac and new wireless applications, wireless devices now require more network bandwidth. Hence, there is a need for a
technology that supports speeds higher than 1 Gbps on all cabling infrastructure. Cisco Multigigabit technology allows you to achieve
bandwidth speeds from 1 to 10 Gbps over traditional Cat 5e cabling or newer. The Cisco AP4800 supports up to 5 Gbps using mGig.
For more information see the Cisco Multigigabit FAQ at the following URL:
http://www.cisco.com/c/dam/en/us/solutions/collateral/enterprise-networks/catalyst-multigigabit-switching/multigigabit-ethernet-technolo
gy.pdf
How Does Auto-Link Aggregation work with the 4800?
The 4800 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. When operating in LAG, the Multigigabit Ethernet port will operate as a single Gigabit Ethernet port.
The following Cisco switching series support LAG with the 4800 AP:
Catalyst 3850/all models (non-CA mode)
