1 About this Guide
This guide provides instructions on how to install your Cisco Catalyst 9117AX 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 9117AX series access point is referred to as access point or AP in this document.
2 About the Access Point
The Cisco Catalyst 9117AX Series wireless access point is a dual band, dual concurrent, enterprise 802.11ax AP. This
AP series offers integrated antenna options, designed to use both 2.4 GHz and the 5 GHz bands. This access point
supports a greater overall High Density Experience (HDX) which provides a more predictable performance for advanced
applications such as 4K or 8K video, high-density high-definition collaboration applications, all-wireless offices and
Internet-of-Things (IoT). The access point supports full interoperability with leading 802.11ax and 802.11ac clients, and
supports 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 Catalyst 9117AX Series Access
Point Data Sheet, at the following URL:
<URL to be added at CCO>

spectrum intelligence across 20-, 40-, and 80-, and 160-MHz-wide channels to combat performance problems
arising from wireless interference.
MIMO equalization capabilities, which optimize uplink performance and reliability by reducing the impact of signal
fade.
The AP supports both Cisco Mobility Express and lightweight deployments (using Cisco Wireless LAN controllers). The
AP also 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.
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 Wireshark (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.

7 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 15 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 3.

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.

Draft Label - Cisco Confidential
Cisco Catalyst 9117AX Series Access Points
d. Make sure DHCP is enabled on the network. The access point must receive its IP address through DHCP.
Note A Wave 2 Cisco AP will be assigned an IP address from the DHCP server only if a default router (gateway)
is configured on the DHCP server (enabling the AP to receive its gateway IP address) and the gateway
ARP is resolved.
This is not applicable to Wave 1 Cisco APs.
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.
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 14.
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.
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.)

8 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 the Access Point” section on page 13 for additional information.
Access point power options: PoE+ or Cisco Power Injector AIR-PWRINJ5= or AIR-PWRINJ6=.
Note If AIR-PWRINJ5= is used, the AP will work with reduced features.
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.

10 Powering the Access Point
The AP can be powered only through Power-over-Ethernet (PoE) using the following:
802.3at Cisco Power Injector AIR-PWRINJ6=
Note If USB is used with 802.3at power, the AP will work with reduced features.
802.3af Cisco Power Injector AIR-PWRINJ5=
Note If AIR-PWRINJ5= is used, the AP will work with reduced features.
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/8-2/configuration-guide/b_cg82.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 Catalyst 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 the release that supports 9117AX series access points, as specified in the access point data sheet.
14
Draft Label - Cisco Confidential
Cisco Catalyst 9117AX Series Access Points
Note You cannot edit or query any access point using the controller CLI if the name of the access point contains a
space.
Note Make sure that the controller is set to the current time. If the controller is set to a time that has already
occurred, the access point might not join the controller because its certificate may not be valid for that time.
Access points must be discovered by a controller before they can become an active part of the network. The access
point supports these controller discovery processes:
Layer 3 CAPWAP discovery—Can occur on different subnets than the access point and uses IP addresses and UDP
packets rather than MAC addresses used by Layer 2 discovery.
Locally stored controller IP address discovery—If the access point was previously joined to a controller, the IP
addresses of the primary, secondary, and tertiary controllers are stored in the access point 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-CAPWAP-CONTROLLER.localdomain, where localdomain is the access point domain name. Configuring the
CISCO-CAPWAP-CONTROLLER provides backwards compatibility in an existing customer deployment. When an
access point receives an IP address and DNS information from a DHCP server, it contacts the DNS to resolve
CISCO-CAPWAP-CONTROLLER.localdomain. When the DNS sends a list of controller IP addresses, the access
point sends discovery requests to the controllers.
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 17).
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 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
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.
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.
18
Draft Label - Cisco Confidential
Cisco Catalyst 9117AX Series Access Points
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.
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 9117AX series access point:
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.

Draft Label - Cisco Confidential
Cisco Catalyst 9117AX Series Access Points
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
Catalyst 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 9117AX 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 9117AX series access point is:
Cisco AP c9117AX
The format of the TLV block is listed below:
Type—0xf1 (decimal 241)
Length—Number of controller IP addresses * 4
Value—IP addresses of the WLC management interfaces listed sequentially in hex
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 AP9117AX
<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
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 802.11ax?
The IEEE 802.11ax standard, also known as the High-Efficiency-Wireless (HEW), builds off of the 802.11ac and delivers
a better experience in typical environments, and a more predictable performance for advanced applications such as 4K
or 8K video, high-density high-definition collaboration applications, all-wireless offices and Internet-of-Things (IoT).
802.11ax is designed to use both 2.4Ghz and the 5GHz bands, unlike prior standards.
How Does Auto-Link Aggregation work with the 9117AX?
The 9117AX 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 9117AX 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
What is a ClientLink 4.0? How is it different from Tx-Beamforming?
Cisco ClientLink 4.0 is a beamforming capability built into Cisco Catalyst 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 has software support for certain dongles.
