CHAP T ER

Autonomous Access Points
Cisco Aironet 1130AG Series Access Point (models: AIR-AP1131AG and AIR-AP1131G) supports a
management system based on Cisco IOS software. The 1130AG series access point is a Wi-Fi certified,
wireless LAN transceiver. The 1131AG access point uses dual integrated radios (IEEE 802.11g and
IEEE-802.11a). The 1131G access point uses a single integrated radio (IEEE 802.11g).
The access point serves as the connection point between wireless and wired networks or as the center
point of a stand-alone wireless network. In large installations, wireless users within radio range of an
access point can roam throughout a facility while maintaining uninterrupted access to the network.
You can configure and monitor the access point using the command-line interface (CLI), the
browser-based management system, or Simple Network Management Protocol (SNMP).
Lightweight Access Points
The Cisco Aironet 1130AG Series Access Point (models: AIR-LAP1131AG and AIR-LAP1131G) is
part of the Cisco Integrated Wireless Network Solution and requires no manual configuration before they
are mounted. The lightweight access point is automatically configured by a Cisco wireless LAN
controller (hereafter called a controller) using the Lightweight Access Point Protocol (LWAPP).
OL-8369-05
Cisco Aironet 1130AG Series Access Point Hardware Installation Guide

Guidelines for Using 1130AG Series Lightweight Access Points
The lightweight 1131AG access point contains two integrated radios: a 2.4-GHz radio (IEEE 802.11g)
and a 5-GHz radio (IEEE 801.11a). The lightweight 1131G access point contains one integrated radio:
a 2.4-GHz radio (IEEE 802.11g). Using a controller, you can configure the radio settings.
In the Cisco Centralized Wireless LAN architecture, access points operate in the lightweight mode (as
opposed to autonomous mode). The lightweight access points associate to a controller. The controller
manages the configuration, firmware, and controls transactions such as 802.1x authentication. In
addition, all wireless traffic is tunneled through the controller.
LWAPP is an Internet Engineering Task Force (IETF) draft protocol that defines the control messaging
for setup and path authentication and run-time operations. LWAPP also defines the tunneling mechanism
for data traffic.
In an LWAPP environment, a lightweight access point discovers a controller by using LWAPP discovery
mechanisms and then sends it an LWAPP join request. The controller sends the lightweight access point
an LWAPP join response allowing the access point to join the controller. When the access point is joined,
the access point downloads its software if the versions on the access point and controller do not match.
After an access point joins a controller, you can reassign it to any controller on your network.
LWAPP secures the control communication between the lightweight access point and controller by
means of a secure key distribution, using X.509 certificates on both the access point and controller.
This chapter provides information on the following topics:

• Hardware Features, page 1-3
• Network Examples with Autonomous Access Points, page 1-7
Guidelines for Using 1130AG Series Lightweight Access Points
You should keep these guidelines in mind when you use a 1130AG series lightweight access point:
• The access points can communicate only with 2006 or 4400 series controllers. Cisco 4100 series,
Airespace 4012 series, and Airespace 4024 series controllers are not supported because they lack
the memory required to support access points running Cisco IOS software.
• The access points do not support Wireless Domain Services (WDS). The access points communicate
only with controllers and cannot communicate with WDS devices. However, the controller provides
functionality equivalent to WDS when the access point associates to it.
• The access points support eight BSSIDs per radio and a total of eight wireless LANs per access
point. When a lightweight access point associates to a controller, only wireless LANs with IDs 1
through 8 are pushed to the access point.
• The access points do not support Layer 2 LWAPP. They must get an IP address and discover the
controller using DHCP, DNS, or IP subnet broadcast.
• The access point console port is enabled for monitoring and debuging purposes (all configuration
commands are disabled after connecting to a controller).

Hardware Features
Single or Dual-Radio Operation
The 1131AG access point supports simultaneous radio operation using a 2.4-GHz 802.11g radio and a
5-GHz 802.11a radio. The 1131G access point supports a single 2.4-GHz 802.11g radio. Each radio uses
dual-diversity integrated antennas.
The 5-GHz radio incorporates an Unlicensed National Information Infrastructure (UNII) radio
transceiver operating in the UNII 5-GHz frequency bands. The 802.11g radio is called Radio0 and the
802.11a radio is called Radio1.
Ethernet Port
The auto-sensing Ethernet port accepts an RJ-45 connector, linking the access point to your 10BASE-T
or 100BASE-T Ethernet LAN. The access point can receive power through the Ethernet cable from a
power injector, switch, or power patch panel. The Ethernet MAC address is printed on the label on the
back of the access point (refer to the
port is located in a cable bay area that is hidden by the closed top cover (see Figure 1-1).

Power Sources
Hardware Features
The access point can receive power from an external power module or from inline power using the
Ethernet cable. The access point supports the IEEE 802.3af inline power standard and Cisco CDP Power
Negotiation. Using inline power, you do not need to run a power cord to the access point because power
is supplied over the Ethernet cable.
Warning
Caution Be careful when handling the access point; the bottom plate might be hot.
This product must be connected to a Power over Ethernet (PoE) IEEE 802.3af compliant power source
or an IEC60950 compliant limited power source.
Statement 353
The access point supports the following power sources:
• Power module
• Inline power:
–
Cisco Aironet Power Injector (AIR-PWRINJ3 or AIR-PWRINJ-FIB)
–
An inline power capable switch, such as the Cisco Catalyst 3550 PWR XL, 3560-48PS,
3570-48PS, 4500 with 802.3AF PoE module, or the 6500 with 802.3AF PoE module
–
Other inline power switches supporting the IEEE 802.3af inline power standard
Note Some switches and patch panels might not provide enough power to operate the access point when
configured with both 2.4-GHz and 5-GHz radios. At power-up, if the access point is unable to determine
that the power source can supply sufficient power, the access point automatically deactivates both radios
to prevent an over-current condition. The access point also activates a Status LED low power error
indication (refer to the
“Low Power Condition for Autonomous Access Points” section on page 3-6 or
the “Low Power Condition for Lightweight Access Points” section on page 4-6).
UL 2043 Certification
The access point has adequate fire resistance and low smoke-producing characteristics suitable for
operation in a building's environmental air space, such as above suspended ceilings, in accordance with
Section 300-22(c) of the NEC, and with Sections 2-128, 12-010(3) and 12-100 of the Canadian
Electrical Code, Part 1, C22.1.
Caution Only the fiber-optic power injector (AIR-PWRINJ-FIB) has been tested to UL 2043 for operation in a
building’s environmental air space; the AIR-PWRINJ3 power injector and the power module are not

Network Examples with Autonomous Access Points
This section describes the autonomous access point’s role in three common wireless network
configurations. The autonomous access point’s default configuration is as a root unit connected to a
wired LAN or as the central unit in an all-wireless network. The repeater or workgroup bridge roles
require a specific configurationsetting.
The autonomous 1130AG series access point supports these operating wireless modes:
• Root access point—Connected to a wired LAN and supports wireless clients.
• Repeater access point—Not connected to a wired LAN, associates to a root access point, and
supports wireless clients
• Workgroup bridge—Not connected to a wired LAN, associates to a root access point or bridge, and
supports wired network devices.

Network Examples with Autonomous Access Points
Root Unit on a Wired LAN
An autonomous access point connected directly to a wired LAN provides a connection point for wireless
users. If more than one autonomous access point is connected to the LAN, users can roam from one area
of a facility to another without losing their connection to the network. As users move out of range of one
access point, they automatically connect to the network (associate) through another access point. The
roaming process is seamless and transparent to the user.

Repeater Unit that Extends Wireless Range
An autonomous access point can be configured as a stand-alone repeater to extend the range of your
infrastructure or to overcome an obstacle that blocks radio communication. The repeater forwards traffic
between wireless users and the wired LAN by sending packets to either another repeater or to an access
point connected to the wired LAN. The data is sent through the route that provides the best performance
for the client.

Central Unit in an All-Wireless Network
In an all-wireless network, an autonomous access point acts as a stand-alone root unit. The autonomous
access point is not attached to a wired LAN; it functions as a hub linking all stations together. The access
point serves as the focal point for communications, increasing the communication range of wireless
users.

Workgroup Bridge Configuration
When configured in the workgroup bridge mode, the autonomous unit provides a wireless connection
for remote wired devices to a Cisco Aironet access point or to a Cisco Aironet bridge.
In Figure 1-7, the unit is configured in workgroup bridge mode and is associated to a Cisco Aironet
access point as a wireless client device. This configuration allows the Ethernet-enabled devices to pass
Ethernet traffic to and from the main LAN using the workgroup bridge.

In Figure 1-8, the autonomous unit is configured in workgroup bridge mode and is associated to a Cisco
Aironet root bridge as a wireless bridge device. This configuration allows the Ethernet-enabled devices
pass Ethernet traffic to and from the main LAN using the workgroup bridge. The main advantage of this
configuration is that the wireless communication link can be over a longer distance than an access point
supports. Typically, an access point can communicate over approximately a 1-mile range; however, the
bridge-to-bridge wireless link can communicate over approximately a 21-mile range.

Basic Installation Guidelines
Basic Installation Guidelines
Because the access point is a radio device, it is susceptible to interference that can reduce throughput
and range. Follow these basic guidelines to ensure the best possible performance:
• Ensure a site survey has been performed to determine the optimum placement of access points.
• For lightweight access points, check the latest release notes to ensure that your controller software
version supports the access points to be installed. You can find the controller release notes by
selecting your controller under Wireless LAN Controllers at this URL:
http://www.cisco.com/en/US/products/hw/wireless/tsd_products_support_category_home.html
• Ensure that access points are not mounted closer than 20 cm (7.9 in) from
• Do not mount the access point within 3 feet of metal obstructions.
• Install the access point away from microwave ovens. Microwave ovens operate on the same
frequency as the access point and can cause signal interference.
• Do not mount the access point outside of buildings.
• Do not mount the access points on walls or other vertical surfaces.

Controller Discovery Process for Lightweight Access Points
The lightweight access point supports these controller discovery processes:
• DHCP server discovery—Uses DHCP Option 43 to provide controller IP addresses to the
lightweight access points. Cisco switches support a DHCP server option. For additional information,
refer to the
• DNS server discovery—The lightweight access point uses the name
CISCO-LWAPP-CONTROLLER.<local domain> to discover the controller IP addresses from a
DNS server. Where <local domain> is the access point domain name.
• Locally stored controller IP addresses—If the lightweight access point was previously associated to
a controller, the IP addresses of the primary, secondary, and tertiary controllers are stored in the
access point non-volitile memory. The process of storing controller IP addresses in access points for
later deployment is called priming the lightweight access point. For additional information, refer to
the
“Priming Lightweight Access Points Prior to Deployment” section on page F-1.
You can also manually configure controller information using CLI commands on new
(out-of-the-box) access points that are not connected to a controller. For additional information refer
to the
page 4-8.
Cisco recommends that you configure a DHCP server with Option 43 to provide the controller IP
addresses to your lightweight access points. Cisco switches provide a DHCP server option that is
typically used for this purpose.
