Introduction to the Access Point

The Cisco Aironet 1530 Series Outdoor Access Point (hereafter called the access point or AP) is a rugged outdoor access point designed for service in outdoor and mesh networks. The 1530 series leverages 802.11n technology with integrated radio and internal/external antennas.

The 1530 contains a 2.4-GHz and 5-GHz radio with an option to configure in centralized, Flexconnect, or mesh mode. The 2.4-GHz radios are used primarily for local access, and the 5-GHz radios can be configured for both local access and/or wireless backhaul in the Mesh mode.

The access point is a standalone unit that can be wall, pole or tower mounted. The access point can also operate as a relay node for other access points not directly connected to a wired network. Intelligent wireless routing is provided by the Adaptive Wireless Path Protocol (AWPP). This enables each access point to identify its neighbors and intelligently choose the optimal path to the wired network by calculating the cost of each path in terms of signal strength and the number of hops required to get to a controller. The access point is configured, monitored, and operated through a Cisco wireless LAN controller (WLC), referred to as a controller in this document. The WLC is described in the appropriate Cisco Wireless LAN Controller Configuration Guide. The Cisco Mesh Networking Solution Deployment Guide describes how to plan and initially configure the Cisco mesh network, which supports wireless point-to-point and point-to-multipoint mesh deployments. The controllers use a browser-based management system, a command-line interface (CLI), or the Cisco Prime Infrastructure (CIP) network management system to manage the controller and the associated access points.

Radio Operation and Antennas

AP 1532I

The AP 1532I uses an Integrated Low Profile Dual-Band 2.4/5 GHz Dipole Antenna Array. The antenna contains an array of three dual-band dipole antennas. The three dipole antennas are contained within this single radome, thereby greatly reducing the antenna’s visual footprint, and greatly reducing the possibility of snagging the antenna on the cable bundle, the RF cable, or test cables. The antennas operate over both 2.4 GHz and 5.25 – 5.85 GHz bands. Each of the three dipole antennas is a dual-band antenna, covering both the 2.4 – 2.483 GHz band, and the 5.25 – 5.85 GHz bands. The antennas have a peak gain of about 3 dBi at 2.4 GHz and 5 dBi at 5 GHz. The antenna unit is gray weatherproof radome for outdoor operation.

The 1532I access point 802.11b/g/n radio is used primarily for local access and its 802.11a/n radio for wireless backhaul in the Mesh.

The 2-GHz b/g/n radio operates in 2.4 GHz ISM band. It supports channels 1-11 in US, 1-13 in Europe, and 1-13 in Japan. It has three transmitters with a maximum total output power of 29dBm for 802.11b/g/n operation. Output power is configurable for 8 levels in 3 dB steps. It has three receivers that enables maximum-ratio combining (MRC).

The 5 GHz a/n radio operates in the UNII-2 band (5.25 - 5.35 GHz), UNII-2 Extended/ETSI band (5.47- 5.725 GHz), and the upper ISM band (5.725 - 5.850 GHz). It has two transmitters with a maximum total output power of 27 dBm depending on the regulatory domain. The total maximum output power for the upper ISM band is 27 dBm for A-domain. Tx power settings will change depending on the regulatory domain. Output power is configurable in 3 dB steps. Its three receivers enable maximum-ratio combining (MRC).

The 1532I access point is equipped with three integrated dual-band antennas with 3 dBi gain at 2 GHz and 5 dBi at 5 GHz.


Warning Do not locate the antenna near overhead power lines or other electric light or power circuits, or where it can come into contact with such circuits. When installing the antenna, take extreme care not to come into contact with such circuits, because they may cause serious injury or death. For proper installation and grounding of the antenna, please refer to national and local codes (for example, U.S.:NFPA 70, National Electrical Code, Article 810, Canada: Canadian Electrical Code, Section 54). Statement 1052


Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
Statement 1030

AP 1532E

The 1532E is equipped with two N-type radio frequency (RF) connectors (antenna ports 1 and 2) on the bottom of the unit for external antennas to support multiple input multiple output (MIMO) operation in dual-band mode, as shown in Figure 6 . The 1532E must always be operated with the two external antennas attached. When using the Cisco Aironet AIR-ANT2547V-N Dual-Band Omnidirectional Antenna, the 2.4- and 5-GHz antennas connect directly to the access point, as shown in Figure 7 . If the antennas are remotely located, an appropriate low-loss RF coax cable should be used.

The 1532E access point are equipped with 4 N-type radio frequency (RF) connectors (antenna ports 1 and 2 on the bottom of the unit for 2-GHz and antenna ports 3 and 4 on the top of the unit for 5-GHz) for external antennas to support multiple input multiple output (MIMO) operation. The antenna ports located of top of the 1532E are shown in Figure 3 . The 1532E must always be operated with the appropriate external antennas attached. Ports 1 and 2 can be used for Dual Band operation with a software configuration.


Note The antenna port caps must be removed for a uni-band antenna installation, but ports 3 and 4 should remain capped for a dual-band antenna instlalation to provide an IP67 seal.

Grounding the Access Point

The access point must be grounded before connecting power.


Warning This equipment must be externally grounded using a customer-supplied ground wire before power is applied. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 366


Warning Installation of the equipment must comply with local and national electrical codes. Statement 1074

In all outdoor installations and when powering the access point with AC power, you must follow these instructions to properly ground the access point:


Step 1 If using insulated 6-AWG copper ground wire, strip the insulation as required for the grounding lug.

Step 2 Use the appropriate crimping tool to crimp the bare 6-AWG copper ground wire to the supplied grounding lug.


Note The grounding lug and hardware used must comply with local and national electrical codes.

Step 3 Open the electrical joint compound (supplied), and apply a liberal amount over the metal surface where the ground strap screw holes are located (see Figure 5).

Step 4 Connect the grounding lug to the access point grounding screw holes (see Figure 5) using the supplied two Phillips head screws (M4 x 10 mm) with lock washers. Tighten the grounding screw to 22 to 24 in. lbs (2.49 to 2.71 Nm).

Step 5 If necessary, strip the other end of the ground wire and connect it to a reliable earth ground, such as a grounding rod or an appropriate grounding point on a metal streetlight pole that is grounded.

Preparing the Access Point

The access point is a radio device which is susceptible to common causes of interference that can reduce throughput and range. Follow these basic guidelines to ensure the best possible performance:

  • For information on planning and initially configuring your Cisco mesh network, refer to the Cisco Wireless Mesh Access Points, Design and Deployment Guide, Release 7.6. These documents are available on Cisco.com.
  • Do not install the access point in an area where structures, trees, or hills obstruct radio signals to and from the access point.
  • You can install the access point at any height, but best throughput is achieved when the access points are mounted at the same height.

Note To perform path loss calculation and to determine how far apart to install access points, consult an RF planning expert.


Note For information on conducting a site survey prior to installing the access point, see the Cisco Aironet 1530 Series Outdoor Access Point Hardware Installation Guide.

Avoiding Damage to Radios in a Testing Environment

The radios on outdoor units (bridges) have higher transmit power levels than radios on indoor units (access points). When you test radios in a link, you must avoid exceeding the maximum receive input level of the receiver. At levels higher than the normal operating range and packet error rate (PER) performance of the receiver is degraded. At even higher levels, the receiver can be permanently damaged.

To avoid receiver damage and PER degradation, you can use one of the following techniques:

  • Separate the omnidirectional antennas by at least 2 ft (0.6 m) to avoid receiver damage or by at least 25 ft (7.6 m) to avoid PER degradation.
  • Reduce the configured transmit power to the minimum level.
  • Cable the radios together using a combination of attenuators, combiners, or splitters to achieve a total attenuation of at least 60 dB.

For a radiated test bed, the following equation describes the relationships among transmit power, antenna gain, attenuation, and receiver sensitivity:

txpwr + tx antenna gain + rx ant gain - [attenuation due to antenna spacing] < max rx input level
 
Where:
 
txpwr = Radio transmit power level
tx gain = transmitter antenna gain
rx gain = receiver antenna gain
 

For a conducted test bed, the following equation describes the relationships among transmit power, antenna gain, and receiver sensitivity:

txpwr - [attenuation due to coaxial RF Attenuator components] < max rx input level (0 dbm)
 

Caution Under no circumstances should you connect the antenna port from one access point to the antenna port of another access point without using an RF attenuator. If you connect antenna ports you must not exceed the maximum survivable receive level of 0 dBm. Never exceed 0 dBm or damage to the access point can occur. Using attenuators, combiners, and splitters having a total of at least 60 dB of attenuation ensures that the receiver is not damaged and PER performance is not degraded.

Before You Begin


Warning Read the installation instructions before connecting the system to the power source. Statement 1004

Before you begin the installation process:

  • Become familiar with the procedures for mounting the access point (see the AP Pole/Wall Mount).
  • Become familiar with the access point connections ( Figure 1 , Figure 4 , and Figure 5 ).
  • Verify that the switch you are using to connect the controller is configured properly.

Deploying the Access Point

The following portions of this manual address how to deploy the Access Point. There are several deployment methods.


Warning Do not operate the unit near unshielded blasting caps or in an explosive environment unless the device has been modified to be especially qualified for such use. Statement 364

Controller-based Deployments

The access point is deployed on Layer 3 networks. Layer 3 is the default mode for a newly configured wireless LAN controller. This guide assumes that you will be deploying your access point on a Layer 3 network and a DHCP server is available.

Before deploying the access point, make sure the controller to which the access point will associate is properly configured by performing the following operations:

  • Verify the wireless LAN controller software version
  • Record the access point BVI MAC address (MAC address is located on the label on the side of the unit.)
  • Enter the access point BVI MAC address to the wireless LAN controller filter list

Recording the Access Point MAC Address

Use a text file to record the MAC address of all the access points you intend to deploy in your network. Having a file of the access point MAC addresses will be of considerable value for future testing. While you are compiling the list, you might want to change the name of the access point to something you can easily remember. The name can contain up to 32 characters. The following example, fisher_street:ea:co contains the last four HEX characters of the access point MAC address.

Adding the Access Point MAC Address to the Wireless LAN Controller
Filter List

The wireless LAN controller maintains an access point authorization MAC address list and responds to discovery requests from access points on that list. To add the access point MAC address (or MAC addresses) to the Wireless LAN controller filter list, follow these steps:


Step 1 If you are not logged onto the wireless LAN controller, log on now. The Summary page appears.

Step 2 On the menu bar, click SECURITY . The Security RADIUS Authentication Server page appears.

Step 3 Under AAA in the left frame, click MAC Filtering. The Security MAC Filtering page appears.

Deployment Notes

Using a DHCP Server in a Layer 3 Mesh Network

To use a DHCP server in a Layer 3 mesh network, you must configure DHCP option 43 on the DHCP server. After the controller is restarted, the access point receives IP addresses from the DHCP server.

Configuring DHCP Option 43

You can use DHCP Option 43 to provide a list of controller IP addresses to the access points, enabling each access point to find and join a controller. This section contains a DHCP Option 43 configuration example on a Microsoft Windows 2003 Enterprise DHCP server for use with Cisco Aironet lightweight access points.

Additional information about Microsoft DHCP Option 43 is available on Cisco.com at the following URL:

http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a00808714fe.shtml

DHCP Option 43 server implementation information for Cisco IOS is available at cisco.com at the following URL:

http://www.cisco.com/en/US/docs/wireless/technology/controller/deployment/guide/dep.html#wp1068287


Note In DHCP 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.

Cisco 1532 access points use the type-length-value (TLV) format for DHCP Option 43. DHCP servers must be programmed to return the option based on the DHCP Vendor Class Identifier (VCI) string (DHCP Option 60) of the access point. The VCI string for the Cisco 1532 access point is Cisco AP c1530.

The format of the TLV block for the 1532 access point is listed below:

  • Type: 0xf1 (decimal 241)
  • Length: Number of controller IP addresses * 4
  • Value: List of WLC management interfaces

Configuring Option 43 for Cisco 1532 Access Points

To configure DHCP Option 43 for Cisco 1532 access point 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. The commands used to create a DHCP pool are 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 AP1532.
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 60 line using the following syntax:

option 60 ascii “VCI string”
 

For the VCI string, use the value from Configuring DHCP Option 43 . The quotation marks must be included.

Step 4 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 listed below:

option 43 hex f1080a7e7e020a7f7f02
 


 

Autonomous Mode Configuration

The 1530 Series allows the Unified (controller-based) and Autonomous mode software to be loaded at the factory on the same hardware part number. This eliminates the need for separate part numbers for controller-based units and autonomous mode units.

At boot-up, the default mode is controller-based. The 1530 will power up and begin searching for a controller. Once it joins the controller, it will download the active Unified image from the controller. This is the same operation as other Cisco controller-based APs.

For Autonomous mode, the user should take the following steps:


Step 1 Power the AP and connect to the console.

Step 2 From the Command Line, enter:

AP # capwap ap autonomous (# means privileged EXEC mode)

Step 3 The system will respond with "Convert to Autonomous image. Proceed? (yes/[No]):"

Step 4 Type "yes" to confirm.

Step 5 The AP will then re-boot and load the Autonomous image. The unified image is erased.

Step 6 Once the 1530 has booted in autonomous mode, configuration of the AP can done by following the procedure outlined here:

Troubleshooting


Caution No serviceable parts inside. Do not open.

This section provides troubleshooting procedures for basic problems with the access point. For the most up-to-date, detailed troubleshooting information, refer to the Cisco Support website at cisco.com.

Guidelines for Using the Access Point

You should keep these guidelines in mind when you use the access point:

  • The access point supports Layer 3 CAPWAP communications with the controllers. In Layer 3 operation, the access point and the controller can be on the same or different subnets. The access point communicates with the controller using standard IP packets. Layer 3 operation is scalable and is recommended by Cisco. Unless it has a static IP address, a Layer 3 access point on a different subnet than the controller requires a DHCP server on the access point subnet and a route to the controller. The route to the controller must have destination UDP ports 12222 and 12223 open for CAPWAP communications. The routes to the primary, secondary, and tertiary controllers must allow IP packet fragments.
  • Before deploying your mesh access points ensure that the following has been done:

Your controllers are connected to switch ports that are configured as trunk ports.

Your mesh access points are connected to switch ports that are configured as untagged access ports.

A DHCP server is reachable by your mesh access points and has been configured with Option 43. Option 43 is used to provide the IP addresses of the Management Interfaces of your controllers. Typically, a DHCP server can be configured on a Cisco Layer 3 switch or router.

Optionally a DNS server can be configured to enable a local domain Cisco CAPWAP controller (CISCO-CAPWAP-CONTROLLER.<local domain>) to resolve to the IP address of the Management Interface of your controller.

Your controllers are configured and reachable by the mesh access points.

Your controllers are configured with the MAC addresses of the mesh access points.

Misconfigured Access Point IP address

IP address misconfiguration can occur when you are re-addressing a segment of your mesh network and you start at the mesh access point connected to the wired network (RAP). To avoid this problem, always start the IP address changes from the farthest access point and work your way back to the root access point. This problem might also happen if you move equipment such as uninstalling amesh access point and then redeploying with a different IP subnet in another physical location on the mesh network.

Another option to fix this misconfigured IP address is to physically take a controller in Layer 3 mode with a root access point to the location of the misconfigured mesh access point. Set the bridge group name for the root access point to match the misconfigured access point. Add the access point MAC address to the filter list of the controller. When the misconfigured access point appears in the Summary page of the controller, configure the access point with an IP address.

If you are using a static IP address on the access point and plan on redeploying the access point on another subnet, perform a clear config command from the controller for that access point while it is joined before you remove it from the network.

Verifying the Controller MAC Filter List

Prior to activating your access point, you must ensure that the access point MAC address has been added to the controller MAC Filter list and that Mac Filter List is enabled. To view the MAC addresses added to the controller MAC filter list and ensure the MAC filter list is enabled, you can use the controller CLI or the controller GUI.

Controller CLI

Use the show macfilter summary controller CLI command to view the MAC addresses added to the controller filter list.

Controller GUI

Log into your controller web interface (HTTPS) using a web browser and click SECURITY > AAA > MAC Filtering to view the MAC addresses added to the controller filter list. Then click Wireless > Mesh to ensure the MAC filter list is enabled.
