Introduction to the Access Point

The Cisco Aironet 1550 Series Outdoor Mesh Access Point (hereafter called the access point or AP) is a ruggedized outdoor access point designed for service in mesh networks. The 1550 series leverages 802.11n technology with integrated radio and internal/external antennas. The 1550 outdoor platform consists of Multiple Input Multiple Output (MIMO) WLAN radios and integrated spectrum intelligence (Clean Air).

CleanAir provides full 802.11n data rates while detecting, locating, classifying and mitigating radio frequency (RF) interference to provide the best client experience possible. CleanAir technology on the outdoor 11n platform mitigates WiFi and non-WiFi interference on both 2.4 GHz and 5 GHz radios.

The 1550 AP series 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 1550 series supports the modularity of the 1520 series and allows flexibility in radio configuration. In addition to full interoperability with 802.11n clients, the 1550 series interoperates with legacy clients and offers enhanced backhaul performance. The 1552C access point is configured with an integrated DOCSIS 3.0 cable modem.

The access point is a standalone unit that can be cable strand 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-multipoint mesh deployments. The controllers use a browser-based management system, a command-line interface (CLI), or the Cisco Prime Infrastructure network management system to manage the controller and the associated access points. The access point is compliant with Wi-Fi Protected Access 2 (WPA2) and employs hardware-based Advanced Encryption Standard (AES) encryption between wireless nodes to provide end-to-end security.

Note The FCC limits the amount of power this device can transmit. Power transmitted is a combination of the amplification of the signal and the antenna gain. The access point has been designed to operate with the Cisco provided antennas.

Integrated Antenna Option

The 1552C and 1552I models use the 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 antennas 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 antenna have a peak gain of about 2 dBi at 2.4 GHz and 4 dBi at 5 GHz. The antenna unit is gray weatherproof radome for outdoor operation.

The low profile integrated antennas are attached to the bottom of a Cisco access point. The 1552C comes with the option of a C-bracket for strand mounting. The 1552C mesh access point chassis mounting brackets and low profile antenna all fit within the 30 cm vertical right-of-way for cable strand-mounted equipment. The antennas are internally connected to the diplexer ports of the outdoor mesh access point 2.4/5 GHz 2x3 MIMO radios.

Figure 12 shows an installed integrated low-profile dual-band (2.4 GHz and 5.25 GHz) 3-element array antenna. It is available on models AIR-CAP1552I-x-K9 and AIR-CAP1552C-x-K9.

The access point POC cable modem configuration contains an internal cable modem for connection to the cable network from the pole-mounted cable lines. The access point can be powered using the 40-to 90-VAC (quasi-square wave AC) power provided by the cable network.

The cable modem supports these main features:

  • Data Over Cable Service Interface Specifications (DOCSIS)3.0
  • Backward compatibility with existing DOCSIS 1.1 and 1.0 networks

Fiber Option


Warning Class 1 laser product. Statement 1008

The factory-orderable fiber option provides a fiber input and output capability. Fiber data is transmitted and received over a single-strand fiber cable, which is connected to the access point using these small-factor pluggable (SFP) modules:

  • 100BASE-BX10-U fiber Rugged SFP module
  • 1000BASELX single-mode Rugged SFP module
  • 1000BASESX multimode Rugged SFP module

Note SFP modules are not hot-swappable.

One fiber connection is available on both the 1552E and 1552H access points. The fiber connection is on the bottom of both the 1552E and 1552H access points (shown on Figure 1). Client data is passed to the network controller through the fiber connection via a fiber capable switch. For detailed installation information about the fiber option, see the Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation Guide. Configuration information can be found in the controller configuration guide of the controller you are using.

Network Deployment Examples

The access point is a wireless device designed for wireless client access and point-to-point bridging, point-to-multipoint bridging, and point-to-multipoint mesh wireless connectivity. The access point provides 5-GHz backhaul capability to link with another access point to reach a wired network connection or to provide repeater operations for other access points.

The access point plays two primary radio roles: a root access point (hereafter called a RAP) or a mesh (non-root) access point (hereafter called a MAP), which is the default role of all access points. When the access point has a fiber or wired Ethernet or cable connector connection to the controller (through a switch), the radio role is called a RAP. In order to be considered a RAP, the access point must be configured as a RAP. A RAP is a parent node to any bridging or mesh network. A controller can support one or more RAPs, each one parenting the same or different wireless networks. There can be more than one RAP for the same mesh network for redundancy. RAPs and MAPs can support wireless clients on the 2.4-GHz and 5-GHz band. Client access on 5-GHz is called universal client access.

When the access point does not have a wired Ethernet connection to the controller (through a switch), the radio role is called a MAP. The MAPs have a wireless connection (through the backhaul interface) to other MAPs and finally to a RAP which has an Ethernet connection through a switch to the controller. MAPs may also have a wired Ethernet connection to a local LAN and serve as a bridge endpoint for that LAN (using a point-to-point or point-to-multipoint bridge connection).

Wireless Backhaul

The access point supports wireless backhaul capability using the 5-GHz radio to bridge to another access point to reach a wired network connection to a controller as shown in Figure 13 . The access point connected to the wired network is considered a RAP in this configuration. The remote access point is considered a MAP and transfers wireless client traffic to the RAP for transfer to the wired network. Control And Provisioning of Wireless Access Points (CAPWAP) control traffic is also transferred over this bridged link.

Figure 13 Access Point Backhaul Example

 

 

Point-to-Point Bridging

The access points can be used to extend a remote network by using the 5-GHz backhaul radio to bridge the two network segments as shown in Figure 14 . To support Ethernet bridging, you must enable bridging on the controller for each access point. By default this capability is turned-off for all access points.

Wireless client access is supported; however, if bridging between tall buildings, the 2.4-GHz wireless coverage area may be limited and possibly not suitable for direct wireless client access.

Figure 14 Access Point Point-to-Point Bridging Example

 

 

Point-to-Multipoint Bridging

The access points can be used as a RAP to connect multiple remote MAPs with their associated wired networks. By default this capability is turned-off for all access points. To support Ethernet bridging, you must enable bridging on the controller for each access point. Wireless client access can be provided over the bridging link; however, if bridging between tall buildings, the 2.4-GHz wireless coverage area may be limited and possibly not suitable for direct wireless client access.

Figure 15 illustrates an example of access point-to-multipoint bridging.

Figure 15 Access Point Point-to-Multipoint Bridging Example

 

Point-to-Multipoint Mesh Network

The access point is typically deployed in a mesh network configuration. In a typical mesh deployment, one or more RAPs have a wired network connection through a switch to a controller. Other remote MAPs without wired network connections use the backhaul feature to optimally link to a RAP that is connected to the wired network. In the mesh network, the links between the access points are referred to as the backhaul links.

Intelligent wireless routing is provided by the Adaptive Wireless Path protocol (AWPP). This enables each MAP to identify its neighbors and intelligently choose the optimal path to the RAP with the wired network connection by calculating the cost of each path in terms of signal strength and the number of hops required to get to a controller with signal strength given priority since signal strength determines the data rate available for backhaul.

Figure 16 illustrates a typical mesh configuration using access points.

Figure 16 Typical Mesh Configuration Using Access Points

 

Layer 3 Network Operation

The access points support Layer 3 network operation. Access points and controllers in Layer 3 configurations use IP addresses and UDP packets, which can be routed through large networks.
Layer 3 operation is scalable and is the recommended operation. Figure 17 illustrates a typical Layer-3 wireless network configuration containing access points and a controller.

Figure 17 Typical Layer 3 Access Point Network Configuration Example

 

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 7.0. 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.

Site Surveys

Cisco recommends that you perform a site survey before installing the equipment. A site survey reveals problems that can be resolved before the network is operational. Because 802.11a/b/g/n operates in an unlicensed spectrum, there may be sources of interference from other 802.11a wireless devices (especially in multi-tenant buildings) that could degrade your 802.11 signals. A site survey can determine if such interference exists at the time of deployment.

A proper site survey involves temporarily setting up mesh links and taking measurements to determine whether your antenna calculations are accurate. Determine the correct locations and antenna types before you drill holes and route cables and mounting equipment.


Tip When power is not readily available during a site survey, use an unrestricted power supply (UPS) to temporarily power the mesh link.

Consider the following operating and environmental conditions when performing a site survey:

  • How far is your wireless link?
  • Has a previous site survey been conducted?
  • Do you have a clear Fresnel zone between the access points or radio line of sight?
  • What is the minimum acceptable data rate within the link?
  • Do you have the correct antenna (if more than one antenna is being offered)?
  • Do you have access to both of the mesh site locations?
  • Do you have the proper permits, if required?
  • Are you following the proper safety procedures and practices?
  • Have you configured the access points before you go onsite? It is always easier to resolve configurations or device problems first.
  • Do you have the proper tools and equipment to complete your survey?

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 the 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.
  • Become familiar with the access point connections ( Figure 1 , Figure 3 , and Figure 8 ).
  • Verify that the switch you are using to connect the controller is configured properly.

Note For additional installation, mounting and safety information for the outdoor mesh access point, see the Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation Guide, which is available on Cisco.com, and Safety Warnings for Cisco Aironet 1520 Series Outdoor Mesh Access Points, which accompanies this guide.

Deploying the Access Point


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

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:

  • Make sure that the wireless LAN controller is set to Layer 3 mode
  • Verify the wireless LAN controller software version
  • Record the access point BVI MAC address
  • Enter the access point BVI MAC address to the wireless LAN controller filter list

Verifying the Wireless LAN Controller Mode

Follow these steps to verify that the wireless LAN controller mode is set to Layer 3:


Step 1 Open your web-browser and enter the IP address of your wireless LAN controller. Be sure to precede the IP address with https://. A login screen appears.

Step 2 Enter your username and password. The default case-sensitive username and password are admin and admin. The Summary page appears.

Verifying the Wireless LAN Controller Software Version

On the Summary page, you can verify the software version that the wireless LAN controller is running. If a version update is necessary, refer to the appropriate controller configuration documentation.

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 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.

Step 7 Enter a description (32 characters maximum) of the access point in the Description field.

Step 8 Choose an interface from the Interface Name pop-up menu.

Step 9 Click Apply .

Step 10 Repeat this process to add other access points to the list.


Note You can also use the controller CLI command config macfilter add to add a MAC filter entry on the controller.

Step 11 On the menu bar, click Monitor to return to the Monitor Summary page.


 

Verifying Controller Association

To verify that your access point is associated to the wireless LAN controller, perform these steps:


Step 1 Log into your controller web interface (https) using a web browser.

Step 2 Click Wireless and verify that your access point MAC address is listed under Ethernet MAC.

Step 3 Log out of the controller and close your web browser.


 

Deployment Notes

Using a DHCP Server in a Layer 3 Mesh Network

To use a DHCP server in a Layer 3 mesh network, make sure the wireless LAN controller is in Layer 3 mode. You must also 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 Aironet 1000 and 1500 (1505 and 1510) series access points use a comma-separated string format for DHCP Option 43. Other Cisco Aironet 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 strings for Cisco access points capable of operating in lightweight mode are listed in Table 1 :

1.For controller release 4.1 or later.

2.For controller release 4.0, the VCI depends on the model.

The format of the TLV block for 1100, 1130, 1200, 1240, 1250, 1300, 1520, and 1552 access points are listed below:

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

Configuring Option 43 for Cisco 1000, 1500, and 1550 Series Access Points

To configure DHCP Option 43 for Cisco 1000, 1500, and 1550 series access points 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 AP1000.
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 Table 1 . The quotation marks must be included.

Step 4 Add the option 43 line using the following syntax:

option 43 ascii “Comma Separated IP Address List”
 

For example, if you are configuring Option 43 for Cisco 1000, 1500, or 1550 series access points using the controller IP addresses 10.126.126.2 and 10.127.127.2, add the following line to the DHCP pool in the Cisco IOS CLI:

option 43 ascii “10.126.126.2,10.127.127.2”

The quotation marks must be included.


 

Configuring Option 43 for Cisco 1100, 1130, 1200, 1240, 1250, 1300, 1520, and 1550 Series Access Points

To configure DHCP Option 43 for Cisco 1100, 1130, 1200, 1240, 1250, 1300, 1520, and 1550 series access points 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 AP1550.
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 Table 1 . 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

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 points can only communicate with controllers and cannot operate independently in standalone mode.
  • The access point communicates only with controllers and does not support Wireless Domain Services (WDS). The access points cannot communicate with WDS devices. However, the controller provides functionality equivalent to WDS when an access point associates to it.
  • 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.

Checking the LEDs

Four LEDs, located between the PoE-In and PoE-Out connectors, monitor the status of the access point power, uplinks, and radios. Figure 19 identifies and describes the LED functions. Table 2 provides additional LED signal information.

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.

See the Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation Guide for a detailed description of the LEDs and additional troubleshooting tips.

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 addressing 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 an mesh 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.
