Chapter 1: Introduction The Outdoor 5 GHz Wireless Bridge system consists of two models that provide point-to-point or point-to-multipoint IEEE 802.11a wireless links between remote Ethernet LANs: • WB2011– Provides only external antenna options and is designed to operate as the “Master” bridge in point-to-multipoint configurations, supporting wireless connections to as many as 16 WB2011 Slave units.
1 Introduction Inform your dealer if there are any incorrect, missing or damaged parts. If possible, retain the carton, including the original packing materials. Use them again to repack the product in case there is a need to return it.
Hardware Description 1 External Antenna Options (WB2011 Only) The WB2011 Master bridge unit does not include an integrated antenna, but provides various external antenna options. In a point-to-multipoint configuration an external high-gain omnidirectional, or panel antenna can be used to communicate with up to 16 bridges spread over a wide area. The external antenna connects to the N-type RF connector on the WB2011 using the provided coaxial cable.
1 Introduction However, when connecting the access point to a workstation or other device that does not have MDI-X ports, you must use crossover twisted-pair cable. LED Indicator Input Data from Local Network Switch AC Power Socket (Hidden) Output Data and Power to Wireless Bridge The wireless bridge does not have a power switch. It is powered on when its Ethernet port is connected to the power injector module, and the power injector module is connected to an AC power source.
System Configuration 1 System Configuration System Components At each location where a unit is installed, it must be connected to the local network using the power injector module. The following figure illustrates the system component connections.

Chapter 2: Bridge Link Planning The Outdoor 5 GHz Wireless Bridge supports fixed point-to-point or point-to-multipoint wireless links. A single link between two points can be used to connect a remote site to larger core network. Multiple bridge links can provide a way to connect widespread Ethernet LANs. For each link in a wireless bridge network to be reliable and provide optimum performance, some careful site planning is required.
2 Bridge Link Planning Radio Path Planning Although the wireless bridge uses IEEE 802.11a radio technology, which is capable of reducing the effect of multipath signals due to obstructions, the wireless bridge link requires a “radio line-of-sight” between the two antennas for optimum performance. The concept of radio line-of-sight involves the area along a radio link path through which the bulk of the radio signal power travels. This area is known as the first Fresnel Zone of the radio link.
Radio Path Planning 2 When planning the radio path for a wireless bridge link, consider these factors: • Avoid any partial line-of-sight between the antennas. • Be cautious of trees or other foliage that may be near the path, or may grow and obstruct the path. • Be sure there is enough clearance from buildings and that no building construction may eventually block the path.
2 Bridge Link Planning Total Link Distance Max Clearance for 60% of First Fresnel Zone at 5.8 GHz Approximate Clearance for Earth Curvature Total Clearance Required at Mid-point of Link 15 miles (24.1 km) 35 ft (10.7 m) 45 ft (13.7 m) 80 ft (24.4 m) 17 miles (27.4 km) 37 ft (11.3 m) 58 ft (17.7 m) 95 ft (29 m) Note that to avoid any obstruction along the path, the height of the object must be added to the minimum clearance required for a clear radio line-of-sight.
Radio Path Planning 2 • Avoid placing the wireless bridge too close to any metallic, reflective surfaces, such as roof-installed air-conditioning equipment, tinted windows, wire fences, or water pipes • The wireless bridge antennas at both ends of the link must be positioned with the same polarization direction, either horizontal or vertical Antenna Polarization — The wireless bridge’s antenna sends a radio signal that is polarized in a particular direction.
2 Bridge Link Planning maximum wind velocity and direction at the site and be sure that any supporting structure, such as a pole, mast, or tower, is built to withstand this force. • Lightning — The wireless bridge includes its own built-in lightning protection. However, you should make sure that the unit, any supporting structure, and cables are all properly grounded. Additional protection using lightning rods, lightning arrestors, or surge suppressors may also be employed.
Chapter 3: Hardware Installation Before mounting antennas to set up your wireless bridge links, be sure you have selected appropriate locations for each antenna. Follow the guidance and information in Chapter 2, “Wireless Link Planning.” Also, before mounting units in their intended locations, you should first perform initial configuration and test the basic operation of the wireless bridge links in a controlled environment over a very short range.
3 2. Hardware Installation Place the U-shaped part of the bracket around the pole and tighten the securing nut just enough to hold the bracket to the pole. (The bracket may need to be rotated around the pole during the alignment process.) Attach bracket to pole with mounting grooves facing up 3. Use the included nuts to tightly secure the wireless bridge to the bracket. Be sure to take account of the antenna polarization direction; both antennas in a link must be mounted with the same polarization.
Mount the Unit 3 Mounting on Larger Diameter Poles In addition, there is a method for attaching the pole-mounting bracket to a pole that is 2 to 5 inches in diameter using an adjustable steel band clamp (not included in the kit). A steel band clamp up to 0.5 inch (1.27 cm) wide can be threaded through the main part of the bracket to secure it to a larger diameter pole without using the U-shaped part of the bracket. This method is illustrated in the following figure.
3 Hardware Installation 2. Position the bracket in the intended location and mark the position of the three mounting screw holes. 3. Drill three holes in the wall that match the screws and wall plugs included in the bracket kit, then secure the bracket to the wall. 4. Use the included nuts to tightly secure the wireless bridge to the bracket.
Connect Cables to the Unit 3 Connect Cables to the Unit 1. Attach the Ethernet cable to the Ethernet port on the wireless bridge. Note: The Ethernet cable included with the package is 30 m (100 ft) long. To wire a longer cable (maximum 100 m, 325 ft), follow the connector pinout information in Appendix B. 2. For extra protection against rain or moisture, apply weatherproofing tape (not included) around the Ethernet connector. 3.
3 Hardware Installation AC power Ethernet cable from LAN switch Inp ut Ou tpu t Power LED indicator Ethernet cable to wireless bridge 3. Insert the power cable plug directly into the standard AC receptacle on the power injector. 4. Plug the other end of the power cable into a grounded, 3-pin socket, AC power source. Note: For International use, you may need to change the AC line cord. You must use a line cord set that has been approved for the receptacle type in your country. 5.
Align Antennas 3 The RSSI connector provides an output voltage between 0 and 3.28 VDC that is proportional to the received radio signal strength. The higher the voltage reading, the stronger the signal. The radio signal from the remote antenna can be seen to have a strong central main lobe and smaller side lobes. The object of the alignment process is to set the antenna so that it is receiving the strongest signal from the central main lobe.
3 Hardware Installation 2. Pan the antenna horizontally back and forth by rotating the mounting bracket around the pole while checking the RSSI voltage. 3. Find the point where the signal is strongest (highest voltage) and secure the mounting bracket firmly to the pole. Note: Sometimes there may not be a central lobe peak in the voltage because vertical alignment is too far off; only two similar peaks for the side lobes are detected. In this case, fix the antenna halfway between the two peaks. 4.
Chapter 4: Initial Configuration The wireless bridge offers a variety of management options, including a web-based interface, a command line interface (CLI), or using SNMP management software. Most initial configuration steps can be made through the web browser interface using the Setup Wizard (page 4-3). However, for units that do not have a preset country code, you must first set the country code using the CLI. Note: Units sold in some countries are not configured with a specific country code.
4 Initial Configuration Initial Configuration Steps Setting the Country Code – Regulations for wireless products differ from country to country. Setting the country code restricts the wireless bridge to use only the radio channels and power settings permitted in the specified country of operation. If the wireless bridge unit is shipped with a preset country code, you are not permitted to change it, as required by country regulations.
Using the Web-based Management Setup Wizard 4 Using the Web-based Management Setup Wizard There are only a few basic steps you need to complete to set up the wireless bridge for your network. The Setup Wizard takes you through configuration procedures for the radio channel selection, IP configuration, and basic WEP encryption for wireless security. The wireless bridge can be managed by any computer using a web browser (Internet Explorer 5.0 or above, or Netscape Navigator 6.2 or above).
4 Initial Configuration Launching the Setup Wizard – To perform initial configuration, click Setup Wizard on the home page, then click on the [Next] button to start the process.
Using the Web-based Management Setup Wizard 1. 4 Radio Channel – You must enable radio communications for the 802.11a radio and set the operating channel. • 802.11a Turbo Mode – If you select Enable, the wireless bridge will operate in turbo mode with a data rate of up to 108 Mbps. Normal mode supports 13 channels, Turbo mode supports only 5 channels. (Default: Disable) 802.11a Radio Channel – Set the operating radio channel number. (Default: 56ch, 5.
4 2. Initial Configuration IP Configuration – Either enable or disable (Dynamic Host Configuration Protocol (DHCP) for automatic IP configuration. If you disable DHCP, then manually enter the IP address and subnet mask. If a management station exists on another network segment, then you must enter the IP address for a gateway that can route traffic between these segments.
Using the Web-based Management Setup Wizard 3. Security – Enable Wired Equivalent Privacy (WEP) encryption and set an encryption key. 4. Click Finish. 5. Click the OK button to restart the access point.
4 4-8 Initial Configuration
Chapter 5: System Configuration Before continuing with advanced configuration, first complete the initial configuration steps described in Chapter 4 to set up an IP address for the wireless bridge. The wireless bridge can be managed by any computer using a web browser (Internet Explorer 5.0 or above, or Netscape Navigator 6.2 or above). Enter the default IP address: http://192.168.1.1 To log into the wireless bridge, enter the default user name “admin” and click LOGIN (there is no default password).
5 System Configuration Menu Description Page Filter Control Enables VLAN support and filters traffic matching specific Ethernet protocol types 5-6 SNMP Controls access to this wireless bridge from management stations using SNMP, as well as the hosts that will receive trap messages 5-7 Administration Configures user name and password for management access; upgrades software from local file, FTP or TFTP server; resets configuration settings to factory defaults; and resets the wireless bridge 5-10
5 Advanced Configuration System Name – An alias for the wireless bridge, enabling the device to be uniquely identified on the network. (Default: Outdoor Bridge; Range: 1-22 characters) Location – A text string that describes the system location. (Maximum length: 20 characters) Contact – A text string that describes the system contact. (Maximum length: 255 characters) CLI Commands for System Identification – Enter the global configuration mode and use the system name command to specify a new system name.
5 System Configuration By default, the wireless bridge will be automatically configured with IP settings from a Dynamic Host Configuration Protocol (DHCP) server. However, if you are not using a DHCP server to configure IP addressing, use the CLI to manually configure the initial IP values (page 4-2). After you have network access to the wireless bridge, you can use the web browser interface to modify the initial IP configuration, if needed.
5 Advanced Configuration If you have management stations, DNS, or other network servers located on another subnet, type the IP address of the default gateway router in the text field provided. Otherwise, leave the address as all zeros (0.0.0.0). • Primary and Secondary DNS Address: The IP address of Domain Name Servers on the network. A DNS maps numerical IP addresses to domain names and can be used to identify network hosts by familiar names instead of the IP addresses.
5 System Configuration Filter Control The wireless bridge can employ VLAN tagging support and network traffic frame filtering to control access to network resources and increase security. Native VLAN ID – The VLAN ID used to tag traffic passing from the wireless interface to the wired network. (Range: 1-64) VLAN – Enables or disables VLAN tagging support on the wireless bridge (changing the VLAN status forces a system reboot).
5 Advanced Configuration CLI Commands for VLAN Support – From the global configuration mode use the native-vlanid command to set the default VLAN ID for the Ethernet interface, then enable VLANs using the vlan enable command. When you change the access point’s VLAN support setting, you must reboot the access point to implement the change. To view the current VLAN settings, use the show system command.
5 System Configuration SNMP – Enables or disables SNMP management access and also enables the wireless bridge to send SNMP traps (notifications). SNMP management is enabled by default. Community Name (Read Only) – Defines the SNMP community access string that has read-only access. Authorized management stations are only able to retrieve MIB objects.
5 Advanced Configuration CLI Commands for SNMP – Use the snmp-server enable server command from the global configuration mode to enable SNMP. To set read/write and read-only community names, use the snmp-server community command. The snmp-server host command defines a trap receiver host. To view the current SNMP settings, use the show snmp command.
5 System Configuration Administration Changing the Password Management access to the web and CLI interface on the wireless bridge is controlled through a single user name and password. You can also gain additional access security by using control filters (see “Filter Control” on page 5-6). To protect access to the management interface, you need to configure an Administrator’s user name and password as soon as possible.
Advanced Configuration 5 Upgrading Firmware You can upgrade new wireless bridge software from a local file on the management workstation, or from an FTP or TFTP server. After upgrading new software, you must reboot the wireless bridge to implement the new code. Until a reboot occurs, the wireless bridge will continue to run the software it was using before the upgrade started. Also note that rebooting the wireless bridge with new software will reset the configuration to the factory default settings.
5 System Configuration Firmware Upgrade Local – Downloads an operation code image file from the web management station to the wireless bridge using HTTP. Use the Browse button to locate the image file locally on the management station and click Start Upgrade to proceed. • New firmware file: Specifies the name of the code file on the server. The new firmware file name should not contain slashes (\ or /), the leading letter of the file name should not be a period (.
5 Advanced Configuration be used to check that the new file is present in the wireless bridge file system. To run the new software, use the reset board command to reboot the wireless bridge.

5 System Configuration Enabling System Logging The wireless bridge supports a logging process that can control error messages saved to memory or sent to a Syslog server. The logged messages serve as a valuable tool for isolating wireless bridge and network problems. System Log Setup – Enables the logging of error messages. Logging Host – Enables the sending of log messages to a Syslog server host. Server Name/IP – The IP address or name of a Syslog server.
5 Advanced Configuration command to set the facility-type number to use on the Syslog server. To view the current logging settings, use the show logging command. Outdoor Outdoor Outdoor Outdoor Outdoor Outdoor Outdoor Bridge(config)#logging Bridge(config)#logging Bridge(config)#logging Bridge(config)#logging Bridge(config)#logging Bridge(config)#exit Bridge#show logging on level alert console host 1 10.1.0.
5 System Configuration indicate the number of hours your time zone is located before (east) or after (west) UTC. Enable Daylight Saving – The wireless bridge provides a way to automatically adjust the system clock for Daylight Savings Time changes. To use this feature you must define the month and date to begin and to end the change from standard time. During this period the system clock is set back by one hour.
Advanced Configuration 5 Wireless Distribution System (WDS) The IEEE 802.11a standard defines a WIreless Distribution System (WDS) for connections between wireless bridges. The outdoor wireless bridge uses WDS to forward traffic on links between units. When using WDS, only wireless bridge units can associate to each other. A wireless client cannot associate with any unit in a wireless bridge network.
5 System Configuration MAC Address – The physical layer address of the wireless bridge unit at the other end of the wireless link. (12 hexadecimal digits in the form “xx:xx:xx:xx:xx:xx”) Port Status – Enables or disables the wireless bridge link. Note: The wireless MAC address for each bridge unit is printed on the label on the back of the unit.
Advanced Configuration 5 Bridge Aging Time – Changes the aging time for entries in the dynamic address table: • Ethernet: The time after which a learned Ethernet port entry is discarded. (Range: 60-1800 seconds; Default: 100 seconds) • Wireless 802.11a: The time after which a learned wireless entry is discarded.
5 System Configuration CLI Commands for Bridging – The following example shows how to set the MAC address aging time for the wireless bridge.
5 Advanced Configuration Spanning Tree Protocol (STP) The Spanning Tree Protocol (STP) can be used to detect and disable network loops, and to provide backup links between switches, bridges or routers. This allows the wireless bridge to interact with other bridging devices (that is, an STP-compliant switch, bridge or router) in your network to ensure that only one route exists between any two stations on the network, and provide backup links which automatically take over when a primary link goes down.
5 System Configuration Forward Delay – The maximum time (in seconds) this device waits before changing states (i.e., discarding to learning to forwarding). This delay is required because every device must receive information about topology changes before it starts to forward frames. In addition, each port needs time to listen for conflicting information that would make it return to a discarding state; otherwise, temporary data loops might result.
Advanced Configuration 5 Priority – Defines the priority used for this port in the Spanning Tree Protocol. If the path cost for all ports on a switch are the same, the port with the highest priority (i.e., lowest value) will be configured as an active link in the spanning tree. This makes a port with higher priority less likely to be blocked if the Spanning Tree Protocol is detecting network loops.
5 System Configuration CLI Commands for STP – The following example configures spanning tree paramters for the bridge and wireless port 5.
5 Radio Interface Radio Interface The IEEE 802.11a radio interface includes configuration options for radio signal characteristics and wireless security features. Note: The radio channel settings for the wireless bridge are limited by local regulations, which determine the number of channels that are available. Radio Settings (802.11a) The IEEE 802.11a interface operates within the 5 GHz band, at up to 54 Mbps in normal mode or up to 108 Mbps in Turbo mode.
5 System Configuration Note: In normal mode, the wireless bridge provides a channel bandwidth of 20 MHz, and supports the maximum number of channels permitted by local regulations (e.g., 11 channels for the United States). In Turbo Mode, the channel bandwidth is increased to 40 MHz to support the increased data rate. However, this reduces the number of channels supported (e.g., 5 channels for the United States).
5 Radio Interface the wireless bridge will save all broadcast/multicast frames for the Basic Service Set (BSS) and forward them after every second beacon. Using smaller DTIM intervals delivers broadcast/multicast frames in a more timely manner, causing stations in Power Save mode to wake up more often and drain power faster. Using higher DTIM values reduces the power used by stations in Power Save mode, but delays the transmission of broadcast/multicast frames.

5 Radio Interface Setting up IEEE 802.11 Wired Equivalent Privacy (WEP) shared keys enables the wireless bridge to prevent unauthorized access to the network. Be sure to define at least one static WEP key for data encryption. Also, be sure that the WEP keys are the same for all bridge units in the wireless network. Data Encryption Setup – Enable or disable the wireless bridge to use either WEP or AES for data encryption.
5 System Configuration Advanced Encryption Standard (AES) AES has been designated by the National Institute of Standards and Technology as the successor to the Data Encryption Standard (DES) encryption algorithm, and will be used by the U.S. government for encrypting all sensitive, nonclassified information. Because of its strength, and resistance to attack, AES is also being incorporated as part of the 802.11 security standard.
5 Radio Interface • Alphanumeric: Enter keys as an alphanumeric string using between 8 and 31 characters. Note: For each wireless port link (1 to 16), the AES keys must match on the corresponding bridge unit. CLI Commands for WEP Security – From the 802.11a interface configuration mode, use the encryption command to enable WEP encryption. To enter WEP keys, use the key command, and then set one key as the transmit key using the transmit-key command.
5 System Configuration CLI Commands for AES Security – From the 802.11a interface configuration mode, use the encryption command to enable AES encryption. To enter AES keys, use the key command. To view the current security settings, use the show interface wireless a command. Outdoor Bridge(config)#interface wireless a Enter Wireless configuration commands, one per line.

Chapter 6: Command Line Interface Using the Command Line Interface Accessing the CLI When accessing the management interface for the wireless bridge via a Telnet connection, the wireless bridge can be managed by entering command keywords and parameters at the prompt. Using the wireless bridge’s command-line interface (CLI) is very similar to entering commands on a UNIX system. Telnet Connection Telnet operates over the IP transport protocol.
6 Command Line Interface Entering Commands This section describes how to enter CLI commands. Keywords and Arguments A CLI command is a series of keywords and arguments. Keywords identify a command, and arguments specify configuration parameters. For example, in the command “show interface ethernet,” show and interface are keywords, and ethernet is an argument that specifies the interface type. You can enter commands as follows: • To enter a simple command, enter the command keyword.
