1.3 About The 9150

The 9150 Wireless Gateway is designed to support a wide variety of system config­urations. Using the IEEE 802.11b Wireless LAN Standard, the 9150 is capable of operating as a transparent bridge (access point) between wireless and wired networks. This allows wireless clients to access the network and also move seamlessly between the 9150s in the network. The 9150 can also operate as a Teklogix base station, remote radio module (RRM) or a mini-controller, and become part of a mapRF system.
additional information that is critical to the operation of the computer and other equipment.
injury, damage to the equipment, or loss of data.
Because the 9150 provides Ethernet connectivity, it can be added to an existing LAN. The 9150T provides the high-performance of 100Mb/s Fast Ethernet LANs, as well as 10Mb/s. The 9150DC edition incorporates most of the features of the high-performance 9150T, but is DC-powered, eliminating the need for AC wiring. For detailed information on LAN connectivity, please refer to page 21.
The 9150 supports Type II PCMCIA cards so that multiple radio interfaces are pos­sible. The 9150 also has dual-radio functionality. It can support several combina­tions of radio types to function as both a mini-controller and base station, access point and base station, or access point and mini-controller. For details, see “Radio Options” on page 7.
The 9150 Flash memory holds the boot code, configuration parameters and firm­ware. The 9150 Configuration program allows various parameter settings to be changed, added or deleted. The Flash can be reconfigured remotely via the network using a standard HTML Web Browser such as Netscape or MS Internet Explorer (for instructions, see Chapter 3: “9150 Main Configuration”).

Chapter 1: Introduction
Access Point Functions
1.3.1 Access Point Functions
As an access point connected to a wired network, the 9150 Wireless Gateway forms a communication link between Teklogix RF terminals or wireless access point clients and a Teklogix Network Controller or a host computer. It communicates over an IEEE 802.11b RF data link with terminals, and over a cable with the network controller or a host computer. The 9150 can be connected to the network through an Ethernet connection. The diagram in Figure 4.1 on page 65 illustrates a 9150 access point connection between a Teklogix 9400 Network Controller on Ethernet and IEEE 802.11 wireless devices.
Two 9150 Wireless Gateways can be used as an 802.11b bridge connecting two sep­arate wired networks. The 9150 can also be used as an 802.11b wireless access point to extend coverage area or for locations difficult to wire (see Figure 1.4 on page 10). For information on the 9150 as an access point, see “IEEE 802.11b Protocol” on page 8 and Chapter 4: “Access Point Configuration”.
1.3.2 Base Station Functions
As a base station or Remote Radio Module (RRM) connected to a wired network, the 9150 provides a link between the local area network and the wireless network consisting of Teklogix mobile terminals, and wireless base stations such as the 9150 Wireless Gateway. The 9150 and 9400 Network Controller (or host using a Teklogix Software Development Kit) communicate using the 9010 proprietary protocol with TCP/IP over Ethernet connectivity. Wlan protocol enables the wired 9150 to com­municate with 9150s without cable attachments (see Figure 5.1 on page 108).
For information on configuring the 9150 as a base station or RRM, see Chapter 5: “Base Station Configuration”. For Wlan, see “Wlan Protocol” on page 13.
1.3.3 Mini-Controller Functions
The 9150 is equipped with some emulation capabilities, allowing it to act as a mini­controller. When a 9150 is configured as a mini-controller, Teklogix terminals can emulate an ANSI, 5250 or 3274 terminal through the 9150 rather than through a 9400 Network Controller.
To configure the 9150 as a mini-controller, see Chapter 6: “Mini-Controller Con­figuration”. For a generalized system diagram, see Figure 6.1 on page 150.

The 9150 supports Type II PCMCIA cards so that multiple radio interfaces are possible. There is one internal and one external PC card slot available. The type of PCMCIA radio card installed in the 9150 is dependent on your wireless network. Currently supported radios are:
• TRX7370 Narrow Band DSP (available in either two level or four level modulation, with bit rates of 4800 b/s and 9600 b/s, or 9600 b/s and 19200 b/s, respectively).
• TekLAN 902 MHz DS Spread Spectrum (TRX7410).
• Lucent WaveLAN IEEE 802.11 DSSS 2.4 GHz (TRX7431 - up to 11Mb/s).
The 9150 can support several combinations of radio types, operating on different channels, to function as both a mini-controller and base station, access point and base station, or access point and mini-controller. The 902 MHz, 2.4 GHz (802.11 and TekLAN) and Narrow Band radios can be used in any combination, with the exception of dual TekLAN or dual Narrow Band radios.
Note: The 9150DC supports dual 802.11 radios, but not Narrow Band or
TekLAN 902 MHz radios. For details on the 9150DC, see page 22.
Important: The radio in the terminal must match the radio in the 9150 Wire-
less Gateway. If changing radio types in the 9150, DO NOT “hot swap” the PC cards: Turn the 9150 off before changing the radio.

1.5 Radio Protocols

RF protocols allow terminals to communicate with a base station by sharing the use of a radio channel in an efficient way. Teklogix systems use one of three types of RF protocols: the Teklogix Adaptive Polling/Contention protocol, the Teklogix Wireless LAN (Wlan) protocol, or the non-proprietary IEEE 802.11b protocol. When used as a base station, the 9150 uses either the Adaptive Polling/Contention protocol or the Wlan protocol. These protocols cannot be mixed on a single system. When used as an access point device, the 9150 employs the IEEE 802.11b protocol. The protocols are described in the following sections.

Chapter 1: Introduction
IEEE 802.11b Protocol
1.5.1 IEEE 802.11b Protocol
The IEEE 802.11b protocol is an OSI standard for Wireless Local Area Networks (WLANs). With this standard, any IEEE 802.11b radio can communicate with any other similarly-equipped device. However, IEEE 802.11b does not provide a stan­dard for a total WLAN system. IEEE 802.11b solely standardizes two communica­tions layers: Physical (PHY) and Medium Access Control (MAC). Three different PHY layer media are covered: 2.4 GHz Direct Sequence Spread Spectrum radio,
2.4 GHz Frequency Hopping Spread Spectrum radio, and infrared. Each station in a WLAN system has its own unique MAC address.
Important: Equipment using one physical medium (e.g. Frequency Hopping
IEEE 802.11b uses 2.4 GHz radios of relatively low power. The range is limited to no more than a hundred feet or so, depending on the conditions, and is usually restricted to “line of sight” operation. Therefore, most wireless networks need more than one coverage area, with terminals moving between the areas. To integrate those areas, systems using IEEE 802.11b protocol for their wireless networks require an IEEE 802.11b-equipped bridge device (or access point), such as the 9150 Wireless Gateway.
versus Direct Sequence) will not interoperate with equipment using a different physical medium.
Using bridging software, the 9150 Wireless Gateway enables communication between any wireless IEEE 802.11b-equipped stations and LAN stations operating on Ethernet. The 9150 itself is resident on the LAN and functions as a MAC bridge, providing transparent integration between the stations on the wireless and wired networks.
Each terminal is associated with one 9150. A frame from an RF terminal is sent to the 9150 that the terminal is associated with. The terminal puts a destination MAC address in the frame, which specifies a hardware address on the wired LAN side. Because the receiving 9150 is connected to an Ethernet network, it encapsulates the data in an Ethernet frame, including the destination MAC address specified by the terminal. The 9150 then sends the frame onto the physical network; the frame is picked up by whichever device is at the destination hardware address.
When sending frames from the LAN side, the sending device puts the MAC address of the terminal in the frame header. Whichever 9150 has that terminal associated with it, takes the frame and passes it over the RF to the terminal. By passing frames in this way, the 9150 is acting as a MAC bridge.

Chapter 1: Introduction
IEEE 802.11b Protocol
1.5.1.1 Inter-Access Point Protocol (IAPP)
The Inter-Access Point Protocol (IAPP) is an extension to the IEEE 802.11b proto­col. IAPP facilitates roaming of mobile stations across different Basic Service Sets (see Note below) and specifies how access points communicate with each other.
Note: A Basic Service Set (BSS) is a set of stations (terminals) controlled by a
single coordination function, in this case by the 9150 Wireless Gateway functioning as an access point within the terminals’ radio coverage area.
In a multiple-9150 system, IAPP informs the other 9150 Wireless Gateways when a new 9150 becomes active, and enables the awareness of the 9150s of each other. With IAPP, an IEEE 802.11b system can operate on one or more channels, with terminals moving between the 9150s. Although each terminal is associated with one 9150, it can re-associate with another 9150 to maintain uninterrupted communica­tions. The newly-associated 9150 will receive the terminal’s data frames and pass them onto the LAN. Returning frames are no longer accepted by the original 9150, which has disassociated from that terminal. The returning frames are now accepted by the newly-associated 9150 and passed over the RF to the terminal.
1.5.1.2 Psion Teklogix’ 802.IQ Protocol
802.IQ is a Psion Teklogix proprietary optimized protocol that enables terminals to operate on a wireless LAN in a network that supports both TCP/IP and 802.IQ pro­tocol simultaneously. 802.IQ protocol is available in two versions: 802.IQv1 and
802.IQv2. The 9150 can support both versions of the protocol at the same time (ter­minals must use only one).
802.IQv1 protocol is a wireless LAN routing scheme that provides greater perfor­mance in an 802.11b wireless network than is possible with TCP/IP routing. The 9150 bridges the 802.IQv1 wireless and TCP/IP wired networks. A terminal can communicate with the 9150 access point using either TCP/IP or 802.IQv1 protocol, which makes possible a system with dual-operability.
802.IQv2 protocol is an enhanced version of the 802.IQv1 protocol that transports packets over the UDP layer. It provides all the 802.IQv1 functionality, with the added features of software upgrade capability over RF, the ability to add third-party access points between controllers and terminals, and integration into the MapRF system if desired.
For detailed information on configuring the 9150 as an 802.IQv1 access point, see “802.IQ Version 1 Configuration Menu” on page 68. For information on configur­ing the 9150 as an 802.IQv2 mini-controller, see “802.IQ V2 Features Menu” on page 201. Please see Figure 1.4 on page 10 for a generalized system diagram.

IEEE 802.11b Protocol
1.5.1.3 802.1X Security
The 9150 can perform as part of an 802.1X system.
802.1X is an IEEE standard approved in June 2001 that enables authentication and key management for IEEE 802 local-area networks. Originally developed for wired networks, 802.1X defines the changes necessary to the operation of a MAC bridge in order to support port-based access control.
802.1X provides a means for MAC bridges, such as the 9150 in access point mode, to block packet traffic from individual ports until appropriate authentication for the port has occurred. For authentication, 802.1X defines a protocol that is used to encapsulate higher layer authentication exchanges for transport over IEEE 802 LANs.
The 802.1X standard defines:
• How MAC bridges perform port based access control
• A encapsulation protocol for higher layer authentication
• A method for delivering encryption key data from access point to station
802.1X does not define encryption methods or authentication methods.
Parts Of An 802.1X System
There are three parts to an 802.1X system:
Wireless Link
Supplicant
• Supplicant
The “supplicant” is a network device that must be authenticated before its packet traffic will be forwarded to the wired network. The supplicant
Authenticator
Wired Link
Authentication Server
Teklogix 9150 Wireless Gateway User Manual 11
Page 28
Chapter 1: Introduction
IEEE 802.11b Protocol
connects to the authenticator, which communicates on its behalf to the authentication server.
The Psion Teklogix 7035, 8255, and 8260 terminals can act as supplicants.
• Authenticator
The “authenticator” is a MAC bridge that blocks packets originating from supplicants from being bridged to the wired network until the supplicant has been successfully authenticated. The authenticator does not authenticate the supplicant but instead relays an authentication exchange between the supplicant and the authentication server using an appropriate transport pro­tocol for each.
The Psion Teklogix 9150 access point can act as an authenticator.
• Authentication Server
The “authentication server” is responsible for authenticating the supplicant upon request from the authenticator.
Authentication in an 802.1X system is performed using the Extensible Authentica­tion Protocol (EAP). Originally developed for PPP, EAP is a simple protocol that defines a basic authentication messaging exchange between two parties. EAP is extensible because it allows for support of different authentication methods.
The EAP messaging exchange takes place between the supplicant and the authenti­cation server. The supplicant sends and receives EAP messages encapsulated in the EAPOL protocol, while the authentication server typically sends and receives EAP messages encapsulated in the RADIUS protocol. Between them, the authenticator accepts and repackages the EAP messages in the appropriate protocol for delivery to either the supplicant or the authentication server.
Although the authenticator does not actively participate in EAP messaging, it does passively monitor the EAP exchange between a supplicant and authentication server. When it receives indication that the supplicant has been successfully authenticated, the authenticator unblocks the bridge port for the supplicant, which is then accepted as part of the wireless network.
Psion Teklogix devices use the MD5-Challenge authentication method.

Chapter 1: Introduction
Adaptive Polling/Contention Protocol
1.5.2 Adaptive Polling/Contention Protocol
The Adaptive Polling/Contention protocol is always used on Narrow Band radio systems with baud rates of up to 19.2 kb/s, and may also be used on Spread Spec­trum systems at higher rates.
Terminals operating with this protocol do not transmit unless they receive polls from the 9150. Terminals are generally polled en masse. Following each poll, groups of terminals are assigned response windows in which they may respond to the poll. If a “collision” occurs – more than one terminal attempts to respond in a particular window – the 9150 that is polling divides and reassigns that group until the colliding terminals can respond without a collision.
Adaptive features of this protocol allow the response windows to be adjusted to accommodate high or low RF traffic conditions, and to prevent data from being queued too long when a particular terminal has a burst of data to send or receive.
Systems using adaptive polling/contention can use the cellular option so that terminal operators can roam the site, maintaining uninterrupted communication as they pass between coverage areas. If cellular base is not enabled, a “RESET: Press Enter” message appears on the terminal screen each time an operator moves from one base station coverage area to another.
1.5.3 Wlan Protocol
The Wlan (Wireless LAN) protocol is used only on Spread Spectrum radio systems at bit rates of 122kb/s and higher. The Wlan protocol allows base stations to be added to a system without cable connections. A Wlan system consists of a minimum of one wired base station and zero or more wireless base stations. It can operate on either one channel – usually the case – or on multiple channels.
When a Wlan system is operating, base stations do not send out polls. Instead, both wired and wireless base stations regularly broadcast routing information, indicating the available routes back to the controller. Both terminals and wireless base stations receive these broadcasts, determine the best communication route, and send their messages. If a better route becomes available, the terminal or wireless base will change communication paths.
Teklogix 9150 Wireless Gateway User Manual 13
Page 30
Chapter 1: Introduction
Wlan Protocol
Only one base station or terminal may transmit at one time. When the channel is clear, a combination of preset priorities and random choices determines who “goes next”. Even if two transmitters attempt to send at the same time, message acknowledgements and retransmissions prevent any data from being lost.
Terminals moving through the Wlan communicate with the base stations that provide the best communication path to a wired base station. If multiple channels are used, the terminal looks for a better channel only if it cannot find an acceptable path back on its current channel.
For detailed information on configuring the 9150 as a base station, please see Chapter 5: “Base Station Configuration”. For a generalized system diagram, see Figure 1.5.

Chapter 2: Installation Requirements
Choosing The Right Location
Warning: The 9150 must be installed by qualified Psion Teklogix personnel.

2.1 Choosing The Right Location

Typically, Psion Teklogix conducts a site survey in the plant and then recommends the preferred locations for the 9150s. These locations provide good radio coverage, minimize the distance to the host computer or network controller, and meet the environmental requirements.
2.1.1 Environment
2.1.1.1 9150 Wireless Gateway
The 9150 should be located in a well-ventilated area and should be protected from extreme temperature fluctuations (i.e. direct heater output, shipping doors or direct sunlight). If a protective cover is required, it must have enough ventilation to maintain the 9150’s surface at or near room temperature.
Refer to Chapter 8: “Specifications” for a more detailed description of environmen­tal requirements. Keep in mind that the long term stability of this equipment will be enhanced if the environmental conditions are less severe than those listed in this manual.
The 9150 should be situated away from the path of vehicles and free from water or dust spray. The 9150 should only be mounted in the upright position, as shown in Figure 2.1 on page 18. This orientation minimizes the risk of water entering the 9150, should the unit accidentally be sprayed.
The 9150 is attached to a vertical surface using four fasteners on the rear plate (type of fasteners are dependent on mounting surface). The top two holes in the rear plate are slots, allowing the unit to be hung in position before the remaining bolts are installed, thus easing installation. The bolts used for installation are SAE 1/4-20.

Power And Antenna Cables
2.1.3 Power And Antenna Cables
2.1.3.1 Power
To prevent accidental disconnection and stress on the 9150, antenna and power cables should be secured within 30 cm of the unit. Secure the cables with ties to the cable tie mounts on the 9150 (see Figure 2.1 on page 18). A single phase power outlet (range 100 to 240 VAC rated 1.0A minimum) should be installed within one metre (3.1 feet) of the 9150. The 9150 automatically adjusts to input within that power range. The power cable is removable and is available in the power type spe­cific to your location.
To eliminate the need for AC wiring, the 9150DC Wireless Gateway is powered over its Ethernet connection. For detailed information, please see page 22.
Warning: To avoid electric shock, the power cord protective grounding
conductor must always be connected to ground.
2.1.3.2 Antennas
The type of antenna required for each installation depends on the coverage require­ments and the frequencies used. There are several omnidirectional antennas avail­able from Psion Teklogix. Generally, a site survey determines the appropriate antenna. Psion Teklogix can also provide special, directional antennas. Consult Psion Teklogix service personnel for more information.
Warning: Equipment requires professional installation. The installer is
responsible for ensuring that the 2.4 GHz antennas, 24dBi grid dish (P/N 21267) and 24dBi dish (P/N 21265), are used exclusively for fixed, point-to-point operation; and fixed, point-to-point operation excludes the use of point-to-multipoint system, omni­directional applications, and multiple co-located intentional radia­tors transmitting the same information. The maximum output power from the radio transmitter is 32 mW.

Chapter 2: Installation Requirements
Power And Antenna Cables
Warning: Never operate the 9150 without a suitable antenna or a dummy load.
Connection to Outdoor Antenna: Outdoor antenna to be earthed in accordance with International Standard EN 50083-1 (1993), “Cabled Distribution Systems for Television and Sound Signals ­Safety Requirements”. The antenna must be installed by a qualified service person and installed according to local electrical installation codes. The antenna should be located such that it is always at least 15 ft (4.6 m) high and 10 ft (3 m) from the user and other people working in the area.
Warning: For RF safety considerations, users are not allowed to approach
close to the antenna.
Psion Teklogix supplies the coaxial cable required to connect the 9150 to the antenna. When determining the location of the antenna, the coverage requirements of the antenna are considered in conjunction with the environmental requirements of the 9150.
The coaxial cable must be routed and secured using wire anchors and/or coaxial nail clips. A few extra inches of cable are required near the antenna and the 9150 to make disconnection easier.

2.2.2 LAN Installation: Overview
Because the 9150 provides Ethernet connectivity, it can be added to an existing LAN. Generally, LAN installations are handled with the help of the network administrators, as they are familiar with their network and its configuration.
Once the 9150 is installed, connected and powered on, the system administrator can access the unit to check the configuration and to assign the 9150 its unique IP address. This may be done through the Console port or through the network (see “Connecting
Teklogix 9150 Wireless Gateway User Manual 21
Page 38
Chapter 2: Installation Requirements
LAN Installation: Ethernet
A Video Display Terminal” on page 28 and “Changing The Configuration With A Web Browser” on page 28). Subsequent changes in the network, such as the addition of stations or users, would also require that the 9150 configuration be changed.
Important: Once the 9150 is configured and rebooted the first time, the DHCP
or Bootp option should be disabled—unless the 9150 obtains its IP address from a server, or the system administrator intends to update the software through bootp. For detailed information, see “Network Interface Configuration Protocol” on page 54.
2.2.3 LAN Installation: Ethernet
2.2.3.1 9150T Wireless Gateway
The 9150T is a high-performance controller that supports 100Mb/s Fast Ethernet LANs, as well as 10Mb/s, with both full and half duplex operation. It comes equipped with:
• 10BaseT/100BaseT card (using a category-5 twisted pair cable, an RJ-45 connector, running at a rate of 10 or 100Mb/s).
Note: The 9150T does not support any connection type other than Ethernet
10BaseT and 100BaseT.
See Figure 2.2 on page 21 for the connector locations. Since these ports are auto­selecting, jumper or configuration settings are not required. The maximum packet size supported over the network is 1500 bytes. This parameter is not set at the 9150, but should be set at the host. For a description of port pinouts, please refer to Appen­dix B: “Port Pinouts And Cable Diagrams”.
2.2.3.2 9150DC Wireless Gateway
The 9150DC incorporates most of the features of the 9150T. However, while the 9150T is AC-powered, the 9150DC Wireless Gateway is DC-powered, eliminating the need for AC wiring. The 9150DC is powered through a Category 5 ethernet cable that carries power and data signals simultaneously.
The 9150DC is connected to the 9100 PowerBaseT, a remote power module that inserts 48VDC power on the spare conductors of the ethernet cable to the 9150DC (for detailed information on the 9100, see page 24; for a system diagram, see
Teklogix 9150 Wireless Gateway User Manual

Figure 2.5 on page 25). Inside the 9150DC, a DC/DC converter is used to step down the +48 V provided by the 9100 to the +5 V required to power the main components of the gateway.
The 9150DC may also be powered via the Auxiliary Supply (48 V DC) power jack, which is adjacent to the ethernet RJ-45 connector (see Figure 2.3). For a description of RJ-45 port pinouts, refer to Appendix B: “Port Pinouts And Cable Diagrams”.

The 9150DC supports dual 802.11 radios, but does not support Narrow Band or TekLAN 902 MHz radios.
2.2.3.3 Ethernet Cabling
The maximum cable segment length allowed between repeaters for both the 9150T and 9150DC (10BaseT/100BaseT Ethernet cabling) is 100 m.
Note: For the 9150DC (see “Important” note on page 24), this cable length is
measured from hub to 9150, including the mid-span insertion of the 9100 PowerBaseT.
Important: For Main Logic Board (MLB) P/N 30183-301 Rev F only: When
connecting the RJ-45 Ethernet cable to the 9150T (AC power ver­sion), ensure that the snap-on ferrite for cables (P/N 97776) is placed on the cable as closely as possible to the RJ-45 jack. To determine which version of the MLB is resident in your 9150, please contact Psion Teklogix Support Services (see page A-1).

2.2.3.4 9100 PowerBaseT Mid-Span Power Supply
Overview
The 9100 PowerBaseT module is designed to provide power over Ethernet and may be referred to as a “mid-span power supply” in that it intercepts the Ethernet cables between a hub/switch and the DC-powered 9150DC, as illustrated in Figure 2.5 on page 25. The 9100 has an internal, universal DC power to each of its independent Data + 48V output Ports, following successful detection of a suitable powered device (a 9150DC). The Resistor Detection method is employed for this purpose, following application of power to the 9100, or connec­tion of a powered device to a powered-on Port. The 9100 determines whether each connected device needs to be powered or not by determining if there is a signature resistor in the powered device between the 4/5 and 7/8 “spare” wire pairs. Subse­quent disconnection of such a device is also detected. There are four identical, inde­pendent resistor/transistor networks, one for each output port. 48VDC is supplied via the unused pairs of a standard Ethernet Category 5 cable, while the Ethernet data lines (4 of the 8 conductors in the cable) are passed through the 9100 to the 9150DC. The 9150DC can accept power via either the unused pairs, or via the data pairs of a 10/100BaseT system connected to a suitable Power Over Ethernet switch/hub.
AC/48VDC power supply and routes
Important: The 9100 does not contain any transceivers (the data signals are
passed through) and is therefore subject to the 100 m cable length limitation (including the cable from the hub/switch to the 9100 PowerBaseT and any subsequent length added to the 9150DC).
The 9100 PowerBaseT provides power for up to four 9150DCs (13 Watts per channel maximum), connected by twisted pair cables up to 100 m in length. See page 216 for power specifications.

Functions
The 9100 PowerBaseT delivers 13 Watts per port for a total of 52 Watts. Power sup­plied to each of the four Ethernet ports is protected from over-voltage and current limiting within the power supply by the 9100’s microcontroller. Its primary functions are:
1. Resistor Detection (described in Overview on page 24).
2. Fault Monitoring (page 207).
3. Power Monitoring (page 208).
4. Diagnostics and Status Reporting (page 208).
Status Indicators
The LEDs present at each port on the front panel of the 9100 (Figure 2.4 on page

2.2.5 Connecting A Video Display Terminal
An ANSI compatible video display terminal (e.g., DEC VT220 or higher), or a PC running terminal emulation, is used for diagnostic purposes and to configure the 9150’s IP address for the first time (necessary before the 9150 can be accessed using a Web Browser; see “Configuring The IP Address” on page 31).
The terminal is connected to the port labelled “Console” on the 9150 (see Figure 2.2 on page 21). This port is normally set to operate at 19,200 b/s, with 8 bits, 1 stop bit, and no parity. To comply with Part 15 of the FCC rules for a Class B computing device, only the cable supplied (Part no. 19387) should be used.

2.3 Changing The Configuration With A Web Browser

The 9150 Flash memory can be reconfigured remotely via the network using a stan­dard HTML Web Browser such as Netscape Navigator (version 4.05 or later) or MS Internet Explorer (version 4.0 or later). See Chapter 3: “9150 Main Configuration” for instructions on changing the parameters and general configuration settings.
For configuration information on setting up the 9150 as an access point device, refer to Chapter 4: “Access Point Configuration”.
For configuration information on setting up the 9150 as a base station, refer to Chapter 5: “Base Station Configuration”.

Configuration Main Menu

3.1 Configuration Main Menu

The 9150’s flash memory can be reconfigured remotely via the network using a standard HTML web browser such as Netscape Navigator (version 4.05 or later) or MS Internet Explorer (version 4.0 or later).
Note: To ensure that the 9150 configuration screens appear properly when
using Netscape Navigator, in your browser go to Edit/Preferences/ Appearance/Colors. Make sure that the box for “Always use my colors, overriding document” is NOT checked.
The 9150 Configuration program allows various configuration parameter settings to be changed, added or deleted.
Important: The 9150 must be warm-rebooted after parameter changes are
made, including configuring the IP address (see below), in order for the changes to take effect. For details, see “Reboot Unit” on page 62.

3.2 Configuring The IP Address

Before the configuration menus can be accessed using your web browser, the 9150 must be assigned an IP address using a PC console connection. Virtually any PC can be connected to the console port of the 9150, provided that the PC has a serial port and a terminal communication program such as the Windows utility or Procomm such as VT220 or higher. Cable no. 19387 should be used to connect the PC to the
9150. Make sure the communications settings on your PC are set to 8 bits, 1 stop, no parity, and that the bit rate of the serial port matches that of the 9150 console port (19,200 b/s).
After the PC is attached and turned on, press the <RETURN> key several times until the “>” prompt appears. The commands used to configure IP addresses are described here. For the command to flash upgrade the 9150 software using TFTP, please refer to page 55.
If your system uses a DHCP or BOOTP server to assign IP addresses, make sure that the appropriate option is enabled (see “Network Interface Configuration Proto­col” on page 54). Once enabled, and the 9150 is rebooted, you will be able to access the 9150 configuration menus through the Web Browser, using the IP address

Accessing The Menus

3.3 Accessing The Menus

When the web browser is pointed to the 9150’s IP address, a name and password dialog box appears. The password is comprised of alphanumeric characters and is case-sensitive. If you change the password (see “Users” on page 41), set all 9150s to the same password, and write it down in a secure place.
A default user name “user” and the password “123456” are created on 9150 system startup if no users are already configured. You can use the default to enter the Configuration Main Menu for the first time. For security, change this default name and password immediately after entering the configuration menus. Should you acci­dentally delete your user names, re-booting the 9150 will re-create the default name and password so that you can get back in to the unit.
After the 9150 accepts the password, it displays the Configuration Main Menu. The 9150 software automatically detects the system information of the unit, and most of the parameters have already been properly configured for each site.
Warning: Parameters should not be altered without a clear understanding of
how they operate. Parameters that are incorrectly set can increase response time or cause communication difficulties.
• To highlight and move through the different options, use the <TAB> key or mouse pointer.
• To view and select the items in the listboxes, either press the <UP> or <DOWN> arrow keys or click on the arrow at the side of the menu and highlight the item.
• To enter the related configuration sub-menu dialog box, highlight “Configure” and either press <ENTER> or click on the “Configure” button.
• Where string entry parameters are given in the menus, changes are keyed in. Numerical parameters can be entered as hexadecimal values. Precede hexadecimal values with “0x”.
• To leave a menu page, select either the <OK> or <Cancel> button at the bottom of the page. Selecting <OK> will save your changes and exit the page, while selecting <Cancel> will exit the page without saving the changes.
Important: Do not use the web browser’s <Back> button to leave a page.

The pull-down menu shown for the Interfaces option indicates which interfaces have been detected in use by the 9150.
3.4.1.1 10BaseT Ethernet
For the selection 10BaseT Ethernet, entering the “Configure” dialog box will open the Onboard Ethernet Parameters page for that Ethernet connection, which shows the 9150’s physical (hardware) address and IP address parameters.
Physical Address
A unique Physical Address is assigned by Psion Teklogix personnel for each 9150. The values entered for this parameter are presented in hexadecimal in descending order beginning with the MSB (Most Significant Byte), the highest value, and ending with the LSB (Least Significant Byte), the lowest value. The allowable value for each field ranges from 00 to FF.
Warning: It is not advisable to modify the Physical Address. However, if
these values are to be changed, the Network Administrator must assign a unique address to each Ethernet station on the network, including all 9150s.

IP Parameters
Each 9150 that is connected to a local network has a unique IP address designated for it. The 10BaseT Ethernet IP Parameters used to assign the IP address are accessed by entering the “Configure” dialog box.
IP Address
The Current IP Address shown in the read-only field is the IP address currently set on the 9150. The Default IP Address text box allows you to change the value of the IP address.
The IP address must be a unique value on the network, so that each 9150 in your system can be identified. The acceptable value ranges from 0.0.0.0 to
239.255.255.255.
Note: The value 255.255.255.255 is reserved for the broadcast address.
Subnet Mask
The Current Subnet Mask shown in the read-only field is the subnet mask currently set on the 9150. The Default Subnet Mask text box allows you to change the value of the subnet mask.
The 9150 uses the Subnet Mask, its own IP address, and the destination IP address to determine if a packet should be sent on the local network or to a remote segment. If the destination is found on the local network, the packet is sent directly to its desti­nation. If the destination resides on a remote network, the packet is routed to the gateway. Enter your subnet mask in “xxx.xxx.xxx.xxx” notation.
Important: The maximum packet size supported is 1500 bytes. This parame-
ter is not set at the 9150, but should be set at the host.
The acceptable values range from 0.0.0.0 to 255.255.255.255.

SNMP
Individual names and their assigned passwords may be changed or deleted in the “Configure” dialog box for this option by selecting the name in the listbox and then opening the “Configure” dialog box.
3.4.3 SNMP
SNMP (Simple Network Management Protocol) is the protocol that governs network management and the monitoring of network devices and their functions, including those in MapRF systems.
3.4.3.1 MapRF
The 9150 is fully compatible with Psion Teklogix’ MapRF network management software. For complete details on MapRF, please refer to the MapRF User Guide. Manual configuration of a 9150 in a MapRF system is minimal. The following parameters must be correctly configured:
• “10BaseT Ethernet” on page 36 and “100BaseT Ethernet” on page 38. The IP address, default gateway and subnet mask must be correctly configured for MapRF, either directly in the web pages or dynamically through DHCP/Bootp (see “Network Interface Configuration Protocol” on page
54).
• SNMP must be enabled (see page 44).
Some parameters may need to be configured, depending on your firmware version. These are listed below. To determine whether the firmware version in your 9150 already supports these parameters through SNMP, please contact Psion Teklogix Support Services (see Appendix A: “Support Services And Worldwide Offices” ).
• “Serial Ports Parameters” on page 58.
• “Mobile IP Configuration” on page 99.
• “TekLAN Parameters” on page 110.

Enabled
When this parameter is enabled (√), the 9150 will respond to SNMP inquiries and provide SNMP information. For the 9150 to operate with MapRF, the checkbox must be enabled. The default setting is enabled.
3.4.3.3 Enable Proxy for non-IP terminals
When this parameter is enabled (√), the 9150 acts as a proxy within the MapRF manager, for managing terminals without IP addresses. This option should be used only when the 9150 is acting as the Cellular Master (mini-controller).
3.4.3.4 Proxy throttling
To ensure that increased radio traffic due to the 9150 acting as proxy does not create a problem, the amount of traffic can be controlled by setting it to 100, 500, or 1000 bytes per second. The default is Disabled.
3.4.3.5 SNMP Communities and Trap Receivers
These parameter settings allow the network administrator to define the network environment and determine the type of access allowed (read_only or read_write) for each area name and IP address. The Name entries should be of 7-bit, US-ASCII character type and not more than 255 characters. The trapDest IP addresses deter­mine which SNMP manager’s stations will receive SNMP Traps from the 9150.

Redundancy
The 9150 sends the “Cold Start” Trap on reboot or power up.
Important: Any parameters that are changed in the SNMP Communities and
Trap Receivers menu must also be changed in the MapRF manager.
3.4.4 Redundancy
The Redundancy Parameters “Configure” page, entered from the Configuration Main Menu page, allows the user to set various options for the redundant (backup)
operation of the 9150.
This feature enables two similarly-configured 9150s to operate in parallel. One 9150 is designated as the primary 9150, and manages communication to the rest of the Teklogix system. The other 9150 is designated as the secondary 9150, and remains idle. Both 9150s communicate with one or two arbiters, extremely stable devices on the network, such as a host, which serve as a reference for the status of the network itself.
Both the primary and secondary 9150s must be connected to the network, and each 9150 is aware of the other’s IP address. The secondary 9150 polls the primary 9150, and the primary 9150 responds, exchanging information about their status. There may not be more than one secondary 9150.
If the secondary 9150 cannot communicate with the primary 9150, but can commu­nicate with one or both arbiters, it assumes that the primary 9150 is not working. It then becomes the primary and assumes control of the Teklogix backbone on the network.
When the first 9150 comes online again, it assumes secondary status while the second 9150 continues as the primary. If the 9150s cannot communicate with the arbiter, they assume that the network is not working.
Teklogix 9150 Wireless Gateway User Manual 45
Page 62
Chapter 3: 9150 Main Configuration
Redundancy
Important: Both 9150s must be configured identically, with the exception of
their unique IP addresses and the Backup IP Address parameter, which is the IP address of the other 9150.
Note: When control of the Teklogix system is passed from one 9150 to the other,
sessions between hosts and terminals are closed, and terminals and bases are reset.
Enabled
When this checkbox is enabled (√), the 9150 uses the Redundancy feature. A second 9150, appropriately configured, and arbiters must be present on the network for the feature to operate properly.
The default is disabled.
Preferred Primary
This parameter decides which 9150 becomes primary if both want to be primary. The checkbox should be enabled (

√) in only one of the redundant pair of 9150s.
Page 63
Chapter 3: 9150 Main Configuration
Redundancy
Backup IP Address
The Backup IP Address parameter contains the address of the other 9150 with which this 9150 communicates. The default value is 0.0.0.0.
Note: The Backup IP address cannot be the same as the Alias IP address
(page 48).
Poll Interval, Poll Timeout And Poll Tries Parameters
The next three parameters are closely related. When this 9150 acts as the secondary device, it polls the primary 9150 at intervals specified by the Poll Interval parame­ter. After each poll, this 9150 waits for a reply for the length of time specified by the Poll Timeout parameter. If there is no reply during this time period, the 9150 sends another poll to the other 9150. The total number of polls sent while this 9150 waits for the response is specified by the Poll Tries parameter. If no response is received to the polls, the 9150 then pings the arbiter(s) to determine the status of the network.
Poll Interval
This parameter contains the interval, in seconds, at which this 9150 communicates with the other 9150.
The range of values is 1 to 9999, the default is 10.
Poll Timeout
This parameter contains the interval, in seconds, during which this 9150 waits for a reply after sending a poll to the other 9150. If there is no reply, it sends another poll to the other 9150.
The range of values is 1 to 9999, the default is 2.
Poll Tries
This parameter contains the number of times this 9150 will re-send a poll to the other 9150, before assuming that it cannot be reached.
The usable range of values is 2 to 7, the default is 3. The value can go as high as 9.
Teklogix 9150 Wireless Gateway User Manual 47
Page 64
Chapter 3: 9150 Main Configuration
Redundancy
Alias IP Address
This parameter contains the alias IP address, identical for both this and the other 9150 in the redundancy system. The primary 9150 presents the alias IP address to the network, as well as its own unique IP address. The secondary 9150 only presents its unique IP address to the network.
When the secondary 9150 becomes the primary, it starts to use the alias IP address as well as its unique address, while the other 9150 stops using the alias IP address.
Wirele s s devices in the system which communicate directly with the Teklogix network controller’s IP address, such as terminals using TCP Direct, may communi­cate with the alias IP address. They will then communicate with whichever of the two redundant 9150s is the primary.
This address must be the same on both the primary and secondary 9150.
The default address is 0.0.0.0.
Note: The Alias IP address cannot be the same as the Backup IP address
(page 47).
Arbiter 1 IP Address
This parameter contains the address of a device on the network which is known to be reliable. Both 9150s ping this device; if they receive no reply, they ping Arbiter 2 if so configured (see page 48), otherwise they assume that the network is not operat­ing. This address should be the same on both the primary and secondary 9150s.
Arbiter 1 must always be configured when Redundancy is enabled. The default value is the loop-back address 127.0.0.1.
Arbiter 2 IP Address
This parameter contains the address of an optional second device on the network which is known to be reliable. Both 9150s ping this device if they receive no reply from Arbiter 1. If they receive no reply from Arbiter 2, they assume that the network is not operating. This address should be the same on both the primary and secondary 9150s. If the default address is configured, Arbiter 2 won’t be used in the protocol.

3.4.5 SNTP
SNTP (Simple Network Time Protocol) is the protocol that enables the network to maintain an accurate system time. The SNTP Parameters “Configure” page, entered from the Configuration Main Menu page, allows the user to set the options.
Enabled
When this checkbox is enabled (√), the 9150 automatically sends requests to the SNTP server to retrieve the time in GMT (Greenwich Mean Time) format. The 9150 then sets the current local time using the Time Zone Offset value (see page 49).
SNTP
The default is enabled.
Server Address
This parameter contains the IP address of the SNTP server. If the server address is specified, the 9150 sends unicast messages to the server to retrieve the time. If the address is not specified (i.e. 0.0.0.0.), the 9150 retrieves the broadcast messages.
The default value is 0.0.0.0.
Refresh Rate
This parameter contains the interval, in minutes, at which the 9150 retrieves the time. The range of values is 1 to 1440 minutes. The default value is 60.
Time Zone Offset
The Time Zone Offset is the difference between the GMT and the local time where the 9150 is located. If you are not sure of your time zone offset, you can get the GMT by using the console command “
?T ” five minutes after booting up the 9150.

TCP/IP Parameters
The 9150 will retrieve the GMT and you can determine the offset value.
The range of values is -1339 to 1339 minutes. The default value is -240. (This default represents Eastern Standard Time, Canada, with Daylight Saving.)
Note: The 9150 does not automatically compensate for Daylight Saving time.
3.4.6 TCP/IP Parameters
If the 9150 is situated on a wired network, it uses TCP/IP. A Routing Table, Host Table, DHCP, Bootp, and DNS options are available to resolve IP addressing issues.
Note: The term host in this context refers to any device with an IP address,
including parts of the Teklogix system such as controllers, the 9150, and associated base stations.
This use of host is common in the networking field. It should be distinguished from Psion Teklogix’s use of host versus terminal.

TCP/IP Parameters
3.4.6.3 Network Interface Configuration Protocol
The 9150 has designated default IP addresses for itself and the network Gateway. Alternatively, the IP address of the 9150 can be assigned by either a DHCP Server or BOOTP Server, if one is appropriately configured on the network.
If either the DHCP or BOOTP option is chosen from the Network Interface Config- uration Protocol drop-down list, the 9150 will broadcast a request to the appropriate server, as described in the following sections.
The default setting is None.
Important: Once the 9150 is configured and rebooted the first time, the
Network Interface Configuration Protocol parameter should be disabled (set to None), unless the 9150 obtains its IP address from a DHCP or bootp server, or unless the system administrator intends to update the software through bootp.
DHCP
The Dynamic Host Configuration Protocol provides a mechanism for allocating IP addresses dynamically so that addresses can be reused when hosts no longer require them, and also ensures that a particular address is not duplicated. The 9150 can obtain the following parameters from an appropriately configured DHCP Server: IP address, subnet mask, and IP address lease time (see DHCP Lease Time on page 55). The DNS Domain Name/Server IP addresses (see page 56) and SNTP Server IP address (see page 49) will also be requested from the DHCP Server.
Teklogix 9150 Wireless Gateway User Manual
54
Page 71
Chapter 3: 9150 Main Configuration
TCP/IP Parameters
Select DHCP for the 9150 to automatically broadcast a request for DHCP­configured addresses to all hosts on the local Ethernet network.
BOOTP
The primary purpose of the Bootstrap Protocol (BOOTP) is to assign a designated IP address to the appropriate 9150 on the network, and to update the 9150 software.
When the BOOTP option is selected from the Network Interface Configuration Pro- tocol drop-down list, the 9150 automatically broadcasts a request for IP address, subnet mask, and flash image file name, to all hosts on the local Ethernet network, including the Wireless Distribution System (WDS) links.
BOOTP servers search the bootptab files for a hardware address match for the 9150 that initiated the request for address. (Bootptab files list each hardware address with a corresponding IP address, and the flash image file.) The host with a matching hard­ware address in its bootp table replies to the request, sending the appropriate IP address and, if needed, the image file to the 9150.
Software Upgrade Using TFTP
The 9150 software may be upgraded by using a TFTP server instead of BOOTP. Contact the TFTP server and download the new image file by connecting the 9150 to a PC console (for details refer to page 31) and entering the following command line:
>net tftp <servername><imagefile>
The image file will be loaded after the 9150 is rebooted.
Note: This command is available for all version C and later releases of
software, and for version B55. Do not use if B52 is the current version of the software.
DHCP Lease Time
This parameter defines the length of time (in days) that the 9150 is requesting for the lease on its IP address and subnet mask. The default setting is 0 (zero), which requests the maximum lease time configured at the DHCP Server.
Teklogix 9150 Wireless Gateway User Manual 55

Chapter 3: 9150 Main Configuration
TCP/IP Parameters
Default Gateway Address
The Default Gateway Address creates an identifiable communication link between the 9150 and a network other than the one to which the 9150 is directly wired. The Gateway Address shown in the read-only field is the address currently assigned by the network administrator. The text box allows you to change the value of the address.
The acceptable values for the Default Gateway IP address range from 0.0.0.0 to
239.255.255.255.
Note: Setting the Gateway IP Address to 0.0.0.0 disables this feature.
A communication link will not exist between sub-networks.
3.4.6.4 DNS
Domain Name System allows users to locate destinations on the TCP/IP network by domain (host) name. The DNS server maintains a database of host names and their corresponding IP addresses. For example, if the server was presented with the name “www.teklogix.com”, it would return the IP address: “207.219.2.3”.
DNS Resolver Enabled
When this parameter is enabled (√), the 9150 will use the DNS Name Server identi- fied by the IP address entered in the DNS Name Server parameter.
DNS Default Domain
This is the default domain name for this 9150.

This parameter accesses the 802.IQv1 sub-screen that enables Psion Teklogix’ pro­prietary enhanced 802.11b protocol, as described in “802.IQ v1 Sub-Screen”, below, and in “Psion Teklogix’ 802.IQ Protocol” on page 9. For information on 802.IQv2, please refer to “802.IQ Version 2 Configuration” on page 201.
802.IQ v1 Sub-Screen
802.IQ is an optimized proprietary Psion Teklogix protocol that enables terminals to operate on a wireless LAN in a network that supports both TCP/IP and 802.IQ pro­tocol simultaneously.
802.IQv1 protocol is a wireless LAN protocol that provides greater performance in an 802.11b wireless network than is possible with TCP/IP.
The 9150 bridges the 802.IQv1 wireless and TCP/IP wired networks. A terminal can communicate with the 9150 access point using either TCP/IP or 802.IQv1 protocol.
Important: 802.IQ should only be enabled on wired 9150s.
Do not configure 802.IQ on wired 9150s bridging networks, since
802.IQ beacons would be sent through the WDS link from one network to the other (see “Wireless Distribution System (WDS) Configuration” on page 76).
The 802.IQv1 sub-screen is entered from the 802.IQ version 1 Configuration menu on the IEEE 802.11 Direct Sequence Radio Parameters page.

Auto Startup
This parameter enables ( √ ) 802.IQ immediately when the 9150 is rebooted. When the 9150 is operating as a base station under a network controller or a 9150 mini­controller, this parameter must be disabled.
The default value is disabled.
Important: If Auto Startup is set incorrectly, terminals may not operate correctly.
Beacon Period
An 802.IQ beacon is a broadcast sent out to all 802.IQ-enabled terminals. The beacon allows terminals to determine when they have roamed between base sta­tions. It enables a terminal to determine whether or not the base station or controller
Teklogix 9150 Wireless Gateway User Manual 69

was rebooted and, if so, how to recover. If the controller was rebooted, the terminal closes all sessions and fully re-initializes. If the base station was rebooted, or if the terminal moved to a different 9150, a warm initialize is done (no data will be lost).
The Beacon Period parameter acceptable value ranges from 1 to 20 seconds. The default value is 2.
Terminal Offline Timeout
This parameter sets the time (in minutes) before the 802.IQ task on the 9150 will send an offline message to the cellular master declaring the terminal offline.
The acceptable value ranges from 1 to 240. The default value is 5.
4.2.1.3 802.IQ v1 Configuration Section
Enabled
This parameter enables ( √ ) or disables the 802.IQ feature. The default value is disabled.
Initial RTT
The parameter Initial RTT (Round-Trip Time) is used to help determine the elapsed time, in milliseconds, between an “access point” transmission and a “terminal” acknowledgement. The access point continuously adjusts the acceptable round trip time, calculating the average elapsed time over a number of transmissions for each terminal. If an acknowledgement takes longer to receive than the average round trip time calculated, the access point will resend the transmission.
Because access point(s) cannot calculate an average round trip time without a number of transmissions, a starting point or “Initial Round Trip Time” is required. The access point uses the time assigned to the “Initial RTT” parameter as a starting value for round trip calculations. Once the access point begins transmitting and receiving data to and from the terminal, this value will be adjusted to reflect the actual average round trip time between transmissions and acknowledgements.
The acceptable value ranges from 10 to 10000. The default value is 1000.

The acceptable value ranges from 1501 to 65535. The default value is 2457.
Important: The Protocol Type ID default value is rarely changed. If the proto-
col type is changed, all terminal devices must be changed to match.
Forward 802.IQ Packets Only
When bridging packets between the wireless and wired systems, this parameter enables the 9150 to automatically filter out and discard all non-802.IQ packets.
The default setting is disabled.
Give Higher Priority To 802.IQ Data
When enabled ( √ ), this feature queues 802.IQ packets ahead of all other packet types (excluding voice packets, if applicable). If the parameter is disabled, 802.IQ packets are not prioritized and are treated like any other packet type.
The default setting is enabled.

Important: The 9150 must be rebooted for changes to this parameter to
take effect.
The range of values is: Auto, Fixed 1, Fixed 2, Auto 2, Fixed 5.5, Auto 5.5, or Fixed 11Mb/s.
The default setting is Auto.
4.2.1.6 Wireless Distribution System (WDS) Configuration
The 9150 Wireless Gateway can be used as an 802.11b wireless access point (AP) to extend coverage area or for locations difficult to wire; or two 9150s can be used as an 802.11b bridge connecting two separate wired networks.
The 9150 access points are linked to each other in the Wireless Distribution System (WDS). To do this, each of the 9150s in the WDS must be configured to identify the other access points in the system, using their MAC addresses as described in the fol­lowing parameter. Examples of various configuration scenarios are provided in Figure 4.2 on page 77 through Figure 4.5 on page 78.
Note: The Basic Service Set (BSS) operates independently of the WDS. How-
ever, the BSS and WDS share the same bandwidth. For information on BSS, please refer to “Basic Service Set (BSS) Configuration” on page 75.

MAC Address Of Remote AP
Each wireless access point linked to this 9150 must be identified by entering its MAC address here, and the connection must also be enabled ( links can be supported. This 9150’s MAC address must also be configured and enabled on each of the other access points linked to it in the Wireless Distribution System.
Important: If there are two radio cards in the wireless 9150 access point, one
radio should be configured for the WDS link, and the other for BSS coverage. If both radio cards are set for the WDS, one will be auto­matically disabled.

4.2.1.7 802.1X Authenticator Configuration
These parameters govern the configuration of the 9150 when it acts as an authenticator in an 802.1X system. 802.1X is an enhancement to 802.11 which provides greater security.
Mobile devices (“supplicants”) request access to the wireless 802.11 network; the 9150, acting as an “authenticator”, passes their requests on to a separate “authentication server”.
If the server approves the authentication request, the 9150 opens a port for the supplicant, and then acts as a bridge, passing packets between the supplicant and the wired network. If the server denies the authentication request, the 9150 discards supplicant packets addressed to the wired network.
Port Control
This parameter specifies how the authenticator handles the port that it assigns to the supplicant. The default value is Auto. If this parameter is set to ForceAuthorized, the 9150 allows any supplicant to connect. If this parameter is set to ForceUnAu- thorized, the 9150 allows no supplicant to connect.

Quiet Period
This parameter specifies the number of seconds during which the 9150 ignores authentication requests on a port, after receiving a message denying connection from the authentication server. Using this delay makes brute force attempts to break security less practical. The default value is 1 second.
TX Period
This parameter specifies the retransmit time for authentication requests from the supplicant during establishment of authentication. The default is 30 seconds.
Supplicant Timeout
After this number of seconds, the 9150 decides that the supplicant is not responding to messages during the authentication process. The default value is 30 seconds.
Server Timeout
When the 9150 does not receive a response from the authentication server after this number of seconds, the 9150 assumes that the authentication server (the RADIUS server) is down or not able to respond. It sends an “authentication failed” message to the supplicant. The default value is 30 seconds.
Max Requests
This is the maximum number of times the 9150 will retransmit an EAP request to a supplicant before it ends the current authentication session. The default value is 2.
Transmit WEP Key
When this parameter is enabled ( √ ), the 9150 relays to the supplicant the “session key” received from the RADIUS server. For this feature to work, the supplicant must be capable of using the TLS authentication method.
Reauthentication Enabled, Reauthentication Period
When the Reauthentication Enabled parameter is checked ( √ ), the 9150 requires connected devices (clients) to reauthenticate themselves after the period of time (in seconds) specified by Reauthentication Period. The default values are disabled and
3600.

4.3 Access Point Configuration Menu Options

The Access Point Configuration main menu consists of four sub-menus:
MAC Bridge Parameters, Mobility Configuration, Mobile IP Parameters, and
802.1X Authenticator Parameters.

4.4 MAC Bridge Parameters

The MAC Bridge parameters consist of protocol filters that direct the 9150 to forward or discard frames that contain a known protocol type. This enables the 9150 to be selective of what types of frames will be bridged over the radio, in order to limit traffic on busy networks. Filtering frames is based on the protocol information in the frame. This is discussed in detail in “Protocol Filters” on page 89.
The MAC Bridge Parameters page is entered from the Access Point Configuration menu on the first page, as shown above.
Figure 4.6 on page 82 charts the pages for the MAC bridge filters. Entering “OK” or “Cancel” in the individual Filter pages will return you to the Bridge Parameters page.

The default value is enabled.
Address Filters Enabled
The checkbox in this parameter enables or disables the Address Filters function. If filtering is enabled ( addresses. The list of MAC addresses for filtering is set by the Address Filters option on page 87. Frames are filtered and either forwarded or discarded, depending on the rest of the settings in this configuration. If filtering is disabled, no filtering will be done based on MAC addresses.
√ ), the 9150 can filter out frames based on destination MAC
Address Filters Default Action
This parameter determines which Address Filters Default Action (discard or for- ward) will be performed when the Address Filters Enabled parameter is checked
(
√). If an address does not match any of the addresses set in the Address Filters
configuration (see page 87), then it will take the Address Filters Default Action selected in this parameter.

General Configuration
For example, the Address Filters Default Action may be to discard all frames des- tined for addresses not matched in the configuration database. Therefore if the address type field is not matched, the frame will be discarded. But if an address type field is matched in the database, the frame will be forwarded for that address.
Conversely, if the default action is to forward all frames destined for addresses not matched in the configuration database, those frames will be passed on for those addresses, but frames for an address type field matched in the database will be discarded.
Protocol Filters Enabled
The checkbox in this parameter enables or disables the Protocol Filters function. If filtering is enabled ( depending on the rest of the settings in this configuration. If filtering is disabled, no filtering will be done based on protocol frames.
√ ), frames are filtered and either forwarded or discarded,
Protocol Default Action
This parameter determines which Protocol Default Action (discard or forward) will be performed when the Protocol Filters Enabled parameter is checked ( Protocol Filter (see page 89) also has a forward/discard action associated with it. If a frame does not match any of the filters set in the Protocol Filters configuration, then it will take the Protocol Default Action selected in this parameter.
√). Each
For example, the Protocol Default Action may be to discard all frames. If a type field is matched in the configuration database, and the Filters action is forward, the frame will be passed on. If the field is not matched, then the frame will be dis­carded. Therefore if you want only IP frames forwarded, after selecting the appro­priate IP Type in the Ethernet II Filters (see page 92) the discard setting here will drop all frames containing other protocol types.
Important: If Protocol Filters Enabled is checked, and the Protocol Default
Action is discard, an HTTP browser will not be able to access the
9150’s configuration pages unless an ARP filter is defined to forward ARP packets. To do this, configure Ethernet II Filters to forward protocol type 0x0806 (ARP) packets (see page 92). Alterna­tively, you can create a static entry in the ARP table on the compu­ter that is running the browser.
