Introduction
Part # 34357-MNL Rev. B SPEEDLAN 9200 User Guide
Features and Benefits
SPEEDLAN 9200 Features
The SPEEDLAN 9200 series introduces the second generation of wireless routers. The SPEEDLAN 9200 offers the following new features:
New Wireless Mode parameters (e.g., 5.8GHz OFDM, 2.4GHz DSSS or 2.4GHz
OFDM, 4.9GHz OFDM, Preamble, Tx power and SSID). For more information, see Configuring the Radio Parameters, page 3-44.
Double the transmission rate with turbo mode, up to 108Mb/s for 5.8GHz
OFDM. For more information, see Configuring the Radio Parameters, page 3-44.
You can allow a mesh node in a 9200 network to communicate with a
SPEEDMesh-enabled client in adhoc mode. For more information, see Enabling/ Disabling the SPEEDMesh-Enabled Client, page 4-6.
Provide network security between SPEEDMesh-enabled clients (PDAs and
laptops) and SPEEDLAN 9200 routers via WEP. In a SPEEDLAN 9200 network, you can authenticate a SPEEDMesh-enabled client with a standard security mechanism called Wired Equivalent Privacy (WEP). WEP encrypts data that is transmitted over the wireless LAN. WEP protects the wireless link between clients and access points. Network administrators can control access via standard 802.11 client using WEP. For more information, see B. Enabling WEP Security Between a SPEEDMesh-Enabled Client and SPEEDLAN 9200, page 4-5.
1-2
RTS/CTS allows you to fine-tune the operation of your wireless LAN. RTS/CTS
will help minimize collisions between transmissions from hidden nodes on the wireless network. For more information, see Request to Send (RTS) / Clear to Send (CTS), page 4-8.
Provide DHCP relay: This release of the SPEEDLAN 9200 shall use the DHCP
relay function to forward DHCP requests from non-SPEEDLAN wireless clients to one or more DHCP servers. Those DHCP servers may be suitably configured SPEEDLAN 9200 routers (in which they won’t relay), or they may be dedicated servers, reachable through the Ethernet interfaces of one or more of the SPEEDLAN 9200 routers. To configure DHCP relay, see Configuring DHCP Relay, page 3-63.
Support for DC input sources: Devices that lack AC power will require DC-to-
DC supply.
SPEEDLAN 9200 User Guide Part # 34357-MNL Rev. B
The SPEEDLAN 9200 offers the network manager unsurpassed flexibility in meeting the
challenges of designing, building and managing to day's wireless broadband networks.
In a mesh topology, the SPEEDLAN 9200 routes traffic around physical limitations, eliminating the line-of-sight (LOS) issue present in star topology-only networks. Each mesh router will communicate with other mesh routers in a radius of up to 2 miles depending upon the model and signaling rate selected. This creates a multi-hop IP routed cell: self-healing, load balancing, and scalable network. By removing LOS issues caused by large buildings, hills, and other obstructions, service providers can reduce network deployment costs while maximizing their broadband wireless investment and reach new markets that could otherwise not be served.
For more information about mesh, see SPEEDLAN 9200 Mesh Protocol -- How It Wo rks in Mesh Cells, page 1-7.
ISP Functionality
The SPEEDLAN 9200 products are tailored to fit the needs of Internet Service Providers and Broadband Telecommunications Providers. Two features particularly useful to Internet Service providers are Network Address Translation (NAT) and Dynamic Host Configuration Protocol (DHCP). NAT helps to ensure network security and allows an entire company to share a single global IP address for communication on the Internet. This enables companies to communicate with other devices on the Internet. DHCP servers provide efficient use of IP addresses by assigning them dynamically or statically to the wireless router location. DHCP allows network administrators to dynamically assign IP addresses for the period of time needed to connect to the Internet or network.
IP Router Functionality
The SPEEDLAN 9200 is a highly configurable wireless IP router which supports mesh topologies. In addition to being configurable via a standard web browser, the SPEEDLAN 9200 also contains a firewall to control incoming and outgoing traffic, preventing unauthorized access.

Part # 34357-MNL Rev. B SPEEDLAN 9200 User Guide
Configuration Management
The SPEEDLAN 9200 Configurator is a web-based management tool that allows a network manager to configure routers. For more information, see General Functions of the Configurator, page 3-1.
SPEEDManage
The SPEEDManage suite offers network management tools to help you troubleshoot and resolve network issues to keep your network running. Packaged in SPEEDManage are SPEEDView

routers.
You can recover lost IP addresses. (Use IP Recover in SPEEDManage.)
Bandwidth Limiting: Users will now have the ability to control the bandwidth use
of each SpeedLAN unit in a mesh or a star network. This feature allows control­ling the amount of traffic from the Wireless Port to the Ethernet Port and also from the Ethernet Port to the Wireless Port with independent parameters.
ToS [Type of Service]: ToS provides a comprehensive traffic classification
scheme and the choice of 8 levels of priority selection for each classification. Tagged traffic is classified by its DiffServ Code Point, and untagged traffic by other set of properties like for example the protocol and IP port.
License Control: Allows a Speed LAN unit to be licensed to communicate with a
certain number of mobile clients that associate to it. The license if provided by uploading to a given unit a license file specific for that unit. This is a feature once believed by marketing to be a potential source of revenue. [A mobile client is a laptop or PDA with a standard radio card that and on which our mobile client application has been installed]
Configuration File Upload/Download: This feature was added at the request of
several customers since it helps the operations, administration and maintenance of a network because it simplifies the process of unit configuration that generally requir es a good degree of expertise and can lead to errors.
System Log: A configurable Sys Log capability was added to improve trouble-
shooting and general network management.
Ethernet Port DHCP Client: The DHCP client has been enhanced. The new
design propagates and uses additional fields provided by the DHCP server in the network.
Wireless Port DCHP Server: Server support has been added to the Wi reless Port
to assign IP addresses to mobile mesh clients.
Note: Advanced Encryption Standard was adopted by the National Institute of Standards and Technology in October of 2000. AES presents a new level in computer networking security, especially important in wireless communications because wireless circuits are easier to tap than their hard-wired counterparts.
AES is more difficult to crack than its predecessor Data Encryption Standard. These routers use an AES 128-bit encryption key.
Encryption Note! A Web browser must support 128 bit encryption in order to be used with the Configurator. For more information about AES, visit http://www.nist.gov. This User

Priority Queuing
Despite having two physical interfaces, a SPEEDLAN 9200 router can experience congestion. That is because the interfaces' bit rates are not matched. Specifically , packets can ingress (enter) the Ethernet interface faster than they can egress (exit) the wireless interface. If this occurs briefly, it is called short-term congestion, which can cause increased packet delay and/or jitter. If congestion lasts too long, it can cause packet discard ("loss"). Long-term congestion in a SPEEDLAN 9200 will typically only occur when it receives excessive unthrottled UDP traffic at its Ethernet interface. TCP traffic will self-throttle, typically experiencing only short-term congestion, if any.
A SPEEDLAN 9200 mitigates short-term congestion by providing priority egress queuing at its wireless interfaces. With priority queuing, packets may be transmitted in a different order than they wer e received. This allows favoring network management, VoIP and SCADA, over SMTP, ftp, and NNTP (for example).
1-6
How does Priority Queuing work? The packets are prioritized into a hierarchy of queues, based on class of traffic. The highest priority queue packets are serviced first. When the highest queue is emptied, the next lower queue is serviced. The SPEEDLAN 9200 has four levels of priority queues. Queue 1 (the highest queue serviced) contains "management" traffic (i.e., RIP, Mesh& SNMP). Queue 2, the next lower queue serviced, contains "real-time" traffic (i.e., VOIP, Video, SCADA). Queue 3, the next lower queue serviced, contains "non-real time interactive" traffic (i.e., HTTP, SSH and Telnet). Queue 4 (the lowest level queue serviced) contains all traffic that doesn't fit into one of the first three queues. There are no matching or requirements for this queue; it is simply the default queue if the packet doesn't qualify for one of the first three queues.
SNMP
The SPEEDLAN 9200 contains a Simple Network Management Protocol (SNMP) Agent that provides a r emote Network Management System (NMS) with read-only ("get") access to certain configuration and status parameters. For more information, see SNMP, see SNMP, page 3-26.

SPEEDLAN 9200 Mesh Protocol -- How It Works in Mesh Cells
Figure 1-1: SPEEDView illustrating a mesh network (in SPEEDManage suite)
SPEEDLAN 9200 routers provide the unique ability to "self-heal" the wir eless network as the topography changes over time, thereby increas ing the overall stability and performance of the network while allowing traffic to reach buildings blocked by obstructions of line-of-sight.
What is happening in Figure 1-1 on page 1-7?
You will notice negative numbers next to the routers, or referred to as nodes on
the network diagram. These numbers represent the receive signal strength (expressed as dBm) for the links in the network diagram.
The black dots in a mesh network diagram indicate a trace route, which maps out
the current data flow between the selected pair of nodes. A user would select the trace feature to view the data flow between a node pair (for mesh networks only).
This illustration also shows that every router in the mesh cell can be heard by
1-7
Part # 34357-MNL Rev. B SPEEDLAN 9200 User Guide
every other router in the cell, except for the blocked link indicating that there is no signal between those two nodes.
SPEEDView allows you to block traffic over any link in the cell. When you block a connection, the node pair will not be able to communicate. The advantage of blocking a connection is verifying that the path can be re-routed for successful connectivity. (This is done using the "Block" feature in SPEEDView. The broken [or disconnected] link will appear as a red line. This link also appears when there is no signal between two nodes.)
SPEEDView can also be used to perform bandwidth, link and ping tests.

Explaining this scenario on the simplest level (using the Mesh protocol as shown in Figure 1-2 on page 1-8). A can route a packet to B, despite the tree obstruction (block of trees) within the path. How does this procedure work?
D
1 A has line-of-sight to C but not to B. 2 C has line-of-sight to A and to B.
The most efficient path in this case is to hop from A to C to B. Note: No manual programming is required because A automatically detects its
neighboring router (in this case C, and B and detect a clear path to C). Therefore, the packet is successfully routed around the obstacle between B and A.
This process creates a more scalable, flexible, and extended wireless network (as shown in Document Changes & Corrections/Firmware Updates, page 1-11).

SPEEDLAN’s Mesh Cell Architecture
Specifically designed to meet the connectivity demands for everyone from single users to large corporations, all SPEEDLAN 9200 models are equipped for mesh operation. These models will communicate with every other mesh router within an unobstructed path.
Figure 1-3: An examp le of a mesh network
SPEEDLAN 9200 Mesh Core Components
SPEEDLAN 9200 Mesh protocol includes three central components which are neighbor discovery, topology updates, and routing.
Neighbor Discovery
Neighbor discovery occurs when each router sends a broadcast "hello" message to detect those routers to which it has line-of-sight. The "hello" sender acknowledges those replies, whereupon the sender and the neighboring router add each other to their r espective active neighbor lists. Neighbor discovery protocol messages are sent by each router on startup and periodically thereafter. The periodic messages are required to determine when a former neighbor can no longer be reached, whereupon it is removed from the active neighbor list. Neighbor discovery messages are relatively short and are sent infrequently enough that they don't constitute significant overhead.
Topology Updates
When a router adds or deletes a neighbor to or from its active neighbor list, it propagates that information to the rest of the routers in the wireless mesh LAN. Unlike classic wired routing protocols, topology update notifications are not flooded. Instead they are sent via a spanning tree, such that each router receives only one notification of a particular event. (A brief explanation of the spanning tree algorithm is explained in the note below.) This approach also conserves bandwidth for use in forwarding user traffic. Since each router
1-9
Part # 34357-MNL Rev. B SPEEDLAN 9200 User Guide
knows the topology of the entire wireless LAN, it can determine the shortest path to each peer router in the wireless LAN.
Note: In short, the spanning tree algorithm enables units to dynamically locate a subset of the topology that is loop-free. The spanning tree algorithm determines the best path a unit can use to send a message.
Routing
Routing is simply the act of forwarding a received Internet Protocol (IP) datagram (a block of data) toward its destination. The router compares the destination IP address to entries in its routing table. If the destination is a wireless neighbor or a node connected to the router's wired LAN, the router sends the datagram directly to the destination. Otherwise, it sends the datagram to another router, which must be on the wired LAN or be a wireless neighbor.
In wired broadcast LANs, all routers on the LAN can hear each other. Therefore, a datagram only passes through a router when it is moving from one LAN to another LAN along the path to its destination. In a mesh wireless LAN, not all routers can hear each other. Therefore, a router within a wireless LAN may forward a datagram to a neighbor router within the same wireless LAN, in or der to send the datagram towar d its destination. For each datagram, the routing algorithm minimizes the number of router-to-router hops within the wireless LAN, thereby also conserving bandwidth for other user traffic.
1-10
Why SPEEDLAN Outperforms Other Routing Equipment
The SPEEDLAN 9200 outperforms other routers because the SPEEDLAN 9200 routing table broadcasts only the information that changed, such as when new routes ar e added or old routes are removed from the network. This information is sent to the router's immediate neighbors along the most efficient path to the end destination. This process helps conserve bandwidth. If an existing path is modified in some way, by the addition or deletion of a router, a SPEEDLAN 9200 using the Mesh protocol can monitor its routing table to decide if a secondary path should be taken. One could call this a "self-healing" network, which means it finds a secondary route through the network without manually reprogramming the routers.

point-to-multipoint link. It can be used with a 2.4GHz or 5.8GHz external antenna.
SPEEDLAN 9204: This model provides the same functionality as a SPEEDLAN
9201, but it uses an integrated 5 dBi omni (for 2.4GHz only). The SPEEDLAN 9204 is intended for more densely populated cells.
SPEEDLAN 9200 (Option #10-15): This is the new model numbering format.
The Option # identifies the router’s topology capabilities. See the following Table 2-1.
Table 2-1: 9200 Topology Configuration Table
As of October 2005, the model numbering format changed. The new model numbering format uses a Configuration Option # to distinguish different models.
The SPEEDLAN 9200 is housed in a waterproof, cast enclosure that mounts outside the building, on a mast, or tower. The SPEEDLAN 9200 allows up to 300’ of specialized, outdoor Ethernet cable to be used between the LAN and the RF device, without loss of any radio signal. This increases the effective wireless link distance and reduces or even eliminates the need for an amplifier.

To install your SPEEDLAN 9201/SPEEDLAN 9204, follow the steps below: Step 1: Mounting the SPEEDLAN 9201/SPEEDLAN 9204 This router will have an omni directly attached. No additional steps are needed for this
step. Go to Step 2. Step 2: Mounting the SPEEDLAN 9201/SPEEDLAN 9204 on the Pole
Pole Mount: Attach the router to the mounting pole using the two V-bolted
clamps and aluminum bracket, one on top of the router and the other on the bot­tom of the router. Make sure you tighten the nuts for the clamps securely to pre­vent shifting of the router after antenna alignment.
Step 3: Running the Cabling
1 Run outdoor CAT5 cable (from bottom of router) down to junction box located
inside the building.
2 Secure grounding wire by running this wire to a suitable "earth" ground and fas-
ten it securely in place. See the installation diagram following these directions.
3 Install proper indoor ground plug into the junction box. Connect the outdoor
CAT5 Ethernet to the "radio" jack. Connect the LAN Ethernet cable to the "LAN" jack of the junction box. Install the power supply DC connector to the junction box. Plug the external power supply into the wall outlet. (The VAC power outlet’s input voltage of this universal adapter can vary from 100 to 250 VAC.) Connect the DC output of the adapter to DC jack on the indoor junction box.

4 Connect the wireless SPEEDLAN 9201/SPEEDLAN 9204 to the customer's
Ethernet LAN or PC by connecting the RJ-45 plug on a standard Ethernet CAT5 cable to the RJ-45 port connector, marked as "LAN" on indoor junction box. Connect the other end of the Ethernet CAT5 cable to your Ethernet hub, switch or router.
Important Note: Waterproofing the External Connectors!
Make sure you waterproof all the connectors, as follows: Apply two layers of electrical tape to the connector (covering three inches of cable past the connector), and leave approximately 3 inches of cable exposed on either side of the connector. An alternative is to begin at the lowest point, so the tape overlaps from bottom to top creating a shingled effect. (This creates an effective barrier against runoff.) Apply this "shingle effect" to each layer of the sealing process. Then, apply one layer of insulation putty over the top of the electrical tape, and leave at least one inch of the cable jacket to ensure a good seal. Do not stretch the putty, as this causes thinning and reduces the effectiveness of a good seal. Finally, apply five layers of electrical tape over the insulation putty and extend at least one (1) inch past the putty. This is the most important step in a creating a watertight seal. Make sure that there are no wrinkles in the tape, and the final wrap must be completed from bottom to top.

To install your router with an external antenna, do the following:
Step 1.Verifying Line-of-Sight
Before installing the antenna and router, make sure a clear line-of-sight exists between the two points. Line-of-sight can be defined as each antenna clearly seeing the other antenna, and seeing the remote locations when viewing from the central base location. Be sure to look at the center of origin of the transmission (i.e., the middle of the antenna). Repeat this procedur e from the remote location. Any disruption of the signal path due to trees, building, or any other obstructions may cause the link to function incorrectly. Make sure at least 60 percent of the RF signal is unobstructed by any path blockages.
Visual Line of
Fresnel Zone
Tower
bove
Obstruction
bove Mean Sea
Earth
Figure 2-7: Line-of-sight (LOS) diagram
Note: For long distances, additional antenna height is often required to overcome signal diffraction and to provide clear Radio LOS. For Radio LOS, a clear Fresnel (Freh-nel) zone is required to minimize diffraction effects. The Fresnel zone is shaped like an elongated football. The most clearance is required at the mid-point between the two sites.
Beyond approximately 10 miles, the curvature of the earth can also become significant. At these longer distances, visually sighting the remote site can be difficult or impossible due to atmospheric haze. Terrain data (map or differential GPS) must be relied upon for determining path clearance. Elevation data determined with these methods is above Mean Sea Level; and does not account for curvature of the earth. Both the curvatur e of the earth and the Fresnel clearance numbers can be combined to determine the additional clearance required above any natural or man-made obstructions along the path.
2-15
Part # 34357-MNL Rev. B SPEEDLAN 9200 User Guide
Obtaining this clearance can be accomplished by raising the antenna height at one or both sites. If this is not practical, then consider relocating one or both sites to locations with higher elevations. Another option is to add a third site to go over or around the obstacle.
If you see any obstructions between two antennas, move one or both antennas to another location.
Step 2. Mounting the Antenna
Follow the instructions below to mount the antenna.
a On a side-building mount, position the bracket so there will be at least three feet
(one meter) above the roof line where the pole is attached. This enables room for the antenna and reduces signal loss from building reflection.
Note: It is not recommended to mount the antenna onto any unstable object.
b Allow for as much space between the wall brackets as possible while
maintaining the appropriate antenna height. For extended poles, additional wall brackets may be necessary.
c Assemble the antenna and mount it to the pole using the included V-bolt antenna
mounting hardware. For a semi-parabolic grid type antenna, align the grid to run parallel with the grid on the tip of the antenna horn. A horizontal grid should be horizontal (or parallel to the ground). A vertical grid should be perpendicular to the ground. Make sure all bolts and screws are fas­tened tightly.

d Fasten the pole to the brackets. Position the antenna, point it in the
appropriate direction, and tighten the screws. Then, aim the antenna so it is pointed toward the receiving antenna on the other building. The radio signal radiates from the end of antenna like a wide-beamed flashlight. For optimal per­formance, you may need to test your link using both horizontal and vertical-oriented polarities. This configuration option varies with each location, as well as RF signals that may be present in the area.
Step 3. Mounting the SPEEDLAN Router
Select one of two options below:
Option A: Pole Mount
On a pole mount, position the router 5 to 10 feet below the antenna. Then, attach the router to the mounting pole using two included V-bolt clamps, one on the top of the router and the other on the bottom. Make sure you tighten the nuts for the clamps on the back of the pole mount.
OR
2-17
Part # 34357-MNL Rev. B SPEEDLAN 9200 User Guide
Option B: Wall or Concrete Mount
On a side building mount, position the router 5 to 10 feet below the antenna. Then, attach the SPEEDLAN router to the wall or concrete by using the concrete or wood mounting screws. Make sure it is securely mounted on the wall.
Step 4. Running and Securing All Cable
The installation kit includes two cables with ready-made connectors to fit your particular installation needs such as:
3’ RF cable
10' antenna cable (attaches to antenna one end and to lightning arrestor other
end)
Lightning arrestor (attaches to pigtail and to antenna cable)
a Attach the 3’ RF cable to the RF port on the router. b Attach the 10' length of cable to the antenna. Next, attach the lightning
arrestor to the lower end of the antenna cable.
c Attach the other end of lightning arrestor to 3’ RF cable. d Run the main length of the specialized outdoor Ethernet cable from the router to
the indoor junction box located inside the building.
e Secure the cable (i.e., to the pole) with zip ties or cable clamps during this
procedure.
2-18
SPEEDLAN 9200 User Guide Part # 34357-MNL Rev. B
f Don’t forget: If your installation requires the use of an RF Filter because you
plan to transmit at 5.8 GHz using an antenna whose gain is greater than +17dBi as mentioned in the note at the bottom of page 2-11, then you will install the RF filter between the RF output of the router and the RF input of the antenna.
2-19
Part # 34357-MNL Rev. B SPEEDLAN 9200 User Guide
Note: When running the cable through walls or obstructions, make sure that there is ample room for the connector to pass through the opening without being damaged. Also, do not create extra pr essur e that would cause the cable to kink or be stretched or cut (i.e., pulling cable through tight locations).
g Create a proper weatherproofing seal on all outdoor connections by wrapping it
with electrical tape and sealing it with putty. This is the most crucial step of the installation. If this procedure is not completed, long-term and complex problems could occur. For more information on implementing this procedure, see Weather­proofing Connectors, page 2-19.
h Next, ground the lightning arrestor. For more information, see Grounding the
Lightning Arrestor, page 2-19. Y ou can also gr ound the router case to the ground, as shown in the installation diagrams in this chapter.
Step 5. Grounding the Lightning Arrestor
a Mount the lightning arrestor to a solid surface. b Run the grounding wire from the lightning arrestor to a proper ground source
such as a grounding rod or roof ground wire. The lightning arrestor is NOT waterproof. The next series of steps will show you how to effectively seal the lightning arrestor and its cables.
Step 6. Weatherproofing Connectors
a Seal the entire lightning arrestor with the black waterproof sealant insulation
putty that is included in the installation kit.
b Apply two layers of electrical tape to the connector, and leave approximately 3
inches of cable exposed on either side of the connector. An alternative is to begin at the lowest point, so the tape overlaps from the bottom, below the bottom connector over the lightning arrestor and beyond the upper connector, to top creating a shingled effect. (This creates an effective barrier against water runoff). Apply this "shingle effect" to each layer of the sealing process.
c Apply one layer of insulation putty over the top of the electrical tape, and leave at
least one inch of the cable jacket to ensure a good seal. Do not stretch the putty, as this causes thinning and reduces the effectiveness of a good seal.
2-20
SPEEDLAN 9200 User Guide Part # 34357-MNL Rev. B
d Apply five layers of electrical tape over the insulation putty and extend at least
one (1) inch past the putty. This is the most important step in creating a watertight seal. Make sure that there are no wrinkles in the tape and the final wrap must be completed from bottom to top.
Step 7. Connect the Router to Customer's Ethernet LAN
a Connect the RJ-45 connector on a standard Ethernet CAT5 cable to the "LAN"
RJ-45 port on the indoor junction box.
b Connect the other end of the Ethernet CAT5 cable to your Ethernet hub, switch or
router.
Step 8. Connect the Wireless Router to the Power Supply
a Connect the DC output of the adapter (24-36 Vdc) to DC jack on the indoor
junction box.
b Connect power cord of AC-DC 24-36 Vdc adapter to 110 or 220 VAC power
outlet (the input voltage of this universal adapter can vary from 100 to 250 V AC).
Step 9. Adding Additional Routers

Manual Initial Configuration of the SPEEDLAN 9200
Each SPEEDLAN 9200 is produced with a default configuration that renders it usable in many applications. However, if you need to manually configure your SPEEDLAN 9200
router, follow the directions below.
Prerequisites
Configuration of the SPEEDLAN 9200 is done through the SPEEDLAN 9200 Configurator. In order to access the SPEEDLAN 9200 Configurator, you must have:
a client workstation (e.g., PC, Mac, Sun),
a compatible browser (Netscape Navigator 4+ or Internet Explorer 5+), and
3-2
SPEEDLAN 9200 User Guide Part # 34357-MNL Rev. B
a TCP/IP connection to the SPEEDLAN 9200.
A TCP/IP connection to the SPEEDLAN 9200 can be made through its wireless interface or through its wired interface. If the default configuration creates a wireless LAN that is
compatible with the target inter-network, the network administrator can connect to the individual SPEEDLAN 9200 router through that wireless LAN.
The following section assumes that a SPEEDLAN 9200 router is being configured via its wired interface, possibly before it is installed at its intended physical location.
Connecting a SPEEDLAN 9200 and a Client PC
A connection between a SPEEDLAN 9200 and a client PC may be established using either:
1
one crossover cable, or
2 two straight-through cables (also called patch cables) and a hub or a switch.
If you select option # 1, connect one end of the crossover cable to the client PC
and the other end to the junction box.

Figure 3-2: Crossover cable and pin out diagram
Note: The crossover cable actually crosses the transmit and receive pairs of wires so that direct communications can take place between devices. Use a crossover cable anytime you need to interconnect two computers or two devices in the same location when a hub or a switch is either unavailable or not practical.
If you select option # 2, connect a straight-through cable from both the client PC
and the junction box to the hub or a switch.

SpeedLan 9200 comes from the factory pre-configuredwith a private IP network address
192.168.69.1 and a ?24 netmask (255.255.255.0)
Follow these general directions to configure your Speedlan connection:
Open the Control Panel, and then double-click the Network and Dial-up Connec-
tions icon. Go to TCP/IP Protocol Properties to verify that your PC is on the same
network as the router 192.168.69.x (x is in the range of 2 - 254), and the subnet mask should be /24 (255.255.255.0). If you made changes, accept the changes and close this dialog box. Then, restart your computer.
Before continuing you should verify that the client PC has TCP/IP connectivity with the SPEEDLAN 9200. The most common way to do this is to run 'ping' 192.168.69.1
3-4
SPEEDLAN 9200 User Guide Part # 34357-MNL Rev. B
(or the DHCP assigned address) at a command-line prompt. This ping command is available in a Windows 9x DOS prompt, a Windows 2000 / NT / XP command prompt, or any Unix console.
Configuring the SPEEDLAN 9200
Once your PC can access the SPEEDLAN 9200, you can open the client's browser and enter the IP address of the SPEEDLAN 9200 router.
Note: SPEEDView gives you a "monitoring" view of the network. You will use the SPEEDLAN 9200 Configurator (web browser) to configure the SPEEDLAN 9200 routers.
If you want to configure a router in SPEEDView, just double-click any router and it will open the SPEEDLAN 9200 Configurator. For more information about SPEEDView, see
the SPEEDManage User Guide.
Wireless Interface IP Address Assignment
If the wireless interface does not already have a statically configured IP address, it will assume the 10.x.y.z/8 address, where x, y, and z are the decimal representations of the
least significant three octets of the IEEE 802 MAC address of the SPEEDLAN 9200’s wireless interface. This method is used to ensure uniqueness. Because the last thr ee octets
of the IP address are variable, a /8 netmask (255.0.0.0) is used in order for the SPEEDLAN 9200s to communicate on this network.
Automating the Configuration of Multiple SPEEDLAN 9200s
Some of the configuration parameters for the SPEEDLAN 9200 are common to all SPEEDLAN 9200s in the same network, for instance the channel and signaling rate of the
wireless interface.
Completing Configuration
Certain configuration parameters require a reboot after they have been changed. Therefore, to ensure all changes have been activated, each SPEEDLAN 9200 should be
rebooted when its configuration is complete. Multiple SPEEDLAN 9200 routers can be rebooted at the same time from either the SPEEDView application or the SPEEDLAN
3-5
Part # 34357-MNL Rev. B SPEEDLAN 9200 User Guide
9200 Configurator. To reboot the router in the SPEEDLAN 9200 Configurator, choose Reboot from the System menu (see Reboot, page 3-30).
Adding Additional SPEEDLAN 9200s to the Wired Network
If you need to add an additional SPEEDLAN 9200 to the wired network, do the following:
Connect the additional SPEEDLAN 9200 routers to a hub or switch on the
network and have DHCP assign IP addresses dynamically.
Connect additional SPEEDLAN 9200 routers to a hub or switch on the network
one at a time, changing the wired IP address of each router as it is added, to an address other than 192.168.69.1 (to avoid duplicate IP addresses). If you need help, contact your system administrator.
Overview of the SPEEDLAN 9200 Configurator General Main Menu
How the Configurator Menu is Structured
Base stations, CPE routers, point-to-point routers and mesh routers all use the same main menu, as shown in Figure 3-4 on page 3-9. However, some of the submenus are limited depending on which mode you are operating, such as base station mode, CPE mode,
point-to-point (primary and secondary), and mesh mode.
Any configuration that is common for the base station, CPE, point-to-point, and mesh router is located in this chapter.
Network menu
Use this menu to view a list of the interfaces that exist on the router, such as wireless interfaces, fixed interfaces, or both. This is where you would assign either a static or dynamic Internet address for the router. You will also be able to define the display name for the wireless or fixed device and add an Alias IP. For mor e information, see IP Address Configuration, page 3-18.

address to the interface. For example: you may want to assign a "static" (perma­nent) address to a computer that will always be used as a server. This enables other computers to connect to it. Static addressing is also beneficial to users that need to maintain a "constant" connection to the Internet. Then, click Apply.
Note: If you selected the "Use this static address" option, enter the Internet address that you want to assign to the interface in the IP Address text box. You will also enter the subnet/netmask for the IP address. Select the appropriate netmask in the Netmask drop­down list.
After you change the Internet address for an Ethernet or directly connected interface, you must restart the interface. Otherwise, the information will not be activated. If you follow this step correctly, the next time you open the SPEEDLAN 9200 Configurator, these changes will be updated.
Alias IP
Note: Alias IP addresses can only be created for the Ethernet interface. They are not for the wireless interface.
To add an Alias IP, do the following:
3-21
Part # 34357-MNL Rev. B SPEEDLAN 9200 User Guide
1 Choose IP Addresses + Ethernet from the Network menu. Next, click the Addi-
tional IP Addresses button on the IP Address Configuration (Ethernet) page. The
IP Addresses Configuration (for Ethernet) page will appear:
Figure 3-16: Adding an Additional IP Address (Alias IP)
2 Aliased addresses cannot be dynamically assigned from the DHCP server, so you
must manually type in the Alias IP in the text box, circled above. Verify the netmask and click Add. Repeat this step for each Alias IP you add to the Ethernet interface.
3-22
Other elements on this window are described below:
# - (Address Number): The first address is the primary IP address on the
Ethernet interface. Addresses numbered 2 or higher are aliases.
IP Address: Lists the IP address of the primary or alias address.
Netmask: Lists the netmask of the primary or aliased address.
Network: Lists the network number of the primary or aliased address.
Broadcast: Lists the broadcast address of the primary or aliased address.
Virtual Addresses
Choose Virtual Addresses from the IP Addresses submenu (under the Network menu) to create a public IP address that can be mapped to a private IP address. Virtual addresses
are IP addresses (usually public) that the SPEEDLAN 9200 router can use in addition to the IP addresses assigned to each of its network interfaces. Virtual addresses are
normally used to preserve public IP addresses when a limited number is available. Previously, virtual addresses were implicitly created when referenced in a NAT rule.
SPEEDLAN 9200 User Guide Part # 34357-MNL Rev. B
Virtual addresses can be used to access the SPEEDLAN 9200 router for configuration, or in NAT functions like Address Sharing, Internal Servers, and 1:1 NAT. Virtual addresses are particularly useful when using 1:1 NAT, where you need more than one public IP address. The virtual addresses do not need to belong to a network assigned to one of the
SPEEDLAN 9200's interfaces.
The existence of these addresses will be advertised with RIP, providing that the RIP filters allow it. The Virtual Address page will appear when you choose the Virtual Addresses feature.
The elements on this page are explained below:
IP Address: In this text box, enter the virtual address you want to add. Click Add
to add the new virtual address. (In the next figure, the user entered "13.13.13.16" in the IP Address text box. Next, the user will click Add.)
Notes: You cannot apply an IP address from the Ethernet port’s subnet. All virtual addresses have a netmask of /32 (255.255.255.255).
Existing Virtual Addresses
This list contains all defined virtual addresses.
To remove a virtual address, select it and click Delete Selected. (In the next fig-
ure, if the user wants to remove virtual address "13.13.13.14". Then, the user would select the check box next to it and click Delete Selected.)
To select all addresses, click All. To clear all selections, click None.
If an entry has "(In Use)" instead of a check box (as shown in the next figure to the right of virtual address "13.13.13.13"), this means the virtual address is "in use" and cannot be removed.

The combination of severity and flag defines the logs that user would like to have.
For example if the user has selected WARNING severity and "At or above" flag, then all logs with one of EMERG, ALERT, CRIT, ERR and WARNING severity will be written to the log.
LOG LOCATION
When logging is enabled, log messages are sent to a logging process, which logs messages to designated locations. You can specify to send log messages to local file or to remote server choosing "Local file" or "Syslog server on" respectively.
The local system log file is located in /var/log/ directory which is a symbolic link to /tmp directory. This directory is cleared out at boot or at shutdown by the local system.
LOG ROTATION
Managing of the maximum size of log file is provided by Linux standard daemon called "logrotate". The "logrotate" checks the size of the log file once in hour and if the size is exceeded the maximum allowed size (for now the limit is 100K) then the log file is cleared out and old file is kept in /var/log folder. The maximum number of copies is 5.
MESSAGE STRUCTURE
The message format always follows the same basic pattern. The date and timestamp come first, followed by the computer name -hostname in our example, and then the message itself. The message starts with the name of the program from which it originated, typically followed by the process number in square brackets.

What is RIP-2 MD5 Authentication?
Both RIP-1 and RIP-2 are vulnerable to hostile messages and attacks. This is because broadcast (RIPv1) or multicast (RIPv2) packets alone lack authentication. When RIP-2 is used with an authentication algorithm, such as MD5, network security is increased since the destination receiving the RIP packet knows that it was generated by a reliable source (i.e., the actual sender of the packet).
RIP-2 MD5 authentication transmits the output of the authentication algorithm rather than the RIP-2 authentication key. Therefore, the RIP-2 authentication key is never transmitted over the network and cannot be heard by other routers. This means a router can determine exactly who sent the message and not assume which router sent it.

Each statistic is defined below:
Destination: This is the destination network or host.
Netmask: The netmask is a 4-byte number that masks the network part of the
Internet IP address, so only the host computer part of the address remains.
Gateway: This is a network point that acts as the "entrance door" to another net-
work. This is the first router that takes you to the designated host (i.e., the next hop on the network).
Metric: Metric is a number indicating the preference of one route link over
another. A route link with a lower number will be chosen over one with a higher number.
Interface: This specifies which network interface the route will use.
Source: This lists the how the information is routed to/from the router (e.g., RIP
enabled, static or connected route).

The signaling rate is intended to control the transmit rate, depending on the quality of the link. If the link is getting better/worse, the signaling rate is auto­matically increased/decreased by one increment. By default, all the supported signaling rates for the appropriate protocol are selected. An alternative is to select a subset of the supported rates.

Max Tx Retries and Signaling Rate Fallback
This page includes two features: Max Tx Retries and Signaling Rate Fallback. On the figure below, Max Tx Retries is circled in red and Signaling Rate Fallback is circled in
blue.
Figure 3-33: Tx Retries and Signaling Rate Fallback page
Note: To apply settings to other remote network nodes, select them and click Apply to Selected Nodes. If you want to select all of the routers, click Select All.
The default for Max Tx Retries is 6.
3-46
Signaling Rate Fallback
During the retransmission of a unicast frame, the signaling rate can "fall back" in order to increase the chance of reception. Signaling Rate Fallback can occur multiple times for a single frame. Signaling Rate Fallback occurs from the current rate and will only include those signaling rates selected on the Channel and Rates page. After ten consecutive successful unicast frames, the current rate is restored to the highest selected rate.
The Signaling Rate Fallback parameter allows you to control when the signaling rate will drop, depending on the check box(es) you selected. That is, the check box(es) labeled, "Allow signaling rate fallback on retry" (circled in blue on previous figure).
The following parameters (check boxes) govern at which point in the re-transmission process the rate may be dropped:
1st retry: Will drop signaling rate on first retry.
2nd retry: Will drop signaling rate on second retry.
SPEEDLAN 9200 User Guide Part # 34357-MNL Rev. B
3rd retry: Will drop signaling rate on third retry.
4th retry: Will drop signaling rate on forth retry.
5th retry: Will drop signaling rate on fifth retry.
6th retry: Will drop signaling rate on sixth retry.
7th retry: Will drop signaling rate on seventh retry.
Here is one example.....
2.4GHz DSSS Example:
The network administrator has configured the allowable transmit signaling rates to be 11,
5.5, 2, and 1 Mb/s. (These values can be selected on the Channel and Rates page under the Wireless menu.) In addition, the network administrator has selected 7 from the Max Tx Retries drop-down list and set the signaling rate to "fall back" on the second, fourth, and sixth retry attempts (as shown in blue on previous figure). When the intended recipient does not acknowledge a transmitted unicast frame, it will be retransmitted again (after a short timeout) at the current rate (e.g., 11 Mb/s). If this attempt is also unsuccessful (e.g., the receiver did not acknowledge it), the signaling rate will drop to 5.5 Mb/s and another attempt will be made. If after the third retry, the transmission is still not successful, the signaling rate will drop to 2 Mb/s for the fourth and fifth retry, and then to 1 Mb/s for the sixth and seventh retry (if needed).
The recipient sends acknowledgements at the same signaling rate at which it receives frames. When a frame is successfully transmitted (acknowledgement received in the case of unicast), the transmitter immediately proceeds to the next frame. The last signaling rate used to transmit (other than acknowledgements) becomes the current rate. After ten consecutive unicast frames, the current rate r eturn s to the highest rate selected, if it is not already at that signaling rate. Note that the receiver's signaling rate is not affected (other than returning the acknowledgement at a possibly different rate). Each transmitter's fallback schedule is independent of the signaling rate used by other tran smitters.
Max Tx Retries
P-Com recommends that you use this parameter to increase the throughput of your wireless network. This parameter tells a network node the maximum number of times a unicast frame can be retransmitted before it is disca rded. (A unicast frame is one that is transmitted to a single node in a network.) This allows a network manager to tune a network for its particular topology and expected traffic characteristics. The network

topology, RF environment, number of nodes, throughput requirements, latency requirements, and type of applications ar e all factors in choosing an appropriate value for this parameter.
This parameter can be tuned on a per unit basis in order to optimize network performance. Click Default to get the default value of 7. You can select a value between 0 and 8 from the Max Tx Retries drop-down list.
Max Throughput (Regulating Bandwidth)
Max Throughput is useful to ISPs that want to regulate the maximum wireless bandwidth provided from each customer.
(Range: 100 - 64800)

Figure 3-34: Max Throughput page
The Max Transmit Data Rate (in Kb/s) defaults are 29300 Kb/s for 2.4GHz & 5.8GHz OFDM modes, and 6500 Kb/s for DSSS. The range is from 100 to 64,800 Kb/s (6.5 Mb/s).

ToS
3-50
When ToS is enabled, SPEEDLAN9200 prioritizes the packets based on the DSCP (DiffServ Code Point) in the IP header of the packet to be transmitted to the wireless port. The source of the packet can be Ether net port, Wir eless port, and CPU. 8 priority queues are created to map the user traffic to one of the priority queues based on the configured policies.
When ToS is disabled, one queue is allocated for all the user traffic (non-managem ent). The global maximum throughput applies to this queue. Global maximum throughput is configurable if the "Bandwidth Limiting" feature is enabled.
ToS Configuration
ToS is performed via Forwarding->ToS->Configuration submenu.
SPEEDLAN 9200 User Guide Part # 34357-MNL Rev. B
User can prioritize traffic according to DiffServ Code Points and Service types. Each line will show the current mappings of DiffServ Code Points and Services to corresponding priorities.
To perform the DiffServ Code Point mapping to corresponding priority, "DiffServ Tagged" link is selected. This link opens the new page for DiffServ Code Points mapping (see DiffServ Code Point mapping chapter).
To perform the Service type mapping to corresponding priority, "Untagged" link is selected. This link opens new page for Service mapping (see Service Mapping chapter).

Figure 3-37: DiffServ Code Point Mapping
This page allows user to configure the mapping of the predefined DiffServ Code Points (DSCP) to corresponding priority from range 1 to 8 (8 is the highest priority and 1 is the lowest priority.). 0 priority has a special meaning, which is used for un-mapping given DiffServ Code Point.
SPEEDLAN 9200 User Guide Part # 34357-MNL Rev. B
The "Default" button is used to specify the default mapping for all the Codepoints. By default all DiffServ Code Points are un-mapped except the EF Code Point. The EF Code Point is mapped to priority 8(the highest).
Link ToS Configuration Page is used to return to the previous page (ToS Configuration Page).
Rules for Class Selector Codepoints group
A Class Selector Codepoint with a larger numerical value should be mapped to the higher priority than the Class Selector Codepoint with a smaller numerical value. Entire Class Selector Codepoints group can be map into a minimum of 2 priorities.
Rules for AF Codepoints group
The mapping of each of four AF classes is performed by the following rules: Within each AF class three corresponding AF subclasses are mapped implicitly. For example if user mapped class AF2x then it means that class AF21, AF22 and AF23 will be mapped for the corresponding priority.
Recommendations for EF Codepoint
EF traffic belongs to fast-track and guaranteed bandwidth service. It is the golden dream of any application requiring a "First Class" service, special for those that have to deal with real-time services. Real-time service traffic requires a very fast and safe service for the moving of data from sources to destinations.
In order to offer this kind of service, it is always recommended to map the EF traffic to higher priority.
Service type mapping
This page allows the user to map the predefined services to the corresponding priority.

DHCP Server Menu
The SPEEDLAN 9200 Configurator allows you to define a DHCP server on the Ethernet interface. A DHCP server is configured with a table of Ethernet addresses, ranges of IP
3-55
Part # 34357-MNL Rev. B SPEEDLAN 9200 User Guide
addresses and maps that are assigned to client network devices asking for the network settings. The DHCP server uses a "lease" to determine the length of time that a device or interface can use the assigned IP address.
Servers that utilize DHCP resolve security issues, costly IP addressing services, and compatibility problems. DHCP is a superset to BOOTP, which reduces the agony of assigning static IP addresses, and also provides advanced configuration options.
How DHCP Assigns an IP Address
This section explains how a DHCP server assigns an address. If you are familiar with this terminology, skip to Setting Up DHCP and DHCP Relay, page 3-57.
3-56
Figure 3-40: DHCP client and server
1 The client asks DHCP server for IP address and configuration if needed.
Note: The DHCP server allows IP addresses be assigned dynamically at the remote building. Distributing these administrative functions to each remote building significantly reduces the "administrative overhead" traffic that must travel back to the service provider's headquarters. A DHCP server is configured with a table of IP addresses that are assigned to client network devices asking for network settings. The DHCP server uses a "lease" to determine the length of time that a device or interface can use the assigned IP address.
2 The DHCP server assigns an available IP address to the client. 3 The client takes the IP address from DHCP server and requests for additional
configuration that is needed.

Important Note about DHCP
The DHCP Server serves IP addresses via the wireless interfaces in addition to the Ethernet interface. The DHCP Server does not serve other nodes on the same wireless cell.
For example, for Node A's DHCP server to serve IP addresses via its wireless interface, at least one of the following must be true:
Another SPEEDLAN 9200 router on the same cell has DHCP Relay enabled,
and configured to use Node A's DHCP server.
Beyond the Ethernet of a SPEEDLAN 9200 router on the same cell, there is a
router (wired or wireless) whose DHCP Relay is enabled and configured to use Node A's DHCP server.
