Features and Benefits

SPEEDLAN 9200 Features

The SPEEDLAN 9000 series introduces the second generation of wireless routers. The

SPEEDLAN 9200 offers the following new features:

• New Wireless Mode parameters (e.g., 5GHz OFDM, 2.4GHz DSSS or

2.4GHz OFDM), Preamble, Tx power and SSID). For more information, see Configuring the Radio Parameters, page 3-38.

• Double the transmission rate with turbo mode, up to 108Mb/s for 5GHz

OFDM. For more information, see Configuring the Radio Parameters, page 3-38.

• 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 4-5.

• 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 4-4.

1-2

• Provide DHCP relay: This first 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 maybe 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 3-50.

• Support for DC input sources: Devices that lack AC power will require DC-to-

DC supply.

• At this time, star mode (i.e., base, point-to-point and CPE)

is not available. Only mesh mode is available.

Page 11

SPEEDLAN 9200 User Guide Part # 34357-MNL Rev.03

The SPEEDLAN 9200 offers the network manager unsurpassed flexibility in meeting the

challenges of designing, building and managing today'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 Works

in Mesh Cells, page 1-6.

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.

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

SPEEDLAN 9200 User Guide Part # 34357-MNL Rev.03

• Hardware AES 128-bit encryption for security between SPEEDLAN 9200

routers.

• You can recover lost IP addresses. (Use IP Recover in SPEEDManage.)

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 Guide explains how encryption works with 9200 products in

A. Enabling Encryption Between SPEEDLAN 9200 Routers, page 4-4 and B. Enabling

WEP Security Between a SPEEDMesh-Enabled Client and SPEEDLAN 9200, page 4-4.

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 were received. This allows favoring network management,

VoIP and SCADA, over SMTP, ftp, and NNTP (for example).

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.

1-5

Page 14

Part # 34357-MNL Rev.03 SPEEDLAN 9200 User Guide

Queue 1 (the highest queue serviced) contains "management" traffic (i.e., RIP, Mesh,

K2, 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 remote 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.

Equipment and Hardware

For information about equipment and hardware, see SPEEDLAN 9200 Hardware,

page 2-1.

Figure 1-1: SPEEDView illustrating a mesh network (in SPEEDManage suite)

1-6

Page 15

SPEEDLAN 9200 User Guide Part # 34357-MNL Rev.03

SPEEDLAN 9200 routers provide the unique ability to "self-heal" the wireless network as

the topography changes over time, thereby increasing 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 1-6?

• 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 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.

Routing Around Obstacles

Page 16

Part # 34357-MNL Rev.03 SPEEDLAN 9200 User Guide

Explaining this scenario on the simplest level (using the Mesh protocol as shown in

Figure 1-2 on page 1-7). A can route a packet to B, despite the tree obstruction (block

of trees) within the path. How does this procedure work?

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, page 1-11).

SPEEDLAN’s Mesh Cell Architecture

Separate multi-user and residential models (SPEEDLAN 9201 for business and

residential use, as well as the SPEEDLAN 9204 for residential use) are specifically

designed to meet the connectivity demands for everyone from single users to large

corporations. SPEEDLAN 9201 and SPEEDLAN 9204 are mesh units. These models will

communicate with every other mesh router within an unobstructed radius of 1/2 mile

for SPEEDLAN 9201 and 1/4 mile for SPEEDLAN 9204.

1-8

Figure 1-3: An example of a mesh network

Page 17

SPEEDLAN 9200 User Guide Part # 34357-MNL Rev.03

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

respective 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 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.

1-9

Page 18

Part # 34357-MNL Rev.03 SPEEDLAN 9200 User Guide

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 order to send the datagram toward 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.

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 are

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.

Hardware Overview

The SPEEDLAN 9200 offers all the equipment you need to meet your connectivity

requirements:

• SPEEDLAN 9201: A router used in a non-line-of-sight pico cell (using the

Mesh protocol). This router contains an integrated 8 dBi, omni antenna (for

2.4 GHz only) which is directly attached on the top. You do not need an additional external antenna. The parameters are configured with the Mesh protocol in the SPEEDLAN 9200 Configurator. This type of self-healing Mesh topology process helps you reach buildings that do not have a clear line-ofsight back to a base station without the possibility of interference from hidden transmitters. For more information on this topic, see SPEEDLAN 9200 Mesh Protocol -- How It Works in Mesh Cells, page 1-6.

2-4

• SPEEDLAN 9202: This model can be configured as Customer Premise

Equipment (CPE) at one end of the point-to-point or point-to-multipoint link. It can be used with a 2.4GHz or 5GHz external antenna.

• SPEEDLAN 9203: This model is pre-configured as a base station but can be

reconfigured to function as a CPE router or as one end of a point-to-point or point-to-multipoint link. It can be used with a 2.4GHz or 5GHz 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 9205: This is similar to the SPEEDLAN 9202, but can be used only

in 2.4GHz and 5GHz mesh-only applications.

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.

Tips for Antenna Alignment

You are encouraged to use the transmit power test during installation if you have a

spectrum analyzer or power meter to measure the output for the antenna alignment.

For more information, see the SPEEDManage User Guide. The SPEEDSignal

application will also help installers align or position antennas on SPEEDLAN 9200

units.

Installation Steps for the SPEEDLAN 9201/SPEEDLAN 9204

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

fasten 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.

2-9

Page 30

Part # 34357-MNL Rev.03 SPEEDLAN 9200 User Guide

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.

Installation Steps for the SPEEDLAN 9202/SPEEDLAN 9203/ SPEEDLAN 9205

Generally, these routers follow the same general installation steps. Some installation

instructions are specific to customers who purchased Installation Kits from P-Com. To

view a diagram of the installation listed below, see Figure 2-9 on page 2-21.

If you are having trouble and need a full site installation, contact P-Com for services

and fees.

Antenna Selection Tip: Use a high-gain omni or sectoral antenna for a base station

(SPEEDLAN 9203), and use a grid or directional antenna for a CPE or point-to-point

router (SPEEDLAN 9202). Use an external omni antenna for the SPEEDLAN 9205.

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 procedure 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.

2-15

Page 36

Part # 34357-MNL Rev.03 SPEEDLAN 9200 User Guide

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 curvature 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.

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.

2-16

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.

Page 37

SPEEDLAN 9200 User Guide Part # 34357-MNL Rev.03

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.

Horizontal-Oriented Grid Vertical-Oriented

Grid

See also Tips for Antenna Alignment, page 2-5.

Figure 2-8: Grid antennas

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.

2-17

Page 38

Part # 34357-MNL Rev.03 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.

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 pressure that would cause the cable to kink or be stretched or

cut (i.e., pulling cable through tight locations).

f 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

2-18

Page 39

SPEEDLAN 9200 User Guide Part # 34357-MNL Rev.03

problems could occur. For more information on implementing this procedure,

see Weatherproofing Connectors, page 2-19.

g Next, ground the lightning arrestor. For more information, see Grounding the

Lightning Arrestor, page 2-19. You can also ground 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.

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.

2-19

Page 40

Part # 34357-MNL Rev.03 SPEEDLAN 9200 User Guide

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

VAC).

Step 9. Adding Additional Routers

Repeat the steps above for SPEEDLAN 9202/SPEEDLAN 9203/SPEEDLAN 9205 routers that will be communicating with this one.

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

3-2

Configuration of the SPEEDLAN 9200 is done through the SPEEDLAN 9200

Configurator. In order to access the SPEEDLAN 9200 Configurator, you must have:

Page 45

SPEEDLAN 9200 User Guide Part # 34357-MNL Rev.03

• a client workstation (e.g., PC, Mac, Sun),

• a compatible browser (Netscape Navigator 4+ or Internet Explorer 5+), and

• 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:

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.

Either end of the crossover cable can connect to the client PC or 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 User Guide Part # 34357-MNL Rev.03

Upon power up, a SPEEDLAN 9200 router that is not configured attempts to obtain an

IP address for its Ethernet LAN interface from a DHCP server. This is done by

broadcasting a "DHCPDISCOVER" message on that interface. If a suitably configured

and reachable DHCP server replies within 30 seconds, the SPEEDLAN 9200 will use

the IP address, netmask, (etc.) that the DHCP server provides. Otherwise, the

unconfigured SPEEDLAN 9200 will adopt a private network IP address 192.168.69.1

and a /24 netmask (255.255.255.0).

If a DHCP server is not used, it is recommended that the SPEEDLAN 9200 router and

the client PC be on the same subnet. Otherwise, the ability to configure intervening

routers may be required.

If the SPEEDLAN 9200 that is not configured and the client PC are on the same LAN,

their IP address should be configured compatibly (same IP network and netmask). This

can be accomplished by either:

1 The client PC obtaining its IP address from the same DHCP server as the

SPEEDLAN 9200.

2 Statically set the client's PC IP address to 192.168.69.x (x is in the range of 2 -

254) and its netmask to /24 (255.255.255.0).

• If you selected option #1 above, follow these general directions:

Open the Control Panel, and then double-click the Network and Dial-up Connections icon. Go to TCP/IP Protocol Properties to select the Obtain an IP address from a DHCP server option. Then, accept changes and close

this dialog box. Then, restart your computer.

• If you selected option #2 above, follow these general directions:

Open the Control Panel, and then double-click the Network and Dial-up Connections 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

(or the DHCP assigned address) at a command-line prompt. This ping command is

3-5

Page 48

Part # 34357-MNL Rev.03 SPEEDLAN 9200 User Guide

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. If using DHCP and DNS, it may be

possible to refer to the SPEEDLAN 9200 router by its name.

Note: SPEEDView gives you a "management" 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

3-6

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 three

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

In mesh mode, 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

Page 49

SPEEDLAN 9200 User Guide Part # 34357-MNL Rev.03

9200 Configurator. To reboot the router in the SPEEDLAN 9200 Configurator, choose

Reboot from the System menu (see Reboot, page 3-31).

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.

Classes of Users (and Passwords)

All software including the SPEEDLAN 9200 Configurator and SPEEDManage share the

same password(s). The only place where you change the password for all of these is in

the SPEEDLAN 9200 Configurator. For more information about SPEEDManage, see

the SPEEDManage User Guide.

There are five classes of users on the SPEEDLAN 9200. The classes are as follows with

their default passwords:

• Full Access (also known as a superuser): "wave_full" (this is also the only

access password for IP Recover in the SPEEDManage suite). Use this option when changing passwords. You cannot change the password to an existing password. Note: "Full Access" does not show up in "Admin/Users" because the user will not be able to change its permissions and it has write permission on everything.

• Wired Admin: "wave_wired_admin" (account for the private Ethernet network)

• Wired Read: "wave_wired" (account for the private Ethernet network)

• Wireless Admin: "wave_wireless_ad" (account for the wireless SPEEDLAN

9200 network)

• Wireless Read: "wave_wireless" (account for the wireless SPEEDLAN 9200

network)

Notes:

The minimum password length is 8 characters. The maximum password length is 16

characters (including the underscore character or spacebar). Any characters over the

maximum length (16) will be truncated. This rule applies for the Configurator and the

SPEEDManage suite.

Admin accounts have administration rights to their appropriate network (wired or

wireless), and Read Only accounts have only read only access.

If you are a network administrator and want to modify the default passwords and

settings for any of the users, choose the Admin menu. For more information, see

Protocol) server assigns the IP address to each computer as the computer connects to the network. If a computer moves to a new network, it must be assigned a new IP address for that network. DHCP can be used to manage these assignments automatically. Then, click Apply.

Optional: If you prefer, you can enter the client name of the host in the Client Hostname text box (under "Use DHCP"). The limit of the Client Hostname is

16 characters. (See also Important Note about DHCP, page 3-45.)

• Use this static address: Select this option if you want to statically assign an

IP 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

drop-down 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

updated. 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:

Page 65

SPEEDLAN 9200 User Guide Part # 34357-MNL Rev.03

1 Choose IP Addresses + Ethernet from the Network menu. Next, click the

Additional 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.

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

3-23

NAT rule. Version 3.0 and higher requires explicit creation of a virtual address prior to

referencing it. 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

figure, 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.

blank by default - you have to create one for the service to work. (If this entry is left blank, SNMP v1 or v2 service will be disabled.) The minimum number of characters entered is 1 and the maximum number of characters entered is 30. The default name is "public". If you want to use SNMP v1 or v2, enter the community name. Otherwise, leave this entry blank.

• Security Name (v3): This is the read-only 'user name' used for SNMP v3.

This entry should be set to a value that is only known by the network administrator. The minimum number of characters entered is 1 and the maximum number of characters entered is 30.

• Security Pass Phrase: This is the 'password' for SNMP v3. The minimum

number of characters entered is 8 and the maximum number of characters entered is 30.

Note: If you want to use SNMP v3, enter the Security Name and Security Pass Phrase.

Otherwise, leave these entries blank.

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.

appropriate values for the Wireless Mode you selected.

3 You can select a Long, or Short & Long preamble during the transmission

process between two or more systems from the Preamble drop-down list. This parameter specifies the preamble setting in 2.4GHZ DSSS mode. There are two types of preamble, short and long - referring to the length of the sync field. The default setting is Short & Long. This setting is useful when you cannot determine the field size of the data being sent. The system will sync itself for both short and long. Users should select a Long preamble when there is a lot of interference or noise on the network. (A short preamble is more likely to be used in stable links with low noise levels.) The field size of a long preamble is 128 bits and a short preamble is only 56 bits.

4 Select the appropriate channel from the Channel drop-down list. This is the

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.

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.

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.

3-41

Page 84

Part # 34357-MNL Rev.03 SPEEDLAN 9200 User Guide

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.

• 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 returns to the highest rate

3-42

SPEEDLAN 9200 User Guide Part # 34357-MNL Rev.03

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

transmitters.

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 discarded. (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 are 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 3-31: Max Throughput page

The Max Transmit Data Rate (in Kb/s) defaults are 29300 Kb/s for 2.4GHz & 5GHz

OFDM modes, and 6500 Kb/s for DSSS. The range is from 100 to 64,800 Kb/s (6.5

Mb/s).

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

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

How DHCP Assigns an IP AddressHow 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 3-45.

3-44

Figure 3-32: 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

Page 87

SPEEDLAN 9200 User Guide Part # 34357-MNL Rev.03

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.

4 DHCP server confirms IP address and configuration.

The SPEEDLAN 9200 Configurator allows you to assign IP addresses via DHCP on the

interfaces.

Setting Up DHCP and DHCP Relay

These instructions will explain how to:

• Configure and Manage the SPEEDLAN 9200 DHCP Server

• Configure DHCP Relay

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.

Configuring DHCP Relay

DHCP Relay allows you to configure the SPEEDLAN 9200 to relay (forward) any DHCP

requests originating on the Ethernet interface to a remote DHCP server. This allows you

to use existing DHCP servers to assign IP addresses and other configuration parameters

3-50

for SPEEDLAN 9200 routers via their wireless interfaces. If this service is enabled and

no DHCP servers are listed, the SPEEDLAN 9200 will relay DHCP requests to the DHCP

server that the SPEEDLAN 9200 used to get its interface address. If this service is

enabled and the SPEEDLAN 9200 did not use DHCP to get an address for its interface,

there must be at least one DHCP server address listed for this feature to work.

To add DHCP Relay information, do the following:

1 Choose DHCP Relay

Figure 3-37: Configuring DHCP Relay

from the DHCP menu. The following page will appear:

Page 93

SPEEDLAN 9200 User Guide Part # 34357-MNL Rev.03

2 Enter the following information:

• Disabled: Click to disable the DHCP Relay service.

• Enabled: Click to enable the DHCP Relay service.

• DHCP Servers: To enter a new DHCP server, enter the IP address and

click Add. This is the IP address of the DHCP server that is offering IP addresses to its clients.

• Delete: Click this button to remove information related to that DHCP

server address.

3 Once you have set up the SPEEDLAN 9200 router, configure the clients to

obtain an IP address from a DHCP server; do this on the PC and not on the

router! If the SPEEDLAN 9200 is the DHCP server, it will get the IP address

directly from it. If the DHCP server is located beyond the SPEEDLAN 9200

routers, the DHCP request will be forwarded to the DHCP server and then returned to the correct client machine.

If a SPEEDLAN 9200 router is serving as a DHCP relay and it has alias IP addresses,

the IP network information that the SPEEDLAN 9200 relays to the DHCP server will

always be that of the primary Ethernet IP.

Viewing Log Messages

If the DHCP server is not working properly, you can view system log messages by

choosing DHCP Server. Then, choose Log Messages. The page will display log

messages for the DHCP server. Timestamps are also reported in client time.

Timestamps track the date and time for each event in the log.

Forwarding Menu

Use this menu to control how traffic is forwarded through this router. These features are

available under the Forwarding menu:

• Queuing - Use this page to prioritize traffic out its wireless interface. Select the

Enabled option to activate the Priority Queuing feature. This feature is enabled by default. For more information, see Priority Queuing, page 3-52.

3-51

Page 94

Part # 34357-MNL Rev.03 SPEEDLAN 9200 User Guide

• Services - Defines a network service (e.g., web server, FTP and email server)

between the client and server nodes on your network. When you create a service, you will be allowed to forward public services inward to the internal (privately addressed) servers on your network. See Services, page 3-53.

• Address Sharing - Address Sharing uses Network Address Translation (NAT)

to allow you to share public IP addresses with privately addressed network nodes in order for them to access the Internet. See Address Sharing, page 3-58.

• Internal Servers - Allows an administrator to make a service available from

an IP address, even though the owner of the IP address may not be actually providing the service. See Internal Servers, page 3-60.

• 1:1 NAT - Allows an administrator to statically map a public IP address to the

private IP address of one of the nodes on your network. This is useful when trying to preserve a limited number of IP addresses on the WAN network. See 1:1 NAT, page 3-62.

• Firewall - The SPEEDLAN 9200 (via the SPEEDLAN 9200 Configurator)

allows you to control incoming and outgoing traffic. A firewall prevents

unauthorized access to a network. Utilizing the SPEEDLAN 9200 Configurator,

SPEEDLAN 9200 routers can increase security and provide additional support

to users of the network. See Firewall, page 3-63.

• lP Sessions - The SPEEDLAN 9200 firewall offers stateful packet filtering. IP

Sessions allows you to view sessions whose state is currently active. See IP Sessions, page 3-68.

Priority Queuing

Use this page to prioritize traffic out its wireless interface. Select the Enabled option to
