HTTP/HTTPS (Hypertext Transfer Protocol)

MAC address filtering

Extensible Authentication Protocol (EAP) support

1.4 Performance and Reliability Bandspeed wireless access point performance features ensure reliable and seamless connections for voice, video and data users whenever they roam.

The following describes the process that occurs when AirMaestro 3100AG Virtual Controller Access Points are being added to the network:

Access Point Registration: After powering up, each AirMaestro 3100AG Virtual Controller Access Point registers its participation in the network with the other AirMaestro 3100AG access points through a self-discovery process. Once registered, each access point bids for the right to perform the automated and intelligent channel selection and transmit power setting.

Access Point Bidding: Only one access point at a time wins the position to perform the auto-configuration process. Once awarded, the access point starts the Discovery process.

Discovery Process: During the Discovery process the access point scans every WLAN channel to detect other interfering access points within range. It scans all of the 2.4 GHz 802.11b/g channels using WIF-1. You can see this happen by watching the WLAN channel that WIF-1 is currently set to. Once WIF-1 completes the scan of the 2.4 GHz channels, WIF-3 starts scanning the 5 GHz 802.11a channels.

Interference Database Development: Through both scans, the access point develops an interference database that includes specific information on each interfering access point. This information includes SSID, Media Access Control (MAC) address, WLAN channel the interference was detected on, the receive signal strength RSS, and how many times packets were detected from the interfering access point.

Running/Bid_Denied: While one AirMaestro 3100AG Virtual Controller Access Point is in the Discovery process, the other access point has either completed auto-configuration (status displays as RUNNING) or is waiting to go through auto-configuration (status displays as BID_DENIED).

Optimal Channel Selection: After an access point completes the Discovery process, it runs an algorithm based on the information it accumulated in the interference database. This algorithm determines the optimal channel for that specific access point to select in the 2.4 GHz band on WIF-1. It performs the same calculation for channel selection for WIF-3 in the 5 GHz band.

Powerize Mode: The AirMaestro 3100AG Virtual Controller Access Point enters Powerize mode, where it communicates with other in-network 3100AG Access Points. These access points

1-3

communicate through the air to negotiate back their Transmit Power settings. This allows them to minimize co-interference while maximizing coverage and performance.

Dynamic Transmit Power Control: In the event an access point fails or is removed from the network, the other AirMaestro 3100AG Virtual Controller Access Point detects the absence of the access point and increases the transmit power to newly negotiated power levels.

1.5 Multiple Basic Service Set Identifier (BSSIDs) Multiple Basic Service Set Identifier support allows an access point to operate as multiple separate access points concurrently providing multiple wireless services to users in a network. Each BSSID can be configured to provide access to different network resources incorporating a unique virtual local area network (VLAN) and security settings per BSSID as desired.

For example, in an office environment, an access point (AP) could be used to offer three services. The first service provides access to protected data for office users that have been authenticated. The second service provides open Internet access to Guest Users in the Lobby while the third service provided VoIP access to employees with Wi-Fi enabled phones.

Each one of these can be configured to operate at the same time on a single Bandspeed access point, each providing different security and operational settings based on the needs of the service. Up to 16 BSSID’s per access point are available.

1.6 WDS Bridging and Spanning Tree Protocol (STP) Support A Distribution System (DS) is typically a wired network that interconnects multiple access points into a single local area network (LAN). A Wireless Distribution System (WDS) uses the wireless medium to interconnect separate access points.

A WDS link can be used to create simple point-to-point connection, a complex point-to-multipoint connection, or a multilayer topology.

1.7 Manageability of the AirMaestro 3100AG Virtual Controller Access Point

Bandspeed offers a variety of management support options for the AirMaestro 3100AG Virtual Controller Access Point, from Simple Network Management Protocol (SNMP) to Bandspeed's AirMaestro WLAN Management Console. Discussed in detail in this document are:

Bandspeed's AP Web UI Interface for Access Point Management (Section 5)

Bandspeed's Command Line Interface (CLI) for Access Point Management (Section 6)

1.7.1 Bandspeed AirMaestro WLAN Management Console The Bandspeed AirMaestro WLAN Management Console software (optional) was designed to ensure that deployment and ongoing management of your WLAN is simple and intuitive. In environments with an increasing amount of wireless interference and where performance of the wireless network is critical to your users, the features in the Management Console make it easy to deploy, manage, and utilize your wireless network.

Bandspeed's Listen+Learn technology simplifies the installation and management of one or more Bandspeed access points by automatically configuring the channel to transmit power settings for the access point(s).

Listen+Learn technology monitors RF activity in the environment of both Bandspeed and non-Bandspeed access points. This data is used to select optimal channel and transmit power settings for the Bandspeed access points, resulting in increased performance of your network's data transfer throughput.

1.7.2 Additional Features Included with the WLAN Management Console Software

Rogue access point detection, notification, and mitigation

Wizard-driven tools that simplify WLAN service deployment and modifications across the network

Remote monitoring and remote network management

Load balancing and fast roaming between access points, optimizing voice, data, and video transfer rates

1.7.3 Bandspeed AirMaestro WLAN Monitor Console The WLAN Monitor Console is a subset of the WLAN Management Console Software and, as a consequence, has a less robust feature set. The functions of the WLAN Monitor Console are detailed in the Bandspeed AirMaestro WLAN Management Console User Guide.

1.7.4 Installation Recommendations for the WLAN Management / WLAN Monitor Console Software

If you have both, you only need to install the WLAN Management Console software.

If you only have the WLAN Monitor Console software, then install that copy.

You can upgrade at a later time to the WLAN Management Console software. At that time, you can install it on the same system that is running the WLAN Monitor Console software.

1.8 Wireless Network Standards The following terms are used in this user guide and are defined by Wikipedia Encyclopedia (2007).

IEEE 802.11 Commonly known by the brand Wi-Fi, it denotes a set of WLAN standards developed by working group 11 of the IEEE LAN/MAN Standards Committee (IEEE 802). The term 802.11x is also used to denote the set of amendments to the standard. The term IEEE 802.11 is also used to refer to the original 802.11 (1997), which is now sometimes called "802.11 legacy."

802.11a The 802.11a amendment to the original standard was ratified in 1999. The 802.11a standard uses the same core protocol as the original standard, operates in 5 GHz band, and uses a 52-subcarrier orthogonal frequency-division multiplexing (OFDM) with a maximum raw data rate of 54 megabits per second (Mbps), which yields realistic net achievable throughput in the mid-20 Mbps.

Because the 2.4 GHz band is heavily used, using the 5 GHz band gives 802.11a a significant advantage. However, this high carrier frequency also brings a slight disadvantage: the effective overall range of 802.11a is slightly less than that of 802.11b/g; 802.11a signals cannot penetrate as far as those for 802.11b because they are absorbed more readily by walls and other solid objects in their path. On the other hand, OFDM has fundamental propagation advantages when in a high multipath environment, such as an indoor office. The higher frequencies enable the building of smaller antennae with higher RF system gain, which counteract the disadvantage of a higher band of operation.

802.11b The 802.11b amendment to the original standard was ratified in 1999. 802.11b has a maximum raw data rate of 11 Mbps and uses the same carrier sense multiple access with collision avoidance (CSMA/CA) media access method defined in the original standard. Due to the CSMA/CA protocol overhead, in practice the maximum 802.11b throughput that an application can achieve is about 5.9 Mbps using Transmission Control Protocol (TCP) and 7.1 Mbps using User Datagram Protocol (UDP).

802.11b is normally used in a point-to-multipoint configuration, wherein an access point communicates via an omni-directional antenna with one or more clients located in a coverage area around the access point. Typical indoor range is 30 meters (100 feet) at 11 Mbps and 90 meters (300 feet) at 1 Mbps. The overall bandwidth is dynamically shared across all the users on a channel. With high-gain external antennas, the protocol can also be used in fixed point-to-point arrangements, typically at ranges up to 8 kilometers (5 miles).

802.11b cards can operate at 11 Mbps but scale back to 5.5, then 2, and then 1 Mbps (also known as Adaptive Rate Selection) if signal quality becomes an issue. Because the lower data rates use less complex and more redundant methods of encoding the data, they are less susceptible to corruption due to interference and signal attenuation.

802.11g In June 2003, a third modulation standard was ratified: 802.11g. This works in the 2.4 GHz band (like 802.11b) but operates at a maximum raw data rate of 54 Mbps, or about 19 Mbps net throughput.

Although 802.11g operates in the same frequency band as 802.11b, it can achieve higher data rates because of its similarities to 802.11a. The maximum range of 802.11g devices is slightly greater than that of 802.11a devices.

Despite its major acceptance, 802.11g suffers from the same interference as 802.11b in the already crowded 2.4 GHz range. Devices operating in this range include microwave ovens, Bluetooth devices, baby monitors and cordless telephones. Interference issues and related problems within the 2.4 GHz band have become a major concern and frustration for users.

2.2 Safety Information Warnings contain directions that you must follow for your personal safety. Follow all directions carefully. You must read the following safety information carefully before you install or remove the access point.

Warning: To comply with FCC RF exposure limits, a minimum of body-to-antenna distance of 8 inches must be maintained when the access point is in the ON position.

Warning: The equipment must be installed in compliance with national and local building codes, FCC rules, and regulatory restrictions. Only professional network personnel should install the access points, antennas, and cables.

Warning: If you supply your own Ethernet cable, make sure that it is CAT5 straight-through (8-wire) that has not been altered in any way. A non-standard Ethernet cable may damage the access point.

Warning: Disconnect the power adapter before moving the unit.

2-1

Warning: If using the supplied DC power supply to provide power to the access point, the socket outlet must be near the unit and easily accessible. You can only remove power from the access point by disconnecting the power cord from the outlet or disconnecting the PoE cable.

Warning: There are no user-replaceable fuses or user serviceable parts inside the access point. If you have a physical problem with the unit that cannot be solved with problem solving actions in this guide, contact your supplier.

Warning: To avoid damage to the equipment or possible personal injury, you must use the supplied power supply or IEEE 802.3af-compliant power supply equipment that is safety certified according to UL, CSA, IEC, or other applicable national or international safety requirements for the country of use.

Warning: It is the responsibility of the installer to make sure that the PoE power supply is properly connected. Connection to any other device may result in permanent damage to the access point, electric shock, or fire. Refer to the installation instructions for proper installation.

2.3 Determining the Correct Site One of the major advantages of the AirMaestro 3100AG Virtual Controller Access Point is that it greatly simplifies the site selection process. To optimize performance, locate the 3100AG Access Point in the center of the distribution of your users, assuming they are fairly evenly distributed throughout your environment. Bandspeed's Listen+Learn technology can help mitigate interference and provide load balancing; this consideration for site selection is not critical.

2.4 Avoiding Reflective Surfaces The most important concern in the selection of a mounting site is the avoidance of walls, ceilings, floors, and metal surfaces close to the AirMaestro 3100AG Virtual Controller Access Point. These surfaces tend to reflect RF signals and, if they are close, reflect strong signals. This results in more interference and therefore poorer signal quality.

Wherever possible, keep the AirMaestro 3100AG Virtual Controller Access Point 10 to 20 feet from walls. Optimally, you should place it at a height equidistant from the ceiling and floor (tabletop mount).

2.5 Minimizing Interference The Bandspeed Listen+Learn software enables the AirMaestro 3100AG Virtual Controller Access Point to operate efficiently even in the presence of interfering signals. However, when determining ideal placement, avoid the following devices:

802.11b, 802.11g, and Bluetooth access points

2.4 GHz (gigahertz) cordless telephones

2.4 GHz wireless cameras, area monitors, and similar devices

Microwave ovens in regular use

2-2

2.6 RF Obstacles RF signals at 2.4 GHz do not easily pass through obstacles. Depending on the construction material used, walls between the AirMaestro 3100AG Virtual Controller Access Point and the intended station(s) attenuate the signal, thereby reducing the effective range. Therefore, place the 3100AG Access Point so that signals travel through as few walls as possible, especially if the walls have significant metal content or foil-backed insulating materials.

Signals traverse floors and ceilings, so it is possible to cover more than one floor with a single AirMaestro 3100AG Virtual Controller Access Point. However, floors can be severe attenuators, so you should expect reduced range in this configuration.

2.7 Power and Network Connections The ideal location must also provide for power and network connections for the AirMaestro 3100AG Virtual Controller Access Point. Because it is IEEE 802.3af-compliant, a single PoE cable provides the power and network connection. If you do not use PoE LAN equipment, place the 3100AG Access Point near an AC power source for the external power supply.

2.7.1 PoE Connection When connected to an IEEE 802.3af-compliant powered switch, the AirMaestro 3100AG Virtual Controller Access Point receives all required power from the switch. No external power supply is required. Once the PoE cable is connected to the 3100AG Access Point, the unit begins initialization, which takes approximately one minute.

2.7.2 Using the External Power Supply If you are not using powered Ethernet, the AirMaestro 3100AG Virtual Controller Access Point is powered by the external power supply (included). Plug the external supply into an AC source (100-250 V, 50-60 Hz), and then plug the DC side into the 3100AG Access Point's external power supply connector. The unit initializes within approximately one minute.

Before You Begin: Record each of the access point’s MAC address in a safe space before the access point is installed in a difficult to reach location. The access point’s MAC address is located on the bottom underneath side of the access point housing.

2-3

2.8 Configuring the AirMaestro 3100AG Virtual Controller Access Point Using the Serial Port

The serial port is RS-232C-compliant. It is recommended for Advanced Wireless Users. Once the settings for the wired Ethernet port and the wireless interfaces are set to work with your network, you may use any one of them (serial port, Ethernet port, or wireless) for configuration changes or access point management. Be sure that the serial port settings of the attached terminal device are the same as those of the AirMaestro 3100AG Virtual Controller Access Point, as listed in Table 2-1.

3.3 Configuring the Access Point The following sections show you how to configure the access point, with or without a DHCP server.

3.3.1 Factory Default Settings The AirMaestro 3100AG Virtual Controller Access Point is configured at the factory to obtain an Internet Protocol (IP) address automatically using DHCP; if no DHCP server is detected on the network the access point falls back to a default static IP address (192.168.1.1).

Note: If the access point fails to acquire an IP address using DHCP refer to the Without a DHCP Server section in this guide.

3.3.2 With a DHCP Server If your network uses a DHCP server for automatic IP address acquisition, no action is required. To determine which IP address the DHCP server assigned to the AirMaestro 3100AG Access Point(s), run the WLAN Monitor Console. The Network View screen shows access points represented by large, colored circles, as shown in Figure 3-14. A green triangle represents the Bandspeed access point.

Figure 3-14: AirMaestro WLAN Monitor Console, Network View screen.

To view information about an access point, such as the Ethernet MAC address and IP address assigned by the DHCP server, left click on the AirMaestro access point icon (small green triangle). The Access Point Details dialog box opens, as shown in Figure 3-15.

3-9

Figure 3-15: Access Point Details dialog box.

Note: You can also find the Ethernet MAC address on the AirMaestro 3100AG Virtual Controller Access Point enclosure.

Connect to the AP Web UI Interface To perform configuration of AirMaestro 3100AG Virtual Controller Access Points, you will need to connect to each access point's Web User Interface. If you have installed the WLAN Management Console, consult the WLAN Management Console documentation as much of the configuration features can be accomplished through the Management Console.

Right-click on the access point's icon (green triangle, shown in Figure 3-16a), and select Connect to AP Web UI Interface from the shortcut menu that appears, as shown in Figure 3-16b.

AirMaestro 3100AG Virtual Controller Access Point Configurable Parameters 4

This section provides details of the configurable parameters accessible through the AP Web UI Interface (described in Section 5) or Command Line Interface (CLI) (described in Section 6). Section 4 focuses on the effects of the parameters and situations in which you may want to change them.

Each configurable parameter has an associated application programming interface (API) function that provides access to modify it. Both the CLI and HyperText Transfer Protocol (HTTP) methods of changing a particular parameter access the same API function. The user interfaces are different (see the sections on CLI and AP Web UI Interface); however, the underlying mechanisms are the same.

4.1 Wireless Interfaces (WIFs or Sectors) The term wireless interface or sector, when used in conjunction with the AirMaestro 3100AG Virtual Controller Access Point, represents a wireless interface consisting of radio, baseband, and MAC components. The terms wireless sector and wireless interface (WIF) are used interchangeably.

The AirMaestro 3100AG Access Point has three wireless interfaces, each of which can function as an access point.

Each of the three interfaces has a number of configurable parameters that can impact operation of the radio, baseband, or MAC components. The use of each parameter is discussed below. See the CLI or AP Web UI Interface sections for information on setting parameters.

4.2 Mode You may set each wireless interface to operate in one of four IEEE 802.11 modes: 11a, 11b, 11b/g, or 11g. However, switching modes may produce side effects. For example, switching from 11a to 11b mode causes the selection of a new default channel appropriate to that mode. The following sub-sections provide details on each mode.

4.2.1 11a Mode The 11a mode selects the 5 GHz band (channels 36, 40, 44, 48, and so on). The 5 GHz band has the advantages of less interference than the 2.4 GHz band, and data rates up to 54 Mbps (megabits per second). Setting the mode of a wireless interface to 11a restricts associations on that interface to stations operating in the 11a mode.

4.2.2 11b Mode The 11b mode selects the 2.4 GHz band (channels 1 through 11). The 2.4 GHz band is considerably more congested than the 5 GHz band and is limited to data rates up to 11 Mbps. Setting the mode of a wireless interface to 11b restricts associations on that interface to stations operating in 11b mode.

Select 11b mode when the Basic Service Set (BSS) needs to support only 11b stations.

4-1

4.2.3 11b/g Mode 11b/g mode selects the 2.4 GHz band (channels 1 through 11) in "mixed" mode operating environment. The 2.4 GHz band is considerably more congested than the 5 GHz band and is limited to data rates up to 11 Mbps for 11b stations and 54 Mbps for 11g stations.

Note that the overall throughput for a station operating in mixed mode may be significantly lower, due to 11g protection mode (self-CTS), 11g protection mode adds some overhead to 11g transmissions to prevent them from impacting legacy 11b traffic. The AirMaestro 3100AG Virtual Controller Access Point (and participating 11g stations) automatically engage in this mode, when required. The result of engaging in protection mode is that the performance of 11g stations is substantially reduced. (See Section 4.4 regarding the discussion of self-CTS.)

Select 11b/g mode when the BSS needs to support both 11b and 11g stations.

4.2.4 11g Mode The 11g mode selects the 2.4 GHz band (channels 1 through 11) in "pure g" mode. The 2.4 GHz band is considerably more congested than the 5 GHz band and is limited to data rates up to 54 Mbps.

Note: "Pure g" mode assumes there are no 11b stations operating in the BSS and that protection mode (self-CTS) is not required. This allows the interface to operate at optimal efficiency, achieving throughput similar to 11a mode in the 5 GHz band, depending on local interference in the selected channel.

Select 11g when the BSS needs to support only 11g stations and not 11b stations.

4-2

4.3 Channel Selection of a particular mode results in selection of a default channel for that mode. Depending on interference and congestion in the default channel, it may or may not yield optimal performance. You may experiment with manual channel selection to try to improve throughput.

Note: Avoid channel 6 in the 2.4 GHz band. Many access points are set to that channel by default, and it tends to be more congested.

If the Listen+Learn feature is enabled, the process of channel selection is continuous and fully automatic. The AirMaestro 3100AG Virtual Controller Access Point monitors for interference in all channels and stays on the current channel or switches channels if overall performance would benefit from the switch. Bandspeed recommends enabling Listen+Learn rather than manually selecting channels.

4.4 Self-CTS (11g Protection Mode) 11g Protection Mode is automatically enabled whenever both 11g and 11b stations interoperate within a BSS. The IEEE 802.11g standard requires that this be fully automatic.

Turning off 11g Protection Mode is an option for 11g ("pure g") mode if you want to eliminate the possibility that use of self-CTS is adversely affecting 11g throughput (for benchmarking and other purposes). However, there is no other need to change this parameter.

4.5 Transmit Power The Transmit Power setting determines the power level in decibel milliwatts (dBm) that frames will be transmitted. The Transmit Power level must be carefully balanced with the Maximum Data Rate to avoid distortion.

For example, setting the Transmit Power to 20 dBm with the Maximum Data Rate at 54 Mbps will likely result in distortion and therefore failed attempts to transmit. Lowering the Transmit Power or the Maximum Data Rate will eliminate the distortion, thus a Transmit Power of 20 dBm works more efficiently with a Maximum Data Rate of 48 Mbps or 36 Mbps.

Note: If you elevate the Transmit Power to reach a distant station, you may need to lower the Maximum Data Rate to avoid distortion.

Normally, you should not adjust this parameter because it is overridden by the default Automatic Transmit Power Adjustment setting.

4-3

4.6 Automatic Transmit Power Adjustment The Automatic Transmit Power Adjustment parameter determines the behavior of the AirMaestro 3100AG Access Point device driver with respect to transmit power limitation. It defaults to a setting of Max54, which ensures that the device driver never transmits a frame with a transmit power level too high for the data rate. This setting overrides the Transmit Power value in dBm.

Bandspeed recommends you leave the default Max54 setting. This guarantees the 3100AG Access Point never transmits a distorted frame due to an excessive transmit power level (optimizes range and throughput together).

If the Listen+Learn feature is enabled, the process of Transmit Power Adjustment is continuous and fully automatic. The 3100AG Access Point monitors all channels and adjusts its transmit power setting to accommodate in-network 3100AG Access Points. Enabling Listen+Learn is recommended over manual transmit power selection.

4.7 Sensitivity The Sensitivity parameter determines how sensitive a wireless interface radio is to receiving low-energy signals. A low-energy signal could be a distant station that is legitimately trying to associate with the AirMaestro 3100AG Virtual Controller Access Point. It could also be cross-interface interference from another wireless interface on the same 3100AG mini-PCI (Peripheral Component Interconnect) board. This can occur when you are running two or three interfaces in the same mode (all in 11g, for example) on adjacent channels.

The Sensitivity parameter is set to High by default, to ensure that distant stations are "heard" by the AirMaestro 3100AG Virtual Controller Access Point. If you know all stations needing network access through the 3100AG Access Point are relatively close (in the same room, for example), you may set the Sensitivity setting to Medium or Low.

However, Sensitivity is an advanced tuning parameter that you normally do not need to change from its default High setting. Avoid changing it unless you suspect cross-interface interference between two or more interfaces on your 3100AG mini-PCI board.

4.8 Maximum Data Rate The Maximum Data Rate parameter limits the data rate used on an AirMaestro 3100AG Virtual Controller Access Point interface. It defaults to the maximum rate allowed for an operating mode (for example, 54 Mbps for 11a and 11g, and 11 Mbps for 11b).

You typically do not need to modify the maximum data rate, except for a situation in which high transmit power levels are required to reach distant stations. In this case, a data rate of 54 Mbps might not be achievable at a high power level, such as 20 dBm (due to distortion). Therefore, set the maximum data rate to a lower setting, such as 48 Mbps or 36 Mbps.

The AirMaestro 3100AG Virtual Controller Access Point software's auto-rate-adjusting algorithm works around the problem with high transmit power by re-transmitting at a lower data rate when a higher data rate fails. However, this is not as efficient as avoiding the failing data rate altogether.

Note: In cases where the transmit power needs to be set higher than normal to reach distant stations, it may be necessary and will be more efficient for you to reduce the maximum date rate to account for the potential distortion at the default maximum data rate.

See the discussion of Transmit Power for more information.

4-4

4.9 Diversity The Diversity parameter controls the use of antennas on the AirMaestro 3100AG Virtual Controller Access Point. Each wireless interface has a primary antenna (Antenna 1, default) and a secondary antenna (Antenna 2). You can manually select either antenna for an interface. The setting applies to receive and transmit operations.

Setting the Diversity parameter to Both causes the device driver to alternately try each antenna, eventually settling on the antenna that yields the best performance.

4.10 Header (Preamble) The Header parameter determines the default preamble type that the AirMaestro 3100AG Virtual Controller Access Point MAC uses to transmit in 11b mode. It has no meaning in orthogonal frequency-division multiplexing (OFDM) modes (11g or 11a).

In 11b mode, a long preamble length allows the receiving side greater time to sync-up on the incoming frame (144 microseconds is a long preamble length; 72 microseconds is a short preamble length). The 3100AG Access Point receives 11b frames transmitted by a station with either long or short preamble lengths and responds to (acknowledges) received frames using the same preamble length as the received frame. To summarize:

The header parameter is specific to 11b mode.

It determines how the 3100AG Access Point transmits 11b frames.

It takes 72 microseconds longer to transmit an 11b frame with a long preamble.

Using a long preamble length may achieve greater interoperability with legacy 11b stations.

4.11 Beacon Interval The Beacon Interval parameter is the period in milliseconds between beacon transmissions in a BSS. You can adjust this parameter higher or lower as required; however, adjusting it to too high a value may cause stations to disassociate (station-dependent).

Note: This parameter value is set to 100 time units (TUs) by default, and you should not need to modify it.

4.12 Fragmentation The Fragmentation parameter determines whether or not the AirMaestro 3100AG Virtual Controller Access Point MAC fragments frames into smaller pieces, as indicated by the Fragmentation Threshold parameter. Typically, fragmentation occurs to ensure that frames are transmitted cleanly on the first try, by reducing the number of continuous bits transmitted and thereby the likelihood of a transmission error.

Fragmentation overhead is significant, due to the acknowledgement required for every fragment (as opposed to a single acknowledgement for the complete frame). Typically, modern auto-rating algorithms obviate fragmentation, although there may be extreme cases where you can achieve better throughput using fragmentation. If you are in this situation, you may have a serious network problem to correct.

Ordinarily, you should not have to modify this parameter. However, you may want to modify it as an experiment or if you (or another wireless expert) have determined that fragmentation will solve a specific problem.

4-5

4-6

4.13 RTS/CTS The Request to Send / Clear to Send (RTS/CTS) parameter determines whether the AirMaestro 3100AG Virtual Controller Access Point MAC will initiate an RTS/CTS sequence preceding transmission of certain data frames, as indicated by the RTS/CTS Threshold parameter. Typically, RTS/CTS exchanges are performed to ensure the medium is clear prior to transmitting data -- to avoid the "hidden node problem."

RTS/CTS overhead is significant due to the RTS and CTS transmission times and the Short Interframe Spacing (SIFS) times between them.

Ordinarily, you should not have to modify this parameter. However, you may want to modify it as an experiment or if you (or another wireless expert) have determined that use of RTS/CTS will solve a specific problem, such as the hidden node problem.

4.14 Wireless (Interface) Operating Mode Leave this parameter at the Normal setting, unless you have a specific need to use the interface for spectrum analysis.

Note: Setting this parameter to Spectrum Analyzer disables all access point functionality previously running on that interface.

AP Web UI Interface to Configure Access Points 5 The AP Web UI Interface provides the simplest means for configuring and managing the Bandspeed AirMaestro system. You can access it through the wired Ethernet connection or the wireless interface.

The IP address of the client device (Ethernet NIC or wireless NIC) should be set to an address in the same subnet as the AirMaestro 3100AG Virtual Controller Access Point. For example, if the 3100AG Access Point is set to IP address 192.168.1.1, the NIC should be set to 192.168.1.x, where x is a number between 2 and 255, so that the full IP address does not conflict with another device in the subnet.

To access the interface:

1. Open a Web browser, and then enter the address of the Bandspeed AirMaestro system (for example, http://192.168.1.1). The Authentication Required dialog box opens.

2. Type admin in the User Name text box, type Bandspeed in the Password text box, and then click on OK. (The user name and password are case-sensitive.)

Every AirMaestro 3100AG Virtual Controller Access Point has three wireless interfaces. You can configure each wireless interface for a different wireless mode.

The modes are as follows:

11a: Provides service for 802.11a (5.0 GHz)

11b: Provides service for 802.11b (2.4 GHz)

11bg: Provides service for 802.11b and 802.11g (2.4 GHz)

11g: Provides service for 802.11g (2.4 GHz)

Monitor: Provides WLAN and RF monitoring (2.4 GHz and 5.0 GHz)

AirMaestro 3100AG Access Points support any configuration of WIFs. However, for optimal performance, Bandspeed recommends running only one WIF in the 2.4 GHz space (this does not include the Monitor WIF). The default configuration is: WIF-1 = 11bg, WIF-2 = Monitor, WIF-3 = 11a.

Basic Configuration >> Services

Figure 5-14: Basic Configuration >> Services page.

A service is a wireless service deployed with a specific SSID and security settings. AirMaestro 3100AG Virtual Controller Access Points support up to 16 services deployed on each access point. You can deploy services across any or all WIFs. Each service will appear to wireless clients as an independent wireless network.

There are two types of services available on AirMaestro 3100AG Access Points: data services and voice services. Data services are traditional wireless services designed for normal wireless use. Voice services enable fast roaming across multiple access points in a cluster to provide seamless wireless coverage for VoIP Wi-Fi phones. Voice services also provide load balancing and load management. Voice services are not limited to just VoIP phones; they can be used by any device looking for the benefits of fast roaming and load balancing.

Command Line Interface (CLI) to Configure Access Points 6

6.1 Using the CLI This section explains the CLI commands you can use to configure the AirMaestro 3100AG Virtual Controller Access Point and display configuration settings.

Note: Although you can use the CLI to change settings while the 3100AG Access Point is running, it is recommended you stop the system before making changes and then restart it after the changes are completed. Changes do not take effect until the access point is restarted. The 3100AG Access Point uses multiple NICs that require significant processor power while running, which limits the time available to the CLI and causes it to miss occasional characters.

6.2 Command Conventions The commands are shown using the following conventions:

Triangular brackets (< >) indicate a required choice.

Square brackets ([ ]) indicate optional items.

Vertical bars ( | ) separate mutually exclusive choices.

Boldface indicates commands and keywords that are entered exactly as shown.

Italics indicates values you must supply.

Examples Examples show screen displays and the command line in the screen font.

Information you need to enter in examples are shown in boldface font.

Variables that you must supply are shown in italic font.

6.13 Bridge Commands - Wireless Bridging/Backhaul The Bandspeed AirMaestro system supports a flexible wireless bridging technology. The system supports up to 16 wireless bridge links on each WIF, and up to 48 total on the AirMaestro 3100AG Virtual Controller Access Point. You can use wireless bridging to form Mesh-Networks with other Bandspeed 3100AG Access Points by allocating multiple bridge endpoints on an access point with a desired Service Set Identifier (SSID). These bridge endpoints automatically discover other endpoints with the same SSID, and then establish bridges on the fly. Spanning Tree Protocol (STP) runs to prevent forwarding loops.

bridge add wif<1|2|3> <ssid>

Adds a bridge to wif<1|2|3> with the specified SSID. By default, mode is set to manual.

bridge del wif<1|2|3> <ssid>

Deletes the specified bridge endpoint SSID from the specified WIF. This disconnects any connected bridge endpoints using this SSID.

bridge wif<1|2|3> <ssid> ssid <new-ssid>

Changes the SSID of a particular bridge.

bridge wif<1|2|3> <ssid> passphrase <string>

Sets the passphrase to encrypt the wireless backhaul link, which must be the same on all bridge endpoints using this SSID.

bridge wif<1|2|3> dot1q [enabled | disabled]

Enables/disables 802.1Q VLAN tagging on the wireless bridge.

bridge wif<1|2|3> <ssid> security <enabled|disabled>

Enables the use of Counter CBC-MAC Protocol (CCMP) encryption on the wireless bridge. This utilizes the pre-shared key specified in the passphrase command.

bridge wif<1|2|3> <ssid> mode <auto <num> |manual>

Sets the mode of the bridge SSID. If set to manual, only one bridge endpoint is allocated/configured on the WIF. If set to auto, multiple bridge endpoints (up to 16) are allocated on the WIF, allowing the access point to form up to 16 wireless bridges.

The SWITCH command is used to configure the Switch module.

You can set the following Switch parameters:

ale

Address look-up engine; allows the switch module to look up a MAC address in its address table to determine which port to forward the frame.

ingresswifpktstoeth

Disables port to port forwarding between the wireless interfaces. It effectively forces all incoming frames on any wireless port to be forwarded out to the Ethernet port.

6.21 RRM Commands - Radio Resource Measurement IEEE 802.11k is a proposed standard for radio resource management. It defines and exposes radio and network information to facilitate the management and maintenance of a mobile WLAN. IEEE 802.11k and IEEE 802.11r are the key industry standards now in development that will enable seamless Basic Service Set (BSS) transitions in the WLAN environment. The 802.11k standard provides information to discover the best available access point.

802.11k is intended to improve the way traffic is distributed within a network. In a wireless LAN, each device normally connects to the access point (AP) that provides the strongest signal. Depending on the number and geographic locations of the subscribers, this arrangement can sometimes lead to excessive demand on one AP and underutilization of others, resulting in degradation of overall network performance. In a network conforming to 802.11k, if the AP having the strongest signal is loaded to its full capacity, a wireless device is connected to one of the underutilized APs. Even though the signal may be weaker, the overall throughput is greater because more efficient use is made of the network resources.

- 802.11k standard per Wikipedia, Section 2.02

The RRM (Radio Resource Measurement) command is used to configure Radio Resource Measurement parameters.

Definitions Hidden nodes in a wireless network refer to nodes that are out of range of other nodes or a collection for nodes. Take a physical star topology with an access point with many nodes surrounding it in a circular fashion; each node is within communication range of the access point. However, not every node can communicate with each other. For example, it is likely that the node at the far edge of the circle can see the access point, which is known as r, but it is unlikely that the same node can see a node on the opposite end of the circle, 2r (or simply the diameter). These nodes are known as hidden. The problem is when node r and r2 start to send packets simultaneously to the access point. Because node r and r2 cannot sense the carrier, carrier sense multiple access with collision avoidance (CSMA/CA) does not work.
