Sample Configuration Tasks
This section provides examples of some of the common configuration tasks used
with the Wi-Fi Array, including:
“Configuring a Simple Open Global SSID” on page 292.
“Configuring a Global SSID using WPA-PEAP” on page 293.
“Configuring an SSID-Specific SSID using WPA-PEAP” on page 294.
“Enabling Global IAPs” on page 295.
“Disabling Global IAPs” on page 296.
“Enabling a Specific IAP” on page 297.
“Disabling a Specific IAP” on page 298.
“Setting Cell Size Auto-Configuration for All IAPs” on page 299
“Setting the Cell Size for All IAPs” on page 300.
“Setting the Cell Size for a Specific IAP” on page 301.
“Configuring VLANs on an Open SSID” on page 302.
“Configuring Self-Monitoring Mode (Loopback Tests)” on page 303.
To facilitate the accurate and timely management of revisions to this section, the
examples shown here are presented as screen images taken from a Secure Shell
(SSH) session (in this case, PuTTY). Depending on the application you are using
to access the Command Line Interface, and how your session is set up (for
example, font and screen size), the images presented on your screen may be
different than the images shown in this section. However, the data displayed will
be the same.
Some of the screen images shown in this section have been modified for clarity.
For example, the image may have been “elongated” to show all data without the
need for additional images or scrolling. We recommend that you use the Adobe
PDF version of this User’s Guide when reviewing these examples—a hard copy
document may be difficult to read.
As mentioned previously, the root command prompt is determined by the host
name assigned to your Array.

Setting Cell Size Auto-Configuration for All IAPs
This example shows how to set the cell size for all enabled IAPs to be autoconfigured (auto). (See “Fine Tuning Cell Sizes” on page 35.) The auto_cell option
may be used with global_settings, global_a_settings, or global_bg_settings. It
sets the cell size of the specified IAPs to auto, and it launches an autoconfiguration to adjust the sizes. Be aware that if the intrude-detect feature is
enabled on abg2, its cell size is unaffected by this command. Also, any IAPs used
in WDS links are unaffected.
Auto-configuration may be set to run periodically at intervals specified by
auto_cell period (in seconds) if period is non-zero. The percentage of overlap
allowed between cells in the cell size computation is specified by auto_cell
overlap (0 to 100). This example sets auto-configuration to run every 1200 seconds
with an allowed overlap of 5%. It sets the cell size of all IAPs to auto, and runs a
cell size auto-configure operation which completes successfully.

Setting the Cell Size for All IAPs
This example shows you how to establish the cell size for all IAPs (radios),
regardless of the wireless technology they use. Be aware that if the intrude-detect
feature is enabled on abg2 the cell size cannot be set globally—you must first
disable the intrude-detect feature on abg2.
In this example, the cell size is being set to small for all IAPs. You have the option
of setting IAP cell sizes to small, medium, large, or max. See also, “Fine Tuning
Cell Sizes” on page 35.

The Command Line Interface
Wi-Fi Array
Configuring Self-Monitoring Mode (Loopback Tests)
The Array uses the built-in monitor radio (IAP abg2) to monitor other radios in
the Array. Tests include sending probes on all channels and checking for a
response, and checking whether beacons are received from the other radio. If a
problem is detected, corrective actions are taken to recover. Loopback mode
operation is described in detail in “Array Monitor and Loopback Testing
Capabilities” on page 341.
The following actions may be configured:
alert-only—the Array will issue an alert in the Syslog.
repair-without-reboot—the Array will issue an alert and reset radios at
the Physical Layer (Layer 1) and possibly at the MAC layer. The reset
should not be noticed by users, and they will not need to reassociate.
reboot-allowed—the Array will issue an alert, reset the radios, and
schedule the Array to reboot at midnight (per local Array time) if
necessary. All stations will need to reassociate to the Array.
off—Disable IAP loopback tests (no self-monitoring occurs). Loopback
tests are off by default.
This is a global IAPs setting—abg2 will monitor all other radios according to the
settings above, and it cannot be set up to monitor particular radios. Selfmonitoring mode requires Intrusion Detection to be set to Standard.
The following example shows you how to configure a loopback test.

Appendix C: Technical Support
This appendix provides valuable support information that can help you resolve
technical difficulties. Before contacting Xirrus, review all topics below and try to
determine if your problem resides with the Wi-Fi Array or your network
infrastructure. Topics include:

General Hints and Tips
This section provides some useful tips that will optimize the reliability and
performance of your Wi-Fi Arrays.
The Wi-Fi Array requires careful handling. For best performance, units
should be mounted in a dust-free and temperature-controlled
environment.
If using multiple Arrays in the same area, maintain a distance of at least
100 feet (30m) between Arrays if there is direct line-of-sight between the
units, or at least 50 feet (15 m) if a wall or other barrier exists between the
units.
Keep the Wi-Fi Array away from electrical devices or appliances that
generate RF noise. Because the Array is generally mounted on ceilings, be
aware of its position relative to lighting (especially fluorescent lighting).
If using AC power, each Wi-Fi Array requires its own dedicated AC
power outlet. Do not attempt to “piggy-back” AC power to multiple
units. To avoid needing to run separate power cables to one or more
Arrays, consider using Power over Gigabit Ethernet.
Appendix C: Technical Support
333
Wi-Fi Array
If you are deploying multiple units, the Array should be oriented so that
the abg2 radio is oriented in the direction of the least required coverage,
because when in monitor mode the abg2 radio does not function as an AP
servicing stations.
The Wi-Fi Array should only be used with Wi-Fi certified client devices.

Frequently Asked Questions
This section answers some of the most frequently asked questions, organized by
functional area.
Multiple SSIDs
Q. What Are BSSIDs and SSIDs?
A. BSSID (Basic Service Set Identifier) refers to an individual access point
radio and its associated clients. The identifier is the MAC address of the
access point radio that forms the BSS.
A group of BSSs can be formed to allow stations in one BSS to
communicate to stations in another BSS by way of a backbone that
interconnects each access point.
The Extended Service Set (ESS) refers to the group of BSSIDs that are
grouped together to form one ESS. The ESSID (often referred to as SSID or
“wireless network name”) identifies the Extended Service Set. Clients
must associate to a single ESS at any given time. Clients ignore traffic
from other Extended Service Sets that do not have the same SSID.
Legacy access points typically support one SSID per access point. Xirrus
Wi-Fi Arrays support the ability for multiple SSIDs to be defined and
used simultaneously.
334
Appendix C: Technical Support
Wi-Fi Array
Q. What would I use SSIDs for?
A. The creation of different wireless network names allows system
administrators to separate types of users with different requirements. The
following policies can be tied to an SSID:
Minimum security required to join this SSID.
The wireless Quality of Service (QoS) desired for this SSID.
The wired VLAN associated with this SSID.
As an example, one SSID named accounting might require the highest
level of security, while another SSID named guests might have low
security requirements.
Another example may define an SSID named voice that supports voice
over Wireless LAN phones with the highest possible Quality of Service
(QoS) definition. This type of SSID might also forward traffic to specific
VLANs on the wired network.
Q. How do I set up SSIDs?
A. Use the following procedure as a guideline. For more detailed
information, go to “SSIDs” on page 184.
1.
From the Web Management Interface, go to the SSID
Management page.
2.
Select Yes to make the SSID visible to all clients on the network.
Although the Wi-Fi Array will not broadcast SSIDs that are
hidden, clients can still associate to a hidden SSID if they know
the SSID name to connect to it.
3.
Select the minimum security that will be required by users for
this SSID.
4.
If desired (optional), select a Quality of Service (QoS) setting for
this SSID. The QoS setting you define here will prioritize wireless
traffic for this SSID over other SSID wireless traffic.
5.
If desired (optional), select a VLAN that you want this traffic to
be forwarded to on the wired network.
Appendix C: Technical Support
335
Wi-Fi Array
6.
If desired (optional), you can select which radios this SSID will
not be available on—the default is to make this SSID available on
all radios.
7.
Click on the Apply button to apply your changes to this session.
8.
Click on the Save button to save your changes.
9.
If you need to edit any of the SSID settings, you can do so from

Security
Q. How do I know my management session is secure?
A. Follow these guidelines:
336
Administrator passwords
Always change the default administrator password (the default
is admin), and choose a strong replacement password. When
appropriate, issue read only administrator accounts.
SSH versus Telnet
Be aware that Telnet is not secure over network connections and
should be used only with a direct serial port connection. When
connecting to the unit’s Command Line Interface over a network
connection, you must use a Secure SHell (SSH) utility. The most
commonly used freeware providing SSH tools is PuTTY.
Configuration auditing
Appendix C: Technical Support
Wi-Fi Array
Do not change approved configuration settings. The optional
Xirrus Management System (XMS) offers powerful management
features for small or large Wi-Fi Array deployments, and can
audit your configuration settings automatically. In addition,
using the XMS eliminates the need for an FTP server.
Q. Which wireless data encryption method should I use?
A. Wireless data encryption prevents eavesdropping on data being
transmitted or received over the airwaves. The Wi-Fi Array allows you to
establish the following data encryption configuration options:
Open
This option offers no data encryption and is not recommended,
though you might choose this option if clients are required to use
a VPN connection through a secure SSH utility, like PuTTy.
WEP (Wired Equivalent Privacy)
This option provides minimal protection (though much better
than using an open network). An early standard for wireless data
encryption and supported by all Wi-Fi certified equipment, WEP
is vulnerable to hacking and is therefore not recommended for
use by Enterprise networks.
WPA (Wi-Fi Protected Access)
This is a much stronger encryption model than WEP and uses
TKIP (Temporal Key Integrity Protocol) with AES (Advanced
Encryption Standard) to prevent WEP cracks.
TKIP solves security issues with WEP. It also allows you to
establish encryption keys on a per-user-basis, with key rotation
for added security. In addition, TKIP provides Message Integrity
Check (MIC) functionality and prevents active attacks on the
wireless network.
AES is the strongest encryption standard and is used by
government agencies; however, old legacy hardware may not be
capable of supporting the AES mode (it probably won’t work on
older wireless clients). Because AES is the strongest encryption
Appendix C: Technical Support
337
Wi-Fi Array
standard currently available, it is highly recommended for
Enterprise networks.
Any of the above encryption modes can be used (and can be used at
the same time).
Q. Which user authentication method should I use?
A. User authentication ensures that users are who they say they are. For
example, the most obvious example of authentication is logging in with a
user name and password. The Wi-Fi Array allows you to choose between
the following user authentication methods:
Pre-Shared Key
Users must manually enter a key (pass phrase) on the client side
of the wireless network that matches the key stored by the
administrator in your Wi-Fi Arrays.
RADIUS 802.1x with EAP
802.1x uses a RADIUS server to authenticate large numbers of
clients, and can handle different EAP (Extensible Authentication
Protocol) authentication methods, including EAP-TLS, EAPTTLS and EAP-PEAP. The RADIUS server can be internal
(provided by the Wi-Fi Array) or external. An external RADIUS
server offers more functionality and is recommended for large
Enterprise deployments.
When using this method, user names and passwords must be
entered into the RADIUS server for user authentication.
MAC Address ACLs (Access Control Lists)
MAC address ACLs provide a list of client adapter MAC
addresses that are allowed or denied access to the wireless
network. Access Control Lists work well when there are a limited
number of users—in this case, enter the MAC addresses of each
user in the Allow list. In the event of a lost or stolen MAC
adapter, enter the affected MAC address in the Deny list.
Q. Why do I need to authenticate my Wi-Fi Array units?
338
Appendix C: Technical Support
Wi-Fi Array
A. When deploying multiple Wi-Fi Arrays, you may need to define which
units are part of which wireless network (for example, if you are
establishing more than one network). In this case, you need to employ the
Xirrus Management System (XMS) which can authenticate your Arrays
automatically and ensure that only authorized units are associated with
the defined wireless network.
Q. What is rogue AP (Access Point) detection?
A. The Wi-Fi Array has a dedicated radio (abg/4) which constantly scans the
local wireless environment for rogue APs (non-Xirrus devices that are not
part of your wireless network), unencrypted transmissions, and other
security issues. Administrators can then classify each rogue AP and
ensure that these devices do not interrupt or interfere with the network.

VLAN Support
Q. What Are VLANs?
A. VLANs (Virtual Local Area Networks) are a logical grouping of network
devices that share a common network broadcast domain. Members of a
particular VLAN can be on any segment of the physical network but
logically only members of a particular VLAN can see each other.
VLANs are defined and implemented using the wired network switches
that are VLAN capable. Packets are tagged for transmission on a
particular VLAN according to the IEEE 802.1Q standard, with VLAN
switches processing packets according to the tag.
Q. What would I use VLANs for?
Appendix C: Technical Support
339
Wi-Fi Array
A. Logically separating different types of users, systems, applications, or
other logical division aids in performance and management of different
network devices. Different VLANs can also be assigned with different
packet priorities to prioritize packets from one VLAN over packets from
another VLAN.
VLANs are managed by software settings—instead of physically
plugging in and moving network cables and users—which helps to ease
network management tasks.
Q. What are Wireless VLANs?
A. Wireless VLANs allow similar functionality to the wired VLAN
definitions and extend the operation of wired VLANs to the wireless side
of the network.
Wireless VLANs can be mapped to wireless SSIDs so that traffic from
wired VLANs can be sent to wireless users of a particular SSID. The
reverse is also true, where wireless traffic originating from a particular
SSID can be tagged for transmission on a particular wired VLAN.
Sixteen SSIDs can be defined on your Wi-Fi Array, allowing a total of
sixteen VLANs to be accessed (one per SSID).
As an example, to provide guest user access an SSID of guest might be
created. This SSID could be mapped to a wired VLAN that segregates
unknown users from the rest of the wired network and restricts them to
Internet access only. Wireless users could then associate to the wireless
network via the guest SSID and obtain access to the Internet through the
selected VLAN, but would be able to access other privileged network
resources.

Array Monitor and Loopback Testing Capabilities
All models of the Wi-Fi Array have a monitor radio, abg2, that checks that the
Array’s radios are functioning correctly, and acts as a dedicated threat sensor to
detect and prevent intrusion from rogue access points.
Enabling Monitoring on the Array
IAP abg2 may be set to monitor the Array or to be a normal IAP radio. In order to
enable the functions required for intrusion detection and for monitoring the other
Array radios, you must configure abg2 on the IAP Settings window as follows:
Check the Enabled checkbox.
Set Mode to Monitor.
Set Channel to Monitor.
The settings above will automatically set the Antenna selection to
Internal-Omni., also required for monitoring. See the “IAP Settings” on page 204
for more details. The values above are the factory default settings for the Array.
How Monitoring Works
When the monitor radio abg2 has been configured as just described, it performs
these steps continuously (24/7) to check the other radios on the Array and detect
possible intrusions:
1.
The monitor radio scans all channels with a 200ms dwell time, hitting all
channels about once every 10 seconds.
2.
Each time it tunes to a new channel it sends out a probe request in an
attempt to smoke out rogues.
3.
It then listens for all probe responses and beacons to detect any rogues
within earshot.
4.
Array radios respond to that probe request with a probe response.
Intrusion Detection is enabled or disabled separately from monitoring. See Step 1
in “Advanced RF Settings” on page 221. Note that the Advanced setting is only
used with the optional Xirrus Defense Module (XDM) software package.
Appendix C: Technical Support
341
Wi-Fi Array
Loopback Testing
The Array is capable of performing continuous, comprehensive tests on its radios
to assure that they are operating properly. Testing is enabled using the Radio
Assurance Mode setting on the Advanced RF Settings window (Step 5 in
“Advanced RF Settings” on page 221). When this mode is enabled, IAP abg2
performs loopback tests on the Array. Radio Assurance Mode (also called
loopback mode) requires Intrusion Detection to be set to Standard (See Step 1 in
“Advanced RF Settings” on page 221).
When Loopback Mode is enabled:
342
1.
The Array keeps track of whether or not it hears beacons and probe
responses from the Array’s radios.
2.
After 10 minutes (roughly 60 passes on a particular channel by the
monitor radio), if it has not heard beacons or probe responses from one of
the Array’s radios it issues an alert in the Syslog. If repair is allowed (see
“Loopback Mode Options” on page 343), the Array will reset and
reprogram that particular radio at the Physical Layer (PHY—Layer 1).
This action takes under 100ms and stations are not deauthenticated, thus
users should not be impacted.
3.
After another 10 minutes (roughly another 60 passes), if the monitor still
has not heard beacons or probe responses from the malfunctioning radio
it will again issue an alert in the Syslog. If repair is allowed, the Array will
reset and reprogram the MAC (the lower sublayer of the Data Link Layer)
and then all of the PHYs. This is a global action that affects all radios. This
action takes roughly 300ms and stations are not deauthenticated, thus
users should not be impacted.
4.
After another 10 minutes, if the monitor still has not heard beacons or
probe responses from that radio, it will again syslog the issue. If reboot is
allowed (see “Loopback Mode Options” on page 343), the Array will
schedule a reboot. This reboot will occur at one of the following times,
whichever occurs first:
•
When no stations are associated to the Array
•
Midnight
Appendix C: Technical Support
Wi-Fi Array
Loopback Mode Options
If the monitor detects a problem with an Array radio as described above, it will
take action according to the preference that you have specified in the Radio
Assurance Mode setting on the Advanced RF Settings window (see Step 5
page 223):
Failure alerts only—The Array will issue alerts in the Syslog, but will not
initiate repairs or reboots.
Failure alerts & repairs, but no reboots—The Array will issue alerts and
perform resets of the PHY and MAC as described above.
Failure alerts & repairs & reboots if needed—The Array will issue alerts,
perform resets of the PHY and MAC, and schedule reboots as described
above.
Disabled—Disable IAP loopback tests (no self-monitoring occurs).
Loopback tests are disabled by default.

Upgrading the Array via CLI
If you are experiencing difficulties communicating with the Array using the Web
Management Interface, the Array provides lower-level facilities that may be used
to accomplish an upgrade via the CLI and the Xirrus Boot Loader (XBL).
1.
Download the latest software update from the Xirrus FTP site using your
Enhanced Care FTP username and password. If you do not have an FTP
username and password, contact Xirrus Customer Service for assistance
(support@xirrus.com). The software update is provided as a zip file.
Unzip the contents to a local temp directory. Take note of the extracted file
name in case you need it later on—you may also need to copy this file
elsewhere on the network depending on your situation.
2.
Install a TFTP server software package if you don't have one running. It
may be installed on any PC on your network, including your desktop or
laptop. The Solar Winds version is freeware and works well.
http://support.solarwinds.net/updates/New-customerFree.cfm?ProdId=52
The TFTP install process creates the TFTP-Root directory on your C:
drive, which is the default target for sending and receiving files. This may
be changed if desired. This directory is where you will place the extracted
Xirrus software update file(s). If you install the TFTP server on the same
computer to which you extracted the file, you may change the TFTP
directory to C:\xirrus if desired.
You must make the following change to the default configuration of the
Solar Winds TFTP server. In the File/Configure menu, select Security,
then select Transmit only and click OK.
344
3.
Determine the IP address of the computer hosting the TFTP server. (To
display the IP address, open a command prompt and type ipconfig)
4.
Connect your Array to the computer running TFTP using a serial cable,
and open a terminal program if you haven't already. Attach a network
cable to the Array’s GIG1 port, if it is not already part of your network.

Glossary of Terms
802.11a
A supplement to the IEEE 802.11 WLAN specification that describes radio
transmissions at a frequency of 5 GHz and data rates of up to 54 Mbps.
802.11b
A supplement to the IEEE 802.11 WLAN specification that describes radio
transmissions at a frequency of 2.4 GHz and data rates of up to 11 Mbps.
802.11d
A supplement to the Media Access Control (MAC) layer in 802.11 to promote
worldwide use of 802.11 WLANs. It allows Access Points to communicate
information on the permissible radio channels with acceptable power levels for
user devices. Because the 802.11 standards cannot legally operate in some
countries, 802.11d adds features and restrictions to allow WLANs to operate
within the rules of these countries.
802.11g
A supplement to the IEEE 802.11 WLAN specification that describes radio
transmissions at a frequency of 2.4 GHz and data rates of up to 54 Mbps.
802.1Q
An IEEE standard for MAC layer frame tagging (also known as encapsulation).
Frame tagging uniquely assigns a user-defined ID to each frame. It also enables a
switch to communicate VLAN membership information across multiple (and
multi-vendor) devices by frame tagging.
AES
(Advanced Encryption Standard) A data encryption scheme that uses three
different key sizes (128-bit, 192-bit, and 256-bit). AES was adopted by the U.S.
government in 2002 as the encryption standard for protecting sensitive but
unclassified electronic data.
Glossary of Terms

Wi-Fi Array
authentication
The process that a station, device, or user employs to announce its identify to
the network which validates it. IEEE 802.11 specifies two forms of authentication,
open system and shared key.
bandwidth
Specifies the amount of the frequency spectrum that is usable for data transfer. In
other words, it identifies the maximum data rate a signal can attain on
the medium without encountering significant attenuation (loss of power).
beacon interval
When a device in a wireless network sends a beacon, it includes with it a beacon
interval, which specifies the period of time before it will send the beacon again.
The interval tells receiving devices on the network how long they can wait in low
power mode before waking up to handle the beacon. Network administrators can
adjust the beacon interval—usually measured in milliseconds (ms) or its
equivalent, kilo-microseconds (Kmsec).
bit rate
The transmission rate of binary symbols ('0' and '1'), equal to the total number of
bits transmitted in one second.
BSS
(Basic Service Set) When a WLAN is operating in infrastructure mode, each access
point and its connected devices are called the Basic Service Set.
BSSID
The unique identifier for an access point in a BSS network. See also, SSID.
CDP
(Cisco Discovery Protocol) CDP is a layer 2 network protocol which runs on most
Cisco equipment and some other network equipment. It is used to share
information with other directly connected network devices. Information such as
the model, network capabilities, and IP address is shared. Wi-Fi Arrays can both
advertise their presence by sending CDP announcements, and gather and display
information sent by neighbors.
352
Glossary of Terms
Wi-Fi Array
cell
The basic geographical unit of a cellular communications system. Service
coverage of a given area is based on an interlocking network of cells, each with a
radio base station (transmitter/receiver) at its center. The size of each cell is
determined by the terrain and forecasted number of users.
channel
A specific portion of the radio spectrum—the channels allotted to one of
the wireless networking protocols. For example, 802.11b and 802.11g use 14
channels in the 2.4 GHz band, only 3 of which don't overlap (1, 6, and 11). In the 5
GHz band, 802.11a uses 8 channels for indoor use and 4 for outdoor use, none of
which overlap. In the U.S., additional channels are available, to bring the total to
24 channels.
CoS
(Class of Service) A category based on the type of user, type of application,
or some other criteria that QoS systems can use to provide differentiated classes of
service.
default gateway
The gateway in a network that a computer will use to access another network if
a gateway is not specified for use. In a network using subnets, a default gateway
is the router that forwards traffic to a destination outside of the subnet of
the transmitting device.
DHCP
(Dynamic Host Configuration Protocol) A method for dynamically assigning IP
addresses to devices on a network. DHCP issues IP addresses automatically
within a specified range to client devices when they are first powered up.
DHCP lease
The DHCP lease is the amount of time that the DHCP server grants to the DHCP
client for permission to use a particular IP address. A typical DHCP server allows
its administrator to set the lease time.
Glossary of Terms
353
Wi-Fi Array
DNS
(Domain Name System) A system that maps meaningful domain names with
complex numeric IP addresses. DNS is actually a separate network—if one DNS
server cannot translate a domain name, it will ask a second or third until a server
is found with the correct IP address.
domain
The main name/Internet address of a user's Internet site as registered with
the InterNIC organization, which handles domain registration on the Internet. For
example, the “domain” address for Xirrus is: http://www.xirrus.com, broken
down as follows:
z http:// represents the Hyper Text Teleprocessing Protocol used by all Web
pages.
www is a reference to the World Wide Web.
xirrus refers to the company.
com specifies that the domain belongs to a commercial enterprise.
DTIM
(Delivery Traffic Indication Message) A DTIM is a signal sent as part of a beacon
by an access point to a client device in sleep mode, alerting the device to a packet
awaiting delivery.
EAP
(Extensible Authentication Protocol) When you log on to the Internet, you're most
likely establishing a PPP connection via a remote access server. The password,
key, or other device you use to prove that you are authorized to do so is controlled
via PPP’s Link Control Protocol (LCP). However, LCP is somewhat inflexible
because it has to specify an authentication device early in the process. EAP allows
the system to gather more information from the user before deciding which
authenticator to use. It is called extensible because it allows more authenticator
types than LCP (for example, passwords and public keys).
354
Glossary of Terms
Wi-Fi Array
EDCF
(Enhanced Distributed Coordinator Function) A QoS extension which uses
the same contention-based access mechanism as current devices but adds “offset
contention windows” that separate high priority packets from low priority
packets (by assigning a larger random backoff window to lower priorities than to
higher priorities). The result is “statistical priority,” where high-priority packets
usually are transmitted before low-priority packets.
encapsulation
A way of wrapping protocols such as TCP/IP, AppleTalk, and NetBEUI in
Ethernet frames so they can traverse an Ethernet network and be unwrapped
when they reach the destination computer.
encryption
Any procedure used in cryptography to translate data into a form that can be
decrypted and read only by its intended receiver.
Fast Ethernet
A version of standard Ethernet that runs at 100 Mbps rather than 10 Mbps.
FCC
(Federal Communications Commission) US wireless regulatory authority.
The FCC was established by the Communications Act of 1934 and is charged with
regulating Interstate and International communications by radio, television, wire,
satellite and cable.
frame
A packet encapsulated to travel on a physical medium, like Ethernet or Wi-Fi. If a
packet is like a shipping container, a frame is the boat on which the shipping
container is loaded.
Gigabit 1
The primary Gigabit Ethernet interface. See also, Gigabit Ethernet.
Gigabit 2
The secondary Gigabit Ethernet interface. See also, Gigabit Ethernet.
Gigabit Ethernet
The newest version of Ethernet, with data transfer rates of 1 Gigabit (1,000 Mbps).
Glossary of Terms

Wi-Fi Array
Group
A user group, created to define a set of attributes (such as VLAN, traffic limits,
and Web Page Redirect) and privileges (such as fast roaming) that apply to all
users that are members of the group. This allows a uniform configuration to be
easily applied to multiple user accounts. The attributes that can be configured for
user groups are almost identical to those that can be configured for SSIDs.
host name
The unique name that identifies a computer on a network. On the Internet,
the host name is in the form comp.xyz.net. If there is only one Internet site
the host name is the same as the domain name. One computer can have more than
one host name if it hosts more than one Internet site (for example, home.xyz.net
and comp.xyz.net). In this case, comp and home are the host names and xyz.net is
the domain name.
IPsec
A Layer 3 authentication and encryption protocol. Used to secure VPNs.
MAC address
(Media Access Control Address) A 6-byte hexadecimal address assigned by a
manufacturer to a device.
Mbps
(Megabits per second) A standard measure for data transmission speeds (for
example, the rate at which information travels over the Internet). 1 Mbps denotes
one million bits per second.
MTU
(Maximum Transmission Unit) The largest physical packet size—measured in
bytes—that a network can transmit. Any messages larger than the MTU are
divided into smaller packets before being sent. Every network has a different
MTU, which is set by the network administrator. Ideally, you want the MTU to be
the same as the smallest MTU of all the networks between your machine and
a message's final destination. Otherwise, if your messages are larger than one of
the intervening MTUs, they will get broken up (fragmented), which slows down
transmission speeds.
356
Glossary of Terms
Wi-Fi Array
NTP
(Network Time Protocol) An Internet standard protocol (built on top of TCP/IP)
that ensures the accurate synchronization (to the millisecond) of computer clock
times in a network of computers. Running as a continuous background client
program on a computer, NTP sends periodic time requests to servers, obtaining
server time stamps and using them to adjust the client's clock.
packet
Data sent over a network is broken down into many small pieces—packets—by
the Transmission Control Protocol layer of TCP/IP. Each packet contains the
address of its destination as well the data. Packets may be sent on any number of
routes to their destination, where they are reassembled into the original data. This
system is optimal for connectionless networks, such as the Internet, where there
are no fixed connections between two locations.
PLCP
(Physical Layer Convergence Protocol) Defined by IEEE 802.6, a protocol
specified within the Transmission Convergence layer that defines exactly how
cells are formatted within a data stream for a particular type of transmission
facility.
PoGE
This refers to the optional Xirrus XP1 Power over Gigabit Ethernet modules that
provide DC power to Arrays. Power is supplied over the same Cat 5e or Cat 6
cable that supplies the data connection to your gigabit Ethernet switch, thus
eliminating the need to run a power cable. See “Contact Information” on page 349
for a list of Xirrus PoGE modules and the modules that are compatible with each
Array.
preamble
Preamble (sometimes called a header) is a section of data at the head of a packet
that contains information that the access point and client devices need when
sending and receiving packets. PLCP has two structures, a long and a short
preamble. All compliant 802.11b systems have to support the long preamble.
The short preamble option is provided in the standard to improve the efficiency
of a network's throughput when transmitting special data, such as voice, VoIP
(Voice-over IP) and streaming video.
Glossary of Terms

Wi-Fi Array
private key
In cryptography, one of a pair of keys (one public and one private) that are created
with the same algorithm for encrypting and decrypting messages and digital
signatures. The private key is provided only to the requestor and never shared.
The requestor uses the private key to decrypt text that has been encrypted with
the public key by someone else.
PSK
(Pre-Shared Key) A TKIP passphrase used to protect your network traffic in WPA.
public key
In cryptography, one of a pair of keys (one public and one private) that are created
with the same algorithm for encrypting and decrypting messages and digital
signatures. The public key is made publicly available for encryption and
decryption.
QoS
(Quality of Service) QoS can be used to describe any number of ways in which
a network provider prioritizes or guarantees a service's performance.
RADIUS
(Remote Authentication Dial-In User Service) A client-server security protocol,
developed to authenticate, authorize, and account for dial-up users. The RADIUS
server stores user profiles, which include passwords and authorization attributes.
RSSI
(Received Signal Strength Indicator) A measure of the energy observed by an
antenna when receiving a signal.
SDMA
(Spatial Division Multiple Access) A wireless communications mode that
optimizes the use of the radio spectrum and minimizes cost by taking advantage
of the directional properties of antennas. The antennas are highly directional,
allowing duplicate frequencies to be used for multiple zones.
SNMP
(Simple Network Management Protocol) A standard protocol that regulates
network management over the Internet.
358
Glossary of Terms
Wi-Fi Array
SNTP
(Simple Network Time Protocol) A simplified version of NTP. SNTP can be used
when the ultimate performance of the full NTP implementation described in RFC
1305 is not needed or justified.
SSH
(Secure SHell) Developed by SSH Communications Security, Secure Shell is a
program to log into another computer over a network, to execute commands in a
remote machine, and to move files from one machine to another. It provides
strong authentication and secure communications over insecure channels. SSH
protects a network from attacks, such as IP spoofing, IP source routing, and DNS
spoofing. Attackers who has managed to take over a network can only force SSH
to disconnect—they cannot “play back” the traffic or hijack the connection when
encryption is enabled. When using SSH's slogin (instead of rlogin) the entire login
session, including transmission of password, is encrypted making it almost
impossible for an outsider to collect passwords.
SSID
(Service Set IDentifier) Every wireless network or network subset (such as a BSS)
has a unique identifier called an SSID. Every device connected to that part of the
network uses the same SSID to identify itself as part of the family—when it wants
to gain access to the network or verify the origin of a data packet it is sending over
the network. In short, it is the unique name shared among all devices in a WLAN.
subnet mask
A mask used to determine what subnet an IP address belongs to. An IP address
has two components: (1) the network address and (2) the host address. For
example, consider the IP address 150.215.017.009. Assuming this is part of a Class
B network, the first two numbers (150.215) represent the Class B network address,
and the second two numbers (017.009) identify a particular host on this network.
TKIP
(Temporal Key Integrity Protocol) Provides improved data encryption by
scrambling the keys using a hashing algorithm and, by adding an integritychecking feature, ensures that the encryption keys haven’t been tampered with.
transmit power
The amount of power used by a radio transceiver to send the signal out. Transmit
power is generally measured in milliwatts, which you can convert to dBm.
Glossary of Terms

User group
See Group.
VLAN
(Virtual LAN) A group of devices that communicate as a single network, even
though they are physically located on different LAN segments. Because VLANs
are based on logical rather than physical connections, they are extremely flexible.
A device that is moved to another location can remain on the same VLAN
without any hardware reconfiguration.
VLAN tagging
(Virtual LAN tagging) Static port-based VLANs were originally the only way to
segment a network without using routing, but these port-based VLANs could
only be implemented on a single switch (or switches) cabled together. Routing
was required to transfer traffic between unconnected switches. As an alternative
to routing, some vendors created proprietary schemes for sharing VLAN
information across switches. These methods would only operate on that vendor's
equipment and were not an acceptable way to implement VLANs. With the
adoption of the 802.1Q standard, traffic can be confined to VLANs that exist on
multiple switches from different vendors. This interoperability and traffic
containment across different switches is the result of a switch's ability to use and
recognize 802.1Q tag headers—called VLAN tagging. Switches that implement
802.1Q tagging add this tag header to the frame directly after the destination and
source MAC addresses. The tag header indicates:
1. That the packet has a tag.
2.
Whether the packet should have priority over other packets.
3.
Which VLAN it belongs to, so that the switch can forward or filter it
correctly.
WDS (Wireless Distribution System)
WDS creates wireless backhauls between arrays. These links between arrays may
be used rather than having to install data cabling to each array.
WEP
(Wired Equivalent Privacy) An optional IEEE 802.11 function that offers frame
transmission privacy similar to a wired network. The Wired Equivalent Privacy
generates secret shared encryption keys that both source and destination stations
can use to alter frame bits to avoid disclosure to eavesdroppers.

goal of the Wi-Fi Alliance's members is to enhance the user experience through
product interoperability.
Wi-Fi Array
A high capacity Wi-Fi networking device consisting of multiple radios arranged

WPA
(Wi-Fi Protected Access) A Wi-Fi Alliance standard that contains a subset of the
IEEE 802.11i standard, using TKIP as an encryption method and 802.1x for
authentication.
WPA2
(Wi-Fi Protected Access 2) WPA2 is the follow-on security method to WPA for
wireless networks and provides stronger data protection and network access
control. It offers Enterprise and consumer Wi-Fi users with a high level of
assurance that only authorized users can access their wireless networks. Like
WPA, WPA2 is designed to secure all versions of 802.11 devices, including
802.11a, 802.11b, 802.11g, and 802.11n, multi-band and multi-mode.
