Wi-Fi ArrayThe Command Line Interface 291Sample Configuration TasksThis section provides examples of some of the common configuration tasks used with the Wi-Fi Array, including:z“Configuring a Simple Open Global SSID” on page 292.z“Configuring a Global SSID using WPA-PEAP” on page 293.z“Configuring an SSID-Specific SSID using WPA-PEAP” on page 294.z“Enabling Global IAPs” on page 295.z“Disabling Global IAPs” on page 296.z“Enabling a Specific IAP” on page 297.z“Disabling a Specific IAP” on page 298.z“Setting Cell Size Auto-Configuration for All IAPs” on page 299z“Setting the Cell Size for All IAPs” on page 300.z“Setting the Cell Size for a Specific IAP” on page 301.z“Configuring VLANs on an Open SSID” on page 302.z“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.
Wi-Fi Array292 The Command Line InterfaceConfiguring a Simple Open Global SSIDThis example shows you how to configure a simple open global SSID.Figure 142. Configuring a Simple Open Global SSID
Wi-Fi ArrayThe Command Line Interface 293Configuring a Global SSID using WPA-PEAPThis example shows you how to configure a global SSID using WPA-PEAP encryption in conjunction with the Array’s Internal RADIUS server.Figure 143. Configuring a Global SSID using WPA-PEAP
Wi-Fi Array294 The Command Line InterfaceConfiguring an SSID-Specific SSID using WPA-PEAPThis example shows you how to configure an SSID-specific SSID using WPA-PEAP encryption in conjunction with the Array’s Internal RADIUS server.Figure 144. Configuring an SSID-Specific SSID using WPA-PEAP
Wi-Fi ArrayThe Command Line Interface 295Enabling Global IAPsThis example shows you how to enable all IAPs (radios), regardless of the wireless technology they use.Figure 145. Enabling Global IAPs
Wi-Fi Array296 The Command Line InterfaceDisabling Global IAPsThis example shows you how to disable all IAPs (radios), regardless of the wireless technology they use.Figure 146. Disabling Global IAPs
Wi-Fi ArrayThe Command Line Interface 297Enabling a Specific IAPThis example shows you how to enable a specific IAP (radio). In this example, the IAP that is being enabled is a1 (the first IAP in the summary list).Figure 147. Enabling a Specific IAP
Wi-Fi Array298 The Command Line InterfaceDisabling a Specific IAPThis example shows you how to disable a specific IAP (radio). In this example, the IAP that is being disabled is a2 (the second IAP in the summary list).Figure 148. Disabling a Specific IAP
Wi-Fi ArrayThe Command Line Interface 299Setting Cell Size Auto-Configuration for All IAPsThis example shows how to set the cell size for all enabled IAPs to be auto-configured (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 auto-configuration 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. Figure 149. Setting the Cell Size for All IAPs
Wi-Fi Array300 The Command Line InterfaceSetting the Cell Size for All IAPsThis 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.Figure 150. Setting the Cell Size for All IAPs
Wi-Fi ArrayThe Command Line Interface 301Setting the Cell Size for a Specific IAPThis example shows you how to establish the cell size for a specific IAP (radio). In this example, the cell size for a2 is being set to medium. You have the option of setting IAP cell sizes to small, medium, large, or max (the default is max). See also, “Fine Tuning Cell Sizes” on page 35.Figure 151. Setting the Cell Size for a Specific IAP
Wi-Fi Array302 The Command Line InterfaceConfiguring VLANs on an Open SSIDThis example shows you how to configure VLANs on an Open SSID.Figure 152. Configuring VLANs on an Open SSID#Setting the default route enables the Array to send management traffic, such as syslog messages and SNMP information to a destination behind a router.
Wi-Fi ArrayThe Command Line Interface 303Configuring 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: zalert-only—the Array will issue an alert in the Syslog. zrepair-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. zreboot-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. zoff—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. Self-monitoring mode requires Intrusion Detection to be set to Standard.The following example shows you how to configure a loopback test.

Wi-Fi ArrayAppendix C: Technical Support 333Appendix C: Technical SupportThis 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:z“General Hints and Tips” on page 333z“Frequently Asked Questions” on page 334z“Array Monitor and Loopback Testing Capabilities” on page 341z“Upgrading the Array via CLI” on page 344z“Contact Information” on page 349z“Contact Information” on page 349General Hints and TipsThis section provides some useful tips that will optimize the reliability and performance of your Wi-Fi Arrays.zThe Wi-Fi Array requires careful handling. For best performance, units should be mounted in a dust-free and temperature-controlled environment.zIf 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.zKeep 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).zIf 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.
Wi-Fi Array334 Appendix C: Technical SupportzIf 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.zThe Wi-Fi Array should only be used with Wi-Fi certified client devices.See AlsoContact InformationMultiple SSIDsSecurityVLAN SupportFrequently Asked QuestionsThis section answers some of the most frequently asked questions, organized by functional area.Multiple SSIDsQ. 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.
Wi-Fi ArrayAppendix C: Technical Support 335Q. 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:zMinimum security required to join this SSID.zThe wireless Quality of Service (QoS) desired for this SSID.zThe 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.
Wi-Fi Array336 Appendix C: Technical Support6. 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 the SSID Management page.See AlsoContact InformationGeneral Hints and TipsSecuritySSIDsSSID ManagementVLAN SupportSecurityQ. How do I know my management session is secure?A. Follow these guidelines:zAdministrator passwordsAlways change the default administrator password (the default is admin), and choose a strong replacement password. When appropriate, issue read only administrator accounts.zSSH versus TelnetBe 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.zConfiguration auditing
Wi-Fi ArrayAppendix C: Technical Support 337Do 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:zOpenThis 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.zWEP (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.zWPA (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
Wi-Fi Array338 Appendix C: Technical Supportstandard 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:zPre-Shared KeyUsers 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.zRADIUS 802.1x with EAP802.1x uses a RADIUS server to authenticate large numbers of clients, and can handle different EAP (Extensible Authentication Protocol) authentication methods, including EAP-TLS, EAP-TTLS 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.zMAC 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?
Wi-Fi ArrayAppendix C: Technical Support 339A. 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.See AlsoContact InformationGeneral Hints and TipsMultiple SSIDsVLAN SupportVLAN SupportQ. 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?
Wi-Fi Array340 Appendix C: Technical SupportA. 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.See AlsoContact InformationGeneral Hints and TipsMultiple SSIDsSecurity
Wi-Fi ArrayAppendix C: Technical Support 341Array Monitor and Loopback Testing CapabilitiesAll 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 ArrayIAP 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:zCheck the Enabled checkbox.zSet Mode to Monitor.zSet 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 204for more details. The values above are the factory default settings for the Array. How Monitoring WorksWhen 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 1in “Advanced RF Settings” on page 221. Note that the Advanced setting is only used with the optional Xirrus Defense Module (XDM) software package.
Wi-Fi Array342 Appendix C: Technical SupportLoopback TestingThe 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: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
Wi-Fi ArrayAppendix C: Technical Support 343Loopback Mode OptionsIf 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 5page 223):zFailure alerts only—The Array will issue alerts in the Syslog, but will not initiate repairs or reboots.zFailure alerts & repairs, but no reboots—The Array will issue alerts and perform resets of the PHY and MAC as described above. zFailure alerts & repairs & reboots if needed—The Array will issue alerts, perform resets of the PHY and MAC, and schedule reboots as described above. zDisabled—Disable IAP loopback tests (no self-monitoring occurs). Loopback tests are disabled by default.
Wi-Fi Array344 Appendix C: Technical SupportUpgrading the Array via CLIIf 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=52The 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 Tra nsmi t o nly and click OK.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.
Wi-Fi ArrayAppendix C: Technical Support 345Boot your Array and watch the progress messages. When Press space bar to exit to bootloader: is displayed, press the space bar. The rest of this procedure is performed using the bootloader. The following steps assume that you are running DHCP on your local network. 5. Type dhcp and hit return. This instructs the Array to obtain a DHCP address and use it during this boot in the bootloader environment. 6. Type dir and hit return to see what's currently in the compact flash. 7. Type del and hit return to delete the contents of the compact flash. 8. Type update server <TFTP-server-ip-addr> xs-3.x-xxxx.bin (the actual Xirrus file name will vary depending on Array model number and software version—use the file name from your software update) and hit return. The software update will be transferred to the Array's memory and will be written to the it’s compact flash card. (See output below.)9. Type reset and hit return. Your Array will reboot, running your new version of software.

Wi-Fi ArrayGlossary of Terms 351Glossary of Terms802.11aA 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.802.11bA 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.802.11dA 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.802.11gA 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.802.1QAn 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.
Wi-Fi Array352 Glossary of TermsauthenticationThe 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.bandwidthSpecifies 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 intervalWhen 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 rateThe 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.BSSIDThe 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.
Wi-Fi ArrayGlossary of Terms 353cellThe 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.channelA 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 gatewayThe 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 leaseThe 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.
Wi-Fi Array354 Glossary of TermsDNS(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.domainThe 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:zhttp:// represents the Hyper Text Teleprocessing Protocol used by all Web pages.zwww is a reference to the World Wide Web.zxirrus refers to the company.zcom 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).
Wi-Fi ArrayGlossary of Terms 355EDCF(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.encapsulationA 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.encryptionAny procedure used in cryptography to translate data into a form that can be decrypted and read only by its intended receiver.Fast EthernetA 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.frameA 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 1The primary Gigabit Ethernet interface. See also, Gigabit Ethernet.Gigabit 2The secondary Gigabit Ethernet interface. See also, Gigabit Ethernet.Gigabit EthernetThe newest version of Ethernet, with data transfer rates of 1 Gigabit (1,000 Mbps).
Wi-Fi Array356 Glossary of TermsGroupA 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 nameThe 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.netand comp.xyz.net). In this case, comp and home are the host names and xyz.net is the domain name.IPsecA 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.
Wi-Fi ArrayGlossary of Terms 357NTP(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.packetData 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 349for a list of Xirrus PoGE modules and the modules that are compatible with each Array. preamblePreamble (sometimes called a header) is a section of data at the head of a packetthat 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.
Wi-Fi Array358 Glossary of Termsprivate keyIn 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 keyIn 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.
Wi-Fi ArrayGlossary of Terms 359SNTP(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 maskA 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 integrity-checking feature, ensures that the encryption keys haven’t been tampered with.transmit powerThe 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.
Wi-Fi Array360 Glossary of TermsUser groupSee 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.
Wi-Fi ArrayGlossary of Terms 361Wi-Fi AllianceA nonprofit international association formed in 1999 to certify interoperability of wireless Local Area Network products based on IEEE 802.11 specification. The goal of the Wi-Fi Alliance's members is to enhance the user experience through product interoperability.Wi-Fi ArrayA high capacity Wi-Fi networking device consisting of multiple radios arranged in a circular array.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.Xirrus Management System (XMS)A Xirrus product used for managing large Wi-Fi Array deployments from a centralized Web-based interface.XP1 and XP8—Power over Gigabit Ethernet modulesSee PoGE.XPS—Xirrus Power System A family of optional Xirrus products that provides power over Gigabit Ethernet.See PoGE.
