Wi-Fi Array356 The Command Line InterfaceSample Configuration TasksThis section provides examples of some of the common configuration tasks usedwith the Wi-Fi Array, including:z“Configuring a Simple Open Global SSID” on page 357.z“Configuring a Global SSID using WPA-PEAP” on page 358.z“Configuring an SSID-Specific SSID using WPA-PEAP” on page 359.z“Enabling Global IAPs” on page 360.z“Disabling Global IAPs” on page 361.z“Enabling a Specific IAP” on page 362.z“Disabling a Specific IAP” on page 363.z“Setting Cell Size Auto-Configuration for All IAPs” on page 364z“Setting the Cell Size for All IAPs” on page 365.z“Setting the Cell Size for a Specific IAP” on page 366.z“Configuring VLANs on an Open SSID” on page 367.z“Configuring Radio Assurance Mode (Loopback Tests)” on page 368.To facilitate the accurate and timely management of revisions to this section, theexamples shown here are presented as screen images taken from a Secure Shell(SSH) session (in this case, PuTTY). Depending on the application you are usingto access the Command Line Interface, and how your session is set up (forexample, font and screen size), the images presented on your screen may bedifferent than the images shown in this section. However, the data displayed willbe 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 theneed for additional images or scrolling. We recommend that you use the AdobePDF version of this User’s Guide when reviewing these examples—a hard copydocument may be difficult to read.As mentioned previously, the root command prompt is determined by the hostname assigned to your Array.

Wi-Fi Array358 The Command Line InterfaceConfiguring a Global SSID using WPA-PEAPThis example shows you how to configure a global SSID using WPA-PEAPencryption in conjunction with the Array’s Internal RADIUS server.Figure 164. Configuring a Global SSID using WPA-PEAP
Wi-Fi ArrayThe Command Line Interface 359Configuring 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 165. Configuring an SSID-Specific SSID using WPA-PEAP
Wi-Fi Array360 The Command Line InterfaceEnabling Global IAPsThis example shows you how to enable all IAPs (radios), regardless of thewireless technology they use.Figure 166. Enabling Global IAPs
Wi-Fi ArrayThe Command Line Interface 361Disabling Global IAPsThis example shows you how to disable all IAPs (radios), regardless of thewireless technology they use.Figure 167. Disabling Global IAPs
Wi-Fi Array362 The Command Line InterfaceEnabling a Specific IAPThis example shows you how to enable a specific IAP (radio). In this example, theIAP that is being enabled is a1 (the first IAP in the summary list).Figure 168. Enabling a Specific IAP
Wi-Fi ArrayThe Command Line Interface 363Disabling 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 169. Disabling a Specific IAP
Wi-Fi Array364 The Command Line InterfaceSetting 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 53.) The auto_cell optionmay be used with global_settings, global_a_settings, or global_bg_settings. Itsets 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 isenabled on abg(n)2, its cell size is unaffected by this command. Also, any IAPsused in WDS links are unaffected. Auto-configuration may be set to run periodically at intervals specified byauto_cell period (in seconds) if period is non-zero. The percentage of overlapallowed between cells in the cell size computation is specified by auto_celloverlap (0 to 100). This example sets auto-configuration to run every 1200 secondswith an allowed overlap of 5%. It sets the cell size of all IAPs to auto, and runs acell size auto-configure operation which completes successfully. Figure 170. Setting the Cell Size for All IAPs
Wi-Fi ArrayThe Command Line Interface 365Setting 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-detectfeature is enabled on abg(n)2 the cell size cannot be set globally—you must firstdisable the intrude-detect feature on abg(n)2.In this example, the cell size is being set to small for all IAPs. You have the optionof setting IAP cell sizes to small, medium, large, or max. See also, “Fine TuningCell Sizes” on page 53.Figure 171. Setting the Cell Size for All IAPs
Wi-Fi Array366 The Command Line InterfaceSetting the Cell Size for a Specific IAPThis example shows you how to establish the cell size for a specific IAP (radio). Inthis example, the cell size for a2 is being set to medium. You have the option ofsetting IAP cell sizes to small, medium, large, or max (the default is max). Seealso, “Fine Tuning Cell Sizes” on page 53.Figure 172. Setting the Cell Size for a Specific IAP

Configuring VLANs on an Open SSID#Setting the default routeenables the Array to sendmanagement traffic, such asSyslog messages and SNMPinformation to a destinationbehind a router.
Wi-Fi Array368 The Command Line InterfaceConfiguring Radio Assurance Mode (Loopback Tests)The Array uses the built-in monitor radio, IAP abg(n)2, to monitor other radios inthe Array. Tests include sending probes on all channels and checking for aresponse, and checking whether beacons are received from the other radio. If aproblem is detected, corrective actions are taken to recover. Loopback modeoperation is described in detail in “Array Monitor and Radio AssuranceCapabilities” on page 408. 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 atthe Physical Layer (Layer 1) and possibly at the MAC layer. The resetshould not be noticed by users, and they will not need to reassociate. zreboot-allowed—the Array will issue an alert, reset the radios, andschedule the Array to reboot at midnight (per local Array time) ifnecessary. All stations will need to reassociate to the Array. zoff—Disable IAP loopback tests (no self-monitoring occurs). RadioAssurance mode is off by default.This is a global IAPs setting—abg(n)2 will monitor all other radios according tothe settings above, and it cannot be set up to monitor particular radios. Radioassurance 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 399Appendix C: Technical SupportThis appendix provides valuable support information that can help you resolvetechnical difficulties. Before contacting Xirrus, review all topics below and try todetermine if your problem resides with the Wi-Fi Array or your networkinfrastructure. Topics include:z“General Hints and Tips” on page 399z“Frequently Asked Questions” on page 400z“Array Monitor and Radio Assurance Capabilities” on page 408z“Upgrading the Array via CLI” on page 411z“Power over Gigabit Ethernet Compatibility Matrix” on page 416z“Contact Information” on page 419General Hints and TipsThis section provides some useful tips that will optimize the reliability andperformance of your Wi-Fi Arrays.zThe Wi-Fi Array requires careful handling. For best performance, unitsshould be mounted in a dust-free and temperature-controlledenvironment.zIf using multiple Arrays in the same area, maintain a distance of at least100 feet (30m) between Arrays if there is direct line-of-sight between theunits, or at least 50 feet (15 m) if a wall or other barrier exists between theunits.zKeep the Wi-Fi Array away from electrical devices or appliances thatgenerate RF noise. Because the Array is generally mounted on ceilings, beaware of its position relative to lighting (especially fluorescent lighting).zIf using AC power, each Wi-Fi Array requires its own dedicated ACpower outlet. Do not attempt to “piggy-back” AC power to multipleunits. To avoid needing to run separate power cables to one or moreArrays, consider using Power over Gigabit Ethernet.
Wi-Fi Array400 Appendix C: Technical SupportzIf you are deploying multiple units, the Array should be oriented so thatthe abg(n)2 radio is oriented in the direction of the least requiredcoverage, because when in monitor mode the abg(n)2 radio does notfunction 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 byfunctional area.Multiple SSIDsQ. What Are BSSIDs and SSIDs?A. BSSID (Basic Service Set Identifier) refers to an individual access pointradio and its associated clients. The identifier is the MAC address of theaccess point radio that forms the BSS.A group of BSSs can be formed to allow stations in one BSS tocommunicate to stations in another BSS by way of a backbone thatinterconnects each access point.The Extended Service Set (ESS) refers to the group of BSSIDs that aregrouped together to form one ESS. The ESSID (often referred to as SSID or“wireless network name”) identifies the Extended Service Set. Clientsmust associate to a single ESS at any given time. Clients ignore trafficfrom other Extended Service Sets that do not have the same SSID.Legacy access points typically support one SSID per access point. XirrusWi-Fi Arrays support the ability for multiple SSIDs to be defined andused simultaneously.
Wi-Fi ArrayAppendix C: Technical Support 401Q. What would I use SSIDs for?A. The creation of different wireless network names allows systemadministrators to separate types of users with different requirements. Thefollowing 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 highestlevel of security, while another SSID named guests might have lowsecurity requirements.Another example may define an SSID named voice that supports voiceover Wireless LAN phones with the highest possible Quality of Service(QoS) definition. This type of SSID might also forward traffic to specificVLANs on the wired network.Q. How do I set up SSIDs?A. Use the following procedure as a guideline. For more detailedinformation, go to “SSIDs” on page 233.1. 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 Array402 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 ensure that an Array meets FIPS requirements?A. To meet the Level 2 security requirements of FIPS 140-2, follow theinstructions in Appendix D: Implementing Security Standards.Q. How do I ensure that an Array meets PCI DSS requirements?A. To meet PCI DSS requirements, follow the instructions in Appendix D:Implementing Security Standards.Q. How do I know my management session is secure?A. Follow these guidelines:zAdministrator passwordsAlways change the default administrator password (the defaultis admin), and choose a strong replacement password. Whenappropriate, issue read only administrator accounts.zSSH versus Telnet
Wi-Fi ArrayAppendix C: Technical Support 403Be aware that Telnet is not secure over network connections andshould be used only with a direct serial port connection. Whenconnecting to the unit’s Command Line Interface over a networkconnection, you must use a Secure SHell (SSH) utility. The mostcommonly used freeware providing SSH tools is PuTTY. TheArray only allows SSH-2 connections, so your SSH utility mustbe set up to use SSH-2. zConfiguration auditingDo not change approved configuration settings. The optionalXirrus Management System (XMS) offers powerful managementfeatures for small or large Wi-Fi Array deployments, and canaudit 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 beingtransmitted or received over the airwaves. The Wi-Fi Array allows you toestablish 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 usea VPN connection through a secure SSH utility, like PuTTy.zWEP (Wired Equivalent Privacy)This option provides minimal protection (though much betterthan using an open network). An early standard for wireless dataencryption and supported by all Wi-Fi certified equipment, WEPis vulnerable to hacking and is therefore not recommended foruse by Enterprise networks.zWPA (Wi-Fi Protected Access)This is a much stronger encryption model than WEP and usesTKIP (Temporal Key Integrity Protocol) with AES (AdvancedEncryption Standard) to prevent WEP cracks.
Wi-Fi Array404 Appendix C: Technical SupportTKIP solves security issues with WEP. It also allows you toestablish encryption keys on a per-user-basis, with key rotationfor added security. In addition, TKIP provides Message IntegrityCheck (MIC) functionality and prevents active attacks on thewireless network.AES is the strongest encryption standard and is used bygovernment agencies; however, old legacy hardware may not becapable of supporting the AES mode (it probably won’t work onolder wireless clients). Because AES is the strongest encryptionstandard currently available, it is highly recommended forEnterprise networks.Any of the above encryption modes can be used (and can be used atthe same time).Q. Which user authentication method should I use?A. User authentication ensures that users are who they say they are. Forexample, the most obvious example of authentication is logging in with auser name and password. The Wi-Fi Array allows you to choose betweenthe following user authentication methods:zPre-Shared KeyUsers must manually enter a key (pass phrase) on the client sideof the wireless network that matches the key stored by theadministrator in your Wi-Fi Arrays.zRADIUS 802.1x with EAP802.1x uses a RADIUS server to authenticate large numbers ofclients, and can handle different EAP (Extensible AuthenticationProtocol) 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 RADIUSserver offers more functionality and is recommended for largeEnterprise deployments.When using this method, user names and passwords must beentered into the RADIUS server for user authentication.
Wi-Fi ArrayAppendix C: Technical Support 405zMAC Address ACLs (Access Control Lists)MAC address ACLs provide a list of client adapter MACaddresses that are allowed or denied access to the wirelessnetwork. Access Control Lists work well when there are a limitednumber of users—in this case, enter the MAC addresses of eachuser in the Allow list. In the event of a lost or stolen MACadapter, enter the affected MAC address in the Deny list.Q. Why do I need to authenticate my Wi-Fi Array units?A. When deploying multiple Wi-Fi Arrays, you may need to define whichunits are part of which wireless network (for example, if you areestablishing more than one network). In this case, you need to employ theXirrus Management System (XMS) which can authenticate your Arraysautomatically and ensure that only authorized units are associated withthe defined wireless network.Q. What is rogue AP (Access Point) detection?A. The Wi-Fi Array has a dedicated radio, IAP abg(n)2, which constantlyscans the local wireless environment for rogue APs (non-Xirrus devicesthat are not part of your wireless network), unencrypted transmissions,and other security issues. Administrators can then classify each rogue APand ensure that these devices do not interrupt or interfere with thenetwork.See AlsoContact InformationGeneral Hints and TipsMultiple SSIDsVLAN SupportVLAN SupportQ. What Are VLANs?A. VLANs (Virtual Local Area Networks) are a logical grouping of networkdevices that share a common network broadcast domain. Members of a
Wi-Fi Array406 Appendix C: Technical Supportparticular VLAN can be on any segment of the physical network butlogically only members of a particular VLAN can see each other.VLANs are defined and implemented using the wired network switchesthat are VLAN capable. Packets are tagged for transmission on aparticular VLAN according to the IEEE 802.1Q standard, with VLANswitches processing packets according to the tag.Q. What would I use VLANs for?A. Logically separating different types of users, systems, applications, orother logical division aids in performance and management of differentnetwork devices. Different VLANs can also be assigned with differentpacket priorities to prioritize packets from one VLAN over packets fromanother VLAN.VLANs are managed by software settings—instead of physicallyplugging in and moving network cables and users—which helps to easenetwork management tasks.Q. What are Wireless VLANs?A. Wireless VLANs allow similar functionality to the wired VLANdefinitions and extend the operation of wired VLANs to the wireless sideof the network.Wireless VLANs can be mapped to wireless SSIDs so that traffic fromwired VLANs can be sent to wireless users of a particular SSID. Thereverse is also true, where wireless traffic originating from a particularSSID can be tagged for transmission on a particular wired VLAN.Sixteen SSIDs can be defined on your Wi-Fi Array, allowing a total ofsixteen VLANs to be accessed (one per SSID).As an example, to provide guest user access an SSID of guest might becreated. This SSID could be mapped to a wired VLAN that segregatesunknown users from the rest of the wired network and restricts them toInternet access only. Wireless users could then associate to the wirelessnetwork via the guest SSID and obtain access to the Internet through the
Wi-Fi ArrayAppendix C: Technical Support 407selected VLAN, but would be able to access other privileged networkresources.See AlsoContact InformationGeneral Hints and TipsMultiple SSIDsSecurity
Wi-Fi Array408 Appendix C: Technical SupportArray Monitor and Radio Assurance CapabilitiesAll models of the Wi-Fi Array have a monitor radio, abg(n)2, that checks that theArray’s radios are functioning correctly, and acts as a dedicated threat sensor todetect and prevent intrusion from rogue access points. Enabling Monitoring on the ArrayIAP abg(n)2 may be set to monitor the Array or to be a normal IAP radio. In orderto enable the functions required for intrusion detection and for monitoring theother Array radios, you must configure abg(n)2 on the IAP Settings window asfollows:zCheck the Enabled checkbox.zSet Mode to Monitor.zSet Channel to Monitor.The settings above will automatically set the Antenna selection toInternal-Omni., also required for monitoring. See the “IAP Settings” on page 254for more details. The values above are the factory default settings for the Array. How Monitoring WorksWhen the monitor radio abg(n)2 has been configured as just described, itperforms these steps continuously (24/7) to check the other radios on the Arrayand detect possible intrusions:1. The monitor radio scans all channels with a 200ms dwell time, hitting allchannels about once every 10 seconds.2. Each time it tunes to a new channel it sends out a probe request in anattempt to smoke out rogues.3. It then listens for all probe responses and beacons to detect any rogueswithin 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 275. Note that the Advanced setting is onlyused with the optional Xirrus Defense Module (XDM) software package.
Wi-Fi ArrayAppendix C: Technical Support 409Radio AssuranceThe Array is capable of performing continuous, comprehensive tests on its radiosto assure that they are operating properly. Testing is enabled using the RadioAssurance Mode setting on the Advanced RF Settings window (Step 5 in“Advanced RF Settings” on page 275). When this mode is enabled, IAP abg(n)2performs loopback tests on the Array. Radio Assurance Mode requires IntrusionDetection to be set to Standard (See Step 1 in “Advanced RF Settings” onpage 275). When Radio Assurance Mode is enabled:1. The Array keeps track of whether or not it hears beacons and proberesponses from the Array’s radios. 2. After 10 minutes (roughly 60 passes on a particular channel by themonitor radio), if it has not heard beacons or probe responses from one ofthe Array’s radios it issues an alert in the Syslog. If repair is allowed (see“Radio Assurance Options” on page 410), the Array will reset andreprogram that particular radio at the Physical Layer (PHY—Layer 1).This action takes under 100ms and stations are not deauthenticated, thususers should not be impacted.3. After another 10 minutes (roughly another 60 passes), if the monitor stillhas not heard beacons or probe responses from the malfunctioning radioit will again issue an alert in the Syslog. If repair is allowed, the Array willreset 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. Thisaction takes roughly 300ms and stations are not deauthenticated, thususers should not be impacted.4. After another 10 minutes, if the monitor still has not heard beacons orprobe responses from that radio, it will again syslog the issue. If reboot isallowed (see “Radio Assurance Options” on page 410), the Array willschedule 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 Array410 Appendix C: Technical SupportRadio Assurance OptionsIf the monitor detects a problem with an Array radio as described above, it willtake action according to the preference that you have specified in the RadioAssurance Mode setting on the Advanced RF Settings window (see Step 5page 278):zFailure alerts only—The Array will issue alerts in the Syslog, but will notinitiate repairs or reboots.zFailure alerts & repairs, but no reboots—The Array will issue alerts andperform 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 describedabove. zDisabled—Disable IAP loopback tests (no self-monitoring occurs).Loopback tests are disabled by default.
Wi-Fi ArrayAppendix C: Technical Support 411Upgrading the Array via CLIIf you are experiencing difficulties communicating with the Array using the WebManagement Interface, the Array provides lower-level facilities that may be usedto accomplish an upgrade via the CLI and the Xirrus Boot Loader (XBL).1. Download the latest software update from the Xirrus FTP site using yourEnhanced Care FTP username and password. If you do not have an FTPusername 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 filename in case you need it later on—you may also need to copy this fileelsewhere on the network depending on your situation.2. Install a TFTP server software package if you don't have one running. Itmay be installed on any PC on your network, including your desktop orlaptop. 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 maybe changed if desired. This directory is where you will place the extractedXirrus software update file(s). If you install the TFTP server on the samecomputer to which you extracted the file, you may change the TFTPdirectory to C:\xirrus if desired. You must make the following change to the default configuration of theSolar Winds TFTP server. In the File/Configure menu, select Security,then select Transmit only and click OK.3. Determine the IP address of the computer hosting the TFTP server. (Todisplay 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 networkcable to the Array’s GIG1 port, if it is not already part of your network.

Wi-Fi ArrayAppendix D: Implementing Security Standards 421Appendix D: Implementing Security StandardsThis Appendix discusses two security standards which are supported by theWi-Fi Array, and discusses their implementation.zImplementing PCI DSS on the Wi-Fi ArrayzImplementing FIPS Security on the Wi-Fi ArrayImplementing PCI DSS on the Wi-Fi ArrayThe Payment Card Industry (PCI) Data Security Standard (DSS) was developedby major credit card companies to help those that process credit card transactions(or cardholder information) in order to secure cardholder information and protectit from unauthorized access, fraud and other security issues. It lays out a set ofrequirements that must be met in order to provide adequate security for sensitivedata. Implementation of PCI DSS on the Wi-Fi Array is described in the Xirrus WhitePaper, PCI Data Security Standard, available on the Xirrus web site. Thisdocument:zLists the specific requirements of PCI DSS for wireless networking. zDescribes how these requirements are satisfied by the Wi-Fi Array.zProvides a Checklist of the exact steps that must be taken in order todeploy the Array in accordance with PCI DSS.The pci-audit CommandThe Array provides a CLI command, pci-audit, that will check whether theArray’s configuration satisfies PCI DSS wireless requirements. This commanddoes not change any parameters, but will inform you of any violations that exist.Furthermore, the command pci-audit enable will monitor changes that you maketo the Array’s configuration in CLI or the WMI, and warn you (and issue a Syslogmessage) if the change violates PCI DSS requirements. Use this command inconjunction with the Xirrus Array Configuration Checklist in the White Paper toensure that you are using the Array in accordance with the PCI DSS requirements.
Wi-Fi Array422 Appendix D: Implementing Security Stan-The pci-audit command checks the following items:zTelnet is disabled.zAdmin RADIUS is enabled (admin login authentication is via RADIUSserver).zAn external Syslog server is in use. zAll SSIDs must set encryption to WPA or better (which also enforces802.1x authentication)Sample output from this command is shown below. Figure 190. Sample output of pci-audit commandImplementing FIPS Security on the Wi-Fi ArrayOn the Wi-Fi Array Wi-Fi Arrays may be configured to satisfy the requirementsfor Level 2 of Federal Information Processing Standard (FIPS) Publication 140-2.The procedure in this section lists simple steps that must be followed exactly toimplement FIPS 140-2, Level 2. The procedure includes physical actions, andparameters that must be set in Web Management Interface (WMI) windows in theSecurity section and in other sections.The following topics are discussed:z“To implement FIPS 140-2, Level 2 using WMI” on page 423.z“To check if an Array is in FIPS mode:” on page 428z“To implement FIPS 140-2, Level 2 using CLI:” on page 428SS-Array(config)# pci-auditPCI audit failure: telnet enabled.PCI audit failure: admin RADIUS authentication disabled.PCI audit failure: SSID ssid2 encryption too weak.PCI audit failure: SSID ssid3 encryption too weak.PCI audit failure: SSID ssid4 encryption too weak.PCI audit failure: SSID ssid5 encryption too weak.PCI audit failure: SSID ssid6 encryption too weak.
Wi-Fi ArrayAppendix D: Implementing Security Standards 423To implement FIPS 140-2, Level 2 using WMI1. Apply the supplied tamper-evident seals to the unit as indicated in thefigures below. The procedure is slightly different, depending on themodel.•Before you apply the tamper-evident seal, clean the area of anygrease, dirt, or oil. We recommend using alcohol-based cleaning padsfor this. •Each seal must be applied to straddle both sides of an opening so thatit will show if an attempt has been made to open the Array. •XS16, XS12, XS8, XS-3900, or XS-3700—Apply two seals, one on eitherside of the Array about 180° apart from each other, as shown. Apply athird seal to the access panel opening, as shown. IMPORTANT:Make sure that each seal straddles a seam. Figure 191. Applying Three Seals to the XS16/XS12/XS8 or XS-3900/XS-3700123

It allows Access Points to communicateinformation on the permissible radio channels with acceptable power levels foruser devices. Because the 802.11 standards cannot legally operate in somecountries, 802.11d adds features and restrictions to allow WLANs to operatewithin the rules of these countries.802.11gA supplement to the IEEE 802.11 WLAN specification that describes radiotransmissions at a frequency of 2.4 GHz and data rates of up to 54 Mbps.802.11nA supplement to the IEEE 802.11 WLAN specification that describesenhancements to 802.11a/b/g to greatly enhance reach, speed, and capacity.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 aswitch to communicate VLAN membership information across multiple (andmulti-vendor) devices by frame tagging.AES(Advanced Encryption Standard) A data encryption scheme that uses threedifferent 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 butunclassified electronic data.

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. Inother words, it identifies the maximum data rate a signal can attain onthe medium without encountering significant attenuation (loss of power).beacon intervalWhen a device in a wireless network sends a beacon, it includes with it a beaconinterval, 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 lowpower mode before waking up to handle the beacon. Network administrators canadjust the beacon interval—usually measured in milliseconds (ms) or itsequivalent, kilo-microseconds (Kmsec).bit rateThe transmission rate of binary symbols ('0' and '1'), equal to the total number ofbits transmitted in one second.BSS(Basic Service Set) When a WLAN is operating in infrastructure mode, each accesspoint 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 mostCisco equipment and some other network equipment. It is used to shareinformation with other directly connected network devices. Information such asthe model, network capabilities, and IP address is shared. Wi-Fi Arrays can bothadvertise their presence by sending CDP announcements, and gather and displayinformation sent by neighbors.
Wi-Fi ArrayGlossary of Terms 455cellThe basic geographical unit of a cellular communications system. Servicecoverage of a given area is based on an interlocking network of cells, each with aradio base station (transmitter/receiver) at its center. The size of each cell isdetermined by the terrain and forecasted number of users.channelA specific portion of the radio spectrum—the channels allotted to one ofthe wireless networking protocols. For example, 802.11b and 802.11g use 14channels in the 2.4 GHz band, only 3 of which don't overlap (1, 6, and 11). In the 5GHz band, 802.11a uses 8 channels for indoor use and 4 for outdoor use, none ofwhich overlap. In the U.S., additional channels are available, to bring the total to24 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 ofservice.default gatewayThe gateway in a network that a computer will use to access another network ifa gateway is not specified for use. In a network using subnets, a default gatewayis the router that forwards traffic to a destination outside of the subnet ofthe transmitting device.DHCP(Dynamic Host Configuration Protocol) A method for dynamically assigning IPaddresses to devices on a network. DHCP issues IP addresses automaticallywithin 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 DHCPclient for permission to use a particular IP address. A typical DHCP server allowsits administrator to set the lease time.
Wi-Fi Array456 Glossary of TermsDNS(Domain Name System) A system that maps meaningful domain names withcomplex numeric IP addresses. DNS is actually a separate network—if one DNSserver cannot translate a domain name, it will ask a second or third until a serveris found with the correct IP address.domainThe main name/Internet address of a user's Internet site as registered withthe InterNIC organization, which handles domain registration on the Internet. Forexample, the “domain” address for Xirrus is: http://www.xirrus.com, brokendown as follows:zhttp:// represents the Hyper Text Teleprocessing Protocol used by all Webpages.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 beaconby an access point to a client device in sleep mode, alerting the device to a packetawaiting delivery.EAP(Extensible Authentication Protocol) When you log on to the Internet, you're mostlikely 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 controlledvia PPP’s Link Control Protocol (LCP). However, LCP is somewhat inflexiblebecause it has to specify an authentication device early in the process. EAP allowsthe system to gather more information from the user before deciding whichauthenticator to use. It is called extensible because it allows more authenticatortypes than LCP (for example, passwords and public keys).
Wi-Fi ArrayGlossary of Terms 457EDCF(Enhanced Distributed Coordinator Function) A QoS extension which usesthe same contention-based access mechanism as current devices but adds “offsetcontention windows” that separate high priority packets from low prioritypackets (by assigning a larger random backoff window to lower priorities than tohigher priorities). The result is “statistical priority,” where high-priority packetsusually are transmitted before low-priority packets.encapsulationA way of wrapping protocols such as TCP/IP, AppleTalk, and NetBEUI inEthernet frames so they can traverse an Ethernet network and be unwrappedwhen they reach the destination computer.encryptionAny procedure used in cryptography to translate data into a form that can bedecrypted 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 withregulating Interstate and International communications by radio, television, wire,satellite and cable.FIPSThe Federal Information Processing Standard (FIPS) Publication 140-2 establishesa computer security standard used to accredit cryptographic modules.The standard is a joint effort by the U.S. and Canadian governments. frameA packet encapsulated to travel on a physical medium, like Ethernet or Wi-Fi. If apacket is like a shipping container, a frame is the boat on which the shippingcontainer is loaded. Gigabit 1The primary Gigabit Ethernet interface. See also, Gigabit Ethernet.
Wi-Fi Array458 Glossary of TermsGigabit 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).GroupA 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 allusers that are members of the group. This allows a uniform configuration to beeasily applied to multiple user accounts. The attributes that can be configured foruser 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 sitethe host name is the same as the domain name. One computer can have more thanone 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 isthe 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 amanufacturer to a device.Mbps(Megabits per second) A standard measure for data transmission speeds (forexample, the rate at which information travels over the Internet). 1 Mbps denotesone million bits per second.
Wi-Fi ArrayGlossary of Terms 459MTU(Maximum Transmission Unit) The largest physical packet size—measured inbytes—that a network can transmit. Any messages larger than the MTU aredivided into smaller packets before being sent. Every network has a differentMTU, which is set by the network administrator. Ideally, you want the MTU to bethe same as the smallest MTU of all the networks between your machine anda message's final destination. Otherwise, if your messages are larger than one ofthe intervening MTUs, they will get broken up (fragmented), which slows downtransmission speeds.NTP(Network Time Protocol) An Internet standard protocol (built on top of TCP/IP)that ensures the accurate synchronization (to the millisecond) of computer clocktimes in a network of computers. Running as a continuous background clientprogram on a computer, NTP sends periodic time requests to servers, obtainingserver time stamps and using them to adjust the client's clock.packetData sent over a network is broken down into many small pieces—packets—bythe Transmission Control Protocol layer of TCP/IP. Each packet contains theaddress of its destination as well the data. Packets may be sent on any number ofroutes to their destination, where they are reassembled into the original data. Thissystem is optimal for connectionless networks, such as the Internet, where thereare no fixed connections between two locations.PLCP(Physical Layer Convergence Protocol) Defined by IEEE 802.6, a protocolspecified within the Transmission Convergence layer that defines exactly howcells are formatted within a data stream for a particular type of transmissionfacility.PoGE This refers to the optional Xirrus XP1 Power over Gigabit Ethernet modules thatprovide DC power to Arrays. Power is supplied over the same Cat 5e or Cat 6cable that supplies the data connection to your gigabit Ethernet switch, thuseliminating the need to run a power cable. See “Power over Gigabit EthernetCompatibility Matrix” on page 416 for a list of Xirrus PoGE modules and themodules that are compatible with each Array.
Wi-Fi Array460 Glossary of TermspreamblePreamble (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 whensending and receiving packets. PLCP has two structures, a long and a shortpreamble. All compliant 802.11b systems have to support the long preamble.The short preamble option is provided in the standard to improve the efficiencyof a network's throughput when transmitting special data, such as voice, VoIP(Voice-over IP) and streaming video.private keyIn cryptography, one of a pair of keys (one public and one private) that are createdwith the same algorithm for encrypting and decrypting messages and digitalsignatures. 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 withthe 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 createdwith the same algorithm for encrypting and decrypting messages and digitalsignatures. The public key is made publicly available for encryption anddecryption.QoS(Quality of Service) QoS can be used to describe any number of ways in whicha 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 RADIUSserver stores user profiles, which include passwords and authorization attributes.RSSI(Received Signal Strength Indicator) A measure of the energy observed by anantenna when receiving a signal.
Wi-Fi ArrayGlossary of Terms 461SDMA(Spatial Division Multiple Access) A wireless communications mode thatoptimizes the use of the radio spectrum and minimizes cost by taking advantageof 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 regulatesnetwork management over the Internet.SNTP(Simple Network Time Protocol) A simplified version of NTP. SNTP can be usedwhen the ultimate performance of the full NTP implementation described in RFC1305 is not needed or justified.SSH(Secure SHell) Developed by SSH Communications Security, Secure Shell is aprogram to log into another computer over a network, to execute commands in aremote machine, and to move files from one machine to another. The Array onlyallows SSH-2 connections. SSH-2 provides strong authentication and securecommunications over insecure channels. SSH-2 protects a network from attacks,such as IP spoofing, IP source routing, and DNS spoofing. Attackers who hasmanaged 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. Whenusing SSH-2's slogin (instead of rlogin) the entire login session, includingtransmission of password, is encrypted making it almost impossible for anoutsider to collect passwords. Be aware that your SSH utility must be set up to useSSH-2. 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 thenetwork uses the same SSID to identify itself as part of the family—when it wantsto gain access to the network or verify the origin of a data packet it is sending overthe network. In short, it is the unique name shared among all devices in a WLAN.
Wi-Fi Array462 Glossary of Termssubnet maskA mask used to determine what subnet an IP address belongs to. An IP addresshas two components: (1) the network address and (2) the host address. Forexample, consider the IP address 150.215.017.009. Assuming this is part of a ClassB 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 byscrambling 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. Transmitpower is generally measured in milliwatts, which you can convert to dBm.User groupSee Group. VLAN(Virtual LAN) A group of devices that communicate as a single network, eventhough they are physically located on different LAN segments. Because VLANsare based on logical rather than physical connections, they are extremely flexible.A device that is moved to another location can remain on the same VLANwithout any hardware reconfiguration.VLAN tagging(Virtual LAN tagging) Static port-based VLANs were originally the only way tosegment a network without using routing, but these port-based VLANs couldonly be implemented on a single switch (or switches) cabled together. Routingwas required to transfer traffic between unconnected switches. As an alternativeto routing, some vendors created proprietary schemes for sharing VLANinformation across switches. These methods would only operate on that vendor'sequipment and were not an acceptable way to implement VLANs. With theadoption of the 802.11n standard, traffic can be confined to VLANs that exist on
Wi-Fi ArrayGlossary of Terms 463multiple switches from different vendors. This interoperability and trafficcontainment across different switches is the result of a switch's ability to use andrecognize 802.1Q tag headers—called VLAN tagging. Switches that implement802.1Q tagging add this tag header to the frame directly after the destination andsource 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 itcorrectly.WDS (Wireless Distribution System)WDS creates wireless backhauls between arrays. These links between arrays maybe used rather than having to install data cabling to each array. WEP(Wired Equivalent Privacy) An optional IEEE 802.11 function that offers frametransmission privacy similar to a wired network. The Wired Equivalent Privacygenerates secret shared encryption keys that both source and destination stationscan use to alter frame bits to avoid disclosure to eavesdroppers.Wi-Fi AllianceA nonprofit international association formed in 1999 to certify interoperability ofwireless Local Area Network products based on IEEE 802.11 specification. Thegoal of the Wi-Fi Alliance's members is to enhance the user experience throughproduct interoperability.Wi-Fi ArrayA high capacity Wi-Fi networking device consisting of multiple radios arrangedin a circular array.WPA(Wi-Fi Protected Access) A Wi-Fi Alliance standard that contains a subset of theIEEE 802.11i standard, using TKIP as an encryption method and 802.1x forauthentication.
Wi-Fi Array464 Glossary of TermsWPA2 (Wi-Fi Protected Access 2) WPA2 is the follow-on security method to WPA forwireless networks and provides stronger data protection and network accesscontrol. It offers Enterprise and consumer Wi-Fi users with a high level ofassurance that only authorized users can access their wireless networks.
