Wireless Array Procedure for Configuring Network Security 1. RADIUS Server Mode: Choose the RADIUS server mode you want to use, either Internal or External. Parameters for these modes are configured in “External Radius” on page 234 and “Internal Radius” on page 238. WPA Settings These settings are used if the WPA or WPA2 encryption type is selected on the SSIDs >SSID Management window or the Express Setup window (on this window, encryption type is set in the SSID Settings: Wireless Security field). 2.
Wireless Array WEP Settings These settings are used if the WEP encryption type is selected on the SSIDs > SSID Management window or the Express Setup window (on this window, encryption type is set in the SSID Settings: Wireless Security field). Click the Show Cleartext button to make the text that you type in to the Key fields visible. WEP encryption does not support high throughput rates or features like frame aggregation or block acknowledgments (see Improved MAC Throughput), per the IEEE 802.
Wireless Array 9. Click Save changes to flash if you wish to make your changes permanent. After configuring network security, the configuration must be applied to an SSID for the new functionality to take effect.
Wireless Array External Radius This window allows you to define the parameters of an external RADIUS server for user authentication. To set up an external RADIUS server, you must choose External as the RADIUS server mode in Global Settings. Refer to “Global Settings” on page 230. Figure 130. External RADIUS Server If you want to include user group membership in the RADIUS account information for users, see “Understanding Groups” on page 269.
Wireless Array About Creating User Accounts on the RADIUS Server A number of attributes of user (wireless client) accounts are controlled by RADIUS Vendor Specific Attributes (VSAs) defined by Xirrus. For example, you would use the VSA named Xirrus-User-VLAN if you wish to set the VLAN for a user account in RADIUS. For more information about the RADIUS VSAs used by Xirrus, see “RADIUS Vendor Specific Attribute (VSA) for Xirrus” on page 491. Procedure for Configuring an External RADIUS Server 1.
Wireless Array 3. Settings (RADIUS Dynamic Authorization): Some RADIUS servers have the ability to contact the Array (referred to as an NAS, see below) to terminate a user with a Disconnect Message (DM). Or RADIUS may send a Change-of-Authorization (CoA) Message to the Array to change a user’s privileges due to changing session authorizations. This implements RFC 5176—Dynamic Authorization Extensions to RADIUS. a.
Wireless Array b. Station MAC Format: Define the format of the Station MAC RADIUS attribute sent from the Array—lower-case or upper-case, hyphenated or not. The default is lower-case, not hyphenated. 5. Accounting Settings: Note that RADIUS accounting start packets sent by the Array will include the client station's Framed-IP-Address attribute. a. Accounting Interval (seconds): Specify how often Interim records are to be sent to the server. The default is 300 seconds. b.
Wireless Array Global Settings (IAP) Internal Radius Access Control List Management Control Security Understanding Groups Internal Radius This window allows you to define the parameters for the Array’s internal RADIUS server for user authentication. However, the internal RADIUS server will only authenticate wireless clients that want to associate to the Array. This can be useful if an external RADIUS server is not available.
Wireless Array Clients using PEAP may have difficulty authenticating to the Array using the Internal RADIUS server due to invalid security certificate errors. To prevent this problem, the user may disable the Validate Server Certificate option on the station. Do this by displaying the station’s wireless devices and then displaying the properties of the desired wireless interface. In the security properties, disable Validate server certificate.
Wireless Array 4. Verify Password: (Optional) Retype the user password to verify that you typed it correctly. 5. If you want to delete one or more users, click their Delete buttons. 6. Click Save changes to flash if you wish to make your changes permanent.
Wireless Array Rogue Control List This window allows you to set up a control list for rogue APs, based on a type that you define. You may classify rogue APs as blocked, so that the Array will take steps to prevent stations from associating with the blocked AP. See “About Blocking Rogue APs” on page 337. The Array can keep up to 5000 entries in this list. The RF Monitor > Intrusion Detection window provides an alternate method for classifying rogues.
Wireless Array Rogue Control List contains two entries that match 00:0f:7d:* and 50:60:28:* and apply the classification Known to all Xirrus Arrays. 2. Rogue Control Classification: Enter the classification for the specified rogue AP(s), either Blocked, Known or Approved. 3. Match Only: Select the match criterion to compare the Rogue BSSID/ SSID string against: BSSID, Manufacturer, or SSID. The BSSID field contains the MAC address. 4. Click Create to add this rogue AP to the Rogue Control List. 5.
Wireless Array OAuth 2.0 Management This window displays a list of tokens granted by the Array for access to its RESTful API (see “API Documentation” on page 387 for a description of the features available in the API). OAuth 2.0 is used to provide the tokens. The list will be blank until tokens have been issued as described below. You may revoke (delete) existing tokens from the list, if desired. Xirrus Arrays use the OAuth 2.0 standard’s client credential grant model.
Wireless Array https://[Array hostname or IP address]/oauth/authorize • grant_type: password • username: username of an administrator account on the Array. • client_id: username of an administrator account on the Array (username and client_id must match). • password: password for the same administrator account on the Array The OAuth Authorization API provides a permanent token that the application may use to access the RESTful API.
Wireless Array SSIDs This status-only window allows you to review SSID (Service Set IDentifier) assignments. It includes the SSID name, whether or not an SSID is visible on the network, any security and QoS parameters defined for each SSID, associated VLAN IDs, radio availability, and DHCP pools defined per SSID. Click on an SSID’s name to jump to the edit page for the SSID.
Wireless Array SSIDs are managed with the following windows: “SSID Management” on page 253 “Active IAPs” on page 266 “Per-SSID Access Control List” on page 267 SSIDs are discussed in the following topics: “Understanding SSIDs” on page 246 “Understanding QoS Priority on the Wireless Array” on page 247 “High Density 2.
Wireless Array Using SSIDs 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: The wireless security mode needed to join this SSID. The wireless Quality of Service (QoS) desired for this SSID. The wired VLAN associated with this SSID.
Wireless Array Application Data Voice Data Video Data Background Data Best Effort Data Mapping to Traffic Class Four Transmit Queues Per queue channel access IAP (Transmit) Highest Priority Lowest Priority Figure 135. Four Traffic Classes The Wireless Array’s Quality of Service Priority feature (QoS) allows traffic to be prioritized according to your requirements. For example, you typically assign the highest priority to voice traffic, since this type of traffic requires delay to be under 10 ms.
Wireless Array user priority levels and the Array implements four wireless QoS levels, user priorities are mapped to QoS as described below. Figure 137. Priority Level—DSCP (DiffServ - Layer 3) DSCP (Differentiated Services Code Point or DiffServ) uses 6 bits in the IPv4 or IPv6 packet header, defined in RFC2474 and RFC2475. The DSCP value classifies a Layer 3 packet to determine the Quality of Service (QoS) required. DSCP replaces the outdated Type of Service (TOS) field.
Wireless Array FROM Priority Tag 802.1p (Wired) TO Array QoS (Wireless) Typical Use 2 1 Spare 3 0 Excellent Effort 4 2 Controlled Load 5 2 Video 6 3 Voice - requires delay <10ms 7 (Highest priority) 3 (Highest priority) Network control Egress: Outgoing wired packets are IEEE 802.1p tagged at the Ethernet port for upstream traffic, thus enabling QoS at the edge of the network. FROM Array QoS (Wireless) TO Priority Tag 802.
Wireless Array How QoS is set for a packet in case of conflicting values: a. If an SSID has a QoS setting, and an incoming wired packet’s user priority tag is mapped to a higher QoS value, then the higher QoS value is used. b. If a group or filter has a QoS setting, this overrides the QoS value above. See “Groups” on page 269, and “Filters” on page 351. c. Voice packets have the highest priority (see Voice Support, below). d.
Wireless Array High Density 2.4G Enhancement—Honeypot SSID Some situations pose problems for all wireless APs. For example, iPhones will remember every SSID and flood the airwaves with probes, even when the user doesn’t request or desire this behavior. In very high density deployments, these probes can consume a significant amount of the available wireless bandwidth. The Array offers a feature targeting this problem—a “honeypot” SSID.
Wireless Array SSID Management This window allows you to manage SSIDs (create, edit and delete), assign security parameters and VLANs on a per SSID basis, and configure the Web Page Redirect functionality. Create new SSID Configure parameters Set traffic limits / usage schedule Configure encryption/authentication Configure RADIUS server Figure 138.
Wireless Array Procedure for Managing SSIDs 1. New SSID Name: To create a new SSID, enter a new SSID name to the left of the Create button (Figure 138), then click Create. SSID names are case sensitive and may only consist of the characters A-Z, a-z, 0-9, dash, and underscore. You may create up to 16 SSIDs (up to 8 on the XR-500 Series).
Wireless Array compromising the performance of the network. Use this setting in environments where traffic prioritization is not a concern. • 1 — Medium, with QoS prioritization aggregated across all traffic types. • 2 — High, normally used to give priority to video traffic. • 3 — The highest QoS priority setting, normally used to give priority to voice traffic.
Wireless Array 11. Encryption: From the pull-down list, choose the encryption that will be required — specific to this SSID — either None, WEP, WPA, WPA2 or WPA-Both. The None option provides no security and is not recommended; WPA2 provides the best practice Wi-Fi security. Each SSID supports only one encryption type at a time (except that WPA and WPA2 are both supported on an SSID if you select WPA-Both). If you need to support other encryption types, you must define additional SSIDs.
Wireless Array Configuration encryption settings have the same parameters as those described in “Procedure for Configuring Network Security” on page 231. The external RADIUS and accounting settings are configured in the same way as for an external RADIUS server (see “Procedure for Configuring an External RADIUS Server” on page 235). Note that external RADIUS servers may be specified using IP addresses or domain names. 13.
Wireless Array clients from associating. Since the Array’s network connectivity has failed, this gives clients a chance to connect to other, operational parts of the wireless network. No changes are made to WDS configuration. See Step a on page 225 for more information on Network Assurance. 16. Mobile Device Management (MDM): If you are an AirWatch customer and wish to have AirWatch manage mobile device access to the wireless network on this SSID, select AirWatch from the drop-down list.
Wireless Array 18. Overall Traffic: Choose Unlimited if you do not want to place a restriction on the traffic for this SSID, or enter a value in the Packets/Sec field to force a traffic restriction. 19. Traffic per Station: Choose Unlimited if you do not want to place a restriction on the traffic per station for this SSID, or enter a value in the Packets/Sec field or the Kbps field to force a traffic restriction. If you set both values, the Array will enforce the limit it reaches first. 20.
Wireless Array 24. To delete SSIDs, click their Delete buttons. 25. Click Save changes to flash if you wish to make your changes permanent. Web Page Redirect Configuration Settings If you enable WPR, the SSID Management window displays additional fields that must be configured. For example configurations and complete examples, please see the Xirrus Web Page Redirect Application Note in the Xirrus Resource Center.
Wireless Array This option displays a login page (residing on the Array) instead of the first user-requested URL. There is an upload function that allows you to replace the default login page, if you wish. Please see “Web Page Redirect” on page 382 for more information. To set up internal login, set Server to Internal Login. Set HTTPS to On for a secure login, or select Off to use HTTP. You may also customize the login page with logo and background images and header and footer text.
Wireless Array the captured URL. If you want the user redirected to a specific landing page instead, enter its address in Landing Page URL. External Login page This option redirects the user to a login page on an external web server for authentication, instead of the first user-requested URL. Login information (user name and password) must be obtained by that page, and returned to the Array for authentication. Authentication occurs according to your configured RADIUS information.
Wireless Array After the splash page, the user is redirected to the captured URL. If you want the user redirected to a specific landing page instead, enter its address in Landing Page URL. Landing Page Only This option redirects the user to a specific landing page. If you select this option, enter the desired address in Landing Page URL.
Wireless Array Logo Image — specify an optional jpg, gif, or png file to display at the top of the page. Header Text File — specify an optional .txt file to display at the top of the page (beneath the logo, if any). Footer Text File — specify an optional .txt file to display at the bottom of the page.
Wireless Array Note the following details of the operation of this feature: The list is configured on a per-SSID basis. You must have WPR enabled for the SSID to see this section of the SSID Management page. When a station that has not yet passed the WPR login/splash page attempts to access one of the white-listed addresses, it will be allowed access to that site as many times as requested.
Wireless Array See Also DHCP Server External Radius Global Settings (IAP) Internal Radius Security Planning SSIDs Understanding QoS Priority on the Wireless Array AirWatch Active IAPs By default, when a new SSID is created, that SSID is active on all IAPs. This window allows you to specify which IAPs will offer that SSID. Put differently, you can specify which SSIDs are active on each IAP. This feature is useful in conjunction with WDS.

Wireless Array Procedure for Configuring Access Control Lists 1. SSID: Select the SSID whose ACL you wish to manage. 2. Access Control List Type: Select Disabled to disable use of the Access Control List for this SSID, or select the ACL type — either Allow List or Deny List. • Allow List: Only allows the listed MAC addresses to associate to the Array. All others are denied. • Deny List: Denies the listed MAC addresses permission to associate to the Array. All others are allowed.
Wireless Array Groups This is a status-only window that allows you to review user (i.e., wireless client) Group assignments. It includes the group name, Radius ID, Device ID, VLAN IDs and QoS parameters and roaming layer defined for each group, and DHCP pools and web page redirect information defined for the group. You may click on a group’s name to jump to the edit page for the group.
Wireless Array A group allows you to define a set of parameter values to be applied to selected users. For example, you might define the user group Students, and set its VLAN, security parameters, web page redirect (WPR), and traffic limits. When a new user is created, you can apply all of these settings just by making the user a member of the group. The group allows you to apply a uniform configuration to a set of users in one step.
Wireless Array Radius ID to the Array. This will allow the Array to identify the group to which the user belongs. See Also External Radius Internal Radius SSIDs Understanding QoS Priority on the Wireless Array Web Page Redirect Configuration Settings Understanding Fast Roaming Group Management This window allows you to manage groups (create, edit and delete), assign usage limits and other parameters on a per group basis, and configure the Web Page Redirect functionality. Figure 146.
Wireless Array Procedure for Managing Groups 1. New Group Name: To create a new group, enter a new group name next to the Create button, then click Create. You may create up to 16 groups (up to 8 on the XR-500 Series). To configure and enable this group, proceed with the following steps. 272 2. Group: This column lists currently defined groups. When you create a new group, the group name appears in this list. Click on any group to select it, and then proceed to modify it as desired. 3.
Wireless Array 7. VLAN ID: (Optional) From the pull-down list, select a VLAN for this user’s traffic to use. Select numeric and enter the number of a previously defined VLAN (see “VLANs” on page 199). This user group’s VLAN settings supersede Dynamic VLAN settings (which are passed to the Array by the Radius server). To avoid confusion, we recommend that you avoid specifying the VLAN for a user in two places. 8.
Wireless Array 12. WPR (Web Page Redirect): (Optional) Check this box if you wish to enable the Web Page Redirect functionality. This will open a Web Page Redirect details section in the window, where your WPR parameters may be entered. This feature may be used to display a splash screen when a user first associates to the wireless network. After that, it can (optionally) redirect the user to an alternate URL. See “Web Page Redirect Configuration Settings” on page 260 for details of WPR configuration.
Wireless Array 13. Stations: Enter the maximum number of stations allowed on this group. The default is 1536. 14. Overall Traffic: Check the Unlimited checkbox if you do not want to place a restriction on the traffic for this group, or enter a value in the Packets/Sec field and make sure that the Unlimited box is unchecked to force a traffic restriction. 15.
Wireless Array IAPs This status-only window summarizes the status of the Integrated Access Points (radios). For each IAP, it shows whether it is up or down, the channel and wireless mode, the antenna that it is currently using, its cell size and transmit and receive power, how many users (stations) are currently associated to it, whether it is part of a WDS link, and its MAC address. Figure 147.
Wireless Array Figure 148. Source of Channel Setting Arrays have a fast roaming feature, allowing them to maintain sessions for applications such as voice, even while users cross boundaries between Arrays. Fast roaming is set up in the Global Settings (IAP) window and is discussed in: “Understanding Fast Roaming” on page 278 IAPs are configured using the following windows: “IAP Settings” on page 279 “Global Settings (IAP)” on page 285 “Global Settings .
Wireless Array “Roaming Assist” on page 342 See Also IAP Statistics Summary Understanding Fast Roaming To maintain sessions for real-time data traffic, such as voice and video, users must be able to maintain the same IP address through the entire session. With traditional networks, if a user crosses VLAN or subnet boundaries (i.e., roaming between domains), a new IP address must be obtained.
Wireless Array IAP Settings This window allows you to enable/disable IAPs, define the wireless mode for each IAP, specify the channel to be used and the cell size for each IAP, lock the channel selection, establish transmit/receive parameters, select antennas, and reset channels. Buttons at the bottom of the list allow you to Reset Channels, Enable All IAPs, or Disable All IAPs. When finished, click Save changes to flash if you wish to make your changes permanent. Figure 149.
Wireless Array For all 802.11ac settings, go to “Global Settings .11ac” on page 312. Procedure for Manually Configuring IAPs 1. In the Enabled column, check the box for an IAP to enable it, or uncheck the box if you want to disable the IAP. 2. In the Band column, select the wireless band for this IAP from the choices available in the pull-down menu, either 2.4GHz or 5 GHz. Choosing the 5GHz band will automatically select an adjacent channel for bonding.
Wireless Array 802.11n stations only on selected radios in your network, the rest of your 802.11ac IAPs will have greatly improved performance. Take care to ensure that your network provides adequate coverage for the types of stations that you need to support. 4. In the Channel column, select the channel you want this IAP to use from the channels available in the pull-down list. The list shows the channels available for the IAP selected (depending on which band the IAP is using).
Wireless Array • Channel number — If a channel number appears, then this channel is already bonded to the listed channel. • Off — Do not bond his channel to another channel. • On — Bond this channel to an adjacent channel. The bonded channel is selected automatically by the Array based on the Channel (Step 4). The choice of banded channel is static — fixed once the selection is made. • +1 — Bond this channel to the next higher channel number. Auto Channel bonding does not apply.
Wireless Array goes offline, an adjacent Array can increase its cell size to help compensate. The number of users and their applications are major drivers of bandwidth requirements. The network architect must account for the number of users within the Array’s cell diameter. In a large office, or if multiple Arrays are in use, you may choose Small cells to achieve a higher data rate, since walls and other objects will not define the cells naturally.
Wireless Array 11. You may reset all of the enabled IAPs by clicking the Reset Channels button at the bottom of the list. A message will inform you that all enabled radios have been taken down and brought back up. 12. Buttons at the bottom of the list allow you to Enable All IAPs or Disable All IAPs. 13. Click Save changes to flash if you wish to make your changes permanent. See Also Coverage and Capacity Planning Global Settings (IAP) Global Settings .11an Global Settings .11bgn Global Settings .
Wireless Array Global Settings (IAP) Figure 150.
Wireless Array This window allows you to establish global IAP settings. Global IAP settings include enabling or disabling all IAPs (regardless of their operating mode), and changing settings for beacons, station management, and advanced traffic optimization — including multicast processing, load balancing, and roaming. Changes you make on this page are applied to all IAPs, without exception. Procedure for Configuring Global IAP Settings 1. Country: This is a display-only value.
Wireless Array Beacon Configuration 6. Beacon Interval: When the Array sends a beacon, it includes with it a beacon interval, which specifies the period of time before it will send the beacon again. Enter the desired value in the Beacon Interval field, between 20 and 1000 Kusecs. A Kusec is 1000 microseconds = 1 millisecond. The value you enter here is applied to all IAPs. 7.
Wireless Array load and channel conditions. If the network is not congested, it accepts the request and grants the client the medium time for its traffic stream. Otherwise, it rejects the request. This enables the Array to maintain QoS when the WLAN becomes congested after a connection has already been established.
Wireless Array exceeded, so entering unlimited, in practice, will stop at the per-IAP limit. If you have an unlicensed Array, this value is set to 1, which simply allows you to test the ability to connect to the Array. 16. Max Station Association per IAP: This defines how many station associations are allowed per IAP. The maximum is 240 (up to 120 on the XR-500 Series). Note that the SSIDs > SSID Management window also has a station limit option — Station Limit, and the windows for Global Settings .
Wireless Array • for compatibility with ordinary operation, i.e., there is no optimization or modification of multicast traffic. • if you have an application where many subscribers need to see the multicast—a large enough number that it would be less efficient to convert to unicast and better just to send out multicast even though it must be sent out at the speed of the slowest connected station.
Wireless Array (mDNS) are in use. For example, Apple Bonjour finds local network devices such as printers or other computers using mDNS. By default, the list contains the IPv4 multicast address for Apple Bonjour mDNS: 224.0.0.251. To add a new IP address to the list, type it in the top field and click the Add button to its right. You may only enter IP addresses—host names are not allowed. This is because mDNS is a link local multicast address, and does not require IGMP to the gateway.
Wireless Array • In MDNS Filter, specify the mDNS service types that are allowed to be forwarded. • If you leave this field blank, then there is no filter, and mDNS packets for all service types are passed. • If you enter service types, then this acts as an allow filter, and mDNS packets are passed only for the listed service types. Note that mDNS filtering may be used to filter the mDNS packet types that are forwarded within the same VLAN.
Wireless Array select it in the list and click Delete. To remove all entries from the list, click Reset. 22. Multicast VLAN Forwarding: This is a list of VLANs that participate in the multicast forwarding. Please see the description of multicast forwarding in Step 21 above. The VLANs you enter must be explicitly defined (see “VLANs” on page 199) in order to participate in multicast forwarding. In fact, the Array discards packets from undefined VLANs.
Wireless Array 23. MDNS Filter: There are many different types of services that may be specified in multicast query and response packets. The mDNS filters let you restrict forwarding, so that multicast packets are forwarded only for the services that you explicitly specify. This list may be used to restrict the amount of Apple Bonjour multicast traffic forwarding. For example, you may restrict forwarding to just AppleTV and printing services.
Wireless Array performance possible. The benefit is dramatic. Consider a properly designed network (having -70db or better everywhere), where virtually every client should have a 54Mbps connection. In this case, broadcasts and multicasts will all go out at 54Mbps vs. the standard rate. Thus, with broadcast rate optimization on, broadcasts and multicasts use between 2% and 10% of the bandwidth that they would in Standard mode.
Wireless Array • Off: ARP filtering is disabled. ARP requests are broadcast to radios that have stations associated to them. • Pass-thru: The Array forwards the ARP request. It passes along only ARP messages that target the stations that are associated to it. This is the default value. • Proxy: The Array replies on behalf of the stations that are associated to it. The ARP request is not broadcast to the stations.
Wireless Array • Tunneled — in this Layer 3 technique, fast roaming target Arrays must be explicitly specified. To enable fast roaming, choose Broadcast or Tunneled, and set additional fast roaming attributes (Step 30). To disable fast roaming, choose Off. If you enable Fast Roaming, the following ports cannot be blocked: • Port 22610 — reserved for Layer 2 roaming using UDP to share PMK information between Arrays. • Ports 15000 to 17999 — reserved for Layer 3 roaming (tunneling between subnets). 30.
Wireless Array Global Settings .11an This window allows you to establish global 802.11a IAP settings. These settings include defining which 802.11a data rates are supported, enabling or disabling all 802.11an IAPs, auto-configuration of channel allocations for all 802.11an IAPs, and specifying the fragmentation and RTS thresholds for all 802.11an IAPs. Figure 151. Global Settings .11an Procedure for Configuring Global 802.11an IAP Settings 1. 298 802.
Wireless Array 2. Data Rate Presets: The Wireless Array can optimize your 802.11a data rates automatically, based on range or throughput. Click Optimize Range to optimize data rates based on range, or click Optimize Throughput to optimize data rates based on throughput. The Restore Defaults button will take you back to the factory default rate settings. 3. 802.11a IAP Control: Click Enable 802.11a IAPs to enable all 802.11an IAPs for this Array, or click Disable 802.11a IAPs to disable all 802.11an IAPs.
Wireless Array • Non-Radar: give preference to channels that are not required to use dynamic frequency selection (DFS) to avoid communicating in the same frequency range as some radar (also see Step 8 on page 287).
Wireless Array For an overview of RF power and cell size settings, please see “RF Power & Sensitivity” on page 323, “Capacity and Cell Sizes” on page 32, and “Fine Tuning Cell Sizes” on page 33. 6. Auto Cell Period (seconds): You may set up auto-configuration to run periodically, readjusting optimal cell sizes for the current conditions. Enter a number of seconds to specify how often auto-configuration will run. If you select None, then auto-configuration of cell sizing will not be run periodically.
Wireless Array Smaller fragmentation numbers can help to “squeeze” packets through in noisy environments. Enter the desired Fragmentation Threshold value in this field, between 256 and 2346. 12. RTS Threshold: The RTS (Request To Send) Threshold specifies the packet size. Packets larger than the RTS threshold will use CTS/RTS prior to transmitting the packet — useful for larger packets to help ensure the success of their transmission. Enter a value between 1 and 2347. 13.
Wireless Array Global Settings .11bgn This window allows you to establish global 802.11b/g IAP settings. These settings include defining which 802.11b and 802.11g data rates are supported, enabling or disabling all 802.11b/g IAPs, auto-configuring 802.11b/g IAP channel allocations, and specifying the fragmentation and RTS thresholds for all 802.11b/g IAPs. Figure 152. Global Settings .
Wireless Array Procedure for Configuring Global 802.11b/g IAP Settings 1. 802.11g Data Rates: The Array allows you to define which data rates are supported for all 802.11g radios. Select (or deselect) 11g data rates by clicking in the corresponding Supported and Basic data rate check boxes. • Basic Rate — a wireless station (client) must support this rate in order to associate. • Supported Rate — data rates that can be used to transmit to clients. 2. 802.
Wireless Array data about its RF environment. In this case, it will pick a set of compatible channel assignments at random. On the XR-500 and XR-1000 Series Arrays, the Factory Defaults button will not restore iap1 to monitor mode. You will need to restore this setting manually. Also, you may need to set Timeshare Mode again - see “RF Monitor” on page 321. The following options may be selected for auto configuration: • Negotiate: negotiate air-time with other Arrays before performing a full scan.
Wireless Array 7. Auto Cell Period (seconds): You may set up auto-configuration to run periodically, readjusting optimal cell sizes for the current conditions. Enter a number of seconds to specify how often auto-configuration will run. If you select None, then auto-configuration of cell sizing will not be run periodically. You do not need to run Auto Cell often unless there are a lot of changes in the environment.
Wireless Array older, slower 802.11b stations. Protection avoids collisions by preventing 802.11b and 802.11g stations from transmitting simultaneously. When Auto CTS or Auto RTS is enabled and any 802.11b station is associated to the IAP, additional frames are sent to gain access to the wireless network. • Auto CTS requires 802.11g stations to send a slow Clear To Send frame that locks out other stations. Automatic protection reduces 802.11g throughput when 802.
Wireless Array 17. RTS Threshold: The RTS (Request To Send) Threshold specifies the packet size. Packets larger than the RTS threshold will use CTS/RTS prior to transmitting the packet — useful for larger packets to help ensure the success of their transmission. Enter a value between 1 and 2347. 18. Max Stations: This defines how many station associations are allowed per 802.11bgn IAP.
Wireless Array Global Settings .11n This window allows you to establish global 802.11n IAP settings. These settings include enabling or disabling 802.11n mode for the entire Array, specifying the number of transmit and receive chains (data stream) used for spatial multiplexing, setting a short or standard guard interval, auto-configuring channel bonding, and specifying whether auto-configured channel bonding will be static or dynamic. Before changing your settings for 802.
Wireless Array Procedure for Configuring Global 802.11n IAP Settings 1. 2. 802.11n Data Rates: The Array allows you to define which data rates are supported for all 802.11n radios. Select (or deselect) 11n data rates by clicking in the corresponding Supported and Basic data rate check boxes. • Basic Rate — a wireless station (client) must support this rate in order to associate. • Supported Rate — data rates that can be used to transmit to clients. 802.
Wireless Array 7. 5 GHz channel bonding: Select Dynamic to have auto-configuration for bonded 5 GHz channels be automatically updated as conditions change. For example, if there are too many clients to be supported by a bonded channel, dynamic mode will automatically break the bonded channel into two channels. Select Static to have the bonded channels remain the same once they are selected. The Dynamic option is only available when Auto bond 5 GHz channels is enabled. The default is Dynamic.
Wireless Array Global Settings .11ac This window allows you to establish global 802.11ac IAP settings. These settings include enabling or disabling 802.11ac mode for the entire Array, specifying the number of data streams used in spatial multiplexing, and setting a short or long guard interval. Before changing your settings for 802.11ac, please read the discussion in “IEEE 802.11n Deployment Considerations” on page 37. Figure 154. Global Settings .
Wireless Array Procedure for Configuring Global 802.11n IAP Settings 1. 802.11ac Mode: Select Enabled to allow the Array to operate in 802.11ac mode. If you select Disabled, then 802.11ac operation is disabled on the Array. 2. 80 MHz Guard interval: This is the length of the interval between transmission of symbols (the smallest unit of data transfer) when you are using 80MHz bonded channels.
Wireless Array Global Settings .11u Understanding 802.11u As the number of access points available in public venues increases, mobile devices users have a harder time distinguishing usable SSIDs from the tens, if not hundreds of access points visible. Using the 802.11u protocol, access points may broadcast information about the services and access that they offer and to respond to queries for additional information related to the facilities that the downstream service network provides.
Wireless Array Cellular Networks. The service network may have arrangements with one or more cellular service providers who can transparently provide wireless and Internet connectivity. Figure 155. 802.11u Global Settings Procedure for Configuring 802.11u Settings Use this window to establish the 802.11u configuration. 1. 802.11u Internetworking.

Wireless Array Advanced RF Settings This window allows you to establish RF settings, including automatically configuring channel allocation and cell size, and configuring radio assurance and standby modes. Changes you make on this page are applied to all IAPs, without exception. Figure 156.
Wireless Array About Standby Mode Standby Mode supports the Array-to-Array fail-over capability. When you enable Standby Mode, the Array functions as a backup unit, and it enables its radios if it detects that its designated target Array has failed. The use of redundant Arrays to provide this fail-over capability allows Arrays to be used in mission-critical applications. In Standby Mode, an Array monitors beacons from the target Array.
Wireless Array RF Resilience 2. Radio Assurance Mode: When this mode is enabled, the monitor radio performs loopback tests on the Array. This mode requires RF Monitor Mode to be enabled (Step 1) to enable self-monitoring functions. It also requires a radio to be set to monitoring mode (see “Enabling Monitoring on the Array” on page 488). Operation of Radio Assurance mode is described in detail in “Array Monitor and Radio Assurance Capabilities” on page 488.
Wireless Array RF Power & Sensitivity For an overview of RF power and cell size settings, please see “Capacity and Cell Sizes” on page 32 and “Fine Tuning Cell Sizes” on page 33. To use the Auto Cell Size feature, the following additional settings are required: RF Monitor Mode must be turned On. See “RF Monitor” on page 321. One of the radios must be in monitor mode, and all other IAPs that will use Auto Cell must have Cell Size set to auto. See “Procedure for Manually Configuring IAPs” on page 280. 5.
Wireless Array 10. Auto Cell Configuration: Click this button to instruct the Array to determine and set the best cell size for each enabled IAP whose Cell Size is auto on the IAP Settings window, based on changes in the environment. This is the recommended method for setting cell size. You may look at the Tx and Rx values on the IAP Settings window to view the cell size settings that were applied. 11.
Wireless Array Auto band runs separately from auto channel configuration. If the band is changed for an IAP, associated stations will be disconnected and will then reconnect. 14. Channel Configuration: Automatic channel configuration is the recommended method for channel allocation.
Wireless Array Click Factory Defaults if you wish to instruct the Array to return all IAPs to their factory preset channels. As of release 6.3, Arrays no longer all use the same factory preset values for channel assignments.
Wireless Array 18. Auto Channel List: Use All Channels selects all available channels (this does not include locked channels). Use Defaults sets the auto channel list back to the defaults. This omits newer channels (100-140) — many wireless NICs don’t support these channels. Station Assurance Station assurance monitors the quality of the connections that users are experiencing on the wireless network. You can quickly detect stations that are having problems and take steps to correct them.
Wireless Array below and will display associated information on the Station Assurance Status page. When a threshold is reached, an event is triggered, a trap is generated, and a Syslog message is logged. 20. Period: In seconds, the period of time for a threshold to be reached. For example, the Array will check whether Max Authentication Failures has been reached in this number of seconds. 21.
Wireless Array Global Settings .11n IAPs IAP Settings Radio Assurance Hotspot 2.0 Understanding Hotspot 2.0 Hotspot 2.0 is a part of the Wi-Fi Alliance’s Passpoint certification program. It specifies additional information above and beyond that found in 802.11u, which allows mobile clients to automatically discover, select, and connect to networks based on preferences and network optimization. Mobile clients that support Hotspot 2.0 are informed of an access point’s support via its beacon message.

Each of the authentication methods may specify up to five authentication parameters. To specify the parameters click on the number corresponding to the authentication method; i.e. 1, 2, 3, 4, or 5. This displays the EAP n Auth Parameter Configuration below the list of EAP Methods.
Wireless Array Intrusion Detection The Xirrus Array employs a number of IDS/IPS (Intrusion Detection System/ Intrusion Prevention System) strategies to detect and prevent malicious attacks on the wireless network. Use this window to adjust intrusion detection settings. Figure 161.
Wireless Array The Array provides a suite of intrusion detection and prevention options to improve network security. You can separately enable detection of the following types of problems: Rogue Access Point Detection and Blocking Unknown APs are detected, and may be automatically blocked based on a number of criteria. See “About Blocking Rogue APs” on page 337.
Wireless Array Type of Attack Description Disassociation Flood Flooding the Array with forged Disassociation packets. Deauthentication Flood Flooding the Array with forged Deauthenticates. EAP Handshake Flood Flooding an AP with EAP-Start messages to consume resources or crash the target. Null Probe Response Answering a station probe-request frame with a null SSID. Many types of popular NIC cards cannot handle this situation, and will freeze up.
Wireless Array Type of Attack Description Sequence number anomaly A sender may use an Add Block Address request (ADDBA - part of the Block ACK mechanism) to specify a sequence number range for packets that the receiver can accept. An attacker spoofs an ADDBA request, asking the receiver to reset its sequence number window to a new range. This causes the receiver to drop legitimate frames, since their sequence numbers will not fall in that range.
Wireless Array Procedure for Configuring Intrusion Detection RF Intrusion Detection and Auto Block Mode 1. • Standard — enables the monitor radio to collect Rogue AP information. • Off — intrusion detection is disabled. 2. Auto Block Unknown Rogue APs: Enable or disable auto blocking (see “About Blocking Rogue APs” on page 337). Note that in order to set Auto Block RSSI and Auto Block Level, you must set Auto Block Unknown Rogue APs to On. Then the remaining Auto Block fields will be active. 3.
Wireless Array without a controlling Access Point, also called an Independent Basic Service Set — IBSS). • 6. ESS/Infrastructure only — only consider auto blocking rogue APs if they are in infrastructure mode rather than ad hoc mode. Auto Block Whitelist: Use this list to specify channels to be excluded from automatic blocking. If you have enabled Auto Block, it will not be applied to rogues detected on the whitelisted channels.
Wireless Array 8. Duration Attack NAV (ms): For the duration attack, you may also modify the default duration value that is used to determine whether a packet may be part of an attack. If the number of packets having at least this duration value exceeds the Threshold number in the specified Period, an attack is detected. Impersonation Detection Settings 9. Attack/Event: The types of impersonation attack that you may detect are described in Impersonation Attacks on page 336.
Wireless Array also choose Disabled to keep the LEDs from being lit. The LEDs will still light during the boot sequence, then turn off. 2. LED Blink Behavior: This option allows you to select when the IAP LEDs blink, based on the activities you check here. From the choices available, select one or more activities to trigger when the LEDs blink. For default behavior, see “Array LED Operating Sequences” on page 65. 3.

To change the QoS level applied to a DSCP value, click the desired QoS level (0 to 3) underneath it.
Wireless Array threshold and the stronger neighbor radio’s RSSI, then we “assist” the client. For example: Threshold = -5 RSSI of neighbor Array = -65 RSSI of client = -75 -75 < (-5 + -65) : Client will roam Another example: Threshold = -15 RSSI of neighbor Array = -60 RSSI of station = -70 -70 > (-15 + -60) : Client will not roam Procedure for Configuring Roaming Assist 1. Enable Roaming Assist: Use the Yes and No buttons to enable or disable this feature. 2.

Wireless Array WDS This is a status-only window that provides an overview of all WDS links that have been defined. WDS (Wireless Distribution System) is a system that enables the interconnection of access points wirelessly, allowing your wireless network to be expanded using multiple access points without the need for a wired backbone to link them. The Summary of WDS Client Links shows the WDS links that you have defined on this Array and identifies the target Array for each by its base MAC address.
Wireless Array and the maximum number of IAPs in the link. Then you will select the IAPs to be used in the link. When the client link is created, each member IAP will associate to an IAP on the host Array. You may wish to consider configuring the WDS link IAPs so that only the WDS link SSIDs are active on them. See “Active IAPs” on page 266. Client Link CLIENT a2(52) a10(52) a3(149) a9(149) a4(40) a8(40) Wired LAN HOST Figure 166.
Wireless Array Long Distance Links If you are using WDS to provide backhaul over an extended distance, use the WDS Dist. (Miles) setting to prevent timeout problems associated with long transmission times. (See “IAP Settings” on page 279) Set the approximate distance in miles between this IAP and the connected Array in the WDS Dist. (Miles) column. This will increase the wait time for frame transmission accordingly.
Wireless Array Procedure for Setting Up WDS Client Links WDS Client Link Settings: 1. 2. 348 Host Link Stations: Check the Allow checkbox to instruct the Array to allow stations to associate to IAPs on a host Array that participates in a WDS link. The WDS host IAP will send beacons announcing its availability to wireless clients. This is disabled by default. Once an IAP has been selected to act as a WDS client link, no other association will be allowed on that IAP.
Wireless Array The higher the weight, the lower the influence of a new RSSI reading. This is not exactly a percentage, but a factor in the formula for computing the current RSSI value based on new readings: StoredRSSI = (StoredRSSI * RoamingAvgWeight + NewRSSIReading * (100 - RoamingAvgWeight)) / 100 This prevents erroneous or out-of-line RSSI readings from causing the WDS link to jump to a new Array. Such readings can result from temporary obstructions, external interference, etc. 5.
Wireless Array Links. To allow any Xirrus Array to be accepted as a WDS target, enter the Xirrus OUI: 00:0f:7d:00:00:00 or 50:60:28:00:00:00 (this is useful for roaming in a mobile deployment, as described in Step 3 on page 348). 11. Target SSID: Enter the SSID that the target Array is using. 12. Username: Enter a username for this WDS link. A username and password is required if the SSID is using PEAP for WDS authentication from the internal RADIUS server. 13. Password: Enter a password for this WDS link.
Wireless Array Filters The Wireless Array’s integrated firewall uses stateful inspection to speed the decision of whether to allow or deny traffic. Filters are used to define the rules used for blocking or passing traffic. Filters can also set the VLAN and QoS level for selected traffic. The air cleaner feature offers a number of predetermined filter rules that eliminate a great deal of unnecessary wireless traffic. See “Air Cleaner” on page 426.
Wireless Array Filters are organized in groups, called Filter Lists. A filter list allows you to apply a uniform set of filters to SSIDs or Groups very easily. The read-only Filters window provides you with an overview of all filter lists that have been defined for this Array, and the filters that have been created in each list. Filters are listed in the left side column by name under the filter list to which they belong.
Wireless Array Procedure for Managing Filter Lists 1. Stateful Filtering: Stateful operation of the integrated firewall can be Enabled or Disabled. If you have a large number of filters and you don’t want to apply them in a stateful manner, you may use this option to turn the firewall off. 2. Application Control: Operation of the Application Control feature may be Enabled or Disabled. See “Application Control Windows” on page 147.
Wireless Array 10. Click a filter list to go to the Filter Management window to create and manage the filters that belong to this list. Filter Management This window allows you to create and manage filters that belong to a selected filter list, based on the filter criteria you specify. Filters are an especially powerful feature when combined with the intelligence provided by the “Application Control Windows” on page 147. Filters are applied in order, from top to bottom. Click here to change the order.
Wireless Array Traffic for mission-critical applications like VoIP and WebEx may be given higher priority (QoS). Non- critical traffic from applications like YouTube may be given lower priority (QoS) or bandwidth allowed may be capped per station or for all stations. Traffic flows for specific applications may be controlled by sending them into VLANs that are designated for that type of traffic. Filters may be applied at specified times—for example, no games allowed from 8 AM to 6 PM.
Wireless Array 5. On: Use this field to enable or disable this filter. 6. Log: Log usage of this filter to Syslog. 7. Type: Choose whether this filter will be an Allow filter or a Deny filter. If you define the filter as an Allow filter, then any associations that meet the filter criteria will be allowed. If you define the filter as a Deny filter, any associations that meet the filter criteria will be denied. 8. Layer: Select network layer 2 or 3 for operation of this filter. 9.
Wireless Array has the lowest priority; level 3 has the highest priority. By default, this field is blank and the filter does not modify QoS level. See “Understanding QoS Priority on the Wireless Array” on page 247. 14. VLAN/Number: (Optional) Set packets that match the filter criteria to this VLAN. Select a VLAN from the pull-down list, or select numeric and enter the number of a previously defined VLAN (see “VLANs” on page 199). 15.

Wireless Array Clusters An XR-500 or XR-1000 Series Array cannot act as the Cluster controller. It will operate correctly as a member of a cluster. Clusters allow you to configure multiple Arrays at the same time. Using WMI (or CLI), you may define a set of Arrays that are members of the cluster. Then you may enter Cluster mode for a selected cluster, which sends all successive configuration commands issued via CLI or WMI to all of the member Arrays.
Wireless Array Cluster Definition An XR-500 or XR-1000 Series Array cannot act as the Cluster controller. It will operate correctly as a member of a cluster. This window allows you to create clusters. All existing clusters are shown, along with the number of Arrays currently in each. Up to 16 clusters may be created, with up to 50 Arrays in each. Figure 173. Cluster Definition Procedure for Managing Cluster Definition 1.
Wireless Array Cluster Management An XR-500 or XR-1000 Series Array cannot act as the Cluster controller. It will operate correctly as a member of a cluster. This window allows you to add Arrays to or delete them from a selected cluster. A cluster may include a maximum of 50 Arrays. Note that the Array on which you are currently running WMI is not automatically a member of the cluster. If you would like it to be a member, you must add it explicitly. Figure 174.
Wireless Array Cluster Operation This window puts WMI into Cluster Mode. In this mode, all configuration operations that you execute in WMI or CLI are performed on the members of the cluster. They are not performed on the Array where you are running WMI, unless it is a member of the cluster. An XR-500 or XR-1000 Series Array cannot act as the Cluster controller. It will operate correctly as a member of a cluster.

Wireless Array Mobile Mobile Device Management (MDM) servers enable you to manage large-scale deployments of mobile devices. They may include capabilities to handle tasks such as enrolling devices in your environment, configuring and updating device settings over-the-air, enforcing security policies and compliance, securing mobile access to your resources, and remotely locking and wiping managed devices.
Wireless Array The Array settings entered on this page are mostly taken from AirWatch. Once you have entered these settings, your users will be constrained to follow a set of steps to access the wireless network, as described in “User Procedure for Wireless Access” on page 368.
Wireless Array 8. Redirect URL: Obtain this from your AirWatch server. Go to the System / Advanced / Site URLs page, and copy the Enrollment URL string into this field. When a mobile device that is not currently enrolled with AirWatch attempts to connect to the Array, the device displays a page directing the user to install the AirWatch agent and go to the AirWatch enrollment page. Note that Android devices will need another form of network access (i.e.
Wireless Array 5. If the device is not enrolled, all user traffic will be blocked, except that HTTP traffic is redirected to an intermediate page on the Array that tells the user to download and install the AirWatch agent. The page displays a link to the AirWatch-provided device enrollment URL. This link is a passthough that allows the user to go through the enrollment process. The user will need to enter your organization’s AirWatch Group ID and individual account credentials when requested.
Wireless Array contacted at this time and advises the user to contact the network administrator. If this field is set to Allow, then the device will be allowed network access.
Wireless Array Using Tools on the Wireless Array If you are a Cloud XMS customer, then Arrays are managed via the cloud, and local Array management interfaces are inaccessible. If the Array is being managed by your own server for XMS Release 6.5 or above, and if the Array has been assigned to a named network in XMS, you will be restricted to read-only Array access. See “XMS-Managed Arrays Restrict Local Management” on page 78.

Wireless Array This window allows you to manage files for software images, configuration, and Web Page Redirect (WPR), manage the system’s configuration parameters, reboot the system, and use diagnostic tools. About Licensing and Upgrades The Array’s license determines some of the features that are available on the Array. For example, the Application Control feature is an option that must be separately licensed. To check the features supported by your license, see “Array Information” on page 98.
Wireless Array Diagnostics Web Page Redirect Network Tools Progress and Status Frames System 1. Save & Reboot or Reboot: Use Save & Reboot to save the current configuration and then reboot the Array. The LEDs on the Array indicate the progress of the reboot, as described in “Powering Up the Wireless Array” on page 64. Alternatively, use the Reboot button to discard any configuration changes which have not been saved since the last reboot.
Wireless Array If you have difficulty upgrading the Array using the WMI, see “Upgrading the Array via CLI” on page 494 for a lower-level procedure you may use. Software Upgrade always uploads the file in binary mode. If you transfer any image file to your computer to have it available for the Software Upgrade command, it is critical to remember to transfer it (ftp, tftp) in binary mode! 3.
Wireless Array Trial licenses: If you enter a trial license to try new premium features, then when the trial expires the perpetual license will be restored automatically without requiring a reboot. When the trial expires, the current Array configuration will not be lost. Automatic Updates from Remote Image or Configuration File The Array software image or configuration file can be downloaded from an external server.
Wireless Array 6. The Remote Boot Image or Remote Configuration update happens every time that the Array reboots. If you only want to fetch the remote image or configuration file one time, be sure to turn off the remote option (blank out the field on the System Tools page) after the initial download. When a remote boot image is used, the image is transferred directly into memory and is never written to the compact flash.
Wireless Array • history/saved-yyyymmdd-pre-update.conf: history/saved-yyyymmdd-post-update.conf: Two files are automatically saved for a software upgrade or for a license change (including the setting values from just before the upgrade/change was performed, and the initial values afterward. The filename includes the date. • history/saved-yyyymmdd-auto.conf: Each time you use the Save changes to flash button, an “auto” file is saved with the settings current at that time.

Wireless Array To enter a command, simply type it in. The command is echoed and output is shown in the normal way — that is, the same way it would be if you were using the CLI directly. You may use the extra scroll bar inside the right edge of the window to scroll through your output. If output runs past the right edge of the screen, there is also a horizontal scroll bar at the bottom of the page.
Wireless Array API Documentation Arrays provide an API interface conforming to the RESTful API model. Developers may use this read-only API to read status, statistics, and settings from the Array. The interactive API Documentation page provides documentation for the API. You may use the Array’s API for purposes such as integrating with third party applications or creating your own applications for network monitoring and analysis.
Wireless Array Status/Settings The RESTful API on the Array is broken into these two main headings: status and settings. Each is a node that may be clicked to expand or collapse the list of corresponding API requests available on the Array. Since this is a read-only API, the list consists exclusively of GET operations. The figure below shows part of the list displayed by clicking /settings. Click again to collapse (hide) the list. Figure 187.

Wireless Array The Command Line Interface If you are a Cloud XMS customer, then Arrays are managed via the cloud, and local Array management interfaces are inaccessible. If the Array is being managed by your own server for XMS Release 6.5 or above, and if the Array has been assigned to a named network in XMS, you will be restricted to read-only Array access. See “XMS-Managed Arrays Restrict Local Management” on page 78.
Wireless Array Establishing a Secure Shell (SSH) Connection Use this procedure to initialize the system and log in to the Command Line Interface (CLI) via a Secure Shell (SSH) utility, such as PuTTY. When connecting to the unit’s Command Line Interface over a network connection, you must use a Secure SHell version 2 (SSH-2) utility. Make sure that your SSH utility is set up to use SSH-2. 1. 2. Start your SSH session and communicate with the Array via its IP address.
Wireless Array Getting Started with the CLI The root command prompt (Root Command Prompt) is the first prompt you see after logging in to the CLI. If you are at a level other than the root command prompt you can return to this prompt at any time by using the exit command to step back through each command prompt level. The root command prompt you see in the CLI window is determined by the host name you assigned to your Array.
Wireless Array ? Command This command is available at any prompt and provides either FULL or PARTIAL help. Using the ? (question mark) command when you are ready to enter an argument will display all the possible arguments (full help). Partial help is provided when you enter an abbreviated argument and you want to know what arguments will match your input. Figure 196.
Wireless Array Top Level Commands This section offers an at-a-glance view of all top level commands — organized alphabetically.

Wireless Array Appendix B: FAQ and Special Topics This appendix provides valuable support information that can help you resolve technical difficulties. Before contacting Xirrus, review all topics below and try to determine if your problem resides with the Wireless Array or your network infrastructure.
Wireless Array The Wireless Array should only be used with Wi-Fi certified client devices. See Also Contact Information Multiple SSIDs Security VLAN Support Frequently Asked Questions This section answers some of the most frequently asked questions, organized by functional area. Multiple SSIDs Q. What Are BSSIDs and SSIDs? A. BSSID (Basic Service Set Identifier) refers to an individual access point radio and its associated clients.
Wireless Array Q. What would I use SSIDs for? A. The creation of different wireless network names allows system administrators to separate types of users with different requirements. The following policies can be tied to an SSID: Minimum security required to join this SSID. The wireless Quality of Service (QoS) desired for this SSID. The wired VLAN associated with this SSID.
Wireless Array 6. If desired (optional), you can select which radios this SSID will not be available on — the default is to make this SSID available on all radios. 7. Click on the Save changes to flash if you wish to make your changes permanent. 8. If you need to edit any of the SSID settings, you can do so from the SSID Management page. See Also Contact Information General Hints and Tips Security SSIDs SSID Management VLAN Support Security Q. How do I know my management session is secure? A.
Wireless Array Configuration auditing Do not change approved configuration settings. The optional Xirrus Management System (XMS) offers powerful management features for small or large Wireless 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.
Wireless Array older wireless clients). Because AES is the strongest encryption standard currently available, it is highly recommended for Enterprise networks. Any of the above encryption modes can be used (and can be used at the same time). TKIP encryption does not support high throughput rates, per the IEEE 802.11n. Q. Which user authentication method should I use? A. User authentication ensures that users are who they say they are.
Wireless Array 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 Wireless Array units? A. When deploying multiple Wireless Arrays, you may need to define which units are part of which wireless network (for example, if you are establishing more than one network).
Wireless Array 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? A.

Wireless Array Array Monitor and Radio Assurance Capabilities All models of the Wireless Array have integrated monitoring capabilities to check that the Array’s radios are functioning correctly, and act as a threat sensor to detect and prevent intrusion from rogue access points. Enabling Monitoring on the Array Any radio may be set to monitor the Array or to be a normal IAP radio.
Wireless Array Radio Assurance The Array is capable of performing continuous, comprehensive tests on its radios to assure that they are operating properly. Testing is enabled using the Radio Assurance Mode setting on the Advanced RF Settings window (Step 2 in “Advanced RF Settings” on page 320). When this mode is enabled, the monitor radio performs loopback tests on the Array. Radio Assurance Mode requires Intrusion Detection to be set to Standard (See Step 1 in “Advanced RF Settings” on page 320).
Wireless Array Radio Assurance Options If the monitor detects a problem with an Array radio as described above, it will take action according to the preference that you have specified in the Radio Assurance Mode setting on the Advanced RF Settings window (see Step 2 page 322): 490 Failure alerts only — The Array will issue alerts in the Syslog, but will not initiate repairs or reboots.
Wireless Array RADIUS Vendor Specific Attribute (VSA) for Xirrus A RADIUS VSA is defined for Xirrus Arrays to control administrator privileges settings for user accounts. The RADIUS VSA is used by Arrays to define the following attribute for administrator accounts: Array administrators — the Xirrus-Admin-Role attribute sets the privilege level for this account. Set the value to the string defined in Privilege Level Name as described in “About Creating Admin Accounts on the RADIUS Server” on page 218.
Wireless Array Location Service Data Formats Xirrus Arrays are able to capture and upload visitor analytics data, acting as a sensor network in addition to providing wireless connectivity. This data is sent to the location server in different formats, based on the type of server. The Location Server URL, Location Customer Key, and Location Period for reporting data are configured under Location settings. See “Location” on page 186 for details.

Wireless Array Glossary of Terms 802.11a A supplement to the IEEE 802.11 WLAN specification that describes radio transmissions at a frequency of 5 GHz and data rates of up to 54 Mbps. 802.11b A supplement to the IEEE 802.11 WLAN specification that describes radio transmissions at a frequency of 2.4 GHz and data rates of up to 11 Mbps. 802.11d A supplement to the Media Access Control (MAC) layer in 802.11 to promote worldwide use of 802.11 WLANs.
Wireless Array authentication The process that a station, device, or user employs to announce its identify to the network which validates it. IEEE 802.11 specifies two forms of authentication, open system and shared key. bandwidth Specifies the amount of the frequency spectrum that is usable for data transfer. In other words, it identifies the maximum data rate a signal can attain on the medium without encountering significant attenuation (loss of power).
Wireless Array cell The basic geographical unit of a cellular communications system. Service coverage of a given area is based on an interlocking network of cells, each with a radio base station (transmitter/receiver) at its center. The size of each cell is determined by the terrain and forecasted number of users. channel A specific portion of the radio spectrum — the channels allotted to one of the wireless networking protocols. For example, 802.11b and 802.11g use 14 channels in the 2.
Wireless Array domain The main name/Internet address of a user's Internet site as registered with the InterNIC organization, which handles domain registration on the Internet. For example, the “domain” address for Xirrus is: http://www.xirrus.com, broken down as follows: http:// represents the Hyper Text Teleprocessing Protocol used by all Web pages. www is a reference to the World Wide Web. xirrus refers to the company. com specifies that the domain belongs to a commercial enterprise.
Wireless Array encryption Any procedure used in cryptography to translate data into a form that can be decrypted and read only by its intended receiver. Fast Ethernet A version of standard Ethernet that runs at 100 Mbps rather than 10 Mbps. FCC (Federal Communications Commission) US wireless regulatory authority. The FCC was established by the Communications Act of 1934 and is charged with regulating Interstate and International communications by radio, television, wire, satellite and cable.
Wireless Array host name The unique name that identifies a computer on a network. On the Internet, the host name is in the form comp.xyz.net. If there is only one Internet site the host name is the same as the domain name. One computer can have more than one host name if it hosts more than one Internet site (for example, home.xyz.net and comp.xyz.net). In this case, comp and home are the host names and xyz.net is the domain name. IPsec A Layer 3 authentication and encryption protocol. Used to secure VPNs.
Wireless Array packet Data sent over a network is broken down into many small pieces — packets — by the Transmission Control Protocol layer of TCP/IP. Each packet contains the address of its destination as well the data. Packets may be sent on any number of routes to their destination, where they are reassembled into the original data. This system is optimal for connectionless networks, such as the Internet, where there are no fixed connections between two locations.
Wireless Array public key In cryptography, one of a pair of keys (one public and one private) that are created with the same algorithm for encrypting and decrypting messages and digital signatures. The public key is made publicly available for encryption and decryption. QoS (Quality of Service) QoS can be used to describe any number of ways in which a network provider prioritizes or guarantees a service's performance.
Wireless Array 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. The Array only allows SSH-2 connections. SSH-2 provides strong authentication and secure communications over insecure channels. SSH-2 protects a network from attacks, such as IP spoofing, IP source routing, and DNS spoofing.
Wireless Array 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.
Wireless Array Wi-Fi Alliance A 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. Wireless Array A high capacity wireless 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.
