Wi-Fi Array Configuring the Wi-Fi Array The following topics include procedures for configuring the Array using the product’s embedded Web Management Interface (WMI). Procedures have been organized into functional areas that reflect the flow and content of the WMI.
Wi-Fi Array 172 “Viewing Status on the Wi-Fi Array” on page 123 “Using Tools on the Wi-Fi Array” on page 323 Configuring the Wi-Fi Array
Wi-Fi Array Express Setup The Express Setup procedure allows you to establish global configuration settings that will enable basic Array functionality. Any changes you make in this window will affect all radios. When finished, click on the Apply button to apply the new settings to this session, or click Save to apply your changes and make them permanent. Figure 84.
Wi-Fi Array Procedure for Performing an Express Setup 1. Host Name: Specify a unique host name for this Array. The host name is used to identify the Array on the network. Use a name that will be meaningful within your network environment, up to 64 alphanumeric characters. The default is Xirrus-WiFi-Array. 2. Location Information: Enter a brief but meaningful description that accurately defines the physical location of the Array.
Wi-Fi Array on this port. Choose Yes to allow management of the Array via this Gigabit interface, or choose No to deny all management privileges for this interface. c. 8. Configuration Server Protocol: Choose DHCP to instruct the Array to use DHCP to assign IP addresses to the Array’s Ethernet interfaces, or choose Static if you intend to enter IP addresses manually. If you choose the Static IP option, you must enter the following information: • IP Address: Enter a valid IP address for this Array.
Wi-Fi Array required to use a VPN connection through a secure SSH utility, like PuTTy. • WEP (Wired Equivalent Privacy) — An optional IEEE 802.11 function that offers frame transmission privacy similar to a wired network. WEP generates secret shared encryption keys that both source and destination stations can use to alter frame bits to avoid disclosure to eavesdroppers. • WPA (Wi-Fi Protected Access) — A Wi-Fi Alliance standard that contains a subset of the IEEE 802.
Wi-Fi Array write privileges on the Array (i.e., the new user will be able to change the configuration of the Array). The default admin user is deleted. Note that the Array also offers the option of authenticating administrators using a RADIUS server (see “Admin Management” on page 215)). b. xxxxxxx priority: If you entered a new administration password, confirm the new password here. c. New Admin Password: If desired, enter a new administration password for managing this Array.
Wi-Fi Array d. NTP Primary Server: If you are using NTP, enter the IP address or domain name of the NTP server. e. NTP Secondary Server: Enter the IP address or domain name of an optional secondary NTP server to be used in case the Array is unable to contact the primary server. f. Set Time (hrs:min:sec): If you are not using NTP, check this box if you want to adjust the current system time. When the box is checked, the time fields become active.
Wi-Fi Array 12. Click on the Apply button to apply the new settings to this session, or click Save to apply your changes and make them permanent. Network This is a status-only window that provides a snapshot of the configuration settings currently established for the 10/100 Ethernet 0 interface and the Gigabit 1 and Gigabit 2 interfaces. DNS Settings and CDP Settings (Cisco Discovery Protocol) are summarized as well.
Wi-Fi Array Spanning Tree Status Network Statistics Network Interfaces This window allows you to establish configuration settings for the 10/100 Fast Ethernet interface and the Gigabit 1 and Gigabit 2 interfaces. Figure 87.
Wi-Fi Array Gigabit 2 settings will “mirror” Gigabit 1 settings (except for MAC addresses) and cannot be configured separately. When finished making changes, click on the Apply button to apply the new settings to this session, or click Save to apply your changes and make them permanent. When the status of an Ethernet or Gigabit port changes, a Syslog entry is created describing the change.
Wi-Fi Array 2. LED Indicator: Choose Enabled to allow the LED for this interface to blink with traffic on the port, or choose Disabled to turn the LED off. The LED will still light during the boot sequence, then turn off. This option is only available for the Gigabit interfaces. 3. Allow Management on Interface: Choose Yes to allow management of this Array via the selected network interface, or choose No to deny all management privileges for this interface.
Wi-Fi Array primary link. Gigabit2 is the backup link and is passive. Gigabit2 assumes the IP properties of Gigabit1. If Gigabit 1 fails the Array automatically fails over to Gigabit2. When a failover occurs in this mode, Gigabit2 issues gratuitous ARPs to allow it to substitute for Gigabit1 at Layer 3 as well as Layer 2. See Figure 89 (a). b. Aggregate Traffic from gig1 & gig2 using 802.3ad — The Array sends network traffic across both gigabit ports to increase link speed to the network.
Wi-Fi Array c. Bridge traffic between gig1 & gig2 — Traffic received on Gigabit1 is transmitted by Gigabit2; similarly, traffic received on Gigabit2 is transmitted by Gigabit1. This allows the Array to act as a wired bridge and allows Arrays to be daisy-chained and still maintain wired connectivity. See Figure 90 (c). d. Transmit Traffic on both gig1 & gig2 — Transmits incoming traffic on both Gigabit1 and Gigabit2. Any traffic received on Gigabit1 or Gigabit2 is sent to the onboard processor.
Wi-Fi Array (e) Load balance traffic Gig1 Gig2 Destinations Array load balances outgoing traffic based on source and destination address Switch (f) Mirror traffic Gig1 Gig2 Received wireless traffic is sent to both links Network Analyzer Switch Gig1 Gig2 Traffic from Gig 1 is processed for wireless transmission and copied to Gig 2 Switch Network Analyzer Gig1 Gig2 Traffic from Gig 2 is processed for wireless transmission and copied to Gig 1 Network Analyzer Switch Figure 91.
Wi-Fi Array processor as well as out Gigabit1. This allows a network analyzer to be plugged into one port to capture traffic for troubleshooting, while the other port provides network connectivity for data traffic. See Figure 91 (f). 6. Configuration Server Protocol: Choose DHCP to instruct the Array to use DHCP when assigning IP addresses to the Array, or choose Static IP if you intend to enter IP addresses manually.
Wi-Fi Array DNS Settings This window allows you to establish your DNS (Domain Name System) settings. The Array uses these DNS servers to resolve host names into IP addresses. The Array also registers its own Host Name with these DNS servers, so that others may address the Array using its name rather than its IP address. An option allows you to specify that the Array’s DNS servers will be assigned via a DHCP server on the wired network.
Wi-Fi Array 4. DNS Server 2 and DNS Server 3: Enter the IP address of the secondary and tertiary DNS servers (if required). 5. Use DNS settings assigned by DHCP: If you are using DHCP to assign the Array’s IP address, you may turn this option On. The Array will then obtain its DNS domain and server settings from the network DHCP server that assigns an IP address to the Array, rather than using the DNS Server fields above. You may also configure that DHCP server to assign a host name to the Array. 6.
Wi-Fi Array CDP Settings CDP (Cisco Discovery Protocol) is a layer 2 network protocol used to share information (such as the device manufacturer and model, network capabilities, and IP address) with other directly connected network devices. Wi-Fi Arrays can both advertise their presence by sending CDP announcements, and gather and display information sent by neighbors (see “CDP Neighbors” on page 137). This window allows you to establish your CDP settings.

Wi-Fi Array Services This is a status-only window that allows you to review the current settings and status for services on the Array, including DHCP, SNMP, Syslog, and Network Time Protocol (NTP) services. For example, for the DHCP server, it shows each DHCP pool name, whether the pool is enabled, the IP address range, the gateway address, lease times, and the DNS domain being used.
Wi-Fi Array “SNMP” on page 199 “DHCP Server” on page 202 Time Settings (NTP) This window allows you to manage the Array’s time settings, including synchronizing the Array’s clock with a universal clock from an NTP (Network Time Protocol) server. Synchronizing the Array’s clock with an NTP server ensures that Syslog time-stamping is maintained across all units. Figure 95. Time Settings (Manual Time) Procedure for Managing the Time Settings 192 1.
Wi-Fi Array a. Adjust Time (hrs:min:sec): If you are not using NTP, check this box if you want to adjust the current system time. When the box is checked, you may enter a revised time (hours, minutes, seconds, am/pm) in the corresponding fields. If you don’t want to adjust the current time, this box should be left unchecked (default). b. Adjust Date (month/day/year): If you are not using NTP, check this box if you want to adjust the current system date.
Wi-Fi Array See Also Services SNMP System Log NetFlow This window allows you to enable or disable the sending of NetFlow information to a designated collector. NetFlow is a proprietary but open network protocol developed by Cisco Systems for collecting IP traffic information. When NetFlow is enabled, the Array will send IP flow information (traffic statistics) to the designated collector. NetFlow sends per-flow network traffic information from the Array.
Wi-Fi Array Some features, such as Netflow, are only available if the Array’s license includes the Xirrus Advanced RF Analysis Manager (RAM). If a setting is unavailable (grayed out), then your license does not support the feature. See “About Licensing and Upgrades” on page 325. Procedure for Configuring NetFlow 1. Enable NetFlow: Choose Yes to enable NetFlow functionality, or choose No to disable this feature. 2.
Wi-Fi Array 2. Wi-Fi Tag UDP Port: If you enabled Wi-Fi tagging, enter the port on the Array which the Wi-Fi tagging server will use to query the Array for tagging data. When queried, the Array will send back information on the tags it has observed. For each, the Array sends information such as the MAC address of the tag transmitting device, and the RSSI and noise floor observed. 3. Wi-Fi Tag Channel: If you enabled Wi-Fi tagging, enter the 802.11 channel on which the Array will listen for tags.
Wi-Fi Array Procedure for Configuring Syslog 1. Enable Syslog Server: Choose Yes to enable Syslog functionality, or choose No to disable this feature. 2. Console Logging: If you enabled Syslog, select whether or not to echo Syslog messages to the console as they occur. If you enable console logging, be sure to set the Console Logging level (see Step 7 below). 3.
Wi-Fi Array 7. Syslog Levels: For each of the Syslog destinations, choose your preferred level of Syslog reporting from the pull-down list. Messages with criticality at the selected level and above will be shown. The default level varies depending on the destination. a. Console Logging: For messages to be echoed to the console, the default level is Critical and more serious. This prevents large numbers of non-critical messages from being displayed on the console.
Wi-Fi Array SNMP This window allows you to enable or disable SNMP v2 and SNMP v3 and define the SNMP parameters. SNMP allows remote management of the Array by the Xirrus Management System (XMS) and other SNMP management tools. SNMP v3 was designed to offer much stronger security. You may enable either SNMP version, neither, or both. Complete SNMP details for the Array, including trap descriptions, are found in the Xirrus MIB, available at support.xirrus.
Wi-Fi Array Procedure for Configuring SNMP SNMPv2 Settings 1. Enable SNMPv2: Choose Yes to enable SNMP v2 functionality, or choose No to disable this feature. When used in conjunction with the Xirrus Management System, SNMP v2 (not SNMP v3) must be enabled on each Array to be managed with XMS. The default for this feature is Yes (enabled). 2. SNMP Read-Write Community String: Enter the read-write community string. The default is xirrus. 3.
Wi-Fi Array 10. SNMP Read-Write Privacy Password: Enter the read-write password for privacy (i.e., a key for encryption). The default is xirrus-rw. 11. SNMP Read-Only Username: Enter the read-only user name. This username and password do not allow configuration changes to be made on the Array. The default is xirrus-ro. 12. SNMP Read-Only Authentication Password: Enter the read-only password for authentication (i.e., logging in). The default is xirrus-ro. 13.
Wi-Fi Array System Log Time Settings (NTP) DHCP Server This window allows you to create, enable, modify and delete DHCP (Dynamic Host Configuration Protocol) address pools. DHCP allows the Array to provide wireless clients with IP addresses and other networking information. The DHCP server will not provide DHCP services to the wired side of the network.
Wi-Fi Array Procedure for Configuring the DHCP Server 1. New Internal DHCP Pool: Enter a name for the new DHCP pool, then click on the Create button. The new pool ID is added to the list of available DHCP pools. 2. On: Click this checkbox to make this pool of addresses available, or clear it to disable the pool. 3. Lease Time — Default: This field defines the default DHCP lease time (in seconds). The factory default is 300 seconds, but you can change the default at any time. 4.
Wi-Fi Array 12. Click Apply to apply the new settings to this session, or click Save to apply your changes and make them permanent.
Wi-Fi Array VLANs This is a status-only window that allows you to review the current status of assigned VLANs. A VLAN (Virtual LAN) is comprised of 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.
Wi-Fi Array Virtual Tunnel Server (VTS) Tunneling capability is provided by a Virtual Tunnel Server. You supply the server and deploy it in your network using open-source VTun software, available from vtun.sourceforge.net. To enable the Array to use tunneling for a VLAN, simply enter the IP address, port and secret for the tunnel server as described in Step 10 on page 208. VTun may be configured for a number of different tunnel types, protocols, and encryption types.
Wi-Fi Array VLAN Management This window allows you to assign and configure VLANs. After creating a new VLAN (added to the list of VLANs), you can modify the configuration parameters of an existing VLAN or delete a selected VLAN. Figure 103. VLAN Management The Wi-Fi Array supports dynamic VLAN assignments specified by RADIUS policy settings. When RADIUS sends these assignments, the Array dynamically assigns wireless stations to VLANs as requested. VLAN tags on traffic are passed through the Array (i.
Wi-Fi Array 3. New VLAN Name/Number: Enter a name and number for the new VLAN in this field, then click on the Create button. The new VLAN is added to the list. 4. VLAN Number: Enter a number for this VLAN (1-4094). 5. Management: Check this box to allow management over this VLAN. 6. DHCP: Check this box if you want the DHCP server to assign the IP address, subnet mask and gateway address to the VLAN automatically, otherwise you must go to the next step and assign these parameters manually. 7.
Wi-Fi Array Security This status- only window allows you to review the Array’s security parameters. It includes the assigned network administration accounts, Access Control List (ACL) values, management settings, encryption and authentication protocol settings, and RADIUS configuration settings. There are no configuration options available in this window, but if you are experiencing issues with security, you may want to print this window for your records. Figure 104.

Wi-Fi Array WPA and WPA2 to be used at the same time on the same SSID). Otherwise, if multiple security methods are needed, you must define multiple SSIDs. The encryption mode (WEP, WPA, etc.) is selected in the SSIDs >SSID Management window (see “SSID Management” on page 248). The encryption standard used with WPA or WPA2 (AES or TKIP) is selected in the Security>Global Settings window under WPA Settings (see “Global Settings” on page 231).
Wi-Fi Array this case, enter the MAC address 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. The Wi-Fi Array will accept up to 1,000 ACL entries. PCI DSS or FIPS 140-2 Security — to implement the requirements of these security standards on the Wi-Fi Array, please see Appendix D: Implementing PCI DSS or Appendix E: Implementing FIPS Security.
Wi-Fi Array Using the Array’s Default Certificate Figure 105. Import Xirrus Certificate Authority The Array’s certificate is signed by a Xirrus CA that is customized for your Array and its current host name. By default, browsers will not trust the Array’s certificate. You may import the Xirrus certificate to instruct the browser to trust the Xirrus CA on all future connections to Arrays.
Wi-Fi Array Using an External Certificate Authority If you prefer, you may install a certificate on your Array signed by an outside CA. Why use a certificate from an external CA? The Array’s certificate is used for security when stations attempt to associate to an SSID that has Web Page Redirect enabled. In this case, it is preferable for the Array to present a certificate from an external CA that is likely to be trusted by most browsers.
Wi-Fi Array Procedure for Creating or Modifying Network Administrator Accounts 1. Admin ID: Enter the login name for a new network administrator ID. The length of the ID must be between 5 and 50 characters, inclusive. 2. Read/Write: Choose Read/Write if you want to give this administrator ID full read/write privileges, or choose Read to restrict this user to read only status. In the read only mode, administrators cannot save changes to configurations. 3. User Password: Enter a password for this ID.
Wi-Fi Array may perform any operation except those whose level was set to 4. An error message will be displayed if an operation is attempted without a sufficient privilege level. Figure 107. Admin Privileges Privilege level 0 is read-only. As a minimum, all administrators have permission for read access to all areas of Array configuration. Higher privilege levels may be used to define additional privileges for specific configuration sections.
Wi-Fi Array Procedure for Configuring Admin Privileges 1. Privilege Level Names (optional): You may assign a Name to each Privilege Level. The name may be used to describe the access granted by this level. By default, levels 0 and 1 are named read-only and read-write, respectively, and levels 2 through 7 have the same name as their level number. 2. Privilege Levels: Use this section to assign a Minimum Privilege Level to selected Configuration Sections as desired.
Wi-Fi Array Enforced policies — you may set password rules (e.g., passwords must contain at least one number and be at least 12 characters in length), and you may set expiration times for passwords. Admin RADIUS settings override any local administrator accounts configured on the Admin Management window. If you have Admin RADIUS enabled, all administrator authentication is done via the configured RADIUS servers. The only exception to this is when you are connected via the Console port (using CLI).

Wi-Fi Array Procedure for Configuring Management Control 1. Management Settings: a. Failed login retry period (0-65535 seconds): After three consecutive failing administrator login attempts via ssh or telnet, the administrator’s IP address is denied access to the array for the specified period of time (in seconds). The default is 0. b. Pre-login Banner: Text that you enter here will be displayed above the WMI login prompt. (Figure 110) You may enter up to ??xxx characters??. Figure 110.
Wi-Fi Array c. 3. Port: Enter a value in this field to define the port used by SSH. The default port is 22. Telnet: a. On/Off: Choose On to enable Array management over a Telnet connection, or Off to disable this feature. SSH offers a more secure connection than Telnet, and is recommended over Telnet. b. Connection Timeout 30-100000 (Seconds): Enter a value in this field to define the timeout (in seconds) before your Telnet connection is disconnected.
Wi-Fi Array 6. Management Modes a. Network Assurance: Click the On button to enable this mode. Network assurance checks network connectivity to each server that you configure, such as the NTP server, RADIUS servers, SNMP trap hosts, etc. By proactively identifying network resources that are unavailable, the network manager can be alerted of problems potentially before end-users notice an issue.
Wi-Fi Array the Array in accordance with the PCI DSS requirements. For more information, see “Appendix D: Implementing PCI DSS” on page 455. The pci-audit command checks items such as: c. • Telnet is disabled. • Admin RADIUS is enabled (admin login authentication is via RADIUS server). • An external Syslog server is in use. • All SSIDs must set encryption to WPA or better (which also enforces 802.
Wi-Fi Array start your browser’s Certificate Install Wizard. We recommend that you use this process to install Xirrus as a root authority in your browser. When you assign a Host Name to your Array using the Express Setup window, then the next time you reboot the Array it automatically creates a security certificate for that host name. That certificate uses Xirrus as the signing authority.
Wi-Fi Array a. Download Certificate Signing Request: After creating a certificate signing request (.csr file — Step 9), click the View button to review it. If it is satisfactory, click the name of the .csr file to display the text of the request. You can then copy this text and use it as required by the CA. You may also click on the filename of the .csr file to download it to your local computer. b.
Wi-Fi Array Access Control List This window allows you to enable or disable the use of the global Access Control List (ACL), which controls whether a station with a particular MAC address may associate to the Array. You may create station access control list entries and delete existing entries, and control the type of list. When finished, click on the Save button to save your changes.
Wi-Fi Array Procedure for Configuring Access Control Lists 1. Access Control List Type: Select Disabled to disable use of the Access Control List, or select the ACL type — either Allow List or Deny List. Then click Apply to apply your changes. • 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.

Wi-Fi 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 295. The Array can keep up to 5000 entries in this list. When finished, click on the Save button to save your changes.
Wi-Fi Array Procedure for Establishing Rogue AP Control 1. Rogue BSSID/SSID: Enter the BSSID, SSID, or manufacturer string to match for the new rogue control entry. The Match Only radio buttons specify what to match (e.g., the MAC address, SSID, or manufacturer). You may use the “*” character as a wildcard to match any string at this position. For example, 00:0f:7d:* matches any string that starts with 00:0f:7d:.
Wi-Fi 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.
Wi-Fi Array SSIDs are managed with the following windows: “SSID Management” on page 248 “Active IAPs” on page 259 Understanding SSIDs The SSID (Service Set Identifier) is a unique identifier that wireless networking devices use to establish and maintain wireless connectivity. Multiple access points on a network or sub-network can use the same SSIDs. SSIDs are case-sensitive and can contain up to 32 alphanumeric characters (do not include spaces when defining SSIDs).
Wi-Fi Array As an example, one SSID named accounting might require the highest level of security, while another named guests might have low security requirements. Another example may define an SSID named voice that supports voice over Wireless LAN phones with the highest Quality of Service (QoS) definition. This SSID might also forward traffic to specific VLANs on the wired network.
Wi-Fi Array IEEE802.1p defines eight priority levels for wired networks. Each data packet may be tagged with a priority level, i.e., a user priority tag. Since there are eight possible user priority levels and the Array implements four wireless QoS levels, user priorities are mapped to QoS as described below. End-to-End QoS Handling Wired QoS - Ethernet Port: Ingress: Incoming wired packets are assigned QoS priority based on their SSID and 802.1p tag (if any), as shown in the table below.
Wi-Fi Array 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 802.1p (Wired) 0 (Lowest priority) 0 1 1 2 (Default) 5 3 (Highest priority) 6 Wireless QoS - Radios: Each SSID can be assigned a separate QoS priority (i.e., traffic class) from 0 to 3, where 3 is highest priority and 2 is the default. See “SSID Management” on page 248.
Wi-Fi Array Voice Support The QoS priority implementation on the Array supports voice applications. 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.

Wi-Fi 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 118), then click Create. The SSID name may only consist of the characters A-Z, a-z, 0-9, dash, and underscore. You may create up to 16 SSIDs. SSID List (top of page) 2. SSID: Shows all currently assigned SSIDs. When you create a new SSID, the SSID name appears in this table. Click any SSID in this list to select it. 3.
Wi-Fi Array • 3 — The highest QoS priority setting, normally used to give priority to voice traffic. The QoS setting you define here will prioritize wireless traffic for this SSID over other SSID traffic, as described in “Understanding QoS Priority on the Wi-Fi Array” on page 245. The default value for this field is 2. 8. DHCP Pool: If you want to associate an internal DHCP pool to this SSID, choose the pool from the pull--down list. An internal DHCP pool must be created before it can be assigned.
Wi-Fi Array 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. The encryption standard used with WPA or WPA2 is selected in the Security>Global Settings window (page 231). For an overview of the security options, see “Security Planning” on page 83 and “Understanding Security” on page 210.

Wi-Fi Array SSIDs Understanding QoS Priority on the Wi-Fi Array 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. You may use this window to configure the WDS link IAPs so that only the WDS link SSIDs are active on them. Figure 122.
Wi-Fi Array Per-SSID Access Control List This window allows you to enable or disable the use of the per-SSID Access Control List (ACL), which controls whether a station with a particular MAC address may associate to this SSID. You may create access control list entries and delete existing entries, and control the type of list. When finished, click on the Save button to save your changes.
Wi-Fi Array 3. MAC Address: If you want to add a MAC address to the ACL, enter the new MAC address here, then click on the Add button. The MAC address is added to the ACL. 4. Delete: You may delete selected MAC addresses from this list by checking their Delete buttons, then clicking Apply or Save. 5. Delete All: This button, on the lower left, may be used to delete all the MAC entries in an ACL. 6.
Wi-Fi 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, 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.
Wi-Fi 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.
Wi-Fi Array Understanding QoS Priority on the Wi-Fi 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. When finished, click the Save button to save your changes. Figure 125. Group Management Procedure for Managing Groups 1.
Wi-Fi Array 4. Radius ID: Enter a unique Radius ID for the group, to be used on an external Radius server. When adding a user account to the external server, this Radius ID value should be entered for the user. When the user is authenticated, Radius sends this value to the Array. This tells the Array that the user is a member of the group having this Radius ID. 5. VLAN ID: (Optional) From the pull-down list, select a VLAN for this user’s traffic to use.
Wi-Fi Array 9. L3: (Optional) For this group, check this box to enable fast roaming between IAPs or Arrays at Layer 2 and Layer 3. If the box is not checked, then roaming uses Layer 2 only. You may only select fast roaming at Layers 2 and 3 if this has been selected in Global Settings (IAP). See “Understanding Fast Roaming” on page 270. 10. WPR (Web Page Redirect): (Optional) Check this box if you wish to enable the Web Page Redirect functionality.
Wi-Fi Array To eliminate confusion, we recommend that you configure one set of limits or the other, but not both. 11. Stations: Enter the maximum number of stations allowed on this group. The default is 1536. 12. 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. 13.
Wi-Fi 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 Wi-Fi 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 126.
Wi-Fi Array Figure 127. Source of Channel Setting There are no configuration options in this window, but if you are experiencing problems or simply reviewing the IAP assignments, you may print this window for your records. Click any IAP name to open the associated configuration page. Arrays have a fast roaming feature, allowing them to maintain sessions for applications such as voice, even while users cross boundaries between Arrays.
Wi-Fi Array 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. Mobile Wi-Fi users are likely to cross multiple roaming domains during a single session (especially wireless users of VoIP phones).
Wi-Fi 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.
Wi-Fi Array For all 802.11bg settings, go to “Global Settings .11bg” on page 287. For all 802.11n settings, go to “Global Settings .11n” on page 291. Procedure for Manually Configuring IAPs 1. In the Enabled column, check the box for a corresponding IAP to enable the IAP, or uncheck the box if you want to disable the IAP. 2. In the Band column for 802.11abg(n) radios, select the wireless band for this IAP from the choices available in the pull-down menu, either 2.4GHz or 5 GHz.
Wi-Fi Array • RED — Usage is not recommended, for example, because of overlap with neighboring radios. • YELLOW — The channel has less than optimum separation (some degree of overlap with neighboring radios). • GRAY — The channel is already in use. Select Auto to have the Array dynamically select a channel automatically, based on changes in the Wi-Fi environment. See “Allocating Channels” on page 67 .
Wi-Fi 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 3). 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.
Wi-Fi Array 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. For additional information about cell sizes, go to “Coverage and Capacity Planning” on page 62. 7.

Wi-Fi Array Global Settings (IAP) 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. Figure 129.
Wi-Fi Array Procedure for Configuring Global IAP Settings 278 Some of the features below, such as Load Balancing, are only available if the Array’s license includes the Xirrus Advanced RF Performance Manager (RPM) . If a setting is unavailable (grayed out), then your license does not support the feature. See“About Licensing and Upgrades” on page 325 . 2. IAP Status : Click on the Enable All IAPs this Array, or click on the Disable All IAPs button to enable all IAPs for button to disable all IAPs.
Wi-Fi Array Beacon Configuration 5. 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. 6.
Wi-Fi Array SSIDs — SSID Management window also has a station limit option — Station Limit (page 253). If both station limits are set, both will be enforced. As soon as either limit is reached, no new stations can associate until some other station has terminated its association. 12. Max Phones per IAP: This option allows you to control the maximum number of phones that are allowed per IAP. The default is set to a maximum of 16 but you can reduce this number, as desired.
Wi-Fi Array 16. Broadcast Rates: This changes the rates of broadcast traffic sent by the Array (including beacons). When set to Optimized, each broadcast or multicast packet that is transmitted on each radio is sent at the lowest transmit rate used by any client associated to that radio at that time. This results in each IAP broadcasting at the highest Array TX data rate that can be heard by all associated stations, improving system performance.
Wi-Fi Array 18. ARP Filtering: Address Resolution Protocol finds the MAC address of a device with a given IP address by sending out a broadcast message requesting this information. ARP filtering allows you to reduce the proliferation of ARP messages by restricting how they are forwarded across the network. You may select from the following options for handling ARP requests: • Off: ARP filtering is disabled. ARP requests are broadcast to radios that have stations associated to them.
Wi-Fi Array To enable fast roaming, choose Broadcast or Tunneled, and set additional fast roaming attributes (Step 21). 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). 20.

Wi-Fi 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.
Wi-Fi Array The configuration for WDS is performed on the client Array only, as described in “WDS Client Links” on page 307. No WDS configuration is performed on the host Array. First you will set up a client link, defining the target (host) Array and SSID, 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.
Wi-Fi Array See Also SSID Management Active IAPs WDS Client Link IAP Assignments: WDS Client Links WDS Statistics WDS Client Links This window allows you to set up a maximum of four WDS client links.

Then specify the value to match in the field to the right of the button. Choose Any to use any source address. Check Not to match any address except for the specified address. 12. Destination Address: Define a destination address to match as a filter criterion.
Wi-Fi Array Clusters 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. When you exit cluster mode, configuration commands revert to applying only to the Array to which you are connected.
Wi-Fi Array Cluster Definition 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 142. Cluster Definition Procedure for Managing Cluster Definition 1. New Cluster Name: Enter a name for the new cluster in the field to the left of the Create button, then click Create to add this entry. The new cluster is added to the list in the window.
Wi-Fi Array Cluster Management 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 143. Cluster Management Procedure for Managing Clusters 318 1. Edit Cluster: Select the cluster to display and manage on this window.
Wi-Fi 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. You must use the Apply and Save buttons at the bottom of configuration windows to apply your changes in Cluster Mode, just as you would in normal operation.
Wi-Fi Array 2. Select a WMI window for settings that you wish to configure for the cluster, and proceed to make the desired changes. Click the Apply or Save button when done with that window to apply the changes to all Arrays in the cluster. 3. Proceed to any additional pages where you wish to make changes. 4. Some Status and Statistics windows will present information for all Arrays in the cluster. 5. Click the Save button when done if you wish to save changes on the cluster member Arrays. 6.

Wi-Fi Array Using Tools on the Wi-Fi Array These WMI windows allow you to perform administrative tasks on your Array, such as upgrading software, rebooting, uploading and downloading configuration files, and other utility tasks. Tools are described in the following sections: “System Tools” on page 324 “CLI” on page 336 “Options” on page 337 “Logout” on page 340 This section does not discuss using status or configuration windows.
Wi-Fi Array System Tools 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. Status is shown here Progress is shown here Figure 148.
Wi-Fi Array Some tools, such as Network Tools and Diagnostics, are only available if the Array’s license includes the Xirrus Advanced RF Analysis Manager (RAM). If a tool is unavailable (grayed out), then your license does not support the feature. See “About Licensing and Upgrades” on page 325. About Licensing and Upgrades The Array’s license determines many of the features that are available on the Array.
Wi-Fi Array 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 Wi-Fi Array” on page 100. Alternatively, use the Reboot button to discard any configuration changes which have not been saved since the last reboot. 2. Software Upgrade: This feature upgrades the ArrayOS to a newer version provided by Xirrus.
Wi-Fi Array 3. License Key: If Xirrus provides you with a new license key for your Array, use this field to enter it, then click the Upgrade button to the right. A valid license is required for Array operation, and it controls the features available on the Array. If you upgrade your Array for additional features, you will be provided with a license key to activate those capabilities. If you attempt to enter an invalid key, you will receive an error message and the current key will not be replaced.
Wi-Fi Array 6. The Remote Boot Image or 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.
Wi-Fi Array • history/saved-yyyymmdd-pre-update.conf: history/saved-yyyymmdd-post-update.conf: Two files are saved for an upgrade: the setting values from just before an upgrade was performed, and the initial values afterward. The filename includes the upgrade date. • history/saved-yyyymmdd-auto.conf: Each time you use the Save button, an “auto” file is saved with the settings current at that time. • history/saved-yyyymmdd-pre-reset.conf: history/saved-yyyymmdd-post-reset.
Wi-Fi Array Note that the configuration is automatically saved to a file in a few situations, as described in Step 8 above. Important! When you have initially configured your Array, or have made significant changes to its configuration, we strongly recommend that you save the configuration to a file in order to have a safe backup of your working configuration. 10. Download Current Configuration: Click on the link titled xs_current.
Wi-Fi Array is complete, the filename xs_diagnostic.log will be displayed in blue and provides a link to the newly created log file. Click the link to download this file to the C:\ folder on your local computer. (Figure 149) Click Update to create log Then click this link to save log file to local computer Figure 149. Saving the Diagnostic Log This feature is only used at the request of Customer Support.
Wi-Fi Array Web Page Redirect The Array uses a Perl script and a cascading style sheet to define the default splash/login Web page that the Array delivers for WPR. You may replace these files with files for one or more custom pages of your own. See Step 15 below to view the default files. See Step 14 on page 252 for more information about WPR and how the splash/login page is used. Each SSID that has WPR enabled may have its own page. Custom files for a specific SSID must be named based on the SSID name.
Wi-Fi Array 14. Remove File: Enter the name of the WPR file you want to remove, then click on the Delete button. You can use the List Files button to show you a list of files that have been saved on the Array for WPR. The list is displayed in the Status section at the bottom of the WMI window. You must reboot to make your changes take effect. 15. Download Sample Files: Click on a link to access the corresponding sample WPR files: • wpr.pl — a sample Perl script. • hs.css — a sample cascading style sheet.
Wi-Fi Array The RADIUS Ping command is a simple utility that tests connectivity to a RADIUS server by attempting to log in with the specified Username and Password. When using a RADIUS server, this command allows you to verify that the server configuration is correct and whether a particular Username and Password are set up properly. If a client is having trouble accessing the network, you can quickly determine if there is a basic RADIUS problem by using the RADIUS Ping tool.
Wi-Fi Array 17. IP Address: For Ping or Trace Route, enter the IP address of the target device. 18. Timeout: For Ping or Trace Route, enter a value (in seconds) before the action times out. 19. Execute System Command: Click Execute to start the specified command. Progress of command execution is displayed in the Progress frame. Results are displayed in the Status frame. Progress and Status Frames The Progress frame displays a progress bar for commands such as Software Upgrade and Ping.
Wi-Fi Array CLI The WMI provides this window to allow you to use the Array’s Command Line Interface (CLI). You can enter commands to configure the Array, or display information using show commands. You will not need to log in - you already logged in to the Array when you started the WMI. Figure 154. CLI Window 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.
Wi-Fi Array config-iap. The prompt will indicate the current command mode, for example: My-Array(config-iap) # You can abbreviate a command and it will be executed if you have typed enough of the command to be unambiguous. The command will not auto-complete, however. Only the abbreviated command that you actually typed will be shown. You can type a partial command and press Tab to have the command auto-complete. If the partial command is ambiguous a list of legal endings is displayed.
Wi-Fi Array Procedure for Configuring Options 1. Style: This option allows you to change the appearance and operation of the user interface. Select one of the available styles from the drop-down list. Click the Apply button to view the WMI with the selected style. Note that some styles just change the display appearance (the skin) of WMI, in much the same way as changing the display theme used in Windows 7. Other styles include more extensive changes to the interface. Figure 156.
Wi-Fi Array 2. Refresh Interval in Seconds: Many of the windows in the Status section of the WMI have an Auto Refresh option. You may use this setting to change how often a status or statistics window is refreshed, if its auto refresh option is enabled. Enter the desired number of seconds between refreshes, then click the Apply button. The default refresh interval is 30 seconds. 3.
Wi-Fi Array Logout Click on the Logout button to terminate your session. When the session is terminated, you are presented with the Array’s login window. Figure 157.
Wi-Fi Array The Command Line Interface This section covers the commands and the command structure used by the Wi-Fi Array’s Command Line Interface (CLI), and provides a procedure for establishing a Telnet connection to the Array. Topics discussed include: “Establishing a Secure Shell (SSH) Connection” on page 341. “Getting Started with the CLI” on page 343. “Top Level Commands” on page 346. “Configuration Commands” on page 355. “Sample Configuration Tasks” on page 389.
Wi-Fi Array network administrator assign a reserved address to the Array for ease of access in the future. 2. • If the network does not use DHCP, use the factory default address 10.0.2.1 to access either the Gigabit 1 or Gigabit 2 Ethernet port. You may need to change the IP address of the port on your computer that is connected to the Array — change that port’s IP address so that it is on the same 10.0.2.xx subnet as the Array port.
Wi-Fi 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.
Wi-Fi Array The help command is only available at the root command prompt. Initiating this command generates a window that provides information about the types of help that are available with the CLI. Figure 159.
Wi-Fi 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 160.

Wi-Fi Array Appendix C: Technical Support This appendix provides valuable support information that can help you resolve technical difficulties. Before contacting Xirrus, review all topics below and try to determine if your problem resides with the Wi-Fi Array or your network infrastructure.
Wi-Fi Array If you are deploying multiple units, the Array should be oriented so that the abg(n)2 radio is oriented in the direction of the least required coverage, because when in monitor mode the abg(n)2 radio does not function as an AP servicing stations. The Wi-Fi Array should only be used with Wi-Fi certified client devices.
Wi-Fi Array Q. What would I use SSIDs for? A. The creation of different wireless network names allows system administrators to separate types of users with different requirements. The following policies can be tied to an SSID: Minimum security required to join this SSID. The wireless Quality of Service (QoS) desired for this SSID. The wired VLAN associated with this SSID.
Wi-Fi Array 6. If desired (optional), you can select which radios this SSID will not be available on — the default is to make this SSID available on all radios. 7. Click on the Apply button to apply your changes to this session. 8. Click on the Save button to save your changes. 9. If you need to edit any of the SSID settings, you can do so from the SSID Management page. See Also Contact Information General Hints and Tips Security SSIDs SSID Management VLAN Support Security Q.
Wi-Fi Array SSH versus Telnet Be aware that Telnet is not secure over network connections and should be used only with a direct serial port connection. When connecting to the unit’s Command Line Interface over a network connection, you must use a Secure SHell (SSH) utility. The most commonly used freeware providing SSH tools is PuTTY. The Array only allows SSH-2 connections, so your SSH utility must be set up to use SSH-2. Configuration auditing Do not change approved configuration settings.
Wi-Fi Array TKIP solves security issues with WEP. It also allows you to establish encryption keys on a per-user-basis, with key rotation for added security. In addition, TKIP provides Message Integrity Check (MIC) functionality and prevents active attacks on the wireless network. AES is the strongest encryption standard and is used by government agencies; however, old legacy hardware may not be capable of supporting the AES mode (it probably won’t work on older wireless clients).
Wi-Fi Array (provided by the Wi-Fi Array) or external. An external RADIUS server offers more functionality and is recommended for large Enterprise deployments. When using this method, user names and passwords must be entered into the RADIUS server for user authentication. MAC Address ACLs (Access Control Lists) MAC address ACLs provide a list of client adapter MAC addresses that are allowed or denied access to the wireless network.
Wi-Fi Array VLAN Support Q. What Are VLANs? A. VLANs (Virtual Local Area Networks) are a logical grouping of network devices that share a common network broadcast domain. Members of a particular VLAN can be on any segment of the physical network but logically only members of a particular VLAN can see each other. VLANs are defined and implemented using the wired network switches that are VLAN capable. Packets are tagged for transmission on a particular VLAN according to the IEEE 802.
Wi-Fi Array As an example, to provide guest user access an SSID of guest might be created. This SSID could be mapped to a wired VLAN that segregates unknown users from the rest of the wired network and restricts them to Internet access only. Wireless users could then associate to the wireless network via the guest SSID and obtain access to the Internet through the selected VLAN, but would be unable to access other privileged network resources.
Wi-Fi Array Array Monitor and Radio Assurance Capabilities All models of the Wi-Fi Array have a monitor radio, abg(n)2, that checks that the Array’s radios are functioning correctly, and acts as a dedicated threat sensor to detect and prevent intrusion from rogue access points. Enabling Monitoring on the Array IAP abg(n)2 may be set to monitor the Array or to be a normal IAP radio.
Wi-Fi 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 6 in “Advanced RF Settings” on page 294). When this mode is enabled, IAP abg(n)2 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 294).
Wi-Fi 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 6 page 297): 442 Failure alerts only — The Array will issue alerts in the Syslog, but will not initiate repairs or reboots.
Wi-Fi Array RADIUS Vendor Specific Attributes (VSAs) for Xirrus A number of RADIUS VSAs are defined for Xirrus Arrays. These control administrator privileges and a number of settings for user accounts, such as QoS, roaming, VLAN, etc. The RADIUS VSAs are used by Arrays to define selected attributes for the following account types: Array administrators — the Xirrus-Admin-Role attribute sets the privilege level for this account.

Wi-Fi 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.
Wi-Fi Array authentication The process that a station, device, or user employs to announce its identify to the network which validates it. IEEE 802.11 specifies two forms of authentication, open system and shared key. bandwidth Specifies the amount of the frequency spectrum that is usable for data transfer. In other words, it identifies the maximum data rate a signal can attain on the medium without encountering significant attenuation (loss of power).
Wi-Fi Array cell The basic geographical unit of a cellular communications system. Service coverage of a given area is based on an interlocking network of cells, each with a radio base station (transmitter/receiver) at its center. The size of each cell is determined by the terrain and forecasted number of users. channel A specific portion of the radio spectrum — the channels allotted to one of the wireless networking protocols. For example, 802.11b and 802.11g use 14 channels in the 2.
Wi-Fi Array DNS (Domain Name System) A system that maps meaningful domain names with complex numeric IP addresses. DNS is actually a separate network — if one DNS server cannot translate a domain name, it will ask a second or third until a server is found with the correct IP address. domain The main name/Internet address of a user's Internet site as registered with the InterNIC organization, which handles domain registration on the Internet. For example, the “domain” address for Xirrus is: http://www.
Wi-Fi Array EDCF (Enhanced Distributed Coordinator Function) A QoS extension which uses the same contention-based access mechanism as current devices but adds “offset contention windows” that separate high priority packets from low priority packets (by assigning a larger random backoff window to lower priorities than to higher priorities). The result is “statistical priority,” where high-priority packets usually are transmitted before low-priority packets.
Wi-Fi Array Gigabit 2 The secondary Gigabit Ethernet interface. See also, Gigabit Ethernet. Gigabit Ethernet The newest version of Ethernet, with data transfer rates of 1 Gigabit (1,000 Mbps). Group A user group, created to define a set of attributes (such as VLAN, traffic limits, and Web Page Redirect) and privileges (such as fast roaming) that apply to all users that are members of the group. This allows a uniform configuration to be easily applied to multiple user accounts.
Wi-Fi Array MTU (Maximum Transmission Unit) The largest physical packet size — measured in bytes — that a network can transmit. Any messages larger than the MTU are divided into smaller packets before being sent. Every network has a different MTU, which is set by the network administrator. Ideally, you want the MTU to be the same as the smallest MTU of all the networks between your machine and a message's final destination.
Wi-Fi Array preamble Preamble (sometimes called a header) is a section of data at the head of a packet that contains information that the access point and client devices need when sending and receiving packets. PLCP Has two structures, a long and a short preamble. All compliant 802.11b systems have to support the long preamble.
Wi-Fi Array SDMA (Spatial Division Multiple Access) A wireless communications mode that optimizes the use of the radio spectrum and minimizes cost by taking advantage of the directional properties of antennas. The antennas are highly directional, allowing duplicate frequencies to be used for multiple zones. SNMP (Simple Network Management Protocol) A standard protocol that regulates network management over the Internet. SNTP (Simple Network Time Protocol) A simplified version of NTP.
Wi-Fi Array subnet mask A mask used to determine what subnet an IP address belongs to. An IP address has two components: (1) the network address and (2) the host address. For example, consider the IP address 150.215.017.009. Assuming this is part of a Class B network, the first two numbers (150.215) represent the Class B network address, and the second two numbers (017.009) identify a particular host on this network.
Wi-Fi Array multiple switches from different vendors. This interoperability and traffic containment across different switches is the result of a switch's ability to use and recognize 802.1Q tag headers — called VLAN tagging. Switches that implement 802.1Q tagging add this tag header to the frame directly after the destination and source MAC addresses. The tag header indicates: 1. That the packet has a tag. 2. Whether the packet should have priority over other packets. 3.
Wi-Fi Array WPA2 (Wi-Fi Protected Access 2) WPA2 is the follow-on security method to WPA for wireless networks and provides stronger data protection and network access control. It offers Enterprise and consumer Wi-Fi users with a high level of assurance that only authorized users can access their wireless networks. Like WPA, WPA2 is designed to secure all versions of 802.11 devices, including 802.11a, 802.11b, 802.11g, and 802.11n, multi-band and multi-mode.
