It allows a user to fine-tune sys-tem parameters to maximize performance during testing. The differences between IxWLAN and other IP load generators can be summa-rized as follows:•IP-based Load Generators are per-station devices that do not reduce the num-ber of PCs and station NIC cards. You can configure only one IP per station and then send traffic. •IxWLAN allows all stations to be emulated on a single platform and radio chipset, thus reducing the cost and complexity of multiple PCs.IxWLAN creates Virtual Stations (vSTAs) and generates or passes traffic that loads and stress tests Wireless LAN and 802.11 products in terms of:•Frame performance•Number-of-stations capacity•Scalability•WLAN optimizationBecause a single physical 802.11a/b/g emulator emulates multiple vSTAs, it reduces the number of PC and station NIC cards that are needed to test and stage 802.11 products and wireless LANs. As of 6.20 version, IxWLAN is supported by two chassis, the IxWLAN SED and the IxWLAN SED-MR+. IxWLAN SED Figure 1-1 shows the IxWLAN SED chassis.Figure 1-1.

IntroductionWPA/RSN1-6 IxWLAN User Guide, Release 6.201WPA/RSNThis section covers the following topics:•Introduction to WPA/RSN on page 1-6.•EAP Algorithms on page 1-7.•Certificate Files on page 1-7.•Key Hierarchy and Configuration on page 1-7.•Protocol Conformance Testing on page 1-8.Introduction to WPA/RSNIndividual virtual stations can be configured with WPA or RSN authentication. A vSTA can be configured to use either PSK or full 802.1X/EAP authentication. RSN does the strong security of IEEE 802.11i.The strength of WPA/RSN comes from an integrated sequence of operations that encompass 802.1X/EAP authentication and sophisticated key management and encryption techniques. The IxWLAN implementation of WPA/RSN provides the following major opera-tions:•Network security capability determination – This occurs at the 802.11 level and it is communicated through the WPA/RSN information elements in Bea-con, Probe Response, and (Re) Association Requests. The information in these elements includes the authentication method (802.1X or PSK) and the preferred cipher suite (WEP, TKIP, or AES-CCM).•Authentication – For full implementation of WPA/RSN, EAP over 802.1X is used for authentication. Mutual authentication is gained by choosing an EAP type supporting this feature. 802.1X port access control prevents full access to the network until authentication completes. In the case of WPA-PSK or RSN-PSK, mutual authentication between peers (that is, a virtual station and the System Under Test) is achieved through the 4-Way AKMP handshake during which possession and liveness of the correct PSK is confirmed.•Pre-Authentication – IxWLAN also supports pre-authentication, defined in the 802.11i specification as a means of speeding up the roaming process by authenticating with the server before the roam. The pre-authentication is independent of the roam and may be performed with multiple APs.•PMKSA Catching – IxWLAN supports PMKSA catching, defined in the 802.11i specification. PMKSA is the context resulting from a successful IEEE 802.1X authentication exchange between a given vSTA and the Authentication Server.•Key management – The WPA and RSN feature gives a robust key generation/management system that integrates the authentication and data privacy func-tions. The keys are generated after successful authentication and through a subsequent 4-way handshake between the station and System Under Test.

IxWLAN User Guide, Release 6.20 1-7IntroductionWPA/RSN802.1X EAPOL-Key packets are used by WPA and RSN to negotiate and derive pairwise keys used to protect unicast traffic. Group key handshake is used to deliver the group key to each virtual station for protecting multicast and broad-cast class 3 data frames.•Data Privacy (Encryption) – TKIP or AES-CCM (that is, CCMP) is used to replace WEP with more sophisticated cryptographic and security techniques.•Data integrity – TKIP adds a MIC at the end of each plain-text message (MSDU) to ensure that the messages are not being spoofed or replayed. With AES-CCM, the MIC is added to each transmitted MPDU.EAP Algorithms Virtual stations that are configured for WPA or RSN authentication can be con-figured to use the TLS, TTLS, or PEAP EAP algorithms. For TLS, a certificate file and user ID must be specified. The certificate file and user ID are optional for TTLS and PEAP. Additional parameters that may be configured for TTLS and PEAP include: inner algorithm, outer identify, and password. For TTLS and PEAP, authentication proceeds in two stages: Phase 1 (outer) and Phase 2 (inner). The outer identity is used in Phase 1 authentication. The password and inner algorithm are used in Phase 2 authentication. The inner algorithm is normally MS-CHAPv2 for TTLS and EAP-MS-CHAPv2 for PEAP. Certificate Files When using full WPA or RSN (802.1X), valid certificates must be imported into IxWLAN using either the CLI import command or the Available Certificates dialog in the web-based user interface. Key Hierarchy and ConfigurationWPA and RSN use a PMK that is used in derivation of transient keys for encryp-tion and HMAC functions. The IxWLAN WPA/RSN feature supports two core key hierarchies that are defined by the standard:•Pairwise key hierarchy – The pairwise keys used to protect unicast traffic. PTK derived from the PMK.•Group key hierarchy – To protect multicast traffic. GTK derived from the GMK.For full WPA or RSN mode, the PMK is negotiated between the vSTA and an authentication server in a sequence of EAPOL exchanges through the System Under Test. For WPA-PSK or RSN-PSK mode, the PSK (if defined) is used as the PMK. The PSK is manually configured in the vSTA and the System Under Test.IxWLAN 5.0 Limitation – The WPA Specification needs a PSK for each SSID. IxWLAN now supports a single (global) SSID.•IxWLAN supports a PSK per vSTA.•The PSK can be defined using hex notation (64 hex digits) or an ASCII pass-phrase. The ASCII passphrase is converted to a valid 256 bit key.NOTE: IxWLAN imports only certificate files that are in the PKCS#12 format and have been exported with their private key, without strong private key encryption.

IntroductionFiles1-8 IxWLAN User Guide, Release 6.201The 4-way handshake (obtain/install PTK) is processed as follows: •EAPOL-Key Message exchange (four messages)•Verify that a live peer holds the PMK.•Verify that the PMK is current.•Obtain a fresh PTK from the PMK.•Install the Pairwise encryption and integrity keys into IEEE 802.11.•Confirm the installation of the keys.The Group Key Handshake (obtain/install Group Transient Key) is processed using an EAPOL-Key Message exchange (two messages).Protocol Conformance TestingWhen configured with WPA/RSN, IxWLAN tests the following:•802.1X Authentication when configured for full WPA/RSN•802.11i Pre-authentication when configured for full RSN•PMKSA catching results from a successful IEEE 802.1X authentication exchange between a given vSTA and Authentication Server•802.1X Key Management: vSTA/System Under Test 4-way handshake (EAPOL-Key messages), Group Key Handshake (EAPOL-Key messages)•TKIP or AES-CCM (CCMP): Data encryption (unicast and multicast)•WPA or RSN Information Element Conformity: presence in beacons, probe responses; correct AKM suite selector encoding and correct cipher suite selector encodingFilesThe IxWLAN SED and the IxWLAN SED-MR+ chassis have a 256MB “disk-on-a-chip” flash. Excluding boot and firmware images, this allows for 225 MB of file system space to be used for event logging, certificate files, and scenario files.Table 1-2 lists the directories and files that are maintained in the IxWLAN flash file system.Table 1-2. Directories and Files Maintained in the Flash File SystemDirectory Files Description/ (root) IxWLAN Configuration (config), ixwlan.sys, keyfile•config file: The IxWLAN configuration file (config) stores information settings that can be defined using the CLI or the web-based user interface. A backup version (.bak) of this file is also maintained in the unlikely event that the original might become corrupted. IxWLAN loads from this file at power-up/initialization time. It contains basic configuration information.•ixwlan.sys: The ixwlan.sys file is the IxWLAN software image file.

It is a hidden file and is shown only in the direc-tory list in the CLI administrative mode. Do not delete this file or try to access or modify it. The system needs it./Cache Encapsulated certificate file passwordsWhen a certificate file is imported into IxWLAN, a password is needed. This password is encrypted and stored in IxWLAN in the /Cache directory. Note that this directory is visible only in the CLI administrative mode./Certificates Available Certificate filesContains available certificate files that have been imported from the command PC. This directory is available only if the keyfile enables WPA/RSN./Logs Log Files When event logging to a file is enabled, the log files in this directory store records of all IxWLAN activities, with a timestamp indicating when the activity occurred./Scenarios Scenario files After IxWLAN is configured, you may create test scenarios that contain virtual station definitions that are organized into groups. This information is stored in scenario files. The scenario files are created and used by the web-based user interface. The CLI does not create or use scenario files. These files are created when you select Save Scenario to Flash in the web-based user interface./Statistics Virtual Station Statistics Files (for example, Vsta#Stats.dat, VstaMasterStats.dat, VstaAllSumm.dat) Statistics files contain statistics of a test (scenario) run. When a test is complete, a statistics file can be written in the flash file system for each virtual station involved in the test. The Reports section of the web-based user interface can be used to show the contents of these files.Table 1-2.

IntroductionGeneral Usage Notes1-12 IxWLAN User Guide, Release 6.201IXWLAN SED-MR+The IxWLAN SED-MR+ chassis has two LEDs associated with each WLAN port (wport) or Radio (that is, six LEDs in all). During power-up, the left LED blinks briefly, while the right LED goes off solid. After booting, the left LED turns on solid, while the right LED turns off solid. In the idle state (in which no wports are joined and there is no activity), the left LED turns solid on, while the right one goes off solid. In the joined state (in which the wport has joined with an AP), both LEDs blink briefly, yet faster than while power-up. To show network activity (from a joined state), both LEDs blink proportional with the tx/rx bit rates.Radio CharacteristicsIxWLAN conforms to the IEEE 802.11a, 802.11b and 802.11g specifications. In the 802.11a mode, it operates in the 5GHz UNII band. Data is transmitted over a half-duplex radio channel, operating at up to 54 Mb/s using OFDM. In the 802.11b mode, IxWLAN operates in the 2.4 GHz band and sends data at up to 11 Mb/s. In the 802.11g mode, IxWLAN operates in the 2.4 GHz band, using OFDM at rates of up to 54 Mb/s.Antennas The IxWLAN SED chassis provides two antennas, one each for the 802.11 b/g mode and 802.11a mode. On the IxWLAN SED-MR+ chassis, there is a single antenna for each of the 3 independent wports, each handling 802.11b/g, as well as 802.11a mode.The antennas can be swiveled 180 degrees and angled up or down to optimize signal gain. Please note that the antennas are shipped separately and need to be attached to the chassis. For more details about the installation, please refer to Chapter 2, Installation.General Usage Notes1. Intermixing of CLI, Web-Based User Interface, and SDK operations is not supported. 2. You can access IxWLAN using the serial port or an Ethernet connection. For a serial port connection, the serial port must be configured as follows: 115200 baud, 8 data bits, no parity, 1 stop bit, no flow control. For an Ethernet con-nection, the IxWLAN default IP address is 192.168.0.50. To establish first communications between the command PC and IxWLAN using an Ethernet connection, you must set your PC's IP address and network mask to match this default address (for example, IP address: 192.168.0.2, Netmask: 255.255.255.0). After you establish communications using the default IP address, you can change the IxWLAN and your command PC address to match the addressing scheme used in your network.3. IxWLAN can operate in the 802.11a, 802.11b, or 802.11g wireless mode. The IxWLAN wireless mode affects the devices that you can select as a System Under Test. For example, an IxWLAN that is operating in the 802.11a wire-

IxWLAN User Guide, Release 6.20 1-13IntroductionFeature Key Dependent Parametersless mode does not discover an 802.11b or 802.11g device. Make sure that the wireless mode that you select for IxWLAN is compatible with the device that you want to test. See IxWLAN->Configure IxWLAN on page 4-44 and Virtual Station Setup and Control Commands on page 5-14. 4. The IxWLAN Wireless LAN MAC address defaults to a specific address (typically in the 00:0b:16:xx:xx:xx range). It is a globally unique MAC address that is programmed in to the IxWLAN SED/SED-MR+ chassis. The WLAN base MAC address for each wport (typically in the 00:0b:6b:xx:xx:xx range) and mask (ff:ff:ff:ff:00:00) define the range of MAC addresses that can be assigned to virtual stations configured for that wport. When you spec-ify a starting MAC address for virtual stations, make sure that the address is in the range defined by the WLAN base MAC address and mask for the spec-ified port. See vSTA->Add New vSTA to Group on page 4-39 and IxWLAN->Configure IxWLAN on page 4-44, auth on page 5-17, set wlanmac on page 5-86, get wlanmask on page 5-75 and set wlanmask on page 5-86.5. The default WLAN base MAC address for a given wport can be overridden to prevent conflict with other wireless devices. If you use multiple IxWLANs at your facility, each should have a WLAN MAC with a unique prefix. For example, on the first IxWLAN, use WLAN MAC Address 04:0d:e0:62:23:57 and on the second IxWLAN, use WLAN MAC Address 06:0f:14:62:32:a0.6. Starting with version 6.10 SP2, the requirement that the IP Mask of the IxW-LAN and virtual stations must match the IP subnet addressing scheme for internal mode testing ( used for the external mode) has been removed. The IP address and subnet mask are now per-virtual station attributes and have no interaction with the IP protocol stack used for IxWLAN management.Feature Key Dependent ParametersYour license key is a code sequence that represents your license to use your IxW-LAN. The license key indicates a set of features that are authorized for a specific IxWLAN. Some IxWLAN features are separately licensed. Depending on the license you purchased from Ixia, some IxWLAN features may not be available. Some portions of the user interface may be disabled or enabled, and the appear-ance of dialogs may vary according to your license.

Multiple MonitorsA maximum of four monitors can be defined in each scenario. The tool bar in the top right corner of the monitor area allows you to define a new monitor, delete a monitor, run a paused monitor, pause a running monitor, and clear a monitor’s view. For more information about this section of the page, please refer to Monitors Side Bar on page 4-55.Range Checking/Error MessagesIn the dialogs described later in this chapter, the web-based user interface verifies all entries that need values within a specified range. If a field contains a very large number, do not type commas (,) for values larger than 999 (for example, use 1000 rather than 1,000).If you use an invalid character in a field or specify a value that is not within the allowable range, a dialog opens, as shown in Figure 4-34.Figure 4-34. Range CheckingWhen an Invalid Data dialog opens, click OK and retype a value that is within the allowable range for the field.Using Load Profiles Load Profiles allows you to control the execution of virtual stations: Unsched-uled or Scheduled, as shown in Figure 4-35.

The Web-Based User InterfacevSTA Side Bar4-26 IxWLAN User Guide, Release 6.204vSTA->New Group The New Group dialog allows you to define new groups of virtual stations in a scenario. It is a tabbed dialog with the following sections: vSTA, Traffic, Runt-ime, On Error, and Security. •The Create button allows you to create the group.•The Cancel button allows you to exit the dialog.vSTA->New Group->vSTA The vSTA section of the New IxWLAN Group dialog defines the range of IP and MAC addresses to be used by virtual stations, as shown in Figure 4-37 on page 4-26.The range of MAC addresses specified in this dialog must be within the range of MAC addresses defined by the WLAN Base MAC Address and WLAN MAC Mask in the IxWLAN configuration (see IxWLAN->Configure IxWLAN on page 4-44).Figure 4-37. vSTA SectionGroup Name: Use a group name that helps you identify the devices to be tested (for example, Warehouse, Stock_Room, Ctrl_Tower, Shop_Floor, and so on.). It can be up to 12 characters (a…z, 0…9, and underscore (_)).IxWLAN Address: Shows the IP address of IxWLAN that runs this scenario/test.

IxWLAN User Guide, Release 6.20 4-27The Web-Based User InterfacevSTA Side BarNumber of Virtual Stations: Type the number of virtual stations to create in this scenario group. The maximum number of vSTAs for the IxWLAN SED chassis is 64, and 128 for the IxWLAN SED-MR+ chassis. The default value is 5. If you specify zero virtual stations in this dialog, you must use the Add vSTA to Group dialog to add one or more virtual stations to this group. The Add vSTA to Group dialog uses the default parameters that you set in this group definition.wport: Select the number of the wport (1, 2, or 3). Subsequently, the group is cre-ated on the chosen wport.Starting IP Address: If Sequential or Random is selected in the Address Gener-ation field, type the starting IP address to use for virtual station IP address gener-ation of newly-created virtual stations in this group. Successive virtual station IP addresses are sequentially or randomly generated from this base address.Netmask: Shows the network mask to be used by virtual stations in this group. It cannot be set here. It is global for all virtual stations and an IxWLAN configura-tion parameter.Ending IP Address: If Random is selected in the Address Generation field, type the ending IP address to be used by virtual stations in this group when generating random addresses within a range.Address Generation: Select Sequential, Random, or DHCP from the drop-down list box. The Sequential or Random selections instruct IxWLAN to sequentially or randomly assign IP addresses to newly-created virtual stations. The DHCP mode allows virtual stations to have IP addresses dynamically acquired from a DHCP server on the WLAN network rather than a fixed, configured IP address. If DHCP is selected, IxWLAN initiates lease negotiation if association succeeds for each individual virtual station. Starting MAC Address: Type the starting MAC address to be used for virtual sta-tion MAC address generation of newly-created virtual stations in this group. Suc-cessive virtual station MAC addresses are sequentially or randomly generated from this base address. The starting MAC address must be within the range of MAC addresses defined by the WLAN Base MAC Address and WLAN MAC Mask in IxWLAN configuration (see IxWLAN->Configure IxWLAN on page 4-44).WLAN MAC Mask: The WLAN MAC Mask is a display-only field. It is defined in IxWLAN configuration (see IxWLAN->Configure IxWLAN on page 4-44). It limits the range of MAC addresses that can be detected on the wireless LAN and received by IxWLAN. For example, if the WLAN MAC is set to 00:0b:cd:59:23:44 and the mask is set to ff:ff:ff:ff:00:00, the only MAC addresses that can be detected on the wireless LAN and received by IxWLAN are 00:0b:cd:59:00:00 - 00:0b:cd:59:ff:ff. All other MAC addresses are filtered out. NOTE: If you intend to configure all virtual stations for WPA or RSN authentication, the maximum number of virtual stations is 59.

The Web-Based User InterfacevSTA Side Bar4-28 IxWLAN User Guide, Release 6.204Ending MAC Address: Type the ending MAC address to be used by virtual sta-tions in this group.SSID: Set the SSID to a string. The user can create a vSTA with a SSID. This is an optional field.vSTA->New Group->TrafficThe Traffic section of the New IxWLAN Group dialog defines the type of traffic (Internal/Ping or External/Load Generator) to be used by the virtual station(s), as shown in Figure 4-38.Figure 4-38. vSTA TrafficTraffic Source: Select Internal or External from the list box. In Internal mode, traffic is generated internally by each vSTA using ICMP Echo (Ping) Request/Reply packets. In External mode, packets coming into IxWLAN over 802.3 are mapped to virtual stations by source IP or MAC address and forwarded via 802.11. Packets coming back via 802.11 are remapped to the originating MAC address. Layer 2/Layer 3: If External is selected in the Traffic Source field, select one of these radio buttons to identify the external frames to be captured. If Layer 2 is selected, frames are captured based on the source 802.3 MAC address. If Layer 3 is selected, frames are captured based on the source IP address. For vSTAs con-figured at layer 3, IP and ARP packets generated from this host that contain the

IxWLAN User Guide, Release 6.20 4-29The Web-Based User InterfacevSTA Side Barvirtual station's IP address as a source are translated at the MAC layer to appear as if sourced from the virtual station's MAC address. Target IP Address: Type the target IP address where ICMP Echo (Ping) Requests should be sent. The default IP address (0.0.0.0) shown in this example dialog must be replaced by a valid IP address (for example, 192.168.0.19). Packet Length: Specify the size of the ping data buffer (64…1024). The default is 1024.Count: Specify the total number of pings to be sent: 0…10000 (0=forever).vSTA->New Group->RuntimeThe Runtime section of the New IxWLAN Group dialog allows you to run a vir-tual station’s test multiple times. This is applicable only to internal traffic genera-tion. After each iteration of a test, the state of the virtual station can be set to a base state. A user-defined delay between successive iterations is defined in mil-liseconds (ms). Optionally, any results collected for the virtual station can be cleared at the start of each iteration. Figure 4-39 shows the Runtime section of the New IxWLAN Group dialog.Figure 4-39. vSTA Runtime

The Web-Based User InterfacevSTA Side Bar4-30 IxWLAN User Guide, Release 6.204Number of Iterations: Type the number of times (1…10000) to repeat the virtual station’s task (Ping) or click the Infinite checkbox to continuously iterate indefi-nitely.Iteration Delay: Type the delay (in ms) to be introduced between iterations of the test. It can be set to a value in the 0 to 300000 ms (5 min) range.Before Running Next Iteration->Reset vSTA State to: Select a state from the list box. Each virtual station in this group resets to the selected state (started, authen-ticated, or associated) at the end of each iteration.Before Running Next Iteration->Clear vSTA Results: Select this checkbox to clear test results before successive iterations of the test.RTS Threshold: Type a value in the 1 to 2346 range to define the RTS threshold for the virtual station(s) in this group. Any frame to be transmitted by a virtual station that exceeds the RTS threshold needs a successful RTS/CTS frame exchange before the frame is transmitted. The minimum value (1) effectively needs RTS/CTS for all transmit frames. The maximum value (2346) is the maxi-mum 802.11 frame size and effectively disables RTS.Fragmentation Threshold: Type a value in the 256 to 2346 range to define the fragmentation threshold for the virtual station(s) in this group. The fragmentation threshold limits the number of bytes in any 802.11 frame transmitted by the vir-tual station(s). If this field is set to 2346 (that is, the maximum 802.11 frame size), fragmentation is effectively disabled.Probe before Authentication: An option to select whether to issue a Probe Request in the course of association lifecycle, before the 802.11 authentication.Roam Type: Select Reassociation or Disassociation. Indicates the type of frame exchange to be used for virtual station(s) in this group during a Roam operation: Reassociation (a Reassociation Request is sent to the target AP) or Disassociation (a Disassociation frame is first sent to the origin AP and an Association Request frame is sent to the target AP).vSTA->New Group->On ErrorThe On Error section of the New IxWLAN Group dialog defines whether virtual stations should reconnect to the System Under Test during a test if the system de-authenticates or disassociates a virtual station, as shown in Figure 4-40 on page 4-31.

IxWLAN User Guide, Release 6.20 4-31The Web-Based User InterfacevSTA Side BarFigure 4-40. vSTA ErrorNumber of Retries: Specifies the number of times IxWLAN should issue authen-tication and association requests before failing the operation. It can be a value in the 0 to 10 range. Persist: Click the checkbox to enable or disable persistence. When enabled, vir-tual stations in this group remain persistent (connected) if the System Under Test deauthenticates or disassociates. If IxWLAN loses connection to a System Under Test, persistence allows it to recover and continue the test at the point where it was interrupted. For example, if a virtual station is in a run or associated state and an 802.11 management frame (deauth or disassoc) is sent by the System Under Test and received by IxWLAN, the virtual station tries to return to the state it was in, before the management frame was received. If the virtual station was running a ping test, the ping test continues. If it was in an associated state, the virtual sta-tion reissues the associate request. Auth/Assoc Timeout: Specifies the timeout value (in ms) for authentication and association requests. It can be set to a value in the 250 to 60000 ms (1 min) range.AKMP Timeout: Sets a wait state timer (0…3600 s) for the virtual stations in the group. In situations where the System Under Test does not start or respond dur-ing a 4-way handshake, the affected virtual station may stall in a wait state. The timer can be used to recover the virtual station into an operable state. If the vir-tual station remains in a wait state until this timer expires, it is 802.11 de-authen-ticated and returned to the beginning state. The default value (zero) disables the timer (that is, wait forever).

The Web-Based User InterfacevSTA Side Bar4-32 IxWLAN User Guide, Release 6.204vSTA->New Group->SecurityThis section of the New Group dialog defines whether the virtual station uses security, the type of authentication to be used for authenticating with the System Under Test, and the associated cipher to use. Encryption: Select On or Off from the drop-down list box to enable/disable encryption. Authentication: Select an authentication type: Open System, Shared Key, RSN, RSN-PSK, WPA, or WPA-PSK. If you select RSN or WPA, define user creden-tial parameters in the EAP tab. If you select RSN-PSK or WPA-PSK, define a pre-shared key or passphrase in the PSK tab. Cipher: For Open System or Shared Key Authentication, WEP is the only valid selection. For RSN, RSN-PSK, WPA, and WPA-PSK Authentication, select TKIP or AES-CCM (that is, CCMP cipher mode).Fast Radius: The default value of this attribute is Disabled. When a vSTA is configured for fast RADIUS reconnection and the vSTA has cached the TLS ses-sion information, it tries fast resumption in subsequent 802.1X authentication exchanges by using the session_id and master_key from that cached TLS session.PMKSA Cache: Enables the use of the cached PMKSA information when (re)associating. The default value is Enabled. Each entry in the PMKSA cache contains the BSSID of the corresponding AP, a PMKID, and the Pairwise Master Key (PMK). A PMKSA can be obtained by 802.1X authentication or by pre-authentication.vSTA->New Group->Security WEP TabFor Open System or Shared Key Authentication and WEP Cipher mode, this sec-tion of the New Group dialog allows you to define up to four shared keys, as shown in Figure 4-41 on page 4-33.

IxWLAN User Guide, Release 6.20 4-47The Web-Based User InterfaceIxWLAN Side BarFigure 4-58. Basic Configuration of IxWLANIP Address: Type IxWLAN's new IP address. Use an IP address that is compati-ble with the network addressing scheme at your facility. The default IP address is 192.168.0.50. If you change this field, you must select the Reboot option from the IxWLAN side bar, exit the web-based user interface, and reconnect to IxW-LAN using the new IP address.IP Netmask: Type IxWLAN's network mask. The network mask of IxWLAN must match the IP subnet addressing scheme for internal mode testing (it is not used for external mode). For example, if IxWLAN's IP address is 10.1.40.18 and the system being tested is 10.1.35.17, then the subnet mask is 16 bits or 255.255.0.0.Gateway Address: Type IxWLAN's default gateway IP address. Use an IP address that is compatible with the network addressing scheme at your facility. The default gateway address is 0.0.0.0.

The Web-Based User InterfaceIxWLAN Side Bar4-48 IxWLAN User Guide, Release 6.204IxWLAN->Configure IxWLAN->IxWLAN/RadioThis section of the IxWLAN->Configure IxWLAN dialog defines the wireless mode and data rate of IxWLAN, as shown in Figure 4-59.Figure 4-59. IxWLAN Radio Wireless Mode: Select a wireless mode (11a, 11b, or 11g) from the list box. The items that are available in this list box are different depending on the feature set that you ordered from Ixia. The wireless mode also affects the types of devices that IxWLAN can discover during a scan operation. See General Usage Notes on page 1-12.Data Rate: Select a data rate from the list box. The rates that are available in this list box are different depending on the Wireless Mode selection.MAC: The Wireless LAN MAC address defaults to a specific address (typically in the 00:0b:cd:xx:xx:xx range). It is a globally unique MAC address that is pro-grammed on the IxWLAN SED/SED-MR+ chassis. The address can be changed to any non-broadcast or non-multicast valid MAC address. If you use multiple IxWLANs at your facility, each must have a WLAN MAC whose prefix is unique. For example, on the first IxWLAN, use WLAN MAC Address 04:0d:e0:62:23:57 and on the second IxWLAN, use WLAN MAC Address 06:0f:14:62:32:a0.reset mac: Select this checkbox to reset the WLAN MAC Base Address to its factory default setting.MAC Mask: This address is used in conjunction with the WLAN Base MAC Address for configuration of virtual stations for a specific wport. If for example,

IxWLAN User Guide, Release 6.20 4-49The Web-Based User InterfaceIxWLAN Side Barthe WLAN MAC is set to 00:0b:cd:59:23:44 and the mask is set to ff:ff:ff:ff:00:00, the only MAC addresses that can be detected on WLAN and received by IxWLAN are 00:0b:cd:59:00:00 - 00:0b:cd:59:ff:ff. All other MAC addresses are filtered out. The mask limits the range of MAC addresses that are assigned to virtual stations on a wport. The mask that is specified here displays in the WLAN MAC Mask field when the vSTA tab is selected in the New IxWLAN Group dialog (See vSTA->New Group->vSTA on page 4-26).SSID: Defines a Service Set ID. The SSID is a text string of up to 32 characters. Control characters are not allowed. An SSID is used in Association Requests and in deriving the Pre-Shared Key from the Passphrase, when appropriate. Nor-mally, the SSID supplied in the Beacon from the SUT is used. When the SUT is configured with a hidden SSID (not published in its Beacon), IxWLAN's SSID attribute is used as a default.Multi-Radio Mode: Allows you to select the multi radio mode to be either dynamic or static. Scan at Boot Mode: There are three options for this attribute: Enabled, Disabled, and All Modes. If enabled, a scan of all channels of the IxWLAN Wireless Mode (which can be set by the Wireless Mode list box shown in Figure 4-59 on page 4-48) takes place at boot. If disabled, no scan takes place at boot. If set to All Modes, a scan of all channels in all valid wireless modes (that is, 802.11a/b/g) takes place at boot. The BSS list resulting from the all-mode scan shows BSSs detected across all scanned channels.Background Join: When Background Join is enabled, the unit allows manage-ment frames to be sent before formally joining with the SUT and it automatically conducts the Join in the background while this is happening. When disabled, the system must be explicitly joined with the SUT before any management frames (and thus data frames) can be sent. IxWLAN->Configure IxWLAN->IxWLAN/PowerThis section of the Configure IxWLAN dialog defines the power configuration of IxWLAN, as shown in Figure 4-60 on page 4-50.NOTE: The MAC and MAC Mask are per-wport attributes.

The dBm/mW values in Table 4-1 are applicable only when the country code is US. In other countries, power settings are relative to the maximum transmit power available for the country. If you change the transmit power setting, you must select the Reboot option from the IxWLAN side bar in order for the new transmit power to be recognized and used in IxWLAN.Table 4-1. Transmit Power OptionsPower Management Mode: Select active (always awake) or power save (doze for the specified listen interval) from the list box. See the notes later in this sec-tion.Power Save Listen Interval: Specify the listen interval in terms of the number of beacons (1…100). The default value is 1. Selection Descriptionfull maximum (normal) transmit power (18 dBm/64 mW) half fractional (1/2) transmit power (15 dBm/31.5 mW) quarter fractional (1/4) transmit power (12 dBm/16 mW) eighth fractional (1/8) transmit power (9 dBm/8 mW) minimum minimum transmit power (3 dBm/2 mW)$

IxWLAN User Guide, Release 6.20 4-51The Web-Based User InterfaceIxWLAN Side BarNOTES:When the Power Management mode is set to Active, IxWLAN remains in the awake state at all times. When the Power Management mode is set to Power save, IxWLAN enters a dozing state until awakened by the listen interval. When dozing:•IxWLAN does not accept WLAN frames transmitted to any vSTA. •IxWLAN awakens at each listen interval to receive the next beacon and poll for frames buffered for any vSTA in accordance with the 802.11 Power Man-agement needs. •IxWLAN awakens at DTIM intervals to receive DTIM beacons when buffered broadcast/multicast frames are indicated.While in either state, any WLAN frames to be transmitted from any vSTA may be immediately placed into the Transmit Queue for transmission by the WLAN interface. Any transmission from any vSTA indicates the IxWLAN current Power Management mode.The beacon interval is determined by the System Under Test, usually by some user-configurable parameter. IxWLAN receives beacons sent by the System Under Test. A typical beacon rate is one every 100 Time Units. An 802.11 Time Unit is defined as 1024 ms. So, the beacon rate would be one every 102.4 ms, or about 10 per second. As an example, if the Power Management Mode is set to Power Save and the Power Save Listen Interval is set to 3, IxWLAN wakes up about every 307.2 ms to poll for frames queued in the System Under Test.

The Web-Based User InterfaceIxWLAN Side Bar4-52 IxWLAN User Guide, Release 6.204IxWLAN->Configure IxWLAN->IxWLAN/OtherThis section of the Configure IxWLAN dialog enables/disables the MIC check on received TKIP-encrypted frames, as shown in Figure 4-61.Figure 4-61. IxWLAN OtherMIC Check: Select Enable, Disable, or Spot from this list box. The MIC is an integrity check that is run on all received TKIP data frames and is achieved via the CPU-intensive Michael algorithm. This parameter allows the MIC check to be temporarily disabled or reduced to spot checks (in that case, only every 16th TKIP frame is checked). This applies to receive frames only. The MIC is always calculated for transmit frames when using TKIP.IxWLAN->Reconnect IxWLANReconnect is needed after reboot or if you become disconnected from IxWLAN for any reason.

IxWLAN User Guide, Release 6.20 5-3The Command Line Interface (CLI)CLI Usage Notes•set wlanmac on page 5-85.•reset wlanmac on page 5-77.CLI Usage Notes 1. CLI commands are not case sensitive (for example, set Date is the same as set date). 2. You do not need to type the entire command string to execute a command. Only the number of unique characters needed to identify the command are needed (for example, se da executes the set date command because there are no other CLI commands that begin with se and no other set objects that begin with da).3. Some parameters can be assigned very large values in the 0 to 2,147,483,647 range. Do not type commas (,) for values larger than 999 (for example, use 1000 rather than 1,000).4. It is very important to keep a printed record of configuration parameters. See Configuration Records on page 8-14.User LoginThe IxWLAN logon prompt displays after you successfully establish a connec-tion to IxWLAN. See Chapter 3, First Setup. After you have successfully estab-lished this connection, the CLI prompts you to type a logon name and password. IxWLAN login: AdminPassword: ******The default logon user name is Admin. The default password is IxWLAN. Both entries are case-sensitive (that is, the default user name is Admin, not admin). After you type a valid user name and password, the CLI displays a version ban-ner, the current system time and status, and a CLI prompt (IxWLAN ->).Ixia IxWLAN(tm) Rev 6.20.0.129 EBSystem date & time: FRI APR 20 10:03:31 2007Use the "set date" or "set time" command to adjustIxWLAN(tm) software version 6.20.0.129 EBNumber of wports present ....... 3Multi-radio mode ...............

Except for the number of virtual stations to be configured, values are specified using a “name/value” pair syntax and may be given in any order. autoconf <num> mac <mac_addr> [ip <ip_addr>] [group <grpId>] [wport <integer>] [gateway <ip_addr>] [ipmask <ip_mask>] [csmode persistent|non-persistent] [retry <integer>] [timeout <integer>] [fastradius enabled|disabled] [pmkcache enabled|disabled] [roamtype disassociation|reassociation] [encryption on|off] [keyindex <integer>] [fragmentthreshold <integer>] [rtsthreshold <integer>] [mode external] [layer 2 | 3] | [mode internal] target <ip_addr> [count <integer>] [size <integer>] [dhcpmode off | on | auto] [dhcplease <integer>] [dhcpretry <integer>] [dhcpinterval <integer>] [dhcpoffers <integer>] [dhcpserver <ip_addr>][SSID <string> | <quoted-string> | wildcard] [probe4auth] [authentication open-system|shared-key|rsn-psk|rsn|wpa-psk|wpa] [cipher wep|tkip|aes-ccm] [psk <key>] [passphrase <quoted-phrase>] [eapalgorithm tls|peap|ttls] [certfile <filename>] [userid <string>] [inneralgorithm <inner-auth-id>] [password <inner-auth-passwd>] [outeridentity <outer-auth-ID>] [kmtimeout <integer>]<num>: Specifies the number of virtual stations to be configured. For IxWLAN SED, the maximum number of vSTAs is 64, while IxWLAN SED-MR+ supports a maximum number of 128 vSTAs. If this is not the first autoconf command, new virtual stations are configured starting with the last virtual station and increment-ing for <num>. Default: None.mac <mac_address>: Specifies the base/starting value to be used for virtual sta-tion MAC addresses. This parameter is needed for the first autoconf command and should not be specified for subsequent commands. Default: Last MAC address + 1. The starting MAC address must be within the range of MAC

IxWLAN User Guide, Release 6.20 5-19The Command Line Interface (CLI)Virtual Station Setup and Control Commandsaddresses defined by the WLAN Base MAC Address and WLAN MAC Mask configured for the specified wport (see set wlanmac on page 5-85 and set wlanmask on page 5-85).ip <ip_address>: Specifies the base/starting value to be used for virtual station IP addresses. This parameter is needed for the first autoconf command and should not be specified for subsequent commands. Default: Last IP address + 1.[group <grpId>]: Specifies an optional group ID number (1…128). [wport <integer>]: Creates the virtual station(s) on the specified wport. If this parameter is not specified, the virtual station(s) is/are created on the current wport.[gateway <ip_addr>]: Specifies the IP address of the gateway to be used by the vSTA.[ipmask <ip_mask>]: Specifies the subnet mask to be used by a vSTA.[csmode persistent | non-persistent]: Specifies the connection mode (persistent or non-persistent). [retry <integer>]: Specifies the Authentication/Association retry limit (1…2,147,483,647 or zero (0=no retries)).[timeout <integer>]: Specifies the Authentication/Association timeout, in ms (1…2,147,483,647 or zero (0=immediate timeout)).[fastradius enabled | disabled]: Enables the fast RADIUS reconnection when (re)associating or pre-authenticating. The default is Disabled.[pmkcache enabled | disabled]: Enables the use of cached PMKSA information when (re)associating. The default value of this attribute is Enabled. Cached PMKSA information may be used by virtual stations configured for full RSN (802.11i) authentication.[roamtype disassociation | reassociation]: Selects the roam type. The default value for roamtype is reassociation.[authentication open-system|shared-key|wpa-psk|wpa|rsn|rsn-psk]: Defines the authentication mode: open-system, shared-key, wpa-psk, wpa, rsn, or rsn-psk. [encryption on|off]: Specifies the encryption mode (on or off). [keyindex <integer>]: If encryption is on and authentication is shared-key, this parameter specifies a shared key index number (1…4). These shared keys are defined by the set key command.[cipher wep | tkip | aes-ccm]: Enables WEP, TKIP, or AES-CCM (that is, CCMP) cipher mode. If authentication is open-system or shared-key, wep is the only valid selection.

The Command Line Interface (CLI)Virtual Station Setup and Control Commands5-20 IxWLAN User Guide, Release 6.205[mode internal | external]: If mode is internal, virtual station(s) generate data using Ping (ICMP Echo Request) packets. Each virtual station runs a ping trans-mitter process. The packets contain virtual station IP and MAC source address. If internal is specified, the target parameter must also be specified. If mode is external, data for virtual station(s) is generated by an external host connected to the same LAN as IxWLAN. For vSTAs configured at layer 3, IP and ARP pack-ets generated from this host that contain the virtual station's IP address as a source is translated at the MAC layer to appear as if sourced from the virtual sta-tion's MAC address. Default: internal. [target <ip_address>]: If mode is internal, this parameter specifies the target host's IP address. If mode is internal, this parameter is needed. Default: None.[count <integer>]: If mode is internal, this parameter specifies the number of ping packets to send: 0…2,147,483,647. Default: 1000. [size <integer>]: If mode is internal, this parameter specifies the size of the ping data buffer (64…1024). Default: 1024.[dhcpmode <off | on | auto>]: The DHCP mode allows virtual stations to have IP addresses dynamically acquired from a DHCP server on the network rather than a fixed, configured IP address. If dhcpmode is off, DHCP mode is not active and virtual stations must have a static IP address. If dhcpmode is on, the acquireip command must be used to initiate lease negotiation. If dhcpmode is auto, IxW-LAN automatically starts lease negotiation if the association succeeds. The default value is off. [dhcplease <integer>]: Specifies the lease time that a vSTA is to request.[dhcpretry <integer>]: Specifies the number of times that a vSTA retries a DHCP operation (discover, request) before timing out.[dhcpinterval <integer>]: Specifies the interval between retries.[dhcpoffers <integer>]: Specifies the number of offers to ignore before generat-ing a request.[dhcpserver <ip_addr>]: If set, specifies the DHCP server from which a vSTA is to accept offers (needed when testing with multiple servers).[SSID <string> | <quoted-string> | wildcard]: The SSID is used in (re)association and in computing the pre-shared key from a passphrase for WPA/RSN-PSK. The default value for a vSTA’s SSID is Not Set. If set to Wildcard, the SSID used in the probe and association/re-association requests is the wildcard SSID and the frame contains an SSID Information Element with a length of 0.[probeb4auth]: Directs the autoconfig command to issue the sendprobe com-mand before issuing the auth command.[layer <2 | 3>]: If mode is external, this parameter specifies how the external data stream is captured. If layer is 2, frames are captured based on the source

$IxWLAN User Guide, Release 6.20 5-21The Command Line Interface (CLI)Virtual Station Setup and Control Commands802.3 MAC address. If layer is 3, frames are captured based on the source IP address. The default value is 3.[fragmentthreshold <nBytes>]: <nBytes> can be a value in the 256…2346 range and defines the fragmentation threshold for the virtual station(s) configured by this command. The fragmentation threshold limits the number of bytes in any 802.11 frame transmitted by the vSTA. If <nBytes> is set to 2346 (that is, the maximum 802.11 frame size), fragmentation is effectively disabled. The default value is 2346.[rtsthreshold <nBytes>]: <nBytes> can be a value in the 1…2346 range and defines the RTS threshold for the virtual station(s) configured by this command. Any frame to be transmitted by a vSTA that exceeds the vSTA’s RTS threshold needs a successful RTS/CTS frame exchange before the frame is transmitted. The minimum value (1) effectively needs RTS/CTS for all transmit frames. The maximum value (2346) is the maximum 802.11 frame size and effectively dis-ables RTS. The default value is 2346.[psk <key>]: If authentication is wpa-psk or rsn-psk, this parameter defines a Pre-Shared Key (64 ASCII-hex characters). [passphrase <quoted-passphrase>]: If authentication is wpa-psk or rsn-psk, this parameter defines a passphrase of up to 63 ASCII characters. If the passphrase contains spaces, the passphrase must be specified in double quotes “like so”. To specify a passphrase that contains a double quote, you must escape the double quote “like \” so”. [kmtimeout <integer>]: AKMP Timeout. This parameter sets a wait state timer (0…3600 seconds) for virtual stations. In cases when the System Under Test does not start or respond during a 4-way handshake, the affected virtual station may stall in a wait state. This timer can be used to recover the virtual station into an operable state. If the virtual station remains in a wait state until this timer expires, it is 802.11 de-authenticated and returned to the initialized state. The default value (zero) disables the timer (that is, wait forever). [userid <username>]: If authentication mode is wpa or rsn, this parameter spec-ifies the user ID to be used in the 802.1X exchange. It can be up to 64 characters in the range A…Z, a…z, 0…9, or other legal characters: period (.), dash (-), at-sign (@).[certfile <filename>]: If authentication mode is wpa or rsn, this parameter spec-ifies the filename of the certificate file to be used in the 802.1X exchange. The named certificate file must reside in the Certificates directory in the IxWLAN flash file system. [eapalgorithm tls|peap|ttls]: If authentication mode is rsn or wpa, this parameter specifies an authentication protocol: TLS, PEAP, or TTLS. [inneralgorithm ms-chapv2|eap-ms-chapv2]: If eapalgorithm is peap or ttls, this parameter specifies an inner algorithm for use in Phase 2 authentication. ms-chapv2 is normally used for ttls. eap-ms-chapv2 is normally used for peap.$
