8 Troubleshooting Using a Third-Party Load Generator You may now log on using the factory default logon name (Admin) and password (IxWLAN). Following successful logon, you may use the set login or set password CLI commands to set these parameters as desired. Be sure to record the new settings for future reference. See Configuration Records on page 8-14. Using a Third-Party Load Generator Symptom: Telnet or the Web Client becomes unresponsive during a test or cannot connect at the conclusion of a test.
Troubleshooting Web-Based User Interface Problems Web-Based User Interface Problems The following section describes how to correct some of the more common problems that may occur in the Web-Based User Interface: Security Settings • Security Settings on page 8-3. • Login Error on page 8-4. • Splash Page Error on page 8-5. • IxWLAN Busy or Not Responding on page 8-5. • Loading Files from the Command PC on page 8-7.
8 Troubleshooting Web-Based User Interface Problems • In the Trusted sites dialog, enter the IxWLAN IP address in the Add this Web site to the zone field and click the Add button. Make sure that the Require server verification (https:) for all sites in this zone field is not checked. • Click OK in the Trusted sites dialog. • Click OK in the Internet Options dialog. Startup Error The web-based user interface needs Internet Explorer 6.0 or higher.
Troubleshooting Web-Based User Interface Problems If this error dialog opens, simply click No to continue. This error has no impact on the operation of the web-based user interface or IxWLAN. Splash Page Error The web-based user interface needs pop-ups. If pop-up blocker software is enabled on the command PC, the main page does not display and a message on the splash screen indicates that a pop-up blocker is running, as shown in Figure 8-4.
8 Troubleshooting Web-Based User Interface Problems The status (for example, Online) next to the IxWLAN IP address indicates the current status of IxWLAN with the web-based user interface. This status may intermittently show Busy. If the Busy condition lasts longer than the Polling Timeout specified in the Configure IxWLAN dialog, the status changes to Not Responding and the dialog shown in Figure 8-6 opens. Figure 8-6.
Troubleshooting Missing Key File Loading Files from the Command PC If you try to load a scenario file from the command PC using the web-based user interface, the browser may open the warning dialog shown in Figure 8-8. Figure 8-8. Loading Files from the Command PC If Figure 8-8 opens: • Click Internet Options from the Tools menu in Internet Explorer. • Click the Security tab in the Internet Options dialog. • Click the Trusted sites icon. • Set the Security level for this zone to Low.
8 Troubleshooting Missing Key File NOTE: The web-based user interface does not give any indication of a missing keyfile. When the keyfile is missing, the IxWLAN web server does not respond to the browser. If the keyfile is corrupted or does not exist, or you have requested a feature upgrade, you are asked to enter your unique key or authorization code when you establish a telnet or serial connection and log on to the CLI. Example: C:\>telnet 192.168.0.
Troubleshooting Recovering a Corrupted Firmware File When this message displays, the keyfile is created in flash and this procedure is no longer needed. Recovering a Corrupted Firmware File If you cannot re-establish a telnet connection to the CLI or access the web-based user interface after a new firmware file is loaded, use the supplied serial cable to establish a serial connection between the IxWLAN chassis and the command PC.
8 Troubleshooting Recovering a Corrupted Firmware File Step 2: Connect the serial cable and start a terminal emulation session. • Use the serial cable that is supplied with the unit to connect the IxWLAN chassis to the command PC. • On the command PC, run a terminal emulation program such as HyperTerminal, or some other suitable application. The PC’s COM port must be configured at 115200 baud, 8 data bits, 1 stop bit, and no parity.
Troubleshooting Recovering a Corrupted Firmware File • Press RETURN to end each changed field. Press CTRL-D when finished or press RETURN past any remaining fields. Example: [Boot]: c '.' = clear field; '-' = go to previous field; boot device : processor number : host name : file name : inet on ethernet (e) : inet on backplane (b): host inet (h) : gateway inet (g) : user (u) : ^D = quit ata:0 fei0 0 /ata0a/ixwlan.sys C:\Temp\Ixia\ixwlan.sys 192.168.0.20:ffffff00 192.168.0.101 192.168.0.
8 Troubleshooting Recovering a Corrupted Firmware File Example: IxWLAN login: Admin Password: ** • Use the ls and ls {dirName} commands to examine the available space in the file system. • It may be necessary to delete unused files to create enough available space for the firmware file. You may want to use the ftp command to save an archive before deleting. Use the rm command to delete a file. Step 6: Restore the boot image in flash.
Troubleshooting Recovering a Corrupted Firmware File Step 8: Done! Reboot and resume operations. NOTE: If you have installed firmware version 4.1 or later on an IxWLAN unit that was manufactured before the release of version 4.1, your unit may fail in the bootloader process due to an older boot ROM version. This can be recovered using a boot ROM update procedure that is provided in a separate document that is included with version 4.1+ downloads.

Error and Status Messages Appendix E: E The CLI may show the following error and status messages in response to incorrect or unexpected user actions or WLAN activity. • IxWLAN or Virtual Station Control Messages on page E-1. • WLAN Driver Error Messages on page E-5. • MAC Layer Management Messages on page E-6. • Standard 802.11 WLAN Reason Codes on page E-7. • Standard 802.11 WLAN Status Codes on page E-8.
E IxWLAN or Virtual Station Control Messages Can't resolve gateway's address: The target IP address (internal mode vSTA) is not on the same IP subnet/net as IxWLAN. IxWLAN must forward the Ping frames to a gateway (through which the target may be reached). To forward frames to the gateway, IxWLAN must resolve the gateway's MAC address. This is done by issuing ARP (Address Resolution Protocol) requests for the gateway's MAC address.
IxWLAN or Virtual Station Control Messages vSTA Timed out TLS handshake: The TLS (Transport Layer Security) handshake has been timed out by IxWLAN for a given vSTA. This occurs when IxWLAN is expecting a TLS response from the Authenticator that has not arrived within a specified time period. Internal system error: Requested operation resulted in an unspecified internal error. Invalid message identifier: Internal error—the vSTA control task received a Command message with an invalid message identifier.
E IxWLAN or Virtual Station Control Messages indicate some problem with a certificate, namely, wrong format, invalid content, and so on. The following is an example of the event log output generated by using an invalid certificate: IxWLAN -> assoc vsta 1 IxWLAN -> Error:TLS Error, see event log IxWLAN -> get evlog file a 10/24/2004,2:19:54,245860.029095,42, vSTA 1: SSL error: pk12_read:Error reading PKCS#12 file 10/24/2004,2:19:54,245860.
WLAN Driver Error Messages vStaControl() Err writing NOTIFY into UI's queue: The vSTA control task cannot post a message because the UI task queue is full. This may occur if a web user logs out while IxWLAN is running. vStaControl() Task for NOTIFY no longer exists: The vSTA control task cannot post a message because the UI task is no longer present. This may occur if a telnet user logs out while IxWLAN is running.
E MAC Layer Management Messages MAC Layer Management Messages Invalid parameter: Internal error—an MLME function was invoked with an invalid parameter. MLME Already in BSS: Internal error—a requested MLME function was rejected because IxWLAN is already a member of a BSS. MLME Driver error: Internal error—an MLME function encountered an unspecified error in the device driver. MLME Op not supported: Internal error—an MLME function was invoked that is not supported in the current configuration.
