EmulationEngine 11a/b/g User's Guide Rev #/Date: 2.0.0 Beta/07.17.03 7-1 CHAPTER 7: Event Logging Overview During normal operation, the EmulationEngine processes and can log various types of events. When an event is logged, a record of the event is stored for future analysis. The event record includes a timestamp, an indicator of the type of event that occurred, and a limited amount of data to describe the event. Event logging is controlled on three levels: 1) master enable (controlled by set evlog enable/disable) 2) verbosity level (controlled by set evlog level <level>) 3) module enable (controlled by set evlog module <module name> enable/disable) 1) The master enable controls whether event logging occurs at all. The master control is independent of other filters. If "set evlog disable" is used, enabling event logging for a particular module has no effect. 2) The verbosity level sets an “importance” threshold for events: at lower verbosity, only more “important” events are logged; at higher verbosity, less important events may also be logged. 3) Each event is processed by a given module or process within the EmulationEngine. The various processes of the system can be individually enabled for event logging. The event logging function stores event records into a buffer area in memory. The log buffer is a circular buffer that can hold 512 event records. The "get evlog buffer" command can be used to display the contents of the buffer at any time. Event data can also be written to a log file in Flash. When writing to a file is enabled by the "set evlog file enable" command, the log buffer is flushed to a file every 30 seconds or every time it wraps at the 512-record limit (which ever comes first). There are two log files, A and B. The EmulationEngine will alternate between the two files so that at least one full file is available at any given time. Each log file can store up to 4,000 event records. You can display the records stored in either file using the "get evlog file A" and "get evlog file B" CLI commands. Event Record Format Event records are printed in the following format: [header]: [message] [optional parameters] Example: 12/27/2002,9:59:57,2296.320226,11396: RX: ok pDesc 0x9326c0 hwStatus 01cd803c:0be20203 numRxDesc 9643712
Communication Machinery Corporation (CMC) 7-2 Rev #/Date: 2.0.0 Beta/07.17.03 where: [header] is a standard header consisting of a timestamp, microsecond clock reference and sequence number (e.g.: 12/27/2002,9:59:57,2296.320226,11396) timestamp = 12/27/2002,9:59:57 (time the event occurred, taken from the system clock) microsecond clock reference = 2296.320226 (in seconds, resolution to 1 microsecond, not sync’ed to timestamp) sequence number = a sequential number assigned to each record (e.g., 11396; next event would be 11397, 11398, etc.) [message] is very brief text string (typically < 15-20 characters) indicating the type of event that occurred (e.g.: RX: ok indicates a valid 802.11 frame received without error). [optional parameters] describe the specific circumstances of this particular occurrence of the event. It can be up to four 32-bit parameters. Example: pDesc 0x9326c0 hwStatus 01cd803c:0be20203 numRxDesc 9643712. CLI Commands The following CLI commands control event logging: set evlog enable/disable: This is the master control to enable or disable event logging (i.e., to the event log buffer in RAM). The default is enabled. set evlog level <level>: This command sets the verbosity level (0/critical, 1/low, 2/medium, or 3/high) for event logging. The default is critical. set evlog module <module> enable/disable: This command enables or disables logging events from the specified module or process: EmulationEngine control events, virtual station control events, WLAN transmit and receive events, and User Interface events. By default, the following processes are enabled for event logging: EmulationEngine control events and virtual station control events. The following processes are disabled for event logging: WLAN transmit and receive events and User Interface events. set evlog console enable/disable: This command enables or disables logging directly to the console. The default is disabled. set evlog file enable/disable: This command enables or disables recording logged events to file. The default is disabled. get evlog settings: This command shows the current event log control settings.
EmulationEngine 11a/b/g User's Guide Rev #/Date: 2.0.0 Beta/07.17.03 7-3 get evlog buffer [n] – This command prints the last n events logged to the log buffer in memory. If [n] is omitted or zero, all events currently in the log buffer will be displayed. get evlog file A/B <startRec#> <count>: This command prints event records in log file A or B. If no starting record number <startRec#> is given, records are displayed starting with the first record in the file. If no count of records is given, all records are displayed. You can also use "?" to display the number of records in the file. clear evlog file A/B: This command clears all event records from log file A or B clear evlog buffer: This command clears all event records from the log buffer. save evlog: This command flushes all records from the log buffer to the log file, even if log to file is not enabled. NOTE: Event log control settings are not permanent. They are not saved with other configuration controls. They must be entered following startup as desired to change event log operation from the default settings indicated above. The Web-Based User Interface You can configure and display the event log by selecting the Logging tab in the web-based user interface side bar. See the "Event Log Side Bar" in Chapter 5 for details.

EmulationEngine 11a/b/g User's Guide Rev #/Date: 2.0.0 Beta/07.17.03 9-1 CHAPTER 9: Troubleshooting Login Name and/or Password Recovery If configuration records for your EmulationEngine are lost and you do not remember its user name or password, it may not be possible to log in to the device. If this should happen, a special login sequence will direct the EmulationEngine to reset the login name and password to their factory defaults.  Open a telnet connection to the device  At the login prompt, type RESET in response to the EE login prompt and FACTORY in response to the Password prompt. These are both case sensitive. Example: EE login: RESET Password: ******* In response to this sequence, the EmulationEngine will reset both the login username and the login password to their factory defaults (User Name: Admin, Password: EE). A new configuration file with the reset login and password will be written to the Flash file system, and the EmulationEngine will issue a new login prompt. No other configuration parameters are affected by this operation. You may now log in using the factory default login name (Admin) and password (EE). Following successful login, 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. 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. Possible Problems:  If your Load Generator exceeds the maximum 802.3 rate specified in the EmulationEngine Specifications during a test: 1) Telnet and/or the Web Client may not be able to establish a new connection. 2) If connected, Telnet and/or the Web Client may lose connectivity to the EmulationEngine.  If Telnet or the Web Client become unresponsive during a test or cannot connect at the conclusion of a test, make sure your Load Generator is not responding to ARP requests that are targeted to the EmulationEngine address. If this occurs, the ARP request transmitted from the PC Client (running telnet) or the Web Client for the purpose of obtaining the MAC address of an IP address, will respond with the Load Generator's MAC address instead of the EmulationEngine's MAC address. All data sourced from the PC
Communication Machinery Corporation (CMC) 9-2 Rev #/Date: 2.0.0 Beta/07.17.03 client would incorrectly be destined to the Load Generator instead of the EmulationEngine. Web-Based User Interface Login Error If you are running a personal firewall product (e.g., ZoneAlarm, McAfee's software firewall, etc.) on the command PC, the following error dialog may be displayed by your browser immediately following successful log-in to the EmulationEngine web server: If this error dialog is displayed, just click the No button to continue. This error has not impact on the operation of the web-based user interface or the EmulationEngine. Hardware Installation/LEDs Power LED: When you apply power to the EmulationEngine, the power LED (the left-most LED facing the front of the unit) should flash momentarily and then light ON (solid). If this does not occur, check the power cable connection and/or the power outlet where the power supply is installed. If power is being supplied to the unit and the Power LED remains off, it may indicate that the EmulationEngine’s software image file (EE22.SYS) cannot be loaded into flash (i.e., corrupted or does not exist). Ethernet LED: When you attach the Ethernet cable between the command PC and the EmulationEngine, the Ethernet link LED (the middle LED) should flash momentarily and then light ON (solid). This should occur if you are attaching directly to the EmulationEngine using a cross-over cable or through a hub/switch using a straight cable. If the LED remains OFF, check the cable connections. If the LED remains OFF, one or more of the following problems may exist:  Incorrect or defective cable  Defective hub/switch  Using the wrong port on a hub/switch (i.e., uplink port instead of 10/100 port) EmulationEngine Busy or Not Responding The status bar in the top-right corner of the web-based user interface main page shows the status of the EmulationEngine with the System Under Test.
EmulationEngine 11a/b/g User's Guide Rev #/Date: 2.0.0 Beta/07.17.03 9-3 The status (e.g., Online) next to the EmulationEngine IP address indicates the current status of EmulationEngine with with the web-based user interface. This status may intermittently display “Busy”. If the Busy condition lasts longer than the Polling Timeout specified in the Configure EmulationEngine dialog, the status will change to Not Responding and the following dialog will be displayed: When this dialog is displayed, the user interface will disable all actions until the EmulationEngine starts responding again. When you click “OK” to dismiss this dialog, the EmulationEngine/System connection status in the status bar will display “Offline”.  If Busy is frequently shown in the status bar, increase the value of the Polling Interval in the Configure EmulationEngine dialog (see EE->Configure EE).  If the “EmulationEngine Not Responding” dialog is displayed frequently, increase the value of the EE Polling Timeout in the Configure EmulationEngine dialog (see EE->Configure EE).  If the “EmulationEngine Not Responding” dialog continues to be displayed, check the cable connections between the command PC and the EmulationEngine.  You may also establish a telnet connection to access and log in to the CLI to verify that the EmulationEngine is or is not responding. When Not Responding status is cleared and the web-based user interface receives a response from the EmulationEngine, the following dialog will be displayed:
Communication Machinery Corporation (CMC) 9-4 Rev #/Date: 2.0.0 Beta/07.17.03 Loading Files from the Command PC If you attempt to load a scenario file from the command PC using the web-based user interface, the browser may display the following warning dialog: Click “OK” to continue. Missing Key File The EmulationEngine is offered in four configurations:  EmulationEngine 11a: Supports IEEE 802.11a only.  EmulationEngine 11b: Supports IEEE 802.11b only.  EmulationEngine 11a/11b: Supports IEEE 802.11a and 802.11b.  EmulationEngine 11a/b/g: Supports IEEE 802.11a, 802.11b, and 802.11g. Each configuration is shipped with a unique feature key that is stored in the EmulationEngine’s flash file system. If the keyfile does not exist or is corrupted or you have requested a feature upgrade, the CLI will prompt you to enter your authorization code in order to create the keyfile. There are only two conditions where the authorization code must be entered. 1) Feature Upgrades 2) Corrupted or non-existent keyfile NOTE: The web-based user interface does not provide any indication of a missing keyfile. When the keyfile is missing, the EmulationEngine’s web server will not respond to the browser. If the keyfile has been corrupted or does not exist or you have requested a feature upgrade, you will be prompted to enter your unique key/authorization code when you establish a telnet or serial connection and log in to the CLI.

EmulationEngine 11a/b/g User's Guide Rev #/Date: 2.0.0 Beta/07.17.03 B-1 APPENDIX B: Software Upgrades Complete the following steps to load a new software file into the EmulationEngine’s flash file system: 1) If you are already logged in to the CLI, type reboot to return the EmulationEngine to a known state: reboot 2) Use Telnet to log back in to the CLI: telnet 192.168.0.50 EE login: Admin Password: EE EmulationEngine Rev x.x CMC_EE -> This step uses the EmulationEngine’s default IP address (192.168.0.50). If you have changed the IP address, use the address you previously configured in the EmulationEngine. 3) Use the "ls" command to verify that there is enough space in the flash file system for the new software. CMC_EE -> ls 4) Compare the bytes free count to the size of the software file you want to download. If there is not enough space, use the "rm" command to remove one or more files from flash. DO NOT remove the keyfile. CMC_EE -> rm <file_name> 5) You must have an FTP server running in order to complete this step. In the CLI, enter the "ftp" command and the command PC’s IP address. Example: CMC_EE -> ftp 192.168.0.2 6) Enter your FTP server user name and password. Just press <Return> in response to either prompt if there is no user name or password. Username: <your_user_name> Password: <your_password> 7) At the prompt for a remote file, give the pathname to the latest EE22.SYS file on your PC (e.g., c:\EE22.SYS). For the local file use EE22NEW.SYS. Enter “down” at the “dowload or upload” prompt.

EmulationEngine 11a/b/g User's Guide Rev #/Date: 2.0.0 Beta/07.17.03 D-1 APPENDIX D: Error and Status Messages The EmulationEngine may display the following error and status messages in response to incorrect or unexpected user actions or WLAN activity. EmulationEngine or Virtual Station Control Messages Message Description EE Lost SUT (no beacons) The EmulationEngine was joined with the System Under Test but has stopped receiving beacons from it. EE Not joined with System Under Test A requested operation could not be performed because the EmulationEngine is not joined with a System Under Test. Internal system error A 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. Invalid object identifier The vSTA control task received a GET or SET Command message with an invalid Object identifier. Invalid object value The vSTA control task received a SET Command message with an invalid object value. Invalid operation Internal error: the vSTA control task received a Command message with an invalid operation code. Invalid vSTA identifier The vSTA control task received a Command message with an invalid vSTA identifier. Invalid vSTA state for operation A requested operation could not be performed because the specified vSTA is not in the appropriate state. vSTA idle A requested operation could not be performed because the specified vSTA is in the Idle state. vSTA not configured A requested operation could not be performed because the specified vSTA has not been Configured. vSTA not idle A requested operation could not be performed because the specified vSTA is not in the Idle state. vSTA not initialized A requested operation could not be performed because the specified vSTA has not been Initialized. vStaControl() Err writing NOTIFY into UI's queue The vSTA control task cannot post a message because the UI task’s queue is full. This may occur if a web user logs out while the EmulationEngine is running and so may be ignored. 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 the EmulationEngine is running and so may be ignored.
