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 )
3) module enable (controlled by set evlog module 
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
Rev #/Date: 2.0.0 Beta/07.17.03
7-1
Communication Machinery Corporation (CMC)
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 : 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  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.
7-2
Rev #/Date: 2.0.0 Beta/07.17.03
EmulationEngine 11a/b/g User's Guide
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  : This command prints
event records in log file A or B. If no starting record number
 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.

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

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 webbased 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.

Rev #/Date: 2.0.0 Beta/07.17.03
EmulationEngine 11a/b/g User's Guide
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:

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.

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 
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
 in response to either prompt if there is no user name or
password.
Username: 
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.
Remote File: c:\EE22.SYS
Local File: EE22NEW.SYS
download or upload: down
Getting @192.168.0.2:c:\EE22.SYS -> EE22NEW.SYS

1007441 bytes
CMC_EE ->
8) When the transfer is complete, use the "ls" command to verify
that the size of the file in Flash is the same number of bytes as the
file on the FTP server/command PC.
CMC_EE -> ls
9) At the CMC_EE-> prompt, type the following command to move
the file and use the correct boot name.
CMC_EE -> mv EE22NEW.SYS EE22.SYS
10) When the move is complete, use the "ls" command to verify the
file has been moved with the correct name.
CMC_EE -> ls
11) Use the "reboot" command to reboot the EmulationEngine and
to activate the new software.
CMC_EE -> reboot
After reboot, you must reestablish the telnet session in order to log
back in to the CLI. If the CLI displays the message “This
EmulationEngine has not been Node Locked” after you enter the
EE login name and password, see “Missing Key File” in Chapter 9.
