CHAPTER 1: Overview
The EmulationEngine is a test and measurement device that
emulates up to 64 wireless stations in an IEEE 802.11 wireless
LAN environment. The EmulationEngine operates in accordance
with the IEEE 802.11a, 802.11b, and 802.11g specifications. 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. The
EmulationEngine software is locked to its specific hardware
platform and feature set through the use of this feature key.
Feature keys can be upgraded at any time to provide access to
additional features.
The objective of the EmulationEngine is to reduce the number of
PC and station NIC cards that are needed to test and stage 802.11
products and wireless LANs in terms of packet performance and
number-of-stations capacity. In addition, it allows a user to fine-
tune system parameters in order to maximize performance during
testing. The primary difference between the EmulationEngine and
other IP Load Generators is:
IP-based Load Generators are per-station devices that do not
reduce the number of PCs and station NIC cards. You can only
configure an IP per station and then send traffic.
The EmulationEngine allows all stations to be emulated on a
single platform and radio chipset thus reducing the cost and
complexity of multiple PCs.
CMC's EmulationEngine creates Virtual Stations (vSTAs) and
generates or passes traffic that will load and stress test a Wireless
LAN and 802.11 products in terms of:
Frame performance
Number-of-stations capacity
Scalability
WLAN optimization
Because a single physical 802.11a/b/g emulator emulates
multiple STAs, it reduces the number of PC and station NIC cards
that are needed to test and stage 802.11 products and wireless
LANs.

information settings that can be defined via 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. The EmulationEngine will load from this file at power-
up/initialization time. It contains basic configuration information.
2) After the EmulationEngine 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.
3) Log files store records of all EmulationEngine activities with a
time stamp indicating when the activity occurred. Logging to the
CLI console, the web-based user interface, or a file can be
enabled/disabled.
4) 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
Communication Machinery Corporation (CMC)
1-4 Rev #/Date: 2.0.0 Beta/07.17.03
section of the web-based user interface can be used to show the
contents of these files.
5) The EE22.SYS file is the EmulationEngine software image file.
6) The keyfile is a reserved file that contains the EmulationEngine
authorization code. It is a hidden file and will only be shown in the
directory list in the CLI’s administrative mode. Do not delete this
file or attempt to access or modify it. It is required by the system.
System Requirements
An A/C power outlet (100~240 V, 50~60 Hz) that will supply
power to the EmulationEngine
A PC with an available serial port or 10/100 Ethernet port that
can be used to send commands to the EmulationEngine
If the web-based user interface is used, the command PC must be
equipped with the following:
; Microsoft Windows 2000/XP
; Microsoft Internet Explorer Version 6.0 or higher
; Recommended Memory: 256 MB
; Recommended Virtual Memory: 300 MB
; Recommended Processor Speed: PIII 700 MHz.
Hardware Characteristics
Ethernet Compatibility: The EmulationEngine can attach
directly to 10BASE-T/100BASE-TX (twisted-pair) Ethernet LAN
Hubs, segments or a PC. All of these must conform to the IEEE
802.3 specification.
Radio Characteristics: The EmulationEngine conforms to the
IEEE 802.11a, 802.11b, and 802.11g specifications. In 802.11a
mode, it operates at the 5GHz Unlicensed National Information
Infrastructure (UNII) band. Data is transmitted over a half-duplex
radio channel operating at up to 54 Megabits per second (Mbps)
using OFDM (Orthogonal Frequency Division Multiplexing). In
802.11b mode, the EmulationEngine operates in the 2.4 GHz
band and sends data at up to 11 Mbps. In 802.11g mode, the
EmulationEngine operates within the 2.4 GHz band using OFDM
at rates up to 54 Mbps.
General Usage Notes
1) The EmulationEngine's default IP address is 192.168.0.50. In
order to establish initial communications between the command
PC and the EmulationEngine using an Ethernet connection, you
must set your PC's IP address and network mask to match this
default address (e.g., IP address: 192.168.0.2, Netmask:
255.255.255.0). After you establish communications using the
EmulationEngine 11a/b/g User's Guide
Rev #/Date: 2.0.0 Beta/07.17.03 1-5
default IP address, you can change the EmulationEngine's and
your command PC's address to match the addressing scheme
used in your network.
2) Depending on your feature key, the EmulationEngine can
operate in 802.11a, 802.11b, or 802.11g wireless mode. The
EmulationEngine's wireless mode affects the devices that you can
select as a System Under Test. For example, an EmulationEngine
that is operating in 802.11a wireless mode will not discover an
802.11b or 802.11g device. Make sure the wireless mode you
select for the EmulationEngine is compatible with the device you
wish to test. See EE->Configure EE in Chapter 5 and “set
wirelessmode” in Chapter 6.
3) The EmulationEngine's 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 programmed in to the
EmulationEngine hardware. The WLAN base MAC address and
mask (ff:ff:ff:ff:00:00) define the range of MAC addresses that can
be assigned to virtual stations. When you specify a starting MAC
address for virtual stations, make sure that address is within the
range defined by the WLAN base MAC address and mask. See
vSTA->New Emulation Group->vSTA and EE->Configure EE in
Chapter 5 and “set eemac” and “set eemask” in Chapter 6.
4) If you use multiple EmulationEngine's at your facility, each
should have a WLAN MAC whose prefix is unique. For example, on
the first EmulationEngine , use WLAN MAC Address:
04:0d:e0:62:23:57 and on the second EmulationEngine, use
WLAN MAC Address: 06:0f:14:62:32:a0.
5) The IP Mask of the EmulationEngine must match the IP subnet
addressing scheme for internal mode testing (it is not used for
external mode). For example, if the EmulationEngine's IP address
is 10.1.40.18 and the System Under Test is 10.1.35.17, then the
subnet mask must be 16 bits or 255.255.0.0 for an internal mode
test.

When an Invalid Data dialog is displayed, click “OK” and reenter a
value that is within the allowable range for the field.
Communication Machinery Corporation (CMC)
5-22 Rev #/Date: 2.0.0 Beta/07.17.03
Using Load Profiles
Load Profiles allow you to control the execution of virtual stations:
Unscheduled or Scheduled. In Unscheduled mode, virtual stations
can be manually controlled. In Scheduled mode, virtual stations
can be run incrementally based on groups (all virtual stations
within the group) or by individual virtual stations.
NOTE: In order to use Scheduled mode, you must disable “Batch
EE Requests” in EmulationEngine configuration (See EE-
>Configure EE). When requests are batched for transmission to
the EmulationEngine, they will not be sent at the scheduled
interval defined by the Load Profile.
Run tests: Select Unscheduled or Scheduled. The default is
Unscheduled. If Scheduled is selected, the Load Profile is in effect
for the scenario. If Unscheduled is selected, the Load Profile is not
in effect.
After: This field defines an initial delay before a run starts:
0...3600 seconds (1 hour). It is the number of seconds after a Run
command has been issued (e.g., the Run button is selected in the
toolbar) that the Load Profile will begin executing.
run: Enter the number of virtual stations to start each time
interval of the load profile. The time interval is specified in the
“every” field.
per: This field defines what scheduling is based on (All vSTA = all
virtual stations, Groups = virtual stations within each group). If
"All vSTA" is selected, the Load Profile will run the next “run”
number of virtual stations at each scheduled iteration. If Group is
selected, the Load Profile will run the next “run” number of virtual
stations from each group at each scheduled iteration. The
scheduled iteration is defined in the “every” field.
every: This field defines the number of seconds between each
repetition of the Load Profile: 1...3600 seconds (1 hour). When this
time expires, the next set of virtual stations (as defined in the run
field) will be executed.

Rev #/Date: 2.0.0 Beta/07.17.03 5-23
Select the Load Profile tab in the Load Profile/Monitors section of
the page to show the Load Profile graph. The Load Profile graph
displays the Load Profile setup: x-Axis = time, y-Axis = Groups or
All vSTA depending on the selection in the per field. The following
illustration shows an example Load Profile setup and graph:
After a delay of five seconds, the user interface will instruct the
EmulationEngine to run four virtual stations. Every five seconds
thereafter, the user interface will instruct the EmulationEngine to
run another four virtual stations until all virtual stations have
been executed. The graph depicts this scheduling scheme.
vSTA Side Bar
In the web-based user interface you can create scenarios that
consist of one or more groups of virtual stations. The group
configuration defines a test sequence that the EmulationEngine
will activate to exercise the System Under Test. Virtual stations
can be configured individually or by group. In internal mode, you
can configure each virtual station and/or group to generate traffic
to the system being tested. You can also configure virtual stations
to operate in external mode where an external load generator will
generate the traffic.

addresses defined by the WLAN Base MAC Address and WLAN
MAC Mask in EmulationEngine configuration (see EE->Configure
EE).
WLAN MAC Mask: The WLAN MAC Mask is a display-only field. It is
defined in EmulationEngine configuration (see EE->Configure EE).
It limits the range of MAC addresses that can be detected on the
wireless LAN and received by the EmulationEngine. 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 the EmulationEngine are:
00:0b:cd:59:00:00 - 00:0b:cd:59:ff:ff. All other MAC addresses will
be filtered out.
Ending MAC Address: Enter the ending MAC address to be used by
virtual stations in this group.

EmulationEngine 11a/b/g User's Guide
Rev #/Date: 2.0.0 Beta/07.17.03 5-27
Traffic 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 the EmulationEngine over 802.3 are mapped
to virtual stations by source IP address and forwarded via 802.11.
Packets coming back via 802.11 are remapped to the originating
MAC address.
Traffic Type: This selection is only applicable if the Traffic Source is
set to Internal. In this release, only ICMP Echo (Ping) is supported.
Target IP Address: Enter the target IP address where ICMP Echo
(Ping) Requests should be sent.

EmulationEngine loses connection to a System Under Test, it
EmulationEngine 11a/b/g User's Guide
Rev #/Date: 2.0.0 Beta/07.17.03 5-31
must be able 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 from the system and received by the
EmulationEngine, this virtual station will attempt to go back to
the state it was in prior to receiving the management frame. If the
virtual station was running a ping test when interrupted, the
virtual station’s ping test will continue. If it was in an associated
state, the virtual station will simply reissue the associate request.
Retries: This field specifies the number of times the
EmulationEngine should issue authentication and association
requests before failing the operation. It can be a value in the range
0...10.
Timeout: This field specifies the timeout value (in milliseconds) for
authentication and association requests. It can be set to a value in

Receive Parameters
EE Polling Interval: This entry defines the interval (in milliseconds)
that the Command PC will poll the EmulationEngine for command
and control messages from the virtual stations. It can be set to a
value in the range: 250...60000 milliseconds (1 minute). If this
time expires without an expected response from the
EmulationEngine, the user interface will display "Busy" next to the
EmulationEngine icon in the toolbar. The "Busy" message
indicates that the EmulationEngine is not responding to the user
interface. Under normal conditions, the "Busy" message may
appear periodically for short periods of time. If the “Busy” message
appears frequently, you may want to increase the value assigned
Communication Machinery Corporation (CMC)
5-40 Rev #/Date: 2.0.0 Beta/07.17.03
to the EE Polling Interval. Also see Chapter 9,
Troubleshooting/EmulationEngine Busy or Not Responding.
Max Messages Per Interval: Specify the maximum number of
messages to be sent in each poll: 1...128.
EE Polling Timeout: This entry defines the time (in milliseconds)
that the Command PC will wait for a response from the
EmulationEngine. It can be set to a value in the range:
500...120000 milliseconds (2 minutes). The recommended value is
two times the EE Polling Interval value. If this time expires without
an expected response from the EmulationEngine, the user
interface will display a dialog indicating that the EmulationEngine
is not responding. When you dismiss the dialog, the status of the
EmulationEngine/System Under Test connection in the toolbar
will display “Offline”. If this dialog and “Offline” status appears
frequently, a larger value should be assigned to the EE Polling
Timeout. Also see Chapter 9, Troubleshooting/EmulationEngine
Busy or Not Responding.
NOTE: Also see the Monitor Update Interval and Monitor Update
Timeout in Monitors->Config Monitors for the interval and update
timeout values that are used by the command PC to collect
statistics values.
Transmit Parameters
Batch EE Requests: This checkbox enables/disables batching of
request messages to be sent to the EmulationEngine. When virtual
stations are running in an iterative fashion or you issue
commands to many virtual stations, this will produce a large
number of requests to the web server on the EmulationEngine.
Request batching will maintain a number of these requests over a
period of time (defined by the Batch Request Interval) and then
issue one large request with all pending instructions.
NOTE: If you are currently running or intend to run a Load Profile,
do not enable Batch EE Requests.
Batch Request Interval: If "Batch EE Requests" is checked/enabled,
specify the interval at which the web-based user interface will

EmulationEngine 11a/b/g User's Guide
Rev #/Date: 2.0.0 Beta/07.17.03 5-41
If you change the IP Address or IP Netmask, a reboot of the
EmulationEngine is required for these changes to take effect.
EE Id: This field is set by the system and cannot be changed.
EE Address: This field shows the EmulationEngine's current IP
address.
IP Address: Enter the EmulationEngine's new IP address. Use a dot
IP address (e.g., 192.168.0.50).
IP Netmask: Enter the EmulationEngine's network mask. The
network mask of the EmulationEngine must match the IP subnet
addressing scheme for internal mode testing (it is not used for
external mode). For example, if the EmulationEngine'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.
Communication Machinery Corporation (CMC)
5-42 Rev #/Date: 2.0.0 Beta/07.17.03
NOTE: If you change the IP Address of the EmulationEngine and
reboot, the web client does not automatically change its
EmulationEngine IP address. You will need to do it manually. If
you forget, you will need to restart the web browser after the
EmulationEngine has rebooted. However, you can also double-
click on the engine address in the toolbar->status bar to display a
dialog that will let you change the address without restarting.
WLAN MAC Base Address: 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 programmed in
to the EmulationEngine hardware. The address can be changed to
any non-broadcast or non-multicast valid MAC address. If you use
multiple EmulationEngine's at your facility, each should have a
WLAN MAC whose prefix is unique. For example, on the first
EmulationEngine , use WLAN MAC Address: 04:0d:e0:62:23:57
and on the second EmulationEngine, use WLAN MAC
Address: 06:0f:14:62:32:a0.
WLAN MAC Mask: This address is used in conjunction with the
WLAN Base MAC Address for configuration of virtual stations. If
for example, 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 WLAN and received by the EmulationEngine are:
00:0b:cd:59:00:00 - 00:0b:cd:59:ff:ff. All other MAC addresses will
be filtered out. The mask limits the range of MAC addresses that
are assigned to virtual stations. The mask that is specified here
will be displayed in the WLAN MAC Mask field when the vSTA tab
is selected in the New Emulation Group dialog (See vSTA->New
Group->vSTA).
Wireless Mode: Select a wireless mode (11a, 11b, or 11g) from the
list box. The items that are available in this list box will be
different depending on the feature set that you ordered from CMC.
The wireless mode also affects the types of devices the

A monitor is one or more user-selected statistics counters that the
web-based user interface will collect from the EmulationEngine
and display in the user-selected format (i.e., line graph, bar graph
or table). All data collected can be exported. Monitors are based on
Linegraphs, Bargraphs and Tables. You can use these to monitor
the summary statistics of the EmulationEngine or a summary
“Master vSTA” that shows virtual station statistics across all
virtual stations.
NOTES:
1) Each scenario can include up to four different monitors.
2) Monitor values are stored in memory on the command PC. If
you run one or more monitors for an extended period of time,
available memory may become depleted and this can affect the
performance of the command PC.

The New Monitor dialog is a tabbed dialog that can be used to
define predefined, summary, and summary virtual station
counters to be maintained during the execution of a test.
Monitors->New Monitor->Predefined

Summary statistics provide a summary report taken over a set of
virtual stations. The virtual station set can be a defined group or
all virtual stations currently in the system. In contrast, the
individual virtual station statistics report provides a list of
statistics and counters for all virtual stations. The summary
report provides a summary of the statistics and counters taken
over the indicated set of virtual stations. The summary gives, for
each counter, the minimum and maximum values for that counter
found in the set of virtual stations examined, the average value,
and where applicable the total (sum) over the set of virtual
stations. The Avg fields (i.e., Receive Rate Avg, Transmit Rate
(Short Frame) Avg, and Transmit Rate (Long Frame) Avg) in the
Data Rate section of the summary statistics display is the average
rate for the master vSTA since the time the EmulationEngine
joined to a System Under Test. See "Chapter 8, Statistics
Counters" for a description of statistics counters that may be
displayed in this report.
