EmulationEngine 11a/b/g User's Guide
CHAPTER 6:
The Command Line Interface (CLI)
The CLI can be used to display and modify the configuration of the
EmulationEngine from a PC that is connected via Telnet or the serial port.
The CLI also includes commands to configure and run virtual stations,
display statistics, and to access the System Under Test. The
EmulationEngine maintains statistics and event log files that you can
configure and display using CLI commands.
CLI Usage Notes
1) CLI commands are not case sensitive (e.g., "set Date" is the same as
"set date").
2) You do not need to enter the entire command string to execute a
command. Only the number of unique characters required to identify the
command are needed (e.g., "se da" will execute 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 range:
0...2,147,483,647. Do not enter commas (,) for values larger than 999
(e.g., use 1000 rather than 1,000).
4) It is very important to keep a printed record of configuration
parameters. See "Configuration Records" in Chapter 9.
User Log-In
The EE login prompt is displayed after you successfully establish a
connection to the EmulationEngine. See “Initial Setup” in Chapter 4. When
you have successfully established this connection, the CLI prompts you to
enter a log in name and password.
EE login: Admin
Password: **
The default log in user name is "Admin". The default password is "EE".
Both entries are case sensitive (i.e., the default user name is "Admin", not
"admin"). After you enter a valid user name and password, the CLI
displays a version banner, the current system time and status, and a CLI
prompt.

scan
This command scans for Basic Service Set IDs and, optionally, joins with
the System Under Test. The EmulationEngine’s wireless mode affects the
type of devices that can be discovered in a scan. See “set wirelessmode”
to change the EmulationEngine’s wireless mode.
NOTE: If a test is in process (see the run command), a scan operation will
be disruptive to the normal testing operations of the EmulationEngine.

following message:
**You must do a "join" or a "scan" with the join option first.
Use the System Under Test commands described above to join with a
System Under Test before using the commands in this group.
The following diagram illustrates the life cycle of a virtual station from its
null (un-configured) state to its running state in the active execution of a
test. This illustration will help you determine the sequence of commands
to use to achieve the desired results with virtual station setup and control
commands.

autoconf
This command can be used to configure, initialize, authenticate and
associate a number of virtual stations using a single command. It can be
issued multiple times. The first time the command is issued the base MAC
and IP virtual station addresses must be specified. For subsequent
commands, the IP and MAC address parameters are not required. The
specified number of virtual stations will be configured using either default
values or the values specified in the command line. 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.

Communication Machinery Corporation (CMC)
[group ]: Optional group ID number (1...64).
[csmode persistent|non-persistent]: Connection mode (persistent or nonpersistent).
[retry ]: If csmode is presistent, this parameter specifies the
Authentication/Association retry limit (1...2,147,483,647 or zero (=no
retries)).
[timeout ]: If csmode is presistent, this parameter specifies the
Authentication/Association timeout in milliseconds (1...2,147,483,647 or
zero (=immediate timeout)).
[authentication open-system|shared-key]: Authentication mode (opensystem or shared-key).
[encryption on|off]: Encryption mode (on or off).
[keyindex ]: If encryption is on, a shared key index number
(1...4).
[cipher wep]: Enables WEP cipher mode.
[mode internal|external]: If mode is internal, virtual station(s) will
generate data using Ping (ICMP Echo Request) packets. Each virtual
station will run a ping transmitter process. The packets will 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) will be generated by an external host connected to the same
LAN as the EmulationEngine. For vSTAs configured at layer 3, IP and ARP
packets generated from this host that contain the virtual station's IP
address as a source will be translated at the MAC layer to appear as if
sourced from the virtual station's MAC address. Default: Internal.
[target ]: Target host's IP address. If mode is Internal this
parameter is required. Default: None.
[count ]: Number of ping packets to send: 0...2,147,483,647.
Default: 1000.
[size ]: Size of ping data buffer (64...1024). Default: 1024.
[dhcpmode ]: The DHCP mode allows virtual stations to
have IP addresses dynamically assigned 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, the EmulationEngine will
automatically initiate lease negotiation if association succeeds. The default
value is off.
[layer <2|3>]: If mode is external, this parameter specifies how the
external data stream is captured. If layer is 2, frames will be captured
based on the source 802.3 MAC address. If layer is 3, frames will be
captured based on the source IP address. The default value is 3.
[fragmentthreshold ]:  can be a value in the range
256...2346 and defines the fragmentation threshold for the virtual
station(s) configured by this command. The fragmentation threshold will
limit the number of bytes in any 802.11 frame transmitted by the vSTA. If
 is set to 2346 (i.e., the maximum 802.11 frame size),
fragmentation is effectively disabled. The default value is 2346.

[rtsthreshold ]:  can be a value in the range
1...2346 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 will require a successful RTS/CTS frame
exchange before the frame is transmitted. The minimum value (1)
effectively requires RTS/CTS for all transmit frames. The maximum value
(2346) is the maximum 802.11 frame size and effectively disables RTS.
The default value is 2346.

authentication: This attribute sets the authentication mode (opensystem or shared-key) for all virtual stations in the specified group.
cipher: This attribute sets the cipher mode (wep) for all virtual stations in
the specified group.
count: If mode is “internal”, this attribute sets the ping count
(0...2,147,483,647)
csmode: When csmode is enabled (persistent), virtual stations in this
group will remain persistent (connected) if the System Under Test deauthenticates or disassociates. If the EmulationEngine loses connection to
a System Under Test, persistence will allow 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 the
EmulationEngine, the virtual station will attempt 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 will continue. If it was in an
associated state, the virtual station will reissue the associate request.
dhcpmode: The DHCP mode allows virtual stations to have IP addresses
dynamically assigned 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, the EmulationEngine will automatically initiate lease
negotiation if association succeeds. The default value is off.
encryption: This attribute sets the encryption mode (on or off) for all
virtual stations in the specified group.
fragmentthreshold: This attribute defines the fragmentation threshold
for the virtual station(s) configured by this command. The fragmentation
threshold will limit the number of bytes in any 802.11 frame transmitted
by the vSTA. If  is set to 2346 (i.e., the maximum 802.11 frame
size), fragmentation is effectively disabled. The default value is 2346.
keyindex: If encryption is “on”, this attribute assigns a shared key index
number to all virtual stations in the specified group.

EmulationEngine 11a/b/g User's Guide
layer: If mode is external, this parameter specifies how the external data
stream is captured. If layer is 2, frames will be captured based on the
source 802.3 MAC address. If layer is 3, frames will be captured based on
the source IP address. The default value is 3.
lp: If mode is “internal”, this attribute defines the Load Protocol (ping).
mode: This attribute defines the test mode (internal or external) for all
virtual stations in the specified group.
retry: If csmode is “persistent”, this attribute defines the group’s
Authentication/Association retry limit (zero = no retries).
rtsthreshold: This attribute 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 will require a successful
RTS/CTS frame exchange before the frame is transmitted. The minimum
value (1) effectively requires RTS/CTS for all transmit frames. The
maximum value (2346) is the maximum 802.11 frame size and effectively
disables RTS. The default value is 2346.
size: If mode is “internal”, this attribute defines the Ping Packet Size
(64...1024).
target: If mode is “internal”, this attribute defines the target IP address.
timeout: If csmode is “persistent”, this attribute defines the
Authentication/Association timeout in milliseconds (zero = immediate
timeout)

halt
This command initiates an immediate halt of the load application currently
being run by one or more virtual stations. The virtual station(s) must be
configured, initialized, authenticated, associated and running a load
application. As long as the specified virtual station remains in the
associated state, the load application may be re-started by issuing a run
command. The following command will execute the halt for one or all
virtual stations.

Example:
CMC_EE -> reset vsta 1
CMC_EE ->
save vsta stats
This command writes all statistics for virtual stations to a file in the flash
file system. The file will be stored in the /Statistics subdirectory and
named "Vsta#Stats.dat" (where "#" is the virtual station ID).
save vsta  stats
: Virtual Station ID (1...64), "all", or "master". If  is
set to all (i.e., save vsta all stats), statistics for all virtual stations are
written to individual files. If  is set to "master" (i.e., save vsta
master stats), EmulationEngine statistics information are written in the file
/Statistics/VstaMasterStats.dat.
Example:
CMC_EE -> save vsta 1 stats
Wrote vSTA 1 statistics to file
CMC_EE ->
save vsta all summary
This command saves cumulative summary statistics for all virtual stations
to the file /Statistics/VstaAllSumm.dat.

Example:
CMC_EE -> save vsta all summary
Wrote vSTA all summary to file
CMC_EE ->

authentication: This attribute sets the authentication mode (opensystem or shared-key) for virtual station(s) configured by this command.
cipher: This attribute sets the cipher mode (wep) for virtual station(s)
configured by this command.
count: If mode is “internal”, this attribute sets the ping count
(0...2,147,483,647)
csmode: When csmode is enabled (persistent), virtual stations will
remain persistent (connected) if the System Under Test de-authenticates
or disassociates. If the EmulationEngine loses connection to a System
Under Test, persistence will allow 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 the
EmulationEngine, the virtual station will attempt 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 will continue. If it was in an
associated state, the virtual station will reissue the associate request.
dhcpmode: The DHCP mode allows virtual stations to have IP addresses
dynamically assigned 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, the EmulationEngine will automatically initiate lease
negotiation if association succeeds. The default value is off.

encryption: This attribute sets the encryption mode (on or off) for
virtual station(s) configured by this command.
fragmentthreshold: This attribute defines the fragmentation threshold
for the virtual station(s) configured by this command. The fragmentation
threshold will limit the number of bytes in any 802.11 frame transmitted
by the vSTA. If  is set to 2346 (i.e., the maximum 802.11 frame
size), fragmentation is effectively disabled. The default value is 2346.
group: The value of this attribute assigns one or more virtual stations to
a group (1...64).
ip: This attribute assigns an IP address to an individual virtual station.
keyindex: If encryption is “on”, this attribute assigns a shared key index
number to virtual station(s) configured by this command.
layer: If mode is external, this parameter specifies how the external data
stream is captured. If layer is 2, frames will be captured based on the
source 802.3 MAC address. If layer is 3, frames will be captured based on
the source IP address. The default value is 3.
lp: If mode is “internal”, this attribute defines the Load Protocol (ping).
mac: This attribute assigns an MAC address to an individual virtual
station.
mode: This attribute defines the test mode (internal or external) for
virtual station(s) configured by this command.
retry: If csmode is “persistent”, this attribute defines the
Authentication/Association retry limit (zero = no retries).
rtsthreshold: This attribute 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 will require a successful
RTS/CTS frame exchange before the frame is transmitted. The minimum
value (1) effectively requires RTS/CTS for all transmit frames. The
maximum value (2346) is the maximum 802.11 frame size and effectively
disables RTS. The default value is 2346.
size: If mode is “internal”, this attribute defines the Ping Packet Size
(64...1024).
target: If mode is “internal”, this attribute defines the target IP address.
timeout: If csmode is “persistent”, this attribute defines the
Authentication/Association timeout in milliseconds (zero = immediate
timeout).
