Select “No” to delete the virtual station definitions in the EmulationEngine and create a new empty scenario. !" Select “Cancel” to retain the virtual stations in the EmulationEngine but do not create a new empty scenario.
EmulationEngine 11a/b/g User's Guide !" Uncheck the “Show On Startup” checkbox if you do not want to show this screen each time you access the EmulationEngine web server. You can restore this screen on start-up in the UI Configuration dialog (See Configuration->Preferences).
Communication Machinery Corporation (CMC) Open Existing Scenario If you selected “Open Existing Scenario” in the welcome screen and have not joined with a target system, the Select System Under Test dialog is displayed as described above. After you have joined with a target system, the Open Scenario dialog will be displayed: The list box shows a list of scenario files on the EmulationEngine. Select “Browse” to select from scenario files stored on the command PC.
EmulationEngine 11a/b/g User's Guide The content of this page will be different depending on whether you created a new scenario, opened an existing scenario, or cancelled/closed any of the start-up dialogs. This example page shows an existing scenario where one group is defined. This section of the page will be blank (No Scenario Defined) if a scenario has not been created.
Communication Machinery Corporation (CMC) Wireless Mode: This field shows the EmulationEngine’s current wireless mode (11a, 11b, or 11g). You can select a different wireless mode from the list box. The web-based user interface will issue a command to the EmulationEngine to change its wireless mode and scan for compatible systems. The results of the new scan will be reflected in the BSSIDs in the list box. Click on a BSSID in the list box and click “Join” to continue.
EmulationEngine 11a/b/g User's Guide Step 3) If you want the EmulationEngine to dynamically assign IP addresses, select DHCP from the Address Generation drop-down list box. Otherwise, enter an IP address in the Starting IP Address field to define the starting IP address to be used by virtual stations that are created in this scenario. Virtual stations will be created with unique IP addresses, sequentially or randomly, based on this starting IP address. Step 4) Select the Traffic tab.
Communication Machinery Corporation (CMC) Step 5) Make sure the Target IP Address field is set to the address of a target server to be pinged. The default IP address (0.0.0.0) shown in this example screen must be replaced by a valid IP address (e.g., 10.10.10.19). Click “Create” to create a group with five virtual stations. See "vSTA->New Group" for more information about defining and editing groups and virtual stations in a scenario.

EmulationEngine 11a/b/g User's Guide About/Using the Main Page The following illustration shows the general format of the main page where a scenario with one group of virtual stations has been defined and the group tab (Grp_1) is selected: When the “Group Control” tab is selected, the main page will show the Load Profile and a list of devices that have been discovered (if any) in a scan: 080104 5-11
Communication Machinery Corporation (CMC) !" Menu Toolbar: The top-left toolbar at the top of the page is a drop-down menu bar of all EmulationEngine functions. !" Status Toolbar: The top-right toolbar shows the status of the EmulationEngine, the System Under Test and the current time on the command PC. The status (e.g., Online) next to the EmulationEngine IP Address Address indicates the current status of the EmulationEngine with the web-based user interface.
EmulationEngine 11a/b/g User's Guide 080104 !" Scenario Toolbar: The buttons in this section of the toolbar can be used to run, pause, stop, restart, or refresh the entire scenario of all virtual stations. !" vSTA Toolbar: The buttons in this toolbar are used to initialize, authenticate, associate, run, pause, stop, disassociate, de-authenticate, restart, or refresh selected virtual stations or groups of virtual stations.
Communication Machinery Corporation (CMC) Group Control Grid When the Group Control tab is selected, the table shows the status of each group and its associated virtual stations: Group: This field displays the name of each group. The name is assigned in the New Emulation Group dialog (See vSTA->New Group). The remaining fields in the group line are counters that show the state of each group’s virtual stations during a test.
EmulationEngine 11a/b/g User's Guide Total: This field shows the total number of virtual stations in each group. Down: This field shows the total number of virtual stations in a group that have not been configured in the EmulationEngine and are in a “down” state. Configured: This field shows the total number of virtual stations in each group that have been configured in the EmulationEngine.
Communication Machinery Corporation (CMC) Status Messages: This column shows status and/or error messages returned by the EmulationEngine for each virtual station in the scenario group. See Appendix D for a list of messages that may be displayed in this column. Pkts Rcvd: This column shows the total number of packets received by each virtual station in this group. Pkts Xmtd: This column shows the total number of packets transmitted by each virtual station in this group.
EmulationEngine 11a/b/g User's Guide See vSTA->Add New vSTA to Group for information about the fields in this dialog. You can right click on selected virtual stations to display the vSTA menu. Any menu option will affect the selected virtual station(s).
Communication Machinery Corporation (CMC) Group Tab Columns: Within a group, you can double click on the table heading to configure the columns that are displayed. Select one or more items in the All Columns list box and click the [>>] button to move them to the Selected Columns list box. Click “Modify” to add the columns to the group table. Select “Reset” to return the columns to their default setting.
EmulationEngine 11a/b/g User's Guide systems with a higher signal strength value have a better/higher transmission rate to the EmulationEngine. You can select “Rescan” to instruct the EmulationEngine to rescan for all systems. The devices shown in this list box will be displayed in the Select System Under Test dialog where you can choose a system to test. Load Profile/Monitor Graphs The bottom half of the web page is reserved for charts that graphically illustrate a load profile and monitor test results.
Communication Machinery Corporation (CMC) Range Checking/Error Messages In the dialogs described later in this chapter, the user interface will verify all entries that require values within a specified range. If a field can contain a very large number, do not enter commas (,) for values larger than 999 (e.g., use 1000 rather than 1,000). If you use an invalid character in a field or specify a value that is not within range, a dialog will tell you the allowable range.
EmulationEngine 11a/b/g User's Guide 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.
Communication Machinery Corporation (CMC) 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.
EmulationEngine 11a/b/g User's Guide Group Name: Use a group name that helps you identify the devices that will be tested (e.g., Warehouse, Stock_Room, Control_Tour, Shop_Floor, etc.). It can be up to 12 characters (a...z, 0..9, and underscore (_)). EE Address: This field shows the IP address of the EmulationEngine that will run this scenario/test. Number of Virtual Stations: Enter the number of virtual stations (0...64) to be created in this scenario group. The default value is 5.
Communication Machinery Corporation (CMC) Netmask: This field shows the network mask to be used by virtual stations in this group. It is not settable here. It is global for all virtual stations and is an EmulationEngine configuration parameter. Ending IP Address: If Random is selected in the Address Generation field, enter the ending IP address to be used by virtual stations in this group when generating random addresses within a range.
