11. Scripted Armageddon Test

Goal: Use RFC-2544 as a guide to create an Armageddon connection that can run automatically through various payload sizes and rates for a specified duration.

Return to LANforge-FIRE Cookbook

In this example, LANforge is used to setup a scripted connection that will iterate through a user-defined list of payload sizes and transmission rates. Each iteration will run for a user-defined duration with a user-defined pause between iterations. A summary text report is generated at the conclusion of all iterations.

1. Create an Armageddon connection. For details refer to: Armageddon Testing (Accelerated UDP)
2. Modify the Armageddon connection to add the script.

   A: Highlight the Armageddon connection and select Modify.
   B: Select the Script button on Endpoint A.
   C: Select the Script Type, RFC-2544. Note: A default set of payload sizes are setup based on RFC-2544 but, can be changed by typing over the default values. Note: For Armageddon UDP connections, 'payload size' refers to size of the ethernet frame size.

3. Setup script options. For details refer to: LANforge User's Guide: Scripted Armageddon Cross Connect

   A: Select Symmetric for the script to run both endpoints for a bi-directional traffic test.
   B: Set the Run and Pause Duration, modify Rates and Payload Sizes as needed.
   C: Note the total number of Script Iterations and Estimated Total Duration to help determine how long it will take to run this script.
   D: Select OK to close the Add/Modify Script window.
   E: The Script Type for Endpoint B is set to NONE because Endpoint A is controlling both ends of the connection in this symmetric script example.
   F: Select OK to close the Create/Modify Cross Connect window.

4. Start the Scripted Armageddon Cross Connect.

   A: Highlight the Armageddon connection and select Start.
   B: A script report window will pop up and show the details of each iteration of the scripted connection as it is run.
   C: At the conclusion of the script, the report window will display a summary of the entire scripted connection results. Full Script Report for this example. - per iteration details - raw CSV data for all iterations - spreadsheet matrices for creating your own 3D graphs - system information
