Testing AP Band Steering with the AP-Auto Automated Test Suite

Goal: Run an AP-Auto test for an AP using the LANforge CT523c or similar system in order to test how successfully an AP conducts band steering. The AP-Auto test is similar to the TR-398 test, but is designed to be functional with a minimum amount of test equipment. A 2-radio LANforge system and DUT is all that is required to run these tests.

In this test scenario, the LANforge CT523 is used to create stations and run the Band Steering test. This example assumes you have some experience with Chamber View, and that you have a LANforge system and a DUT AP. The AP and LANforge may be in chambers, but that is not required. This feature requires LANforge version 5.4.2 or higher.

  1. If you haven't setup or performed AP-Auto tests on your LANforge system, please refer to the AP-Auto Test Suite Setup guide for quick setup.
  2. Running the AP-Auto Band Steering Test:
    1. Open the AP-Auto Test window. screenshot
    2. In the AP-Auto Settings Tab:

      1. Select the DUT 2G and DUT 5G SSIDs. This test requires that each DUT use one shared SSID across all bands. Most DUTs will default to this behavior once they have been configured for band steering.
      2. Select the LANforge radios to be used in this test. You need at least one 2.4Ghz radio, one 5Ghz radio, and one Dual-Band radio for full functionality.
      3. At the bottom, select the Band-Steering test checkbox.
    3. Your Advanced Configuration tab should look similar to the following: screenshot
    4. Modifying the band station count fields will have the most direct effect on the 'PASS/FAIL' results of this test (E.g. increasing station count on the loaded band might increase likelihood of DUT steering new clients to the less crowded band).
    5. When the configuration is complete, click the Start button (which will change to Stop once start is clicked) to start the test. An interactive report tab will be created and will be updated as the test runs. screenshot
    6. You can change the test result verbosity level by adjusting the Verbosity slider. Maximizing it will show all generated figures and data. The verbosity also affects the length of the saved report.
    7. At the end of the test, click the Save HTML button to save an HTML report and generate the PDF. The PDF file will be linked from the HTML page. You can also click Save PDF and the browser will be directed to open the pdf file directly. Please see this example AP-Auto Band-Steering Report.
