Performing an internal loopback test

During an internal loopback test, packets are looped back at the PHY device. No connector is needed, as in the external loopback test, and you can run the test with or without another device attached to the test port.

To perform an internal loopback test on a port:

  1. From the Device Manager menu bar, choose Edit > Port.
    2. The Port dialog box opens with the Interface tab displayed.
  2. Set AdminStatus to testing.
  3. Click the Test tab.
    4. The Test tab opens.
  4. Click Int. Loopback.
    5. Let the test run for several seconds.
  5. Click Stop to stop the test.
    6. The result, Fail or Success, is shown along with packet counts.
