Fig. 21 Address Caching Capacity Test Options

Common Options

  • Iterations

    The number of times to repeat each test trial with the same set of test parameters.

MAC Address Settings

  • Test Port Address Mode

    Defines how to generate the test port MAC address.

  • Learn Port DMAC Mode

    Defines how to generate DMAC address in frames from the learning port.

  • Learning Sequence

    Select how the MAC address learning sequence is scheduled.

  • Learning Base Address

    The first 3 bytes of the MAC addresses used for the learning test. It is necessary to use a different base address than the default Xena base address (04.F4.BC) when running a test using multiple addresses to avoid conflicts with other unused ports on the Xena tester.

  • Initial Count

    The starting address count to use.

  • Maximum Count

    The maximum address count to use.

  • Minimum Count

    The minimum address count to use. If the trial reaches this value the test is stopped and the result will be FAILed.

  • Resolution Count

    The trial stops when the difference between the current and the last successful trial is less than the Resolution.

Learning Rate Settings

  • Learning Rate

    The learning rate in frames/second to use.

DUT Address Learning Reset

  • Toggle Sync States

    If checked the sync state of the test ports will be toggled off and on between test trials. Enabling this may help clearing the MAC learning tables in the DUT and speed up the test.

  • Sync State Off Period

    The amount of seconds the port sync states will be off.

  • Delay After Sync On

    Defines how long time Xena2889 will wait after the reset before it continues with the test.

  • Switch Test Port Roles

    If checked the port with the Test and Learning roles will be swapped between test trials. Enabling this may help clearing the MAC learning tables in the DUT and speed up the test.

  • DUT Aging Time

    If none of the two options above are checked the test will wait for the specified seconds between trials to ensure that the MAC table in the DUT has been cleared.

Misc. Options

  • Fast Run Resolution

    Enable this option to perform fast resolution of a test run based on polled data.

Port Role Configuration

  • Used?

    If checked the port will be used in this test.

  • Port Role

    Used to place the port in Test Port, Learning Port, or Monitoring Port.

Note

Only one test port, one learning port and one monitoring port are allowed in this test.
