Test Procedure

Follow these steps to test the design examples in hardware:

  1. Run the following command in the system console to start the test.

    TEST_EXT_LB <channel> <speed> <burst_size>

    Example: TEST_EXT_LB 0 2.5G 1000000000

    Table 3.  Command Parameters
    Parameter Valid Values Description
    channel 0, 1 The channel number to test.
    speed 1G, 2.5G The PHY speed.
    burst_size An integer value The number of packets to generate for the test.
  2. When the test is completed, observe the output displayed. The following diagrams show excerpts of the output, which shows that the Ethernet packet monitor block receives the same number of packets generated without error, and the TX and RX statistics counters.
