Layer 2 CRC check Full Performance Test. Perform Layer 2 CRC check test by two groups with different
Media Type such as 100Mbps and 1000Mbps for DUT ports with different maximum speeds.
A. Media Type
 Custom: Clicking this button to pop up a window for scrolling down and selecting the media type
for Port A and B.
 Minimum Waiting Time: DApps-MPT will halt at least for the Minimum Waiting Time you input
here during auto-negotiation process.
 Media Type Waiting Timeout: If the time spent for auto-negotiation exceeds the Media Type
Waiting Timeout you set here, the test will stop and the test result will be fail.
 Link up sequentially: DApps-MPT makes connections to ports sequentially (one-by-one).
Therefore, DUT’s Link LEDs will be ON in a one-by-one manner as well. If any problems happen
during the test, it will be suspended immediately. Users can identify which port is causing the
problem by checking DUT’s port LEDs.
 Link Status Check: DApps-MPT will check all ports in this task are connected properly before test.
 LED Check Setting: If the LED Check Reminder function is enabled, a Checking LED Display
window will pop up when you start the task. This window can remind the user how DUT LEDs’
display should be during the task. You can set the information that will be displayed on Checking
LED Display window here on LED Check Setting field. Also, you can load the image file for DUT
LED as well. If DUT’s LED is not displayed as it should be comparing to the image file displayed on
Checking LED Display window, the user can press the Fail button, or vice versa.
