This is a feature that could allow customer assign Vantage to detect the port status before the traffic start.
Vantage would detect the port status, for example:
Customer select port 0 and port 1 into the list, Vantage would check port 0 and port 1 status.
If those two ports are link up, the test would start. If not test would wait until that two port are up.

3. Enable the feature "Wait for tester to input DUT serial number before test star"
4. Select the ports which you want.
