Back-to-back Test Settings
The objective of this test is to find the maximum number of frames at
maximum rate that can be sent without frame loss. A number of frames are
sent with minimum inter-frame gaps to the unit under test and the number
of forwarded frames are counted. If the count of transmitted frames is
equal to the number of forwarded frames, the length of the time is
increased and the test is rerun. If the number of forwarded frames is less
than the number of transmitted frames, the duration is reduced and the
test is rerun. The back-to-back value is the number of frames in the longest
time that the device under test (DUT) can handle without any frames loss.
The test performs the number of defined trials.
The back-to-back test is performed for each defined frame size.


Trial qty: indicates the number of test trials performed for each
specified frame size.

