Streams - Profile

Total TX Rate indicates the percentage of the total line utilization
which is the sum of all TX rate enabled streams.
Note: The Individual stream can be enabled/disabled even when the test is
started and running. The streams can be enabled one after the other, up to
16, as long as the maximum rate is not reached. For example, if the first
stream is using the full rate available, then no other stream can be enabled.
However, if the first enabled stream uses half rate, then at least another
stream can be enabled using up to half rate. Thus, to enable a second
stream, first set the TX rate value within the non-used rate, then enable it. A
stream cannot be enabled if its MAC address is not valid (it can be either
not resolved or wrongly entered).

Link Capacity indicates the total rate available for traffic generation.
QoS Metrics
Note: QoS Metrics settings apply to all streams.
