+Card Bandwidth Options
+~~~~~~~~~~~~~~~~~~~~~~
+
+T-Rex API will attempt to retrieve the highest possible speed from the card using internal
+calls to port information. If you are using two separate cards then it will take the lowest
+of the two cards as the max speed. If necessary you can try to force the API to use a
+specific maximum speed per port. The below configurations can be adjusted to enable this.

+.. code-block:: console
+
+ TRAFFICGEN_TREX_FORCE_PORT_SPEED = True
+ TRAFFICGEN_TREX_PORT_SPEED = 40000 # 40 gig
+
+**Note::** Setting higher than possible speeds will result in unpredictable behavior when running
+tests such as duration inaccuracy and/or complete test failure.
