+T-Rex can perform a verification run for a longer duration once the binary search of the
+RFC2544 trials have completed. This duration should be at least 60 seconds. This is similar
+to other traffic generator functionality where a more sustained time can be attempted to
+verify longer runs from the result of the search. This can be configured with the following
+params
+
+.. code-block:: console
+
+    TRAFFICGEN_TREX_VERIFICATION_MODE = False

+The duration and maximum number of attempted verification trials can be set to change the
+behavior of this step. If the verification step fails, it will resume the binary search
+with new values where the maximum output will be the last attempted frame rate minus the
+current set thresh hold.
