+Configuration of TRAFFIC dictionary
+-----------------------------------
+
+TRAFFIC dictionary is used for configuration of traffic generator. Default values
+can be found in configuration file ``conf/03_traffic.conf``. These default values
+can be modified by (first option has the highest priorty):
+
+ 1. ``Parameters`` section of testcase defintion
+ 2. command line options specified by ``--test-params`` argument
+ 3. custom configuration file
+
+It is to note, that in case of option 1 and 2, it is possible to specify only
+values, which should be changed. In case of custom configuration file, it is
+required to specify whole ``TRAFFIC`` dictionary with its all values or explicitly
+call and update() method of ``TRAFFIC`` dictionary.
+
+Detailed description of ``TRAFFIC`` dictionary items follows:
+
+.. code-block:: console
+

-- **bidirectional** - specifies if traffic will be uni (False) or bi-directional
- (True); Default: False
-- **iload** - specifies frame rate; Default: 100
-- **multistream** - specifies the number of simulated streams; Default: 0 (i.e.
- multistream feature is disabled)
-- **stream_type** - specifies network layer used for multistream simulation
- the valid values are "L4", "L3" and "L2"; Default: 'L4'
- **conf_file** - sets path to the vswitchperf configuration file, which will be
uploaded to VM; Default: '~/vsperf-yardstick.conf'
- **setup_script** - sets path to the setup script, which will be executed
- **test_params** - specifies a string with a list of vsperf configuration
parameters, which will be passed to the ``--test-params`` CLI argument;

(value ``monitor``).
