+Referencing parameter values
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+It is possible to use a special macro ``#PARAM()`` to refer to the value of
+another configuration parameter. This reference is evaluated during
+access of the parameter value (by ``settings.getValue()`` call), so it
+can refer to parameters created during VSPERF runtime, e.g. NICS dictionary.
+It can be used to reflect DUT HW details in the testcase definition.
+
+Example:
+
+.. code:: python
+
+ {
+ ...
+ "Name": "testcase",
+ "Parameters" : {
+ "TRAFFIC" : {
+ 'l2': {
+ # set destination MAC to the MAC of the first
+ # interface from WHITELIST_NICS list
+ 'dstmac' : '#PARAM(NICS[0]["mac"])',
+ },
+ },
+ ...
+
