This testvar must be explicitly defined in the configuration file
This parameter specifies the MAC address CDRouter will use for the primary LAN client on this LAN test interface. This value must be unique and cannot be set to the MAC address of the underlying physical interface specified by the testvar lanInterface. If not specified, a random MAC address will be generated using the OUI specified by the cdrouterOui testvar.
Any additional LAN hosts that are created during test cases will also automatically generate a MAC address using the cdrouterOui value.
