Changing MAC address and receiving
==================================

.. toctree::
	:hidden:

Check that MAC address can be changed and after that packets sent to the new address can be received.



#. Enable or disable promiscuous mode on the IUT interface according to **promisc** parameter.

#. Create UDP socket on IUT, bind it to **iut_addr**.

#. Create a CSAP on IUT to capture UDP packets sent to **iut_addr**.

#. Create a CSAP on Tester to send packets to **iut_addr**.

#. Send a packet to **iut_lladdr** MAC address (currently set on the IUT interface) from the Tester CSAP. Check that IUT socket receives data and IUT CSAP captures the packet.

#. Send a packet to **iut_alien_mac** MAC address from the Tester CSAP. Check that IUT socket does not receive data. Check that IUT CSAP captures the packet only when **promisc** is ``TRUE``.

#. Change MAC address to **iut_alien_mac** on the IUT interface. Check that the new address is reported for the interface after that.

#. Send a packet to **iut_lladdr** MAC address from the Tester CSAP. Check that IUT socket does not receive data. Check that IUT CSAP captures the packet only when **promisc** is ``TRUE``.

#. Send a packet to **iut_alien_mac** MAC address (currently set on the IUT interface) from the Tester CSAP. Check that IUT socket receives data and IUT CSAP captures the packet.
