Getting interface statistics with ethtool
=========================================

.. toctree::
	:hidden:

Check that ethtool shows interface statistics.

Scenarios: X3-ET003.



#. Run ' **ethtool** -S **iut_if'** on IUT. Check that it terminated with zero exit code and did not print anything to **stderr**.

#. Save current values of Tx and Rx bytes counters from **ethtool** output.

#. Create a pair of connected sockets of type **sock_type** on IUT and Tester, send some data in both directions between them, receive and check it.

#. Wait for a while to let statistics counters update.

#. Again run ' **ethtool** -S **iut_if'** on IUT. Check that it terminated with zero exit code and did not print anything to **stderr**.

#. Obtain new values of Tx and Rx bytes counters from **ethtool** output, check that they increased.
