****************
Test NTP Service
****************

Description
===========

DUT0 is configured to obtain time information
from a static configured NTP server

Scenario
========

.. include:: ntpclient/testntpservice

.. raw:: html

  <hr>

*****************************
Test NTP Service Specific VRF
*****************************

Description
===========

DUT0 is configured to obtain time information
from an NTP server via VRF (Virtual Routing and
Forwarding).

Scenario
========

.. include:: ntpclient/testntpservicespecificvrf

.. raw:: html

  <hr>

*************************************
Test NTP Service Specific VRF and PBR
*************************************

Description
===========

Simple scenario to check NTP service using a
specific VRF and PBR (Policy Based Routing).

Scenario
========

.. include:: ntpclient/testntpservicespecificvrfandpbr

.. raw:: html

  <hr>

************************
Test RTC Synchronization
************************

Description
===========

Checks that RTC is working properly on machines
that have an RTC device.

Scenario
========

.. include:: ntpclient/testrtcsynchronization

.. raw:: html

  <hr>

***********************************
Test RTC Synchronization With Drift
***********************************

Description
===========

Tests that RTC is working properly on machines
that have an RTC device (while adjusting the
drift too).

Scenario
========

.. include:: ntpclient/testrtcsynchronizationwithdrift

.. raw:: html

  <hr>

************************************************
Test NTP Service With Client Authentication Only
************************************************

Description
===========

DUT0 is configured to use NTP authentication.
An NTP server is configured without auth.
Optaining the time should fail due to crypto
failure.

Scenario
========

.. include:: ntpclient/testntpservicewithclientauthenticationonly

.. raw:: html

  <hr>

******************************************************
Test NTP Service With Client And Server Authentication
******************************************************

Description
===========

NTP client and NTP server are configured to use
the same authentication key. Optaining time
information should succeed.

Scenario
========

.. include:: ntpclient/testntpservicewithclientandserverauthentication

.. raw:: html

  <hr>

******************************************
Test NTP Service With Wrong Authentication
******************************************

Description
===========

NTP client and NTP server are configured to use
different authentication key. Optaining time
information should fail.

Scenario
========

.. include:: ntpclient/testntpservicewithwrongauthentication

.. raw:: html
