Integration tests
=================

VSPERF includes a set of integration tests defined in conf/integration.
These tests can be run by specifying --integration as a parameter to vsperf.
Current tests in conf/integration include switch functionality and Overlay
tests.

Tests in the conf/integration can be used to test scaling of different switch
configurations by adding steps into the test case.

For the overlay tests VSPERF supports VXLAN, GRE and GENEVE tunneling protocols.
Testing of these protocols is limited to unidirectional traffic and
P2P (Physical to Physical scenarios).

NOTE: The configuration for overlay tests provided in this guide is for
unidirectional traffic only.

Executing Integration Tests
---------------------------

To execute integration tests VSPERF is run with the integration parameter. To
view the current test list simply execute the following command:

.. code-block:: console

    ./vsperf --integration --list

The standard tests included are defined inside the
``conf/integration/01_testcases.conf`` file.

Executing Tunnel encapsulation tests
------------------------------------

The VXLAN OVS DPDK encapsulation tests requires IPs, MAC addresses,
bridge names and WHITELIST_NICS for DPDK.

NOTE: Only Ixia traffic generators currently support the execution of the tunnel
encapsulation tests. Support for other traffic generators may come in a future
release.

Default values are already provided. To customize for your environment, override
the following variables in you user_settings.py file:

  .. code-block:: python

    # Variables defined in conf/integration/02_vswitch.conf
    # Tunnel endpoint for Overlay P2P deployment scenario
    # used for br0
    VTEP_IP1 = '192.168.0.1/24'

    # Used as remote_ip in adding OVS tunnel port and
    # to set ARP entry in OVS (e.g. tnl/arp/set br-ext 192.168.240.10 02:00:00:00:00:02
    VTEP_IP2 = '192.168.240.10'

    # Network to use when adding a route for inner frame data
    VTEP_IP2_SUBNET = '192.168.240.0/24'

    # Bridge names
    TUNNEL_INTEGRATION_BRIDGE = 'br0'
    TUNNEL_EXTERNAL_BRIDGE = 'br-ext'

    # IP of br-ext
    TUNNEL_EXTERNAL_BRIDGE_IP = '192.168.240.1/24'

    # vxlan|gre|geneve
    TUNNEL_TYPE = 'vxlan'

    # Variables defined conf/integration/03_traffic.conf
    # For OP2P deployment scenario
    TRAFFICGEN_PORT1_MAC = '02:00:00:00:00:01'
    TRAFFICGEN_PORT2_MAC = '02:00:00:00:00:02'
    TRAFFICGEN_PORT1_IP = '1.1.1.1'
    TRAFFICGEN_PORT2_IP = '192.168.240.10'

To run VXLAN encapsulation tests:

  .. code-block:: console

    ./vsperf --conf-file user_settings.py --integration \
             --test-params 'TUNNEL_TYPE=vxlan' overlay_p2p_tput

To run GRE encapsulation tests:

  .. code-block:: console

    ./vsperf --conf-file user_settings.py --integration \

  .. code-block:: console

    ./vsperf --conf-file user_settings.py --integration \
             --test-params 'TUNNEL_TYPE=geneve' overlay_p2p_tput

To run OVS NATIVE tunnel tests (VXLAN/GRE/GENEVE):

1. Install the OVS kernel modules

  .. code:: console

    cd src/ovs/ovs
    sudo -E make modules_install

2. Set the following variables:

  .. code-block:: python

    VSWITCH = 'OvsVanilla'
    # Specify vport_* kernel module to test.
    PATHS['vswitch']['OvsVanilla']['src']['modules'] = [
        'vport_vxlan',
        'vport_gre',
        'vport_geneve',
        'datapath/linux/openvswitch.ko',
    ]

  **NOTE:** In case, that Vanilla OVS is installed from binary package, then
  please set ``PATHS['vswitch']['OvsVanilla']['bin']['modules']`` instead.

3. Run tests:

  .. code-block:: console

    ./vsperf --conf-file user_settings.py --integration \
             --test-params 'TUNNEL_TYPE=vxlan' overlay_p2p_tput

2. Click on the Traffic menu
3. Click on the Traffic actions and click Edit Packet Templates
4. On the Template editor window, click Import. Select the template
   located at ``3rd_party/ixia/GeneveIxNetTemplate.xml_ClearText.xml``
   and click import.
5. Restart the TCL Server.

Executing Tunnel encapsulation+decapsulation tests
--------------------------------------------------

The OVS DPDK encapsulation_decapsulation tests requires IPs, MAC addresses,
bridge names and WHITELIST_NICS for DPDK.

The test cases can test the tunneling encap and decap without using any ingress
overlay traffic as compared to above test cases. To achieve this the OVS is
configured to perform encap and decap in a series on the same traffic stream as
given below.

TRAFFIC-IN --> [ENCAP] --> [MOD-PKT] --> [DECAP] --> TRAFFIC-OUT


Default values are already provided. To customize for your environment, override
the following variables in you user_settings.py file:

  .. code-block:: python

    # Variables defined in conf/integration/02_vswitch.conf

    # Bridge names
