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. NOTE: The overlay tests require an IxNet traffic generator. The tunneled traffic is configured by ``ixnetrfc2544v2.tcl`` script. This script can be used with all supported deployment scenarios for generation of frames with VXLAN, GRE or GENEVE protocols. In that case options "Tunnel Operation" and "TRAFFICGEN_IXNET_TCL_SCRIPT" must be properly configured at testcase definition. 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 = 'vsperf-br0' TUNNEL_EXTERNAL_BRIDGE = 'vsperf-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 \ --test-params 'TUNNEL_TYPE=gre' overlay_p2p_tput To run GENEVE encapsulation tests: .. 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.
