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