Integration tests ================= VSPERF includes a set of integration tests defined in conf/integration. These tests can be run by specifying --run-integration as a parameter to vsperf. Current tests in conf/integration are Overlay tests. Executing Tunnel encapsulation tests ------------------------------------ VSPERF supports VXLAN, GRE and GENEVE tunneling protocols. Testing of these protocols is limited to unidirectional traffic and P2P (Physical to Physical scenarios). 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: # 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 --run-integration --test-param 'tunnel_type=vxlan' overlay_p2p_tput To run GRE encapsulation tests: .. code-block:: console ./vsperf --conf-file user_settings.py --run-integration --test-param 'tunnel_type=gre' overlay_p2p_tput To run GENEVE encapsulation tests: .. code-block:: console ./vsperf --conf-file user_settings.py --run-integration --test-param '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:: console VSWITCH = 'OvsVanilla' VSWITCH_VANILLA_PHY_PORT_NAMES = ['nic1name', 'nic2name'] # Specify vport_* kernel module to test. VSWITCH_VANILLA_KERNEL_MODULES = ['vport_vxlan', 'vport_gre', 'vport_geneve', os.path.join(OVS_DIR_VANILLA, 'datapath/linux/openvswitch.ko')] 3. Run tests: .. code-block:: console ./vsperf --conf-file user_settings.py --run-integration --test-param 'tunnel_type=vxlan' overlay_p2p_tput Executing VXLAN decapsulation tests ------------------------------------ To run VXLAN decapsulation tests: 1. Set the variables used in "Executing Tunnel encapsulation tests" 2. Set IXNET_TCL_SCRIPT, VXLAN_FRAME_L2, VLXAN_FRAME_L3 and DUT_NIC1_MAC of your settings file to: .. code-block:: console IXNET_TCL_SCRIPT='ixnetrfc2544v2.tcl' VXLAN_FRAME_L2 = {'srcmac': '01:02:03:04:05:06', 'dstmac': '', } VXLAN_FRAME_L3 = {'proto': 'udp', 'packetsize': 64, 'srcip': '1.1.1.1', 'dstip': '192.168.240.1', } VXLAN_FRAME_L4 = {'srcport': 4789, 'dstport': 4789, 'vni': VXLAN_VNI, 'inner_srcmac': '01:02:03:04:05:06', 'inner_dstmac': '06:05:04:03:02:01', 'inner_srcip': '192.168.0.10', 'inner_dstip': '192.168.240.9', 'inner_proto': 'udp', 'inner_srcport': 3000, 'inner_dstport': 3001, } # The receiving NIC of VXLAN traffic DUT_NIC1_MAC = '' 3. Run test: .. code-block:: console ./vsperf --conf-file user_settings.py --run-integration overlay_p2p_decap_cont Executing GRE decapsulation tests --------------------------------- To run GRE decapsulation tests: 1. Set the variables used in "Executing Tunnel encapsulation tests" 2. Set IXNET_TCL_SCRIPT, GRE_FRAME_L2, GRE_FRAME_L3 and DUT_NIC1_MAC of your settings file to: .. code-block:: console IXNET_TCL_SCRIPT='ixnetrfc2544v2.tcl' GRE_FRAME_L2 = {'srcmac': '01:02:03:04:05:06', 'dstmac': '', } GRE_FRAME_L3 = {'proto': 'gre', 'packetsize': 64, 'srcip': '1.1.1.1', 'dstip': '192.168.240.1', } GRE_FRAME_L4 = {'srcport': 0, 'dstport': 0 'inner_srcmac': '01:02:03:04:05:06', 'inner_dstmac': '06:05:04:03:02:01', 'inner_srcip': '192.168.0.10', 'inner_dstip': '192.168.240.9', 'inner_proto': 'udp', 'inner_srcport': 3000, 'inner_dstport': 3001, } # The receiving NIC of GRE traffic DUT_NIC1_MAC = '' 3.

The template, GeneveIxNetTemplate.xml_ClearText.xml, should be imported into IxNET for this testcase to work. To import the template do: 1. Run the IxNetwork TCL Server 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 tools/pkt_gen/ixnet/GeneveIxNetTemplate.xml_ClearText.xml and click import. To run GENEVE decapsulation tests: 1. Set the variables used in "Executing Tunnel encapsulation tests" 2. Set IXNET_TCL_SCRIPT, GENEVE_FRAME_L2, GENEVE_FRAME_L3 and DUT_NIC1_MAC of your settings file to: .. code-block:: console IXNET_TCL_SCRIPT='ixnetrfc2544v2.tcl' GENEVE_FRAME_L2 = {'srcmac': '01:02:03:04:05:06', 'dstmac': '', } GENEVE_FRAME_L3 = {'proto': 'udp', 'packetsize': 64, 'srcip': '1.1.1.1', 'dstip': '192.168.240.1', 'geneve_vni': 0, 'inner_srcmac': '01:02:03:04:05:06', 'inner_dstmac': '06:05:04:03:02:01', 'inner_srcip': '192.168.0.10', 'inner_dstip': '192.168.240.9', 'inner_proto': 'udp', 'inner_srcport': 3000, 'inner_dstport': 3001, } GENEVE_FRAME_L4 = {'srcport': 6081, 'dstport': 6081, 'geneve_vni': 0, 'inner_srcmac': '01:02:03:04:05:06', 'inner_dstmac': '06:05:04:03:02:01', 'inner_srcip': '192.168.0.10', 'inner_dstip': '192.168.240.9', 'inner_proto': 'udp', 'inner_srcport': 3000, 'inner_dstport': 3001, } # The receiving NIC of GENEVE traffic DUT_NIC1_MAC = '' 3.
