2. 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.

2.1. 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:

./vsperf --conf-file user_settings.py --run-integration --test-param 'tunnel_type=vxlan' overlay_p2p_tput

To run GRE encapsulation tests:

./vsperf --conf-file user_settings.py --run-integration --test-param 'tunnel_type=gre' overlay_p2p_tput

To run GENEVE encapsulation tests:

./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
cd src/ovs/ovs
sudo -E make modules_install
  1. Set the following variables:
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')]
