2. 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.

2.1. 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:

# 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 --integration
         --test-params 'tunnel_type=vxlan' overlay_p2p_tput

To run GRE encapsulation tests:

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

To run GENEVE encapsulation tests:

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

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

Install the OVS kernel modules

cd src/ovs/ovs
sudo -E make modules_install

Set the following variables:

VSWITCH = 'OvsVanilla'
# 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')]

Run tests:

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

2.2. Executing VXLAN decapsulation tests¶

To run VXLAN decapsulation tests:

Set the variables used in “Executing Tunnel encapsulation tests”
Set dstmac of DUT_NIC2_MAC to the MAC adddress of the 2nd NIC of your DUT

DUT_NIC2_MAC = '<DUT NIC2 MAC>'

Run test:

./vsperf --conf-file user_settings.py --integration overlay_p2p_decap_cont

If you want to use different values for your VXLAN frame, you may set:

VXLAN_FRAME_L3 = {'proto': 'udp',
                  'packetsize': 64,
                  'srcip': TRAFFICGEN_PORT1_IP,
                  '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,
                 }

2.3. Executing GRE decapsulation tests¶

To run GRE decapsulation tests:

Set the variables used in “Executing Tunnel encapsulation tests”
Set dstmac of DUT_NIC2_MAC to the MAC adddress of the 2nd NIC of your DUT

DUT_NIC2_MAC = '<DUT NIC2 MAC>'

Run test:

./vsperf --conf-file user_settings.py --test-params 'tunnel_type=gre'
         --integration overlay_p2p_decap_cont

If you want to use different values for your GRE frame, you may set:

                'packetsize': 64,
                'srcip': TRAFFICGEN_PORT1_IP,
                '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_dstport': 3001,
               }

2.4. Executing GENEVE decapsulation tests¶

IxNet 7.3X does not have native support of GENEVE protocol. The template, GeneveIxNetTemplate.xml_ClearText.xml, should be imported into IxNET for this testcase to work.

To import the template do:

Run the IxNetwork TCL Server
Click on the Traffic menu
Click on the Traffic actions and click Edit Packet Templates
On the Template editor window, click Import. Select the template tools/pkt_gen/ixnet/GeneveIxNetTemplate.xml_ClearText.xml and click import.
Restart the TCL Server.

To run GENEVE decapsulation tests:

Set the variables used in “Executing Tunnel encapsulation tests”
Set dstmac of DUT_NIC2_MAC to the MAC adddress of the 2nd NIC of your DUT

DUT_NIC2_MAC = '<DUT NIC2 MAC>'

Run test:

./vsperf --conf-file user_settings.py --test-params 'tunnel_type=geneve'
         --integration overlay_p2p_decap_cont

If you want to use different values for your GENEVE frame, you may set:

GENEVE_FRAME_L3 = {'proto': 'udp',
                   'packetsize': 64,
                   'srcip': TRAFFICGEN_PORT1_IP,
                   'dstip': '192.168.240.1',
                  }

GENEVE_FRAME_L4 = {'srcport': 6081,
                   'dstport': 6081,
                   'geneve_vni': 0,
