+'vsperf' Traffic Gen Guide
+===========================
+
+Overview
+--------
+
+VSPERF supports the following traffic generators:
+
+ * Dummy_ (DEFAULT)
+ * Ixia_
+ * `Spirent TestCenter`_
+ * `Xena Networks`_
+ * MoonGen_
+
+To see the list of traffic gens from the cli:
+
+.. code-block:: console
+
+ $ ./vsperf --list-trafficgens
+
+This guide provides the details of how to install
+and configure the various traffic generators.
+
+Background Information
+----------------------
+The traffic default configuration can be found in **conf/03_traffic.conf**,
+and is configured as follows:
+
+.. code-block:: console
+
+ TRAFFIC = {
+ 'traffic_type' : 'rfc2544_throughput',
+ 'frame_rate' : 100,
+ 'bidir' : 'True', # will be passed as string in title format to tgen
+ 'multistream' : 0,
+ 'stream_type' : 'L4',
+ 'pre_installed_flows' : 'No', # used by vswitch implementation
+ 'flow_type' : 'port', # used by vswitch implementation
+
+ 'l2': {
+ 'framesize': 64,
+ 'srcmac': '00:00:00:00:00:00',
+ 'dstmac': '00:00:00:00:00:00',
+ },
+ 'l3': {
+ 'proto': 'udp',
+ 'srcip': '1.1.1.1',
+ 'dstip': '90.90.90.90',
+ },
+ 'l4': {
+ 'srcport': 3000,
+ 'dstport': 3001,
+ },
+ 'vlan': {
+ 'enabled': False,
+ 'id': 0,
+ 'priority': 0,
+ 'cfi': 0,
+ },
+ }
+
+The framesize parameter can be overridden from the configuration
+files by adding the following to your custom configuration file
+``10_custom.conf``:
+
+.. code-block:: console
+
+ TRAFFICGEN_PKT_SIZES = (64, 128,)
+
+OR from the commandline:
+
+.. code-block:: console
+
+ $ ./vsperf --test-params "TRAFFICGEN_PKT_SIZES=(x,y)" $TESTNAME
+
+You can also modify the traffic transmission duration and the number
+of tests run by the traffic generator by extending the example
+commandline above to:
+
+.. code-block:: console
+
+ $ ./vsperf --test-params "TRAFFICGEN_PKT_SIZES=(x,y);TRAFFICGEN_DURATION=10;" \
+ "TRAFFICGEN_RFC2544_TESTS=1" $TESTNAME
+
+.. _trafficgen-dummy:
+
+Dummy
+-----
+
+The Dummy traffic generator can be used to test VSPERF installation or
+to demonstrate VSPERF functionality at DUT without connection
+to a real traffic generator.
+
+You could also use the Dummy generator in case, that your external
+traffic generator is not supported by VSPERF. In such case you could
+use VSPERF to setup your test scenario and then transmit the traffic.
+After the transmission is completed you could specify values for all
+collected metrics and VSPERF will use them to generate final reports.
+
+Setup
+~~~~~
+
+To select the Dummy generator please add the following to your
+custom configuration file ``10_custom.conf``.
+
+.. code-block:: console
+
+ TRAFFICGEN = 'Dummy'
+
+OR run ``vsperf`` with the ``--trafficgen`` argument
+
+.. code-block:: console
+
+ $ ./vsperf --trafficgen Dummy $TESTNAME
+
+Where $TESTNAME is the name of the vsperf test you would like to run.
+This will setup the vSwitch and the VNF (if one is part of your test)
+print the traffic configuration and prompt you to transmit traffic
+when the setup is complete.
+
+.. code-block:: console
+
+ Please send 'continuous' traffic with the following stream config:
+ 30mS, 90mpps, multistream False
+ and the following flow config:
+ {
+ "flow_type": "port",
+ "l3": {
+ "srcip": "1.1.1.1",
+ "proto": "tcp",
+ "dstip": "90.90.90.90"
+ },
+ "traffic_type": "rfc2544_continuous",
+ "multistream": 0,
+ "bidir": "True",
+ "vlan": {
+ "cfi": 0,
+ "priority": 0,
+ "id": 0,
+ "enabled": false
+ },
+ "frame_rate": 90,
+ "l2": {
+ "dstport": 3001,
+ "srcport": 3000,
+ "dstmac": "00:00:00:00:00:00",
+ "srcmac": "00:00:00:00:00:00",
+ "framesize": 64
+ }
+ }
+ What was the result for 'frames tx'?
+
+When your traffic generator has completed traffic transmission and provided
+the results please input these at the VSPERF prompt. VSPERF will try
+to verify the input:
+
+.. code-block:: console
+
+ Is '$input_value' correct?
+
+Please answer with y OR n.
+
+VSPERF will ask you to provide a value for every of collected metrics. The list
+of metrics can be found at traffic-type-metrics_.
+Finally vsperf will print out the results for your test and generate the
+appropriate logs and report files.
+
+.. _traffic-type-metrics:
+
+Metrics collected for supported traffic types
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Below you could find a list of metrics collected by VSPERF for each of supported
+traffic types.
+
+RFC2544 Throughput and Continuous:
+
+ * frames tx
+ * frames rx
+ * min latency
+ * max latency
+ * avg latency
+ * frameloss
+
+RFC2544 Back2back:
+
+ * b2b frames
+ * b2b frame loss %
+
+Dummy result pre-configuration
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In case of a Dummy traffic generator it is possible to pre-configure the test
+results. This is useful for creation of demo testcases, which do not require
+a real traffic generator. Such testcase can be run by any user and it will still
+generate all reports and result files.
+
+Result values can be specified within ``TRAFFICGEN_DUMMY_RESULTS`` dictionary,
+where every of collected metrics must be properly defined. Please check the list
+of traffic-type-metrics_.
+
+Dictionary with dummy results can be passed by CLI argument ``--test-params``
+or specified in ``Parameters`` section of testcase definition.
+
+Example of testcase execution with dummy results defined by CLI argument:
+
+.. code-block:: console
+
+ $ ./vsperf back2back --trafficgen Dummy --test-params \
+ "TRAFFICGEN_DUMMY_RESULTS={'b2b frames':'3000','b2b frame loss %':'0.0'}"
+
+Example of testcase definition with pre-configured dummy results:
+
+.. code-block:: python
+
+ {
+ "Name": "back2back",
+ "Traffic Type": "rfc2544_back2back",
+ "Deployment": "p2p",
+ "biDirectional": "True",
+ "Description": "LTD.Throughput.RFC2544.BackToBackFrames",
+ "Parameters" : {
+ 'TRAFFICGEN_DUMMY_RESULTS' : {'b2b frames':'3000','b2b frame loss %':'0.0'}
+ },
+ },
+
+**NOTE:** Pre-configured results for the Dummy traffic generator will be used only
+in case, that the Dummy traffic generator is used. Otherwise the option
+``TRAFFICGEN_DUMMY_RESULTS`` will be ignored.
+
+.. _Ixia:
+
+Ixia
+----
+
+VSPERF can use both IxNetwork and IxExplorer TCL servers to control Ixia chassis.
+However usage of IxNetwork TCL server is a preferred option. Following sections
+will describe installation and configuration of IxNetwork components used by VSPERF.
+
+Installation
+~~~~~~~~~~~~
+
+On the system under the test you need to install IxNetworkTclClient$(VER\_NUM)Linux.bin.tgz.
+
+On the IXIA client software system you need to install IxNetwork TCL server. After its
+installation you should configure it as follows:
+
+ 1. Find the IxNetwork TCL server app (start -> All Programs -> IXIA ->
+ IxNetwork -> IxNetwork\_$(VER\_NUM) -> IxNetwork TCL Server)
+ 2. Right click on IxNetwork TCL Server, select properties - Under shortcut tab in
+ the Target dialogue box make sure there is the argument "-tclport xxxx"
+ where xxxx is your port number (take note of this port number as you will
+ need it for the 10\_custom.conf file).
+
+ .. image:: TCLServerProperties.png
+
+ 3. Hit Ok and start the TCL server application
+
+VSPERF configuration
+~~~~~~~~~~~~~~~~~~~~
+
+There are several configuration options specific to the IxNetwork traffic generator
+from IXIA. It is essential to set them correctly, before the VSPERF is executed
+for the first time.
+
+Detailed description of options follows:
+
+ * ``TRAFFICGEN_IXNET_MACHINE`` - IP address of server, where IxNetwork TCL Server is running
+ * ``TRAFFICGEN_IXNET_PORT`` - PORT, where IxNetwork TCL Server is accepting connections from
+ TCL clients
+ * ``TRAFFICGEN_IXNET_USER`` - username, which will be used during communication with IxNetwork
+ TCL Server and IXIA chassis
+ * ``TRAFFICGEN_IXIA_HOST`` - IP address of IXIA traffic generator chassis
+ * ``TRAFFICGEN_IXIA_CARD`` - identification of card with dedicated ports at IXIA chassis
+ * ``TRAFFICGEN_IXIA_PORT1`` - identification of the first dedicated port at ``TRAFFICGEN_IXIA_CARD``
+ at IXIA chassis; VSPERF uses two separated ports for traffic generation. In case of
+ unidirectional traffic, it is essential to correctly connect 1st IXIA port to the 1st NIC
+ at DUT, i.e. to the first PCI handle from ``WHITELIST_NICS`` list. Otherwise traffic may not
+ be able to pass through the vSwitch.
+ * ``TRAFFICGEN_IXIA_PORT2`` - identification of the second dedicated port at ``TRAFFICGEN_IXIA_CARD``
+ at IXIA chassis; VSPERF uses two separated ports for traffic generation. In case of
+ unidirectional traffic, it is essential to correctly connect 2nd IXIA port to the 2nd NIC
+ at DUT, i.e. to the second PCI handle from ``WHITELIST_NICS`` list. Otherwise traffic may not
+ be able to pass through the vSwitch.
+ * ``TRAFFICGEN_IXNET_LIB_PATH`` - path to the DUT specific installation of IxNetwork TCL API
+ * ``TRAFFICGEN_IXNET_TCL_SCRIPT`` - name of the TCL script, which VSPERF will use for
+ communication with IXIA TCL server
+ * ``TRAFFICGEN_IXNET_TESTER_RESULT_DIR`` - folder accessible from IxNetwork TCL server,
+ where test results are stored, e.g. ``c:/ixia_results``; see test-results-share_
+ * ``TRAFFICGEN_IXNET_DUT_RESULT_DIR`` - directory accessible from the DUT, where test
+ results from IxNetwork TCL server are stored, e.g. ``/mnt/ixia_results``; see
+ test-results-share_
+
+.. _test-results-share:
+
+Test results share
+~~~~~~~~~~~~~~~~~~
+
+VSPERF is not able to retrieve test results via TCL API directly. Instead, all test
+results are stored at IxNetwork TCL server. Results are stored at folder defined by
+``TRAFFICGEN_IXNET_TESTER_RESULT_DIR`` configuration parameter. Content of this
+folder must be shared (e.g. via samba protocol) between TCL Server and DUT, where
+VSPERF is executed. VSPERF expects, that test results will be available at directory
+configured by ``TRAFFICGEN_IXNET_DUT_RESULT_DIR`` configuration parameter.
+
+Example of sharing configuration:
+
+ * Create a new folder at IxNetwork TCL server machine, e.g. ``c:\ixia_results``
+ * Modify sharing options of ``ixia_results`` folder to share it with everybody
+ * Create a new directory at DUT, where shared directory with results
+ will be mounted, e.g. ``/mnt/ixia_results``
+ * Update your custom VSPERF configuration file as follows:
+
+ .. code-block:: python
+
+ TRAFFICGEN_IXNET_TESTER_RESULT_DIR = 'c:/ixia_results'
+ TRAFFICGEN_IXNET_DUT_RESULT_DIR = '/mnt/ixia_results'
+
+ **NOTE:** It is essential to use slashes '/' also in path
+ configured by ``TRAFFICGEN_IXNET_TESTER_RESULT_DIR`` parameter.
+ * Install cifs-utils package.
+
+ e.g. at rpm based Linux distribution:
+
+ .. code-block:: console
+
+ yum install cifs-utils
+
+ * Mount shared directory, so VSPERF can access test results.
+
+ e.g. by adding new record into ``/etc/fstab``
+
+ .. code-block:: console
+
+ mount -t cifs //_TCL_SERVER_IP_OR_FQDN_/ixia_results /mnt/ixia_results
+ -o file_mode=0777,dir_mode=0777,nounix
+
+It is recommended to verify, that any new file inserted into ``c:/ixia_results`` folder
+is visible at DUT inside ``/mnt/ixia_results`` directory.
+
+.. _`Spirent TestCenter`:
+
+Spirent Setup
+-------------
+
+Spirent installation files and instructions are available on the
+Spirent support website at:
+
+http://support.spirent.com
+
+Select a version of Spirent TestCenter software to utilize. This example
+will use Spirent TestCenter v4.57 as an example. Substitute the appropriate
+version in place of 'v4.57' in the examples, below.
+
+On the CentOS 7 System
+~~~~~~~~~~~~~~~~~~~~~~
+
+Download and install the following:
+
+Spirent TestCenter Application, v4.57 for 64-bit Linux Client
+
+Spirent Virtual Deployment Service (VDS)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Spirent VDS is required for both TestCenter hardware and virtual
+chassis in the vsperf environment. For installation, select the version
+that matches the Spirent TestCenter Application version. For v4.57,
+the matching VDS version is 1.0.55. Download either the ova (VMware)
+or qcow2 (QEMU) image and create a VM with it. Initialize the VM
+according to Spirent installation instructions.
+
+Using Spirent TestCenter Virtual (STCv)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+STCv is available in both ova (VMware) and qcow2 (QEMU) formats. For
+VMware, download:
+
+Spirent TestCenter Virtual Machine for VMware, v4.57 for Hypervisor - VMware ESX.ESXi
+
+Virtual test port performance is affected by the hypervisor configuration. For
+best practice results in deploying STCv, the following is suggested:
+
+- Create a single VM with two test ports rather than two VMs with one port each
+- Set STCv in DPDK mode
+- Give STCv 2*n + 1 cores, where n = the number of ports. For vsperf, cores = 5.
+- Turning off hyperthreading and pinning these cores will improve performance
+- Give STCv 2 GB of RAM
+
+To get the highest performance and accuracy, Spirent TestCenter hardware is
+recommended. vsperf can run with either stype test ports.
+
+Using STC REST Client
+~~~~~~~~~~~~~~~~~~~~~
+The stcrestclient package provides the stchttp.py ReST API wrapper module.
+This allows simple function calls, nearly identical to those provided by
+StcPython.py, to be used to access TestCenter server sessions via the
+STC ReST API. Basic ReST functionality is provided by the resthttp module,
+and may be used for writing ReST clients independent of STC.
+
+- Project page: <https://github.com/Spirent/py-stcrestclient>
+- Package download: <http://pypi.python.org/pypi/stcrestclient>
+
+To use REST interface, follow the instructions in the Project page to
+install the package. Once installed, the scripts named with 'rest' keyword
+can be used. For example: testcenter-rfc2544-rest.py can be used to run
+RFC 2544 tests using the REST interface.
+
+Configuration:
+~~~~~~~~~~~~~~
+
+1. The Labserver and license server addresses. These parameters applies to
+ all the tests, and are mandatory for all tests.
+
+.. code-block:: console
+
+ TRAFFICGEN_STC_LAB_SERVER_ADDR = " "
+ TRAFFICGEN_STC_LICENSE_SERVER_ADDR = " "
+ TRAFFICGEN_STC_PYTHON2_PATH = " "
+ TRAFFICGEN_STC_TESTCENTER_PATH = " "
+ TRAFFICGEN_STC_TEST_SESSION_NAME = " "
+ TRAFFICGEN_STC_CSV_RESULTS_FILE_PREFIX = " "
+
+2. For RFC2544 tests, the following parameters are mandatory
+
+.. code-block:: console
+
+ TRAFFICGEN_STC_EAST_CHASSIS_ADDR = " "
+ TRAFFICGEN_STC_EAST_SLOT_NUM = " "
+ TRAFFICGEN_STC_EAST_PORT_NUM = " "
+ TRAFFICGEN_STC_EAST_INTF_ADDR = " "
+ TRAFFICGEN_STC_EAST_INTF_GATEWAY_ADDR = " "
+ TRAFFICGEN_STC_WEST_CHASSIS_ADDR = ""
+ TRAFFICGEN_STC_WEST_SLOT_NUM = " "
+ TRAFFICGEN_STC_WEST_PORT_NUM = " "
+ TRAFFICGEN_STC_WEST_INTF_ADDR = " "
+ TRAFFICGEN_STC_WEST_INTF_GATEWAY_ADDR = " "
+ TRAFFICGEN_STC_RFC2544_TPUT_TEST_FILE_NAME
+
+3. RFC2889 tests: Currently, the forwarding, address-caching, and
+ address-learning-rate tests of RFC2889 are supported.
+ The testcenter-rfc2889-rest.py script implements the rfc2889 tests.
+ The configuration for RFC2889 involves test-case definition, and parameter
+ definition, as described below. New results-constants, as shown below, are
+ added to support these tests.
+
+Example of testcase definition for RFC2889 tests:
+
+.. code-block:: python
+
+ {
+ "Name": "phy2phy_forwarding",
+ "Deployment": "p2p",
+ "Description": "LTD.Forwarding.RFC2889.MaxForwardingRate",
+ "Parameters" : {
+ "TRAFFIC" : {
+ "traffic_type" : "rfc2889_forwarding",
+ },
+ },
+ }
+
+For RFC2889 tests, specifying the locations for the monitoring ports is mandatory.
+Necessary parameters are:
+
+.. code-block:: console
+
+ TRAFFICGEN_STC_RFC2889_TEST_FILE_NAME
+ TRAFFICGEN_STC_EAST_CHASSIS_ADDR = " "
+ TRAFFICGEN_STC_EAST_SLOT_NUM = " "
+ TRAFFICGEN_STC_EAST_PORT_NUM = " "
+ TRAFFICGEN_STC_EAST_INTF_ADDR = " "
+ TRAFFICGEN_STC_EAST_INTF_GATEWAY_ADDR = " "
+ TRAFFICGEN_STC_WEST_CHASSIS_ADDR = ""
+ TRAFFICGEN_STC_WEST_SLOT_NUM = " "
+ TRAFFICGEN_STC_WEST_PORT_NUM = " "
+ TRAFFICGEN_STC_WEST_INTF_ADDR = " "
+ TRAFFICGEN_STC_WEST_INTF_GATEWAY_ADDR = " "
+ TRAFFICGEN_STC_VERBOSE = "True"
+ TRAFFICGEN_STC_RFC2889_LOCATIONS="//10.1.1.1/1/1,//10.1.1.1/2/2"
+
+Other Configurations are :
+
+.. code-block:: console
+
+ TRAFFICGEN_STC_RFC2889_MIN_LR = 1488
+ TRAFFICGEN_STC_RFC2889_MAX_LR = 14880
+ TRAFFICGEN_STC_RFC2889_MIN_ADDRS = 1000
+ TRAFFICGEN_STC_RFC2889_MAX_ADDRS = 65536
+ TRAFFICGEN_STC_RFC2889_AC_LR = 1000
+
+The first 2 values are for address-learning test where as other 3 values are
+for the Address caching capacity test. LR: Learning Rate. AC: Address Caching.
+Maximum value for address is 16777216. Whereas, maximum for LR is 4294967295.
+
+Results for RFC2889 Tests: Forwarding tests outputs following values:
+
+.. code-block:: console
+
+ TX_RATE_FPS : "Transmission Rate in Frames/sec"
+ THROUGHPUT_RX_FPS: "Received Throughput Frames/sec"
+ TX_RATE_MBPS : " Transmission rate in MBPS"
+ THROUGHPUT_RX_MBPS: "Received Throughput in MBPS"
+ TX_RATE_PERCENT: "Transmission Rate in Percentage"
+ FRAME_LOSS_PERCENT: "Frame loss in Percentage"
+ FORWARDING_RATE_FPS: " Maximum Forwarding Rate in FPS"
+
+
+Whereas, the address caching test outputs following values,
+
+.. code-block:: console
+
+ CACHING_CAPACITY_ADDRS = 'Number of address it can cache'
+ ADDR_LEARNED_PERCENT = 'Percentage of address successfully learned'
+
+and address learning test outputs just a single value:
+
+.. code-block:: console
+
+ OPTIMAL_LEARNING_RATE_FPS = 'Optimal learning rate in fps'
+
+Note that 'FORWARDING_RATE_FPS', 'CACHING_CAPACITY_ADDRS',
+'ADDR_LEARNED_PERCENT' and 'OPTIMAL_LEARNING_RATE_FPS' are the new
+result-constants added to support RFC2889 tests.
+
+.. _`Xena Networks`:
+
+Xena Networks
+-------------
+
+Installation
+~~~~~~~~~~~~
+
+Xena Networks traffic generator requires specific files and packages to be
+installed. It is assumed the user has access to the Xena2544.exe file which
+must be placed in VSPerf installation location under the tools/pkt_gen/xena
+folder. Contact Xena Networks for the latest version of this file. The user
+can also visit www.xenanetworks/downloads to obtain the file with a valid
+support contract.
+
+**Note** VSPerf has been fully tested with version v2.43 of Xena2544.exe
+
+To execute the Xena2544.exe file under Linux distributions the mono-complete
+package must be installed. To install this package follow the instructions
+below. Further information can be obtained from
+http://www.mono-project.com/docs/getting-started/install/linux/
+
+.. code-block:: console
+
+ rpm --import "http://keyserver.ubuntu.com/pks/lookup?op=get&search=0x3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF"
+ yum-config-manager --add-repo http://download.mono-project.com/repo/centos/
+ yum -y install mono-complete
+
+To prevent gpg errors on future yum installation of packages the mono-project
+repo should be disabled once installed.
+
+.. code-block:: console
+
+ yum-config-manager --disable download.mono-project.com_repo_centos_
+
+Configuration
+~~~~~~~~~~~~~
+
+Connection information for your Xena Chassis must be supplied inside the
+``10_custom.conf`` or ``03_custom.conf`` file. The following parameters must be
+set to allow for proper connections to the chassis.
+
+.. code-block:: console
+
+ TRAFFICGEN_XENA_IP = ''
+ TRAFFICGEN_XENA_PORT1 = ''
+ TRAFFICGEN_XENA_PORT2 = ''
+ TRAFFICGEN_XENA_USER = ''
+ TRAFFICGEN_XENA_PASSWORD = ''
+ TRAFFICGEN_XENA_MODULE1 = ''
+ TRAFFICGEN_XENA_MODULE2 = ''
+
+RFC2544 Throughput Testing
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Xena traffic generator testing for rfc2544 throughput can be modified for
+different behaviors if needed. The default options for the following are
+optimized for best results.
+
+.. code-block:: console
+
+ TRAFFICGEN_XENA_2544_TPUT_INIT_VALUE = '10.0'
+ TRAFFICGEN_XENA_2544_TPUT_MIN_VALUE = '0.1'
+ TRAFFICGEN_XENA_2544_TPUT_MAX_VALUE = '100.0'
+ TRAFFICGEN_XENA_2544_TPUT_VALUE_RESOLUTION = '0.5'
+ TRAFFICGEN_XENA_2544_TPUT_USEPASS_THRESHHOLD = 'false'
+ TRAFFICGEN_XENA_2544_TPUT_PASS_THRESHHOLD = '0.0'
+
+Each value modifies the behavior of rfc 2544 throughput testing. Refer to your
+Xena documentation to understand the behavior changes in modifying these
+values.
+
+Continuous Traffic Testing
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Xena continuous traffic by default does a 3 second learning preemption to allow
+the DUT to receive learning packets before a continuous test is performed. If
+a custom test case requires this learning be disabled, you can disable the option
+or modify the length of the learning by modifying the following settings.
+
+.. code-block:: console
+
+ TRAFFICGEN_XENA_CONT_PORT_LEARNING_ENABLED = False
+ TRAFFICGEN_XENA_CONT_PORT_LEARNING_DURATION = 3
+
+MoonGen
+-------
+
+Installation
+~~~~~~~~~~~~
+
+MoonGen architecture overview and general installation instructions
+can be found here:
+
+https://github.com/emmericp/MoonGen
+
+* Note: Today, MoonGen with VSPERF only supports 10Gbps line speeds.
+
+For VSPERF use, MoonGen should be cloned from here (as opposed to the
+previously mentioned GitHub):
+
+git clone https://github.com/atheurer/lua-trafficgen
+
+and use the master branch:
+
+git checkout master
+
+VSPERF uses a particular Lua script with the MoonGen project:
+
+trafficgen.lua
+
+Follow MoonGen set up and execution instructions here:
+
+https://github.com/atheurer/lua-trafficgen/blob/master/README.md
+
+Note one will need to set up ssh login to not use passwords between the server
+running MoonGen and the device under test (running the VSPERF test
+infrastructure). This is because VSPERF on one server uses 'ssh' to
+configure and run MoonGen upon the other server.
+
+One can set up this ssh access by doing the following on both servers:
+
+.. code-block:: console
+
+ ssh-keygen -b 2048 -t rsa
+ ssh-copy-id <other server>
+
+Configuration
+~~~~~~~~~~~~~
+
+Connection information for MoonGen must be supplied inside the
+``10_custom.conf`` or ``03_custom.conf`` file. The following parameters must be
+set to allow for proper connections to the host with MoonGen.
+
+.. code-block:: console
+
+ TRAFFICGEN_MOONGEN_HOST_IP_ADDR = ""
+ TRAFFICGEN_MOONGEN_USER = ""
+ TRAFFICGEN_MOONGEN_BASE_DIR = ""
+ TRAFFICGEN_MOONGEN_PORTS = ""
+ TRAFFICGEN_MOONGEN_LINE_SPEED_GBPS = ""
