+TRex Stateless Mode
+===================
+
+TRex can also be run in a stateless mode. For a detailed description of TRex stateless support
+please refer to `TRex Stateless Support <https://trex-tgn.cisco.com/trex/doc/trex_stateless.html>`_.
+
+In this section we show some simple examples using TRex stateless mode. These examples use
+the configuration as shown in the section :ref:`trex`. These examples we will be using VMWare VMs.
+
+To use TRex stateless mode we use 2 terminals on the TRex traffic generator node. One terminal will
+be used for the TRex console and one to monitor the traffic.
+
+In one of terminals start TRex in stateless mode. Use *Ctrl-C* to stop.

+Examples
+========
+
+There are many examples of how to create traffic flows in the directories below the
+TRex root directory. The stateless examples are written in Python and are found in
+the **./stl** directory. Examine the directories **./avl/, ./stl and ./cap2**. A few
+simple examples are as follows:
+
+* ./cap2/dns.yaml - Used in the first example
+* ./avl/sfr_delay_10_1g.yaml - Used in the second example
+* ./cap2/imix*.yaml - Uses some imix traffic profiles.
+* ./stl/udp_1pkt.py - UDP example
+* ./stl/imix.py - Simple imix example
+
+Summary
+=======
+
+This tutorial showed how to download, compile, and install the VPP binary on an
+Intel® Architecture platform. Examples of /etc/sysctl.d/80-vpp.conf and
+/etc/vpp/startup.conf/startup.conf configuration files were provided to get the
+user up and running with VPP. The tutorial also illustrated how to detect and bind
+the network interfaces to a DPDK-compatible driver. You can use the VPP CLI to assign
+IP addresses to these interfaces and bring them up. Four examples using iperf3
+and TRex were included, to show how VPP processes packets in batches. We
+also showed how to use TRex in stateless mode and examine traffic flow statistics.
