| 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. |
| |

| The **-f ./stl/imix.py** argument specifies the file that is used to create the |
| traffic profile. The argument **-p 0 1 2 3** specifies the ports to be used. |
| The argument **-m 9475mbps** the number of packets/sec to be used. |
| All the arguments can be displayed with the **-h** argument. |
| |
| In the other terminal the display shows the statistics related the traffic flows. |
