| 3 | TRex Stateless Mode |
| 4 | =================== |
| 5 | |
| 6 | TRex can also be run in a stateless mode. For a detailed description of TRex stateless support |
| 7 | please refer to `TRex Stateless Support <https://trex-tgn.cisco.com/trex/doc/trex_stateless.html>`_. |
| 8 | |
| 9 | In this section we show some simple examples using TRex stateless mode. These examples use |
| 10 | the configuration as shown in the section :ref:`trex`. These examples we will be using VMWare VMs. |
| 11 | |
| 12 | To use TRex stateless mode we use 2 terminals on the TRex traffic generator node. One terminal will |
| 13 | be used for the TRex console and one to monitor the traffic. |
| 14 | |
| 15 | In one of terminals start TRex in stateless mode. Use *Ctrl-C* to stop. |
