+
+== Appendix
+
+=== Preparing setup and running the tests.
+
+==== Hardware preparations
+
+Order the UCS with HW described above.
+
+* There are several NICs with this chipset. +
+Bare Intel NICs don't work with Cisco QSFP+ optics, for such case you will need Silicom NICs.
+* Use NICs with 2x40G ports in each.
+* Put the NICs at different NUMAs (first on the left side, second on the right side).
+
+==== Software preparations
+
+* Install the OS (Bare metal Linux, *not* VM!)
+* Obtain the latest TRex package: wget https://trex-tgn.cisco.com/trex/release/latest
+* Untar the package: tar -xzf latest
+* Change dir to unzipped TRex
+* Create config file using command: sudo python dpdk_setup_ports.py -i
+** In case of Ubuntu 16 need python3
+** The script by default produces config for loopback or L2 Switch as DUT (ports connection 1&#8596;2, 3&#8596;4 etc.). +
+If you have router or L3 switch, change the destination MACs of TRex interfaces to match the DUT one's.
+
+==== The tests
+
+* Run the TRex server: sudo ./t-rex-64 -i -c 7
+* In another shell run TRex console: trex-console
+** The console can be run from another computer with -s argument, --help for more info.
+** Other options for TRex client are automation or GUI
+* In the console, run "tui" command, and then send the traffic with commands like:
+** start -f stl/bench.py -m 50% --port 0 3 -t size=590,vm=var1
+** stop
+** clear
+** start -f stl/bench.py -m 30mpps --port 0 -t size=64,vm=cached
+** start -f stl/bench.py -m 100% -t size=1514,vm=random --force
