v116 v117 229 229 === 3d. Run a traffic duplication controller === 230 230 231 In the above example we ran a very simple learning switch controller. The power of !OpenFlow comes from the fact that you can decide to forward the packet anyway you want based on the supported !OpenFlow actions. A very simple but powerful modification you can do, is to duplicate all the traffic of the switch out a specific port. This is very useful for application and network analysis. You can imagine that at the port where you duplicate traffic you connect a device that does analysis. For this tutorial we are going to verify the duplication by doing `tcpdump s` onports on the OVS switch.231 In the above example we ran a very simple learning switch controller.
