 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 a `tcpdump`  on a port on the OVS switch. 
 
-  1. Use the interfaces that are connected to `host2` and  `host3`. If you haven't note them down you can use the manifest and the MAC address of the interfaces (ovs:if1 and ovs:if2) to figure this out.  Run tcpdump on these interfaces; one in each of the other two terminals you opened. This will allow you to see all traffic going out the interfaces.
