   1. Use the interfaces that are connected to `host2` and  `host3`. 
-
-   Software Switch (OVS): 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 two ovs terminals you opened. This will allow you to see all traffic going out the interfaces.

-   Hardware Switch:   Refer to this Section: [http://groups.geni.net/geni/wiki/GENIExperimenter/Tutorials/OpenFlowOVS/Appendix#Usefultips UsefulTips]

If you are using a hardware switch, you may not see the traffic on host3, but if you observe your controller output, you will notice that flows are being installed for forwarding to host2 and host3.[[BR]]
+   To see that duplication is happening, on host3, run:  
   {{{
   sudo tcpdump -i <data_interface_name>
   }}}
 
+  You should see ICMP echo and ICMP reply lines from host1 to host2 showing up in the host3 tcpdump window.
   2. In the controller host directory `/tmp/pox/ext` you would see two files:
