    169169  6. To see messages go between your switch and your controller (listening on port 6633 of your localhost), open a new ssh window to your controller node and run tcpdump on the `eth0` interface:
    170170  {{{
    171   sudo tcpdump -i eth0
     171  sudo tcpdump -i eth0 'port 6633'
    172172  }}}
