v94 v95 169 169 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: 170 170 {{{ 171 sudo tcpdump -i eth0 171 sudo tcpdump -i eth0 'port 6633' 172 172 }}} 173 173 You will see (1) periodic keepalive messages being exchanged by the switch and the controller, (2) messages from the switch to the controller (e.g. when there is a table miss) and an ICMP Echo message in, and (3) messages from the controller to the switch (e.g. to install new flow entries).
