The default topology is the minimal topology, which includes one OpenFlow kernel switch connected to two hosts, plus the OpenFlow reference controller. Start a minimal topology and enter the CLI: $ sudo mn In Wireshark, click Capture, then Interfaces, then select Start on the loopback interface ( lo).įor now, there should be no OpenFlow packets displayed in the main window.

Remember to do this when you are running X11 clients or running mn -x! Fixing error: “ Could not load the Qt platform plugin "xcb"”Ĭould not load the Qt platform plugin "xcb" it may be because In order to get it to work with (any) X11 clients such as wireshark: $ sudo HOME=~ wireshark & If you are using X11 tunneling with ssh, you may need to pass an additional option to sudo Running Wireshark with X11 tunneling and ssh The xterm terminal emulator, used later in this walkthrough. Setting X11 up correctly will enable you to run other GUI programs and $DISPLAY not set, please consult the FAQ: If Wireshark is installed but you cannot run it (e.g.

You may be able to install both of them using Mininet’s install.sh script System you are using does not have Wireshark and the OpenFlow plugin installed, Wireshark is installed by default in the Mininet VM images. If Wireshark is not installed (command not found error) It is likely that this will not work immediately, so please read the following sections. To view control traffic using the OpenFlow Wireshark dissector, first open wireshark in the background: $ sudo wireshark & This walkthrough will cover typical usage of the majority of options listed. Type the following command to display a help message describing Mininet’s startup options: $ sudo mn -h Let’s get started with Mininet’s startup options. (and then press return, of course!)

The entire walkthrough should take under an hour. The walkthrough assumes that your base system is the Mininet VM, or a native Ubuntu installation with all OpenFlow tools and Mininet installed (this is usually done using Mininet’s install.sh). This walkthrough demonstrates most Mininet commands, as well as its typical usage in concert with the Wireshark dissector.
