Mininet openflow tutorial

I am new to mininet and trying to follow the tutorial on mininet/openflow https://github.com/mininet/openflow-tutorial/wiki/Learn-Development-Tools

I have a problem with the Wireshark capture, it's only capturing TCP packets on the lo interface, no OpenFlow packets at all.

any idea what might be wrong?

Cheers, ami

Solution

  • I think you use openflow on port 6634 but as you can see here in wireshark documentation it expects to see OpenFlow packets on port 6633 or 6653.

    I prefer to use third party controller but if you want to use mininet default controller, you can set its port with:

    sudo controller ptcp:6653
