How do you deal with a No default OpenFlow controller found for default switch?


*** No default OpenFlow controller found for default switch!


Solution

  • Mininet uses Open vSwitch controller as the default controller, if you omit --controller option.
    If your system/virtual machine does not have it installed, mn command will generate that warning.
    Install ovs-controller or just use --controller=remote to add external controller, like NOX/POX/ODL.
