    - ``--config`` is the path to configuration (if it is not specified,

    - ``--log-dir`` is the path to log files (if it is not specified,
      it is assumed to be ``./log``).
    - ``--pcap-dir`` is the path to the ``.pcap`` files generated for each switch interface
      (if it is not specified, it is assumed to be ``./pcap``).
    - __ verbosity_
    
      ``--verbosity`` specifies the desired verbosity of the output (if it is not specified,
      it is assumed to be set to ``info``). Valid verbosity values are listed `here`__.
    - ``--no-cli`` disables the *Mininet* client (it is enabled by default).
    - ``--clean`` cleans old log files, if specified.
    - ``--clean-dir`` cleans old log files and closes, if specified.
