```
$ ./VLANHopperDTP.py --help

        :: VLAN Hopping via DTP Trunk negotiation 
        Performs VLAN Hopping via negotiated DTP Trunk / Switch Spoofing technique
        Mariusz B. / mgeeky, '18
        v0.3

usage: ./VLANHopperDTP.py [options]

optional arguments:
  -h, --help            show this help message and exit
  -i DEV, --interface DEV
                        Select interface on which to operate.
  -e CMD, --execute CMD
                        Launch specified command after hopping to new VLAN.
                        One can use one of following placeholders in command:
                        %IFACE (choosen interface), %IP (acquired IP), %NET
                        (net address), %HWADDR (MAC), %GW (gateway), %MASK
                        (full mask), %CIDR (short mask). For instance: -e
                        "arp-scan -I %IFACE %NET%CIDR". May be repeated for
                        more commands. The command will be launched
                        SYNCHRONOUSLY, meaning - one have to append "&" at the
                        end to make the script go along.
  -E CMD, --exit-execute CMD
                        Launch specified command at the end of this script
                        (during cleanup phase).
  -m HWADDR, --mac-address HWADDR
                        Changes MAC address of the interface before and after
                        attack.
  -f, --force           Attempt VLAN Hopping even if DTP was not detected
                        (like in Nonegotiate situation).
  -a, --analyse         Analyse mode: do not create subinterfaces, don't ask
                        for DHCP leases.
  -v, --verbose         Display verbose output.
  -d, --debug           Display debug output.
