You can disable the sending of DTP frames by also adding to the interface configuration this command: switchport nonegotiate. This will disable the periodic sending of DTP frames to advertise the switch port mode of the local switch. You can view whether a switch port has negotiation disabled in the output of the command above. Very good post, I always use the switchport nonegotiate command to disable the DTP protocol. If possible I also disable the CDP protocol on access ports, because it could also be a possible security hole.
