Right. AUTO has to receive a DTP frame to form a trunk. So, if AUTO and
ON works, then you know that ON is sending DTP frames. Try the same
thing with auto/on (w/ switchport nonegotiate).

  Another way to also think about this is to consider which DTP/Trunk
  methods work with one another.
  
  Does AUTO and ON form a trunk? If so, why?

    Hey Ken,
    
    You might want to consider these 2 questions --
    
    1) Does setting the mode to trunk actually disable DTP?
    
    2) Does disabling DTP on a trunk port disable DTP for the whole

  switch?

    Take it from me, success in the ccie lab requires that you first make

  sure

    you understand what is required. Only then should you configure

  anything.
