[c-nsp] VTP issues 3560 to 2950

[Scott Brown]

Hello all! I had VTP working, but now it stopped and nothing changed.  Below
are part of my configs - the first one is my 3560 and the second one is my
2950. I really don't know what details are needed to troubleshoot this, so
if any information is lacking let me know.

 

The VTP server is off of Gi0/1 on the 3560 listed below.
