Do you need 'sh vlan' output on your switch?

Right; this is the 'problem'.  VTP managed switches require this 
command's output, non-VTP managed switches, well, don't (perhaps). (And 
if you want to use VLAN IDs >1005 you'll setting vtp mode transparent). 
  Commands in write term/show run output are purely static definitions 
(since that only happens when vtp is set transparent and 'extended' 
(full) VLAN range is confiured) (at least on IOS switches).
