Re: vtp question

If what you are trying to do is preprovision/reprovision a known
switch state, then "vlan database" is the way to go AFAIK:

sw#vlan database
% Warning: It is recommended to configure VLAN from config mode,
  as VLAN database mode is being deprecated. Please consult user
  documentation for configuring VTP/VLAN in config mode.

sw(vlan)#show
  VLAN ISL Id: 1
    Name: default
    Media Type: Ethernet
    VLAN 802.10 Id: 100001
    State: Operational
    MTU: 1500
    Backup CRF Mode: Disabled
    Remote SPAN VLAN: No

  VLAN ISL Id: 2
    Name: Lab
...
You'll have to digest this info to reprogram it. I do it using a perl
script and encode it in the same config file as comments like:

! Vlan1: default
! Vlan2: Lab
