When you save VTP information in the switch startup configuration file and
reboot the switch, the switch
configuration is determined as follows:
* If the VTP mode is transparent in the startup configuration and the VLAN
database and the VTP
domain name from the VLAN database matches that in the startup configuration
file, the VLAN
database is ignored (cleared), and the VTP and VLAN configurations in the
startup configuration
file are used. The VLAN database revision number remains unchanged in the
VLAN database.
* If the VTP mode or domain name in the startup configuration do not match
the VLAN database, the
domain name and VTP mode and configuration for the first 1005 VLANs use the
VLAN database
information.
* If the switch is running IOS Release 12.1(9)EA1 or later and you use an
older configuration file to
boot up the switch, the configuration file does not contain VTP or VLAN
information, and the switch
uses the VLAN database configurations.
* If the switch is running an IOS release earlier than 12.1(9)EA1 on the
switch and you use a
configuration file from IOS Release 12.1(9)EA1 or later to boot up the
switch, the image on the
switch does not recognize VLAN and VTP configurations in the configuration
file, so the switch
uses the VLAN database configuration.

be aware of extended vlan support, which is why you could configure vlans in
ios. also when you have configs in vlan database and in ios.. there are some
complications addressed with domain name choosen, i'd recommend using vlan
database if there is no special need like creating vlan 4095.

Absolutely, but mainly when you refer to specific naming. Using the method
Mr. Cameron detailed below, a VLAN #37 will be created with the name
VLAN0037. Not a very descriptive name at all. That's why one would use the
global config or Vlan Database...so they can type in:
vlan 37 name Marketing_Vlan (lame example). Now ya know right away what vlan
37 is being used for!
