Configuring VTP
Default VTP Configuration
Table 14-2 shows the default VTP configuration.
VTP Configuration Options
You can configure VTP by using these configuration modes.
• VTP Configuration in Global Configuration Mode, page 14-7
•
VTP Configuration in VLAN Database Configuration Mode, page 14-8
You access VLAN database configuration mode by entering the vlan database privileged EXEC
command.
For detailed information about vtp commands, see the command reference for this release.
VTP Configuration in Global Configuration Mode
You can use the vtp global configuration command to set the VTP password, the version, the VTP file
name, the interface providing updated VTP information, the domain name, and the mode, and to disable
or enable pruning. For more information about available keywords, see the command descriptions in the
command reference
for this release. The VTP information is saved in the VTP VLAN database. When
VTP mode is transparent, the VTP domain name and mode are also saved in the switch running
configuration file, and you can save it in the switch startup configuration file by entering the
copy
running-config startup-config privileged EXEC command. You must use this command if you want to
save VTP mode as transparent, even if the switch resets.
When you save VTP information in the switch startup configuration file and reboot the switch, the switch
configuration is selected 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.
