Cisco Systems 3560 Manual Do Utilizador

You can configure VTP by using these configuration modes. 

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.

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. 

You can configure all VTP parameters in VLAN database configuration mode, which you access by 
entering the vlan database privileged EXEC command. For more information about available keywords, 
see the vtp VLAN database configuration command description in the command reference for this 
release. When you enter the exit command in VLAN database configuration mode, it applies all the 
commands that you entered and updates the VLAN database. VTP messages are sent to other switches 
in the VTP domain, and the privileged EXEC mode prompt appears. 

If VTP mode is transparent, the domain name and the mode (transparent) are saved in the switch running 
configuration, and you can save this information in the switch startup configuration file by entering the 
copy running-config startup-config privileged EXEC command.
