Chapter 13 Configuring VTP
Configuring VTP
Beginning in privileged EXEC mode, follow these steps to verify and reset the VTP configuration
revision number on a switch before adding it to a VTP domain:
You can also change the VTP domain name by entering the vlan database privileged EXEC command
to enter VLAN database configuration mode and by entering the vtp domain domain-name command.
In this mode, you must enter the exit command to update VLAN information and return to privileged
EXEC mode.
After resetting the configuration revision number, add the switch to the VTP domain.
Note You can use the vtp mode transparent global configuration command or the vtp transparent VLAN
database configuration command to disable VTP on the switch, and then change its VLAN information
without affecting the other switches in the VTP domain.
