Chapter 16 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.
