Configuring VTP
Adding a VTP Client Switch to a VTP Domain
Before adding a VTP client to a VTP domain, always verify that its VTP configuration revision number
is lower than the configuration revision number of the other switches in the VTP domain. Switches in a
VTP domain always use the VLAN configuration of the switch with the highest VTP configuration
revision number. If you add a switch that has a revision number higher than the revision number in the
VTP domain, it can erase all VLAN information from the VTP server and VTP domain.

VTP domain always use the VLAN configuration of the switch with the highest VTP configuration
revision number. If you add a switch that has a revision number higher than the revision number in the

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 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.
to enter VLAN 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
configuration command to disable VTP on the switch, and then change its VLAN information without
affecting the other switches in the VTP domain.

Purpose
Step 1
show vtp status
Check the VTP configuration revision number.
If the number is 0, add the switch to the VTP domain.
If the number is greater than 0, follow these steps:
a.
Write down the domain name.
b.
Write down the configuration revision number.
c.
Continue with the next steps to reset the configuration revision number on the
switch.

Step 2
configure terminal
Enter global configuration mode.
Step 3
vtp domain domain-name
Change the domain name from the original one displayed in Step 1 to a new name.
Step 4
end
The VLAN information on the switch is updated and the configuration revision

Step 5
show vtp status
Verify that the configuration revision number has been reset to 0.
Step 6
configure terminal
Enter global configuration mode.
Step 7
