Adding a VTP Client Switch to a VTP Domain

Follow these steps to verify and reset the VTP configuration revision number on a switch before adding it to
a VTP domain.
Before You Begin
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.
With VTP versions 1 and 2, adding a switch that has a revision number higher than the revision number in
the VTP domain can erase all VLAN information from the VTP server and VTP domain. With VTP version
3, the VLAN information is not erased.
You can use the vtp mode transparent global configuration command to disable VTP on the switch and then
to change its VLAN information without affecting the other switches in the VTP domain.
