VTP transparent
switches do not participate in VTP. A VTP
transparent
switch does not advertise its VLAN
configuration and does not synchronize its VLAN configuration based on received
advertisements. However, in VTP version 2 or version 3, transparent
switches do forward VTP advertisements that
they receive from other
switches through their trunk interfaces. You
can create, modify, and delete VLANs on a
switch in VTP transparent mode.
In VTP versions 1 and 2, the
switch must be in VTP transparent mode when
you create extended-range VLANs. VTP version 3 also supports creating
extended-range VLANs in client or server mode.
In VTP versions 1 and 2, the
switch must be in VTP transparent mode when
you create private VLANs and when they are configured, you should not change
the VTP mode from transparent to client or server mode. VTP version 3 also
supports private VLANs in client and server modes. When private VLANs are
configured, do not change the VTP mode from transparent to client or server
mode.
When the
switch is in VTP transparent mode, the VTP
and VLAN configurations are saved in NVRAM, but they are not advertised to
other switches. In this mode, VTP mode and domain
name are saved in the
switch running configuration, and you can
save this information in the
switch startup configuration file by using
the
copy running-config startup-config privileged EXEC
command.
In a
switch stack, the running configuration and
the saved configuration are the same for all
switches in a stack.
