Note
to enter VLAN configuration mode and by entering the vtp transparent command, similar to the second
procedure unde the
VLAN configuration command to return the switch to VTP server mode. If extended-range VLANs are
configured on the switch, you cannot change VTP mode to server. You receive an error message, and the
configuration is not allowed.

Enabling VTP Version 2

VTP version 2 is disabled by default on VTP version 2-capable switches. When you enable VTP
version 2 on a switch, every VTP version 2-capable switch in the VTP domain enables version 2. You
can only configure the version on switches in VTP server or transparent mode.
VTP version 1 and VTP version 2 are not interoperable on switches in the same VTP domain. Every
Caution
switch in the VTP domain must use the same VTP version. Do not enable VTP version 2 unless every
switch in the VTP domain supports version 2.
Note In TrCRF and TrBRF Token ring environments, you must enable VTP version 2 for Token Ring VLAN
switching to function properly. For Token Ring and Token Ring-Net media, VTP version 2 must be
disabled.
