Configuring VTP
Enabling the VTP Version
VTP version 2 and version 3 are disabled by default.
•
When you enable VTP version 2 on a switch, every VTP version 2-capable switch in the VTP
domain enables version 2. To enable VTP version 3, you must manually configure it on each switch.
•
With VTP versions 1 and 2, you can configure the version only on switches in VTP server or
transparent mode. If a switch is running VTP version 3, you can change to version 2 when the switch
is in client mode if no extended VLANs exist, no private VLANs exist, and no hidden password was
configured.
Caution
VTP version 1 and VTP version 2 are not interoperable on switches in the same VTP domain. Do not
enable VTP version 2 unless every switch in the VTP domain supports version 2.
•
In TrCRF and TrBRF Token ring environments, you must enable VTP version 2 or VTP version 3
for Token Ring VLAN switching to function properly. For Token Ring and Token Ring-Net media,
disable VTP version 2 must be disabled.
•
VTP version 3 is supported on switches running Cisco IOS Release 12.2(52) SE or later.
Caution
In VTP version 3, both the primary and secondary servers can exist on an instance in the domain.
