Configuring VTP
Information About Configuring VTP
VTP version 1 and version 2 support only normal-range VLANs (VLAN IDs 1 to 1005). VTP version 3 supports the entire
VLAN range (VLANs 1 to 4096). Extended range VLANs (VLANs 1006 to 4096) are supported only in VTP version 3. You
cannot convert from VTP version 3 to VTP version 2 if extended VLANs are configured in the domain.
VTP Domain
A VTP domain (also called a VLAN management domain) consists of one switch or several interconnected switches under
the same administrative responsibility sharing the same VTP domain name. A switch can be in only one VTP domain. You
make global VLAN configuration changes for the domain.
By default, the switch is in the VTP no-management-domain state until it receives an advertisement for a domain over a
trunk link (a link that carries the traffic of multiple VLANs) or until you configure a domain name. Until the management
domain name is specified or learned, you cannot create or modify VLANs on a VTP server, and VLAN information is not
propagated over the network.
If the switch receives a VTP advertisement over a trunk link, it inherits the management domain name and the VTP
configuration revision number. The switch then ignores advertisements with a different domain name or an earlier
configuration revision number.
When you make a change to the VLAN configuration on a VTP server, the change is propagated to all switches in the VTP
domain. VTP advertisements are sent over all IEEE trunk connections, including IEEE 802.1Q. VTP dynamically maps
VLANs with unique names and internal index associates across multiple LAN types. Mapping eliminates excessive device
administration required from network administrators.
If you configure a switch for VTP transparent mode, you can create and modify VLANs, but the changes are not sent to
other switches in the domain, and they affect only the individual switch. However, configuration changes made when the
switch is in this mode are saved in the switch running configuration and can be saved to the switch startup configuration
file.
For domain name and password configuration guidelines, see VTP Configuration Guidelines, page 302.
