VLAN Trunking Protocol
VTP advertises VLAN configuration information to neighboring switches so that the VLAN
configuration can be made on one switch, with all the other switches in the network learning the
VLAN information dynamically. VTP advertises the VLAN ID, VLAN name, and VLAN type for
each VLAN. However, VTP does not advertise any information about which ports (interfaces)
should be in each VLAN, so the configuration to associate a switch interface with a particular
VLAN (using the switchport access vlan command) must still be configured on each individual
switch. Also, the existence of the VLAN IDs used for private VLANs is advertised, but the rest of
the detailed private VLAN configuration is not advertised by VTP.
