Switches can operate in any one of the
following three VTP modes:
- Server - If you configure the
switch for server mode, you can create, modify, and delete VLANs,
and specify other configuration parameters (such as VTP version
and VTP pruning) for the entire VTP domain. VTP servers
advertise their VLAN configuration to other switches in the same
VTP domain, and synchronize the VLAN configuration with other
switches based on advertisements received over trunk links. This
is the default mode on the switch.
- Client - VTP clients behave the
same way as VTP servers. However, you cannot create, change, or
delete VLANs on a VTP client.
- Transparent - 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, transparent switches
do forward VTP advertisements that the switches receive out
their trunk ports.
