4.6 VLAN Trunking Protocol (VTP)
4.6.3 VTP modes
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.
