A network switch, which is participating in VLAN Trunking Protocol (VTP), can have three different modes.
• Server Mode
• Client Mode
• Transparent Mode
VLAN Trunking Protocol (VTP) Server Mode
VLAN Trunking Protocol (VTP) Server mode is the default VTP mode for all Catalyst switches. At least one server is required in a VTP domain to propagate VLAN information within the VTP domain. We can create, add, or delete VLANs of a VTP domain in a Switch which is in VTP Server mode and change VLAN information in a VTP Server. The changes made in a switch in server mode are advertised to the entire VTP domain.
VLAN Trunking Protocol (VTP) Client Mode
VLAN Trunking Protocol (VTP) client mode switches listen to VTP advertisements from other switches and modify their VLAN configurations accordingly. A network switch in VTP client mode requires a server switch to inform it about the VLAN changes. We CANNOT create, add, or delete VLANs in a VTP client.
VLAN Trunking Protocol (VTP) traansparent mode switches do not participate in the VTP domain, but VTP transparent mode switches can receive and forward VTP advertisements through the configured trunk links.
For a small network VLAN configuration and VLAN trunking configuration is easy to manage. But configuring VLAN and VLAN trunking for large networks with many interconnected switches can be a very difficult task. VLAN Trunk Protocol (VTP) is a protocol created by Cisco to create and manage VLANs for a large network with many interconnected switches and to maintain consistency throughout the network. In other words, switches use VLAN trunking protocol (VTP) to communicate among themselves about VLAN configuration.
The VLAN Trunking Protocol (VTP) is a very useful protocol to create, manage and maintain a large network with many interconnected switches. The VLAN Trunking Protocol (VTP) can manage the addition, deletion, and renaming of VLANs from a central point without manual...
