VTP (VLAN Trunking Protocol) supports two main trunking protocols: IEEE 802.1Q and Cisco's proprietary ISL (Inter-Switch Link). IEEE 802.1Q is the industry standard for VLAN tagging, while ISL is specific to Cisco devices. VTP uses these protocols to manage and propagate VLAN information across a network of switches.
For VLAN Trunking Protocol (VTP) to function correctly, all switches in the VTP domain must be configured with the same VTP domain name. Additionally, at least one switch must be set to VTP server mode to create and propagate VLAN information, while other switches can be configured as clients or transparent modes. Proper trunking must also be established on the links connecting the switches to facilitate the transmission of VTP advertisements.
VLAN
STP stands for Spanning Tree Protocol, which is used to prevent loops in a network by blocking redundant paths. VTP stands for VLAN Trunking Protocol, which is used to manage VLAN configurations across a network by automatically synchronizing VLAN information. Both protocols help in optimizing network performance and ensuring network reliability.
Switches may not be sharing VLAN Trunking Protocol (VTP) messages for several reasons. They might be in different VTP domains, preventing them from exchanging information. Additionally, if one or more switches are set to "client" mode while others are in "transparent" mode, the clients will not share VTP messages with the transparent switches. Lastly, issues such as trunk link misconfigurations or mismatched VTP versions can also hinder message sharing.
Virtual Trunking Protocol (VTP) is a Cisco proprietary protocol used in switched networks to manage VLAN configurations across multiple switches. It allows switches to share VLAN information, ensuring consistency in VLAN configuration throughout the network. VTP reduces the need for manual VLAN configuration on each switch, thereby simplifying network management and reducing the risk of errors. It operates in different modes, including server, client, and transparent, each with specific roles in VLAN information dissemination.

VTP server mode and VTP transparent mode.
The common types of trunking are; VLAN trunking, LTR trunking systems, EDACS trunking systems, Motorola trunking tystems.
The VTP domain cannot be modified.
VTP is Vertical Trading Point
VTP transparent mode allows a switch to forward VTP advertisements but does not participate in the VTP domain. This mode is useful when you want to maintain VLAN information locally without affecting the rest of the VTP domain.
BY using the VTP domain on cisco switch to pass the VLan informetion and any changes that will be happen in vtp server the client switch will get the same informetion from its VTp server switch..
