Analysis of Virtual Trunk Protocol (VTP)This section introduces and analyses the Virtual Trunk Protocol (VTP), used to automatically update all switches in a VLAN network, with all new VLAN information, ensuring all switches are up to date and aware of the VLAN topology.

We start with the introduction of VTP where we analyse the different modes the VTP protocol operates on. Using detailed diagrams, we provide enough information to make the learning process easy and enjoyable.

Next we take a in-depth look at the VTP protocol by analysing its headers and available fields.  We lastly analyse VTP Pruning, explaining what exactly it is and how it can help conserve bandwidth and increase our network security.

All articles use our popular colourful diagrams that help dramatically make the learning process easy and clear.
