VTP stands for VLAN Trunking Protocol and is used to manage VLAN configurations across a network. Here are the three things a network administrator should tell a new technician about VTP configuration:
A switch in the VTP client mode cannot update its local VLAN database. When a switch is configured in VTP client mode, it cannot create, modify or delete VLANs. The only way for VLANs to be created, modified or deleted is through a VTP server. The switch will receive VTP updates from the server and synchronize its VLAN database with the server's VLAN database.
A trunk link must be configured between the switches to forward VTP updates. VTP updates are sent as multicast frames over the network, and they need to be able to pass through all switches in the VTP domain. To achieve this, a trunk link must be configured between the switches, so that VLAN information can be carried between them.
A switch in the VTP server mode only updates switches in the VTP client mode that have a higher VTP revision number. When a switch is configured as a VTP server, it can create, modify and delete VLANs, and these changes will be propagated to all other switches in the same VTP domain. However, for the changes to be applied to a switch in VTP client mode, the client's VTP revision number must be lower than the server's revision number. If the client's revision number is equal to or higher than the server's, the server will not send VTP updates to that client.
In summary, VTP is a protocol used to manage VLAN configurations across a network. A switch in VTP client mode cannot create, modify or delete VLANs, and VTP updates are sent as multicast frames over a trunk link. A switch in VTP server mode can create, modify and delete VLANs, but its updates will only be applied to switches in VTP client mode that have a lower VTP revision number.
