About VLANs
A VLAN is a group of devices on one or more LANs that are configured to communicate as if they were
attached to the same wire, when in fact they are located on a number of different LAN segments. Because
VLANs are based on logical instead of physical connections, they are extremely flexible.
Note VTP version 3 updates do not pass through promiscuous trunk ports.
