thumb|The general concept of virtual LANs.
A virtual local area network (VLAN) is a local area network broadcast domain that is partitioned and isolated in a virtual network at the data link layer (OSI layer 2). A VLAN behaves like a virtual network switch or network link that can share the same physical structure with other VLANs while staying logically separate from them.
