VLAN (Virtual Local Area Network) is a logical local area network (or LAN) that extends beyond a single traditional LAN to a group of LAN segments, given specific configurations. Since a VLAN is a logical entity, its creation and configuration is done completely in software.here are only two types of VLAN possible today, cell-based VLANs and frame-based VLANs. 1  Cell-based VLANs are used in ATM switched networks with LAN Emulation (or LANE). 2  Frame-based VLANs are used in Ethernet networks with frame tagging.
VLANs are data link layer (OSI layer 2) constructs, analogous to IP subnets, which are network layer (OSI layer 3) constructs. In an environment employing VLANs, a one-to-one relationship often exists between VLANs and IP subnets, although it is possible to have multiple subnets on one VLAN.nder IEEE 802.1Q, the maximum number of VLANs on a given Ethernet network is 4,094 (the 4,096 provided for by the 12-bit VID field minus reserved values 0x000 and 0xFFF). This does not impose the same limit on the number of IP subnets in such a network, since a single VLAN can contain multiple IP subnets.
