Local Area Networks (LAN) White Papers

Network Warrior: VLANs

Overview Virtual LANs, or VLANs, are virtual separations within a switch that provide distinct logical LANs that each behaves as if they were configured on a separate physical switch. Before the introduction of VLANs, one switch could serve only one LAN. VLANs enabled a single switch to serve multiple LANs. Assuming no vulnerabilities exist in the switch's operating system, there is no way for a frame that originates on one VLAN to make its way to another.
