Virtual local area network (VLAN)
Implemented on network switches in a LAN as a way of logically grouping users and resources in a broadcast domain. Often, such VLANs correlate to department functions (such as Accounting, Sales, and Research & Development) and/ or IP subnets. VLANs provide scalability, segmentation, and (some) security at Layer 2 and can also work to limit the size of your Ethernet broadcast domains. VLANs are implemented by using Institute of Electrical and Electronics Engineers (IEEE) 802.1q tagging to tag Ethernet frames with VLAN information. Note: the IEEE is an international organization that defines many standards, including numerous 802 networking standards.
