What is VLAN?

Rating:

Virtual local area network (VLAN) is a virtual subnet, which is created by switches and supported routers that are VLAN enabled. VLAN is created by tagging the data frames that a switch receives from hosts. Each port on the switch behaves in the same way as an IP subnet and might require routing to communicate with hosts on other VLANs. VLANs can be used to isolate hosts and segments and to control broadcast traffic.
