Understanding How VLANs Work
A VLAN is a group of end stations with a common set of requirements, independent of their physical
location. A VLAN has the same attributes as a physical LAN but allows you to group end stations even
if they are not located physically on the same LAN segment.
VLANs allow you to group ports on a switch to limit unicast, multicast, and broadcast traffic flooding.
Flooded traffic originating from a particular VLAN is only flooded out ports belonging to that VLAN.
