Information About VLANs

Understanding VLANs

A VLAN is a group of end stations in a switched network that is logically segmented by function, project
team, or application, without the limitation to the physical locations of the users. VLANs have the same
attributes as physical LANs, but you can group end stations even if they are not physically located on the
same LAN segment.
Any port can belong to a VLAN; all unicast, broadcast, and multicast packets are forwarded and flooded only
to end stations in that VLAN. Each VLAN is considered a logical network. If a packet destination address
does not belong to the VLAN, it must be forwarded through a router.
