Information About VLANs
Understanding VLANs
A VLAN is a group of end stations in a switched network that is logically segmented by function or application,
without regard 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 switch port can belong to a VLAN, and unicast, broadcast, and multicast packets are forwarded and
flooded only to end stations in that VLAN. Each VLAN is considered as a logical network, and packets
destined for stations that do not belong to the VLAN must be forwarded through a router. The following figure
shows VLANs as logical networks. The stations in the engineering department are assigned to one VLAN,
