2.6.15 VLAN command mode
A Virtual Local Area Network (VLAN) is a network topology configured according to a logical
scheme rather than the physical layout. VLAN can be used to combine any collections of
LAN segments into a group that appears as a single LAN. VLAN also logically segments the
network into different broadcast domains. All broadcast, multicast, and unknown packets
entering the Switch on a particular VLAN will only be forwarded to the stations or ports that
are members of that VLAN.
VLAN can enhance performance by conserving bandwidth and improve security by limiting
traffic to specific domains. A VLAN is a collection of end nodes grouped by logics instead of
physical locations. End nodes that frequently communicate with each other are assigned to
the same VLAN, no matter where they are physically located on the network. Another
benefit of VLAN is that you can change the network topology without physically moving
stations or changing cable connect
ions. Stations can be „moved‟ to another VLAN and thus
communicate with its members and share its resources, simply by changing the port VLAN
