2.8.4 VLAN Configuration
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 collection of
LAN segments into a group that appears as a single LAN. VLAN also logically segment 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 logic instead of
physical location. End nodes that frequently communicate with each other are assigned to
the same VLAN, regardless of where they are physically on the network. Another benefit of
VLAN is that you can change the network topology without physically moving stations or
changing cable connections. Stations can be ‘moved’ to another VLAN and thus
communicate with its members and share its resources, simply by changing the port VLAN
settings from one VLAN to another VLAN. This allows VLAN to accommodate network
moves, changes and additions with the utmost flexibility.
