4.4.7.2 802.1Q VLAN Concept
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
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.
This allows VLAN to accommodate network moves, changes and additions with the greatest
flexibility.
802.1Q VLAN Concept
Port-Based VLAN is simple to implement and use, but it cannot be deployed cross switches VLAN.
The 802.1Q protocol was developed in order to provide the solution to this problem. By tagging
