Benefits of VLANs
zGrouping users into logical networks for performance enhancement.
zProvides effective broadcasts containment between Segmented Ports, which prevents flooding of a network.
zOffers security by completely isolating from each other the different Broadcast Domains connected on separate Segmented Ports.
zPreserving current investment in equipment and cabling.
zProviding an easy, flexible, economic way to modify logical groups when needed.
zNetwork administrators can easily "fine tune" the network.
zKeeping network structure from the physical topology of the cabling.
zMaking large networks more manageable.
You can group users according to some shared characteristic, such as a common business function or a common protocol. A single switch may have several independent VLANs within it. Below is a example that R&D, Manufacturing and Administration group can be partitioned into two different VLAN group, even members in different group can’t talk directly, but they still share the same server, such as MRP server, printer server in Adminstration group…etc.
