Offers security by completely isolating from each other the different broadcast
Network administrators can easily "fine tune" the network.
ou can group users according to some shared characteristic, such as a common business
nction or a common protocol. A single switch may have several independent VLANs
ithin it. On the following page is an example in which an R&D, Manufacturing and
dministration group can be partitioned into two different VLAN groups. Even
members in different groups cannot talk directly, but they still share the same server, such
as an MRP server, printer server in the Administration group, etc.
Benefits of VLANs:
z Grouping users into logical networks for performance enhancement.
z Provide effective broadcast containment between segmented ports, which prevents
flooding of a network.
z
domains connected on separate segmented ports.
z Preserving current investment in equipment and cabling.
z Providing an easy, flexible, and economic way to modify logical groups when
needed.
z
z Keeping network structure from the physical topology of the cabling.
z Making large networks more manageable.
