The following are the advantages of VLAN:
Improve the network performance. This technology confines the broadcast packages in
a local area network within a single VLAN to save the network bandwidth and improve
the capacity.
Reduce the investment on devices. VLAN technology realizes the achievable control of
network management cost, instead of increase of that in the traditional broadcast storm
isolation using router.
Simplify network management. The VLAN establishes virtual work groups across the
geographical network. As long as locating geographically in the range of the virtual local
area network, the user is capable of accessing to the network without altering the
configuration.
