Virtual LANs enable to perform this task in a very smart way. Also when de-
partments or companies change at a later time inside of the building, the net-
work structure can be easily adjusted.
All network users in this example use the central Ethernet, which is, like the
connected devices, supervised by a service provider. Company A has three
departments on two floors. The sales department can communicate with the
administration department via VLAN ID 3, the accounts department with the
administration via VLAN ID 5. The networks of accounts department and
sales do not see each other. Company B is also shielded by VLAN ID 11
against all other networks, only the service provider can access all devices
for maintenance purposes.
