Virtual Lans - Delta DVS-328 series User Manual

3.4 Virtual LANs

Virtual LAN (VLAN) is a logical group network. VLANs electronically separate interfaces on the same switch
into different broadcast domains so that broadcast packets are not sent to all the interfaces on a single switch.
VLAN allows the switch manager to isolate network traffic so that only members of the VLAN can receive traffic
from the same VLAN members. VLAN also allows a user to access the network from a different place or switch.
So VLAN provide security and flexibility.
For example: Configure department A, B, C to VLAN 1, 2, 3. Users can only access the resource which belongs
to their department, so the resource in their department can be protected. And they can access the resource in
a different floor, even though in a different place. So they do not need to stay in a fixed place to access the
resource which belongs to their department.
IMPORTANT:
Make sure that you save the configuration in the Save Configuration
page after you have applied the configuration changes. (Save
ConfigSave Configuration) If you do not save the configuration,
then the configuration will be cleared after the switch is rebooted.
