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.
3.5.1
VLAN Membership
VLAN Membership is used to define VLAN groups and the VLAN information will be stored in the VLAN membership table.
A Delta Layer 3 switch supports up to 64 VLANs. VLAN 1 is the default VLAN, and all interfaces are untagged members by
the default setting.
Note:
If you need to access the switch via the port, we suggest that you make sure that the port you use is the
untagged port of VLAN 1 (the default VLAN).
