4.2 Configuring VLAN
4.2.1 VLAN Definition
Logically, one LAN (Local Area Network) can be divided into many subsets. Each subset has its own
broadcast area: virtual LAN (VLAN). A VLAN is divided from a LAN on a logical basis rather than on a
physical basis, to realize the isolated broadcast area in the VLAN.
4.2.2 VLAN Function
● Enhance the network performance. The broadcast packets are in the VLAN, which can effectively
control the network broadcast storm, reduce network bandwidth and enhance network
processing ability.
● Enhance the network security. The switches in different VLANs cannot access each other, and the
hosts in different VLAN cannot communicate with each other. They need a router or the
three-layer switch to forward the message.
● Simplify the network management. The host of the same virtual working group is not limited in
one physical area, which can simplify the network management and facilitate to establish
working groups for users in different areas.
4.2.3 Port-based VLAN
The port types include Access, Trunk and Hybrid.
● Access: The port belongs to one VLAN, and is used to connect to the computer port.
● Trunk: The port allows multiple VLANs to pass, to receive and send messages of multiple VLANs,
and is used to connect between the switches.
● Hybrid: The port allows multiple VLANs to pass, to receive and send messages of multiple VLANs,
and is used to connect between the switches, and connect the computer.
