Now we apply VLAN technology to configure the system shown as the figure

above. We can partition the users into the different logical networks which have

their own broadcast domain. The traffic will not disturb among these logical

networks. The users 1x (x denotes a ~ d) are members of VLAN 1. Any traffic within

VLAN 1 does not flow to VLAN 2 and others. This helps us configure the network

easily according to the criteria needed, for example, financial, accounting, R&D and

whatever you think it necessary. You can also easily move a user to a different

location or join a new user somewhere in the building to VLAN. Without VLAN, it is

very hard to do. Basically, VLAN can afford offering at least 3 benefits: move and

change users, reduce broadcast traffic and increase performance, Security.

Besides, VLAN can highly reduce the traffic congestion and increase total

performance because there are no more too many users in the same broadcast

domain.

There are two types of VLAN applied. Most popular is port-based VLAN, tag-

based VLAN

 Port-based VLAN

Some physical ports are configured as members of a VLAN. All stations

attached on these ports can communicate with each other.

 Tag-based VLAN

It identifies the membership by VLAN ID, no matter where the packet

comes from. It is also referred to as 802.1Q VLAN.
