User Manual
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
