Introduction to VLAN

Workstations that are connected through the local area network use repeaters or hubs. Through these devices, the information can be sent one after another. Unfortunately if there are two people who are trying to send data simultaneously, there is a big chance that the data would be lost due to information collision. Thankfully, there are now VLANs or Virtual Local Area Networks. Even if you are not on the same area, there will still be a connection within the different workstations. The VLAN Cisco is more efficient compared to the typical LAN. It has more benefits as well including the following:

1. Enhanced network performance - the workstations that requires traffic are the only ones that can receive a broadcast. It prevents the other workstations from getting traffic if it does not need it. As a result, those who need the broadcast will get it faster compared to the performance that they can get when using heavy load routers.

2. It can accommodate more workgroups - even if the workstations are in different floors, the VLAN allows everyone to have an efficient communication though they are connected virtually. Of course this would not work if you are talking about scanners, printers, and other hardware which requires the employees to have physical access.

3. Easier to manage - if you would still opt for the conventional LANs, it would be very hard to administer the network especially if the workstations will be relocated from one place to another. The VLANs no longer require new cables and hub reconfiguration when relocating workstations. At the same time, software administrators would just have to maintain and manage the workgroups virtually.

4. Stricter information security - user groups can be more secured since administrators can prevent others from accessing the broadcast domain as well as the other sensitive information that are received and sent through the network.
