What is vlan network

It can increase the CPU overhead on each device and reduce the overall network security. Hosts of VLANs will not even be aware that the communication took place. This is shown in the below picture:. A LAN is a group of computer and peripheral devices which are connected in a limited area such as school, laboratory, home, and office building. It is a widely useful network for sharing resources like files, printers, games, and other applications. In the below example, there are 6 hosts on 6 switches having different VLANs.

You need 6 ports to connect switches together. It means, if you have 24 various VLANs, you will have only 24 hosts on 45 port switches. Port-based VLANs groups virtual local area network by port.

Devices that are connected to this port will belong to the same broadcast domain that is because all other ports are configured with a similar VLAN number. The challenge of this type of network is to know which ports are appropriate to each VLAN. You can determine it by checking the configuration information. Was this article helpful?

End nodes can communicate with each other without a router. Routers connect LANs, routing the traffic to each appropriate port. A virtual LAN VLAN is a local area network that maps devices on a basis other than geographic location, for example, by department, type of user, or primary application.

A VLAN is a group of network devices computers, servers, and other resources that behave as if they are connected to a single network segment, even though they might not be. For example, the marketing personnel might be located throughout a building, yet if they are all assigned to a single VLAN, they can share resources and bandwidth as if they are connected to the same segment.
