What is VLAN?
A VLAN is a logical grouping of network resources connected to administratively defined ports on a switch. VLANs break a large broadcast domain into smaller broadcast domains. Each VLAN creates a separate broadcast domain.
Basic concepts and fundamentals of VLANs
A LAN is a group of devices connected to a single Ethernet network. A broadcast message is a message that reaches all devices in the network. Devices use broadcast messages to perform many essential tasks. The more devices you add to a network, the more broadcast messages it will have. Broadcast messages reduce network performance.
To improve network performance, administrators break the LAN network into smaller LANs. When you break a large LAN into smaller LANs, you create VLANs. VLANs are smaller LANs. VLANs create a boundary for broadcast messages. A broadcast message generated in a VLAN reaches all devices inside the VLAN. It does not go outside the VLAN. If two devices belong to different VLANs, they do not exchange broadcast messages.
How VLANs work
A switch does not understand broadcast messages. When it receives a broadcast message on one of its ports, it forwards that message from all other ports. Let us take an example. Suppose an 8-port switch receives a broadcast message on port-1. It forwards the message from ports 2 to 8.
A VLAN is a switch-only feature. It allows us to define ports that share broadcast messages. If two switch ports belong to different VLANs, they do not share broadcast messages. If two ports belong to the same VLAN, they share broadcast messages.
Key points: -
VLANs are a switch-only feature. It works only on manageable Ethernet switches.
VLANs are used to create boundaries for broadcast messages.
VLANs do not share broadcast messages.
Devices in different VLANs cannot communicate directly. They can communicate through a router.
You can create and use the same VLAN on multiple routers. This feature allows you to arrange devices logically.
All switches have a default VLAN, called VLAN1.
By default, all switch ports belong to VLAN1.
