VLAN (EN)

Definition

VLAN (Virtual Local Area Network) is a technology that enables the logical division of physical network segments into multiple separate networks. By implementing VLANs, you can isolate different departments or functional areas without providing additional physical infrastructure. VLANs enhance network security by restricting traffic between different segments and reduce the size of broadcast domains, which can improve network performance. In this module, you will learn the configuration and management of VLANs for your network segmentation.
