What is VLAN?****
A Virtual Local Area Network (VLAN) is an advanced network technology that enables the segmentation of a physical network into smaller, isolated sub - networks. Even when devices are physically connected to the same switch or router, each VLAN operates as an independent and distinct network. This isolation creates a more secure and efficient networking environment. For example, in a network setup where a DR6018 AP with an IP address of 192.168.1.3 and a DR6018 STA with an IP of 192.168.1.2 are interconnected wirelessly within Vlan 100, they form a dedicated virtual local - area network segment. Alongside, on the wired side, SW1 and SW2 act as key switching devices. Port 7 on SW1 is set as untagged, while port 8 is tagged for Vlan 100, and the same configuration exists on SW2. This tagging system ensures proper handling and isolation of Vlan 100 traffic as it moves between the switches. PC1, with an IP of 192.168.1.96, is connected to port 7 of SW1, and PC2, having an IP of 192.168.1.112, is linked to port 7 of SW2. Such a setup showcases how VLANs facilitate effective communication within the Vlan 100 domain while maintaining the security and integrity provided by the VLAN technology.
Why VLAN?****
VLANs offer multiple significant advantages for contemporary networking:
· Enhanced Security: By separating different areas of your network, VLANs safeguard sensitive data from being accessed by unauthorized devices, significantly bolstering overall security.
· Superior Traffic Management: VLANs limit broadcast traffic to specific segments, reducing network congestion and substantially improving network performance.
· Streamlined Network Management: Network administrators can effortlessly group devices according to their function, department, or other criteria, all without the need to modify physical connections.
· Cost - effectiveness: VLANs minimize the necessity for costly hardware upgrades. They enable the logical segmentation of the network without the need for additional physical infrastructure.
· Increased Flexibility: Devices can be seamlessly moved between VLANs without the hassle of physical rewiring. This provides greater flexibility as your network expands and evolves.
