26-Nov-2023A VLAN, or Virtual Local Area Network, is a network segmentation technique that allows network administrators to logically partition a single physical network into multiple isolated virtual networks. VLANs are created to enhance network performance, security, and manageability by grouping devices based on logical criteria rather than their physical location.
How VLANs Work:
Logical Grouping:
Tagging Frames:
Switch Configuration:
Inter-VLAN Routing:
Benefits of Using VLANs to Segment a Network:
Enhanced Security:
Improved Performance:
Simplified Network Management:
Flexibility and Scalability:
Broadcast Domain Isolation:
Quality of Service (QoS):
Guest Network Segmentation:
Compliance and Regulatory Requirements:
Resource Optimization:
In summary, VLANs provide a powerful means to segment and organize network traffic logically, offering benefits such as improved security, performance, and manageability. They are a fundamental tool in modern network design, especially in environments where flexibility, scalability, and security are paramount.
