VLAN INTRODUCTION CONCEPT PPT. VIRTUAL LAN

Introduction of VLAN

1. Introduction to Virtual LAN (VLAN) An overview of VLAN technology and its applications.

2. What is VLAN? VLAN (Virtual Local Area Network) is a technology that allows network segmentation. Benefits of VLANs: - Enhanced security - Improved network performance - Simplified management

3. Why Use VLANs? Network Segmentation: - Divides large networks into smaller segments Enhanced Security: - Isolates sensitive data Improved Performance: - Reduces broadcast traffic

4. How VLAN Works VLAN tagging and frame identification: - Tags are added to Ethernet frames - Switches identify VLAN membership using tags

5. Types of VLANs 1. Data VLAN 2. Voice VLAN 3. Management VLAN 4. Native VLAN

6. VLAN Configuration Access Port: - Connects end devices to VLAN Trunk Port: - Carries multiple VLANs between switches

7. VLAN Trunking Protocol (VTP) VTP simplifies VLAN management across switches by distributing VLAN information. VTP Domain: A group of switches sharing VLAN information.

8. Advantages and Disadvantages Advantages: - Flexibility - Improved security - Reduced congestion Disadvantages: - Complexity - Misconfiguration risks

9. Real-World Applications Corporate networks Educational institutions Data centers

10. Conclusion VLANs improve network management and performance while enhancing security.
