Different Approaches To VLANs

VLAN Trunking Protocol (VTP): VTP enables automated VLAN configuration dissemination across numerous network switches. VLAN Routing: VLAN routing is the process of routing traffic between VLANs utilising Layer 3 switches or routers. VLAN Security: By separating critical resources and instituting access control, VLANs may be utilised to improve network security....

Applications of VLAN

Network Segmentation: VLANs offer network segmentation, allowing distinct departments or projects to have their own isolated network environments. Broadcast Control: VLANs limit the scope of broadcast traffic, which reduces network congestion and improves overall performance....

Advantages of VLAN

Security: VLANs can segregate critical data, restricting unauthorised access and decreasing the attack surface. Improved Network Performance: VLAN segmentation minimises broadcast traffic, which improves network performance. Scalability: VLANs provide flexible network growth without requiring physical reconfiguration....

Disadvantages of VLAN

Complexity: Configuring and administering VLANs may be difficult, necessitating networking knowledge and careful planning. Administrative Overhead Increased: VLANs may need greater administrative work for maintenance, monitoring, and troubleshooting. Limited Broadcast Domain:A tiny broadcast domain might get saturated if VLANs are not appropriately constructed, reducing network performance....

Conclusion

Creating and removing VLANs on a Cisco Catalyst Switch is a critical network management operation. You can efficiently manage VLANs to optimise network performance and security by following the step-by-step guidance and learning the fundamentals, subtopics, applications, benefits, and drawbacks....
