Many benefits of configuring VLAN as listed below:
• Performance Enhancements: It reduces heavy load on the network by permitting operations at lower latencies by using VLAN to create broadcast domains. VLAN creates smaller domains which reduces overhead and also the limits the use of resources.
• Ease of Administration: VLAN can help in reducing the cost of network additions and relocation. Virtual workgroups can be created for multiple users and complete workstations can be shifted without implementing any new hardware from one station to another.
• Information Security: VLAN can be used for implementing different network access options like restricting access of users. It can also be used to prevent other users present outside the broadcast domain for securing different workgroups and sensitive information.
• Flexibility and Scalability: VLAN is used to assign a broadcast domain to each user individually according to the port number of the system of the user and if a user wants to change the domain then it can be changed easily by reconfiguring the port assigned to the user. VLANs are also not bounded to a single switch for example, in an enterprise if there are different workgroups on different floors connected to multiple switches but on a same VLAN can also be easily scaled by WAN link.
