VLAN Reduces the Size of Broadcast Domains.
By confining the broadcast domains, end-stations on a VLAN are prevented from listening to or receiving broadcasts not intended for them. Moreover, if a router is not connected between the VLANs, the end-stations of a VLAN cannot communicate with the end-stations of the other VLANs. Confinement of broadcast domains on a network significantly reduces traffic.
VLAN Can Enhance Network Security.
Virtual boundaries created by a VLAN can only be crossed by routers. Therefore, access to the VLAN can be restricted using standard router-based security measures. In addition, VLANS can enhance network security through packet filtering. Network administrators control each port and any resources they allow to be used, separating groups with sensitive data from the rest of the network and reducing the chance of confidential information leaking.
VLANs Are Easy to Manage.
VLAN makes network management easier because users with similar network requirements share the same VLAN. When a new switch is provided, you can quickly add or change network nodes on the web management page of the switch. All policies and procedures configured for a specific VLAN are implemented when ports are allocated. IT staff can also easily identify the functionality of a VLAN by giving It an appropriate name.
VLAN Makes It Easy to Manage Other Devices.
VLANs simplify project and application management and aggregate users and network devices to support business or geographic needs. Having separate capabilities makes it easier to manage projects or use dedicated applications, and devices can be logically grouped based on functionality rather than location.
