Virtual LANs can be used to divide users into several groups and only allow users to use the network resources they need. VLANs are divided based on principles such as port VLANs, MAC addresses, and routing access lists, limiting unauthorized access between different VLANs.

Moreover, the IP/MAC address binding function can be set to restrict users' unauthorized network access, thereby improving the overall performance and security of the network switch. Moreover, by creating VLANs, broadcasts are isolated, the broadcast range is reduced, and the generation of broadcast storms can be controlled.

For networks using VLAN technology, a VLAN can divide network users from different geographical locations into a logical network segment based on departmental functions, object groups, or applications.

The linkage between the enterprise switch and the IDS system is a very practical and ideal solution without increasing investment costs.

Due to the fact that both viruses and IDS rely on network platforms for attacks, using IDS as a monitoring system in conjunction with switches can cut off the transmission path of viruses and achieve unexpected security effects on the network platform.

Specifically, the linkage between enterprise network switches and IDS systems refers to the process in which switches report various data flow information to security devices during operation, and IDS can detect based on the reported information and data flow content.

When network security events are discovered, targeted actions are taken and these actions in response to security events are sent to the switch, which implements precise port disconnection operations. This technology has been recognized by the vast majority of users, but it has not yet been widely applied in practice.
