3. Routing function: Some advanced network switches also have routing functions, which can perform routing selection and forwarding between different networks. 4. Access control: Network switches can implement access control for the network through strategies such as setting access control lists (ACLs), ensuring that only data packets that meet the conditions can pass through. 5. Network monitoring and management: Through network management software or command line interfaces, administrators can configure, monitor, and manage network switches to ensure network stability and security. III. Characteristics of Network Switches 1. High performance: Network switches adopt high-speed processors and caching technology to process a large number of data packets, meeting the needs of high concurrency and high load application scenarios. 2. Flexibility: Network switches support multiple protocols and interface types, which can be flexibly applied to various network environments and business needs. 3. Scalability: Many network switches support modular design, which allows users to easily expand and upgrade according to their needs. 4. Security: Network switches have a variety of security features, such as port isolation and access control, which can effectively improve network security. 5. Usability: Network switches provide a wealth of management tools and interfaces to facilitate user configuration and management. 综上所述，网络交换机作为多功能的网络中心核心设备，具有丰富的功能和特性，为企业的信息化建设和网络管理提供了强有力的支持。在未来的发展中，随着技术的不断进步和应用场景的不断拓展，网络交换机将会发挥更加重要的作用。
