Detailed Explanation of Enterprise-Level Switch Security Features: 1. Access Control: Enterprise-level switches support policy-based access control (ACL), which enables fine-grained management of network traffic. By setting up access control lists (ACLs), administrators can define which IP addresses, MAC addresses, or applications are allowed or denied to communicate through the switch. Additionally, access control can be based on conditions such as time and ports, ensuring that only qualified users or devices can access network resources. 2. Attack Defense: Enterprise-level switches have firewall functions that can effectively resist network attacks. These attacks include common network attack methods such as ARP spoofing and IP flooding. The switches monitor and analyze network traffic, filter out and block abnormal traffic, protecting the enterprise network from attacks. Furthermore, some advanced enterprise-level switches also have intrusion detection and prevention (IDS/IPS) functions, which can detect and defend against potential network threats in a timely manner. 3. Data Encryption: Data encryption is one of the important means to ensure network security. Enterprise-level switches support a variety of encryption protocols such as IPSec and SSL, which can encrypt data transmission to protect it. By using these encryption protocols, it can ensure that data cannot be intercept
