I. Selection of High-Quality Switches 1. Brand and Quality: Choose well-known brands and switches with guaranteed quality to effectively reduce failure rates and ensure stable network operation. 2. Port Quantity and Type: Select the appropriate number of ports and port types (such as Gigabit or 10 Gigabit) based on actual needs. Multiple ports and high-speed ports can meet greater traffic demands and improve network speed. 3. Performance Parameters: Pay attention to the forwarding rate, backplane bandwidth, and other performance parameters of the switch, which directly affect the data processing capability of the switch. 4. Scalability and Manageability: Consider whether the switch supports stacking, virtualization, and other functions for future network expansion and management. Additionally, switches with SNMP, Web, and other management functions facilitate daily operation, maintenance, and monitoring. II. Configuration and Optimization of Switches 1. Configure VLANs (Virtual Local Area Networks): Divide the network into different logical subnets by configuring VLANs to improve network security and management efficiency. 2. Optimize Flow Control Strategies: Reasonably configure flow control strategies based on network traffic to avoid network congestion and ensure smooth critical business operations. 3. Regularly Update Firmware: Keep the firmware version of the switch up to date to fix potential security vulnerabilities and performance issues. 4. Rationalize Network Structure Layout: Plan the network topology structure reasonably based on actual needs to avoid issues such as network loops and broadcast storms. 5. Monitoring and Maintenance: Use network management software to monitor switch status in real-time, regularly perform performance testing and maintenance, and ensure stable network operation.
