2. Type selection: Select the appropriate switch type based on network needs, such as Ethernet switches, fiber switches, etc. 3. Brand and performance: Choose well-known brands and switches with stable performance to ensure the reliability of network equipment. Pay attention to performance indicators such as processing power and latency. 4. Price and budget: Select a cost-effective switch based on the enterprise's budget. Do not blindly pursue high configurations but choose according to actual needs. Switch Configuration: 1. Initial settings: Perform initial settings for new switches, including setting the management IP address, username, and password. 2. Port configuration: Configure switch ports based on the network topology, including port type, speed, duplex mode, etc. 3. VLAN configuration: Configure Virtual Local Area Networks (VLANs) as needed to achieve network isolation and optimization. 4. Stacking and link aggregation: For large networks, consider using stacking or link aggregation technologies to increase switch port density and bandwidth. 5. Security settings: Configure switch security policies as needed, including access control and port security, to ensure network security. 6. Monitoring and logging: Configure monitoring and logging functions of the switch to facilitate real-time monitoring of network status and troubleshooting for network administrators. Useful Tips and Considerations: 1. Regular inspection: Regularly check the operating status of the switch to ensure its normal operation. 2. Backup and recovery: Regularly backup the switch configuration files for quick recovery in case of problems. 3. Firmware upgrade: Pay attention to firmware updates from switch manufacturers and upgrade them promptly to obtain better performance and security. 4. Rational layout: When installing switches, pay attention to a rational layout for convenient maintenance and management. 5. Training and management: Network administrators should regularly participate in training to improve their skill level to better manage and maintain network equipment.
