• Enhanced Network Security: Features include 802.1Q VLAN, IP-MAC-Port binding, Access Control List (ACL), Port Security, DoS defend, Storm control, DHCP Snooping, and 802.1X radius authentication.
• L2+ Features: Static Routing helps route internal traffic for more efficient use of network resources.
• Standalone Management: Web-based GUI, CLI (Console Port, Telnet, SSH), SNMP, RMON, and Dual Image provide powerful management capabilities.

This diagram illustrates how VLANs can be used to segment your network, for example, separating surveillance, office, and guest networks for improved security and performance.

7. Maintenance

To ensure optimal performance and longevity of your TL-SG3428 switch:

• Firmware Updates: Regularly check the TP-Link official website for the latest firmware updates. Keeping the firmware up-to-date ensures access to new features, performance improvements, and security patches.
• Cleaning: Keep the switch clean and free from dust. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or aerosol sprays.
• Ventilation: Ensure that the ventilation holes are not blocked to prevent overheating.
• Power Cycle: If the switch experiences unusual behavior, try power cycling it by disconnecting and reconnecting the power cord.

8. Troubleshooting

This section addresses common issues you might encounter with your TL-SG3428 switch.

• No Power: Ensure the power cord is securely connected to the switch and a power outlet. Verify the power outlet is functional.
• No Link/Activity on a Port: Check the Ethernet cable connection at both ends. Ensure the connected device is powered on and functioning correctly. Verify the port LED is lit.
• Cannot Access Web Management Interface: Ensure your computer's IP address is in the same subnet as the switch. Verify the switch's IP address. Clear your browser's cache or try a different browser.
• Omada Controller Cannot Adopt the Switch: Ensure your Omada controller's firmware is up to date. The switch might need a firmware update to be compatible with the controller. Ensure DHCP is enabled on the VLAN where the switch is located for proper adoption, then you can assign a static IP if desired.
• Slow Network Performance: Check for network loops, excessive broadcast traffic, or faulty cables. Utilize QoS settings to prioritize critical traffic.
• USB Console Issues: Some older hardware versions might require specific drivers for the USB console port, which may not be automatically installed. Consider using the RJ45 serial console port with a compatible USB-to-serial adapter if issues persist.
