How can you learn LAN switching best practices and resources?

1 Understand the basics

Before you dive into the advanced topics of LAN switching, you need to have a solid grasp of the fundamental concepts and terminology. For example, you should know the difference between layer 2 and layer 3 switching, the functions and features of Ethernet, VLAN, and STP, and the roles and responsibilities of MAC addresses, ARP, and CAM tables. A good way to learn the basics is to read some introductory books or online tutorials, such as LAN Switching and Wireless by Wayne Lewis or LAN Switching Fundamentals by Cisco Press.

3 Follow the standards

LAN switching is not a one-size-fits-all solution, but rather a complex and dynamic process that requires adherence to certain standards and best practices. These standards and best practices are designed to ensure interoperability, security, performance, and scalability of LAN switches and networks. For example, you should follow the IEEE 802.1 standards for VLANs, STP, and QoS, the RFCs for IP addressing and routing, and the Cisco design guides for switch architectures and features.

5 Keep up with the trends

LAN switching is not a static or stagnant field, but rather a dynamic and evolving one that responds to the changing needs and demands of network users and applications. Therefore, you need to keep up with the trends and innovations that affect LAN switching and its future direction. For example, you should be aware of the trends such as cloud computing, software-defined networking, network automation, and network security, and how they impact LAN switching and its design, configuration, and management.
