What are the most in-demand LAN switching skills?

由人工智能和领英社区提供技术支持

LAN switching is a core skill for computer networking professionals who work with local area networks (LANs) and connect devices within a single site or building. LAN switching involves creating, configuring, and managing switches, which are devices that forward data packets between network segments. Switches can improve network performance, security, and scalability by reducing collisions, filtering traffic, and creating virtual LANs (VLANs). In this article, you will learn about the most in-demand LAN switching skills that can help you advance your career in computer networking.

1 Basic LAN Switching Concepts

Before you can become proficient in advanced LAN switching skills, it's essential to understand the basics of LAN switching. This includes knowledge of switching modes such as store-and-forward, cut-through, and fragment-free, as well as the functions of MAC address learning, forwarding, and filtering. It's also important to understand the types of switch ports--access, trunk, and hybrid--and port security with MAC address filtering, sticky MAC, and port security violation modes. Additionally, you should be familiar with VLANs and their configuration, as well as VTP modes, domains, and pruning. Finally, you should understand the purpose and operation of STP and its variants. To be successful in LAN switching, you need to be able to explain these concepts and how they affect performance and design. You must also be able to use basic commands to configure and troubleshoot switches and VLANs.
