Description of What Is Network Switching? Learn Network Engineer Skills
This lab-based switching course walks you through the real-world configuration of Layer 2 and Layer 3 switches. Youβll start with foundational conceptsβMAC addresses, forwarding decisions, and how unmanaged switches differ from managed switches. Then you'll build switching topologies and configure switch ports, VLANs, EtherChannel, and the STP election process.
Youβll work with data center switches, simulate enterprise networks, and explore Spine & Leaf architectures using OSPF and eBGP. Troubleshooting commands like err-disable, port mirroring, and SPAN will help you monitor traffic and ensure network security. From device MAC addresses to local devices on the same switch, youβll practice with the tools that real network administrators use.
- Forward data packets using destination MAC addresses
- Configure managed switches through CLI and web interfaces
- Secure switch ports and prevent unauthorized access
- Build reliable local networks with VLANs and access control
- Monitor network traffic using SPAN and port mirroring
- Use scripting languages for repetitive tasks in switch management
- Practice hands-on with cloud networking and IoT devices
By the end of the course, you'll be ready to deploy and troubleshoot complex switching scenarios in both local and enterprise environments. You'll confidently manage switch ports, configure VLANs, and optimize traffic pathsβskills that many organizations now expect alongside familiarity with the OSI model, scripting languages, and integrating specific devices or other networked systems, even as automation and machine learning shape the future of switching.

Sergei O.
This switching course gave me the confidence to configure managed switches and troubleshoot complex networks. I finally understand how data packets move between devices connected on a single switch and how to use the MAC address table for efficient data transmission. The labs on VLANs, switch port security, and enterprise switches were incredibly useful.

Thomas D.
Great hands-on training that clarified what is network switching and how the data link layer works. The focus on MAC addresses, port mirroring, and forwarding logic really helped me monitor traffic across multiple devices. I also appreciated the real-world examples of managing ethernet ports, access control, and communication between wireless access points and user devices.

Aisha R.
This course broke down the switching process and helped me understand how to forward data efficiently to the destination device. I practiced configuring Spine & Leaf topologies, using access points, and implementing security on network equipment. Itβs ideal for anyone managing network components in large-scale environments or learning how to work with cloud networking setups.
