Episode 28: VLAN Configuration and Trunking Essentials
Building on the previous episode, this segment walks you through how VLANs are configured on switches and how trunking enables them to work across multiple devices. You’ll learn how to assign ports to VLANs, configure trunk interfaces, and verify settings using show commands. We also explain native VLANs and how misconfigurations can lead to traffic loss or security risks.
We highlight the difference between access and trunk ports, describe how to troubleshoot VLAN mismatches, and explain the impact of VLAN pruning. By the end of this episode, you’ll be able to confidently configure and verify VLANs across switches and avoid common mistakes that cause connectivity problems.
