In this video we delve into the concept of VLANs or Virtual Local Area Networks and their importance in IT. We introduce you to traditional VLANs, showing you how to make logical groupings on a switch and assign specific ports to certain VLANs for efficient network management. We also go in-depth into the creation and configuration of VLANs on a Cisco switch using Cisco's Packet Tracer, a network simulation software. Further, we share best practices in switchport security including shutting down unused ports, and discuss VLANs in terms of the OSI model. The tutorial video ends with a practical demonstration of setting up VLANs and explaining how segmentation is achieved through VLANs. We also cover the following: - What is a VLAN? - Why are VLANs used? - How are VLANs used? - Logical Segmentation - Secure Enclaves - How a switch tags traffic with a VLAN ID - Configuring VLANs on a Cisco switch =========================================================== Full course playlist here: https://youtube.com/playlist?list=PLwwAN0Pru-1-Kj6thocL8lBDf_f2hN6Eb&si=o4vZ9OhvMTAjCvJg Please know that this course is not designed to help you pass a test but to help you build applicable skills.
