A VLAN is a group of end stations with a common set of requirements, independent of their physical location. A VLAN has the same attributes as a physical LAN, except that it lets you group end stations even when they are not physically located on the same LAN segment. A VLAN also lets you group ports on a switch so that you can limit unicast, multicast, and broadcast traffic flooding. Understanding how VLANs operate and what the associated protocols are is important for configuring, verifying, and troubleshooting VLANs on Cisco switches, and in this course you will learn VLAN operations and their associated protocols. You will also learn how and when to implement and verify VLANs, trunking, and VTP, and then implement them on the network. Finally, you will be able to describe VLANs, trunking, and how to implement a redundant topology. This course is one of a series in the Skillsoft learning path that covers the objectives for Cisco exam 640-911: Introducing Cisco Data Center Networking.

Target Audience
Data center network engineers and learners embarking on a network administration or engineering career who wish to expand their skills in data center networks.
