In this course, we will examine VLANs, VLAN trunks, the layer 3 switch, as well as some common errors one can make while configuring switched networks.

VLANs are a great concept and are widely used throughout the networking industry. The idea of a VLAN is simply that an administrator has the ability to configure a switch such that there are multiple broadcast domains enabled, and inter-broadcast domain communication is not allowed. Effectively, a VLAN is a broadcast domain. In this course, VLAN Operation and Configuration, you will cover all things VLAN related. First, you will examine VLANs, VLAN trunks, the layer 3 switch. Next, you will set up a problematic network, and make errors during configuration. Finally, you will examine both how the network will behave and how to repair broken networks. After completing this course, you will be ready to segment a network with a single switch using VLANs.
