Why should I take this module?

Welcome to VLANs!

Imagine that you are in charge of a very large conference. There are people from all over who share a common interest and some who also have special expertise. Imagine if each expert who wanted to present their information to a smaller audience had to do that in the same large room with all the other experts and their smaller audiences. Nobody would be able to hear anything. You would have to find separate rooms for all the experts and their smaller audiences. The Virtual LAN (VLAN) does something similar in a network. VLANs are created at Layer 2 to reducing or eliminate broadcast traffic. VLANs are how you break up your network into smaller networks, so that the devices and people within a single VLAN are communicating with each other and not having to manage traffic from other networks. The network administrator can organize VLANs by location, who is using them, the type of device, or whatever category is needed. You know you want to learn how to do this, so don’t wait!
