We consider this work, if the use of a simulation telematic tool, specific and previously chosen, enhances academic studies efficiently. In addition the use of these tools allows us to step beyond theory, manually configure the devices as well as overview how to manage telematic devices. To achieve the objective of this work, we propose studying diferent mechanisms of layer 2 in a simulated environment. The mechanisms studied are: Spanning-Tree, VLANs and Link Aggregation. Each mecanisn consists of a chapter. First a brief theoretical introduction to proposes a network topology. Once we have created the network at simulator, we apply a basic settings to devices. The tests allow us verifies the correct operation of the mechanism. If the results are satisfactory and the simulator allows us, we apply an advanced configuration of this mechanisms to different devices. To end each chapter we will present a comparison between the obtained results and the expected results. Also we present all the problems and limitations we have encountered during the study. To conclude the work, will assess whether the objective has been achieved and the use of this simulation tool can strengthen the theoretical knowledge
