In this chapter, we explained how switches allow us to segment a network and reduce collision domains. We discussed the various characteristics of switches and highlighted the difference between managed and unmanaged devices. We also talked about cabling between endpoints and switches via patch panels. In addition to this, we walked through the process of frame forwarding and mechanisms to prevent broadcast storms occurring. We finished this chapter by discussing various security processes we can employ on a switch.
This chapter taught you how to identify collision domains on a network. By combining this with the knowledge you have of various different topologies and their access methods, you will be able to implement an efficient network with ease. You also learned how a switch populates its MAC/CAM table during the frame forwarding process. An understanding of this will...
