Week 07 Posting - CDP is still confusing.

From what I can understand, the book shows you the commands, how to bring up the CDP information, and the different information you can bring up. The only thing I get confused about is the depth of everything explained in chapter 12. There is so much information regarding how the router, switch, and hosts connect and how to look those up, but I have never set up a network before, and seeing the graphs doesn't explain anything to me. I've also been watching videos explaining the topic, but I keep running into the same problem. I understand it is Cisco, and they assume you have a base level of knowledge coming into this, but I am an absolute beginner learning as I go. So I can understand how the network is laid out, but I don't understand the interface and what they see after entering the sh cdp command. All it does is explain how to bring it up, but I still have trouble reading it as if I wanted to use that information to troubleshoot something. More time and exposure will help me, but going straight into the chapter was rough, unlike the previous chapters. This one is something I'll need to watch many YouTube videos to understand.
