Documentation Tree
The employees in your building are having difficulty accessing a web server on the network. You look for the network documentation that the previous network engineer used before he transitioned to a new job; however, you cannot find any network documentation whatsoever.
Therefore, you decide to create your own network record-keeping system. You decide to start at the access layer of your network hierarchy. This is where redundant switches are located, as well as the company servers, printers, and local hosts.
You create a matrix to record your documentation and include access layer switches on the list. You also decide to document switch names, ports in use, cabling connections, root ports, designated ports, and alternate ports.
