Network Maps
In our brief discussion about network placement, we have already looked at several different network maps. A network map, or network diagram, is a diagram showing all technical resources on a network and how they are connected.
There is no better way to determine the placement of your packet sniffer than to be able to visualize the network clearly. If you have a network map available to you, I would highly recommend keeping it handy, as it will become a valuable asset in the troubleshooting and analysis process. You may even want to make a detailed network map of your own network. Remember, sometimes half the battle in troubleshooting is pinpointing the problem.
