A single network environment may have four or five diagrams, each depicting different aspects of the topology. Differences between physical and logical: A physical diagram shows you the actual devices involved and the cables that connect them to each other. These include: 1. What Is a Project Schedule Network Diagram? It includes the start, duration, and finish of each task on a timeline. One of the most common types of networks is called local area network (LAN). In the Open Systems Interconnection (OSI) model, logical network diagrams correlate with the information contained in layer 3 (L3). ), L2 switches (Only the management interface can be presented), First open the configuration file (ASW1 in this case), Pick-up every single IP-address definition for the interfaces. It also allows you to easily and intuitively draw your network diagram. Network Logic - Project Management Knowledge. To be able to create a logical network diagram, you first need to have following information: 1. You are able to plan changes quickly and accurately. One of the most helpful techniques for creating a network plan is to draw a picture of it. Usually, once an L3 diagram has been completed, you will see immediately which parts are not logically redundant, etc. Convert the Logic Diagram using NAND logic gate. Troubleshooting is easier than before. It shows subnets, VLAN IDs, subnet masks and IP addresses. L3 device configurations– text files or access to GUI, etc. The diagram uses a library containing specific symbols to represent network equipment , media and the end-user devices such as computers (PC, mac, laptop) , network printer, hubs, server and finally a modem. As I also said in the Physical Diagram article: I prefer to use the term “logical” instead of “L3” because it is more easily understood by somebody unfamiliar with the OSI model.
