The process of network diagram creationis well-known for the most network administrators. In this article, we will tryto answer the question: why an IT manager must know the network topology andalways should have it in front of his eyes. Also, we will review all the processof the network topology discovery and network diagram creation using thespecialized software. First of all, it is worth to mention, that the choice of network hardwareand software used in a company depends onthe network topology. But the topology, in its turn, depends on the companys needs and requirements. Thus, the competentnetwork topology increases theefficiency of all the organization and allows you not to distract yourcolleagues if one of the LAN components falls out. In addition, the intimateknowledge of the network topology allows the IT manager to evaluate itsbottlenecks, and to plan further connections of the network devices and PCsbetter. Apart from everything else, the system administrator has to detect andrecover any network failure as fast as possible. But if the companys networkis complex and consists of dozens or hundreds PCs, servers, switches, printers,and other devices, it is not always possible to understand what the problem isand where to go to recover the failure. With the network diagram you alwayscould view and try to understand where the defective device is, on which floor,in which office, etc. But what if you are a newbie in the organization or have been sent by outsourcingcompany to solve specified problems? In this case, discovering and building thenetwork diagram topology can take more than an hour, and if the network israther complex, this procedure can take even a few days. Are there anyinstruments that allow drawing the network diagram effortlessly? If there areswitches supporting the SNMP protocol on the network, the system administratorcan use the specialized network discoverysoftware that is available on the market. This software allows creatingnetwork diagrams automatically. All the process will take a few steps: 1. Install the network diagrammer program on the admins PC. 2. Scan your entire network inorder to detect all the network devices. If your switches support the SNMPprotocol, the program will detect connections between devices automatically. 3. If some connections between devices have not been detected because ofsome reasons (for instance, the existing security policy does not allow usingthe SNMP protocol on some devices), the system administrator can complete and draw the diagram manually using the internaldiagram editor. Also, he is able to arrange devices by groups as they arrangedby the rooms and offices in the companys building, draw areas, and addnecessary labels. The network topology diagramis ready. All the devices that are connected to the LAN, and links between themare located on the map. So, the network mapping process takes three steps only, but these 3steps can help you to improve your LAN reliability, your employees and theentire organization. Creating a network topologydiagram will save system administrators nerves and time, allowing him tosolve more important issues related to the network operation, such as,optimizing and upgrading the system, analyzing the LAN structure, maintainingthe technical documentation, etc.
