A logical network diagram illustrates the flow of information through a network and shows how devices communicate with each other. It typically includes elements like subnets, network objects, and devices, routing protocols and domains, voice gateways, traffic flow, and network segments.

A logical network diagram usually shows network devices like routers, firewalls, and voice gateways. It shows subnets, VLAN IDs, subnet masks, and IP addresses. It also shows routing protocols, traffic flows, routing domains, and network segments. This information corresponds to the Network Layer (L3) of the OSI Model.

A physical network diagram shows how the network devices are physically connected together, and all ports on all devices on the network are represented. This includes cables, fiber, interfaces, patch panels, and other physical components. It will also show the topology exactly as it exists with physical links between devices.

A logical network diagram is used to manage the IP address space within the organization. It is also used to submit network-related proposals to management since they hide a lot of the physical details. They are appropriate for consideration for changes or expansion to the network. In addition, vendors will use logical network diagrams to submit proposals for clients’ consideration.

A physical network diagram is mainly used by IT staff to visually document the physical connections on the network. It is important to remember that both types of diagrams are used by IT together in order to diagnose network problems, identify potential threats and weak spots, and plan network changes and expansion.
