Network Topology Diagrams

Network topology diagrams map the physical or logical layout of a network — switches, routers, firewalls, links, and subnets — so everyone from NOC engineers to management can understand the infrastructure at a glance. ChatDiagram generates these diagrams from a natural-language description of your network.

How to

How to use a network diagram template.

  1. 01Name the topology type

    Specify the layout: "draw a star topology with a central switch and eight end devices" or "draw a spine-leaf data-centre topology".

  2. 02Label devices and interfaces

    Ask to label each node with its hostname or role ("Core-SW1", "FW-DMZ") and each link with its speed ("10 GbE", "1 GbE").

  3. 03Add VLANs or subnets

    Describe segmentation: "show VLAN 10 (servers) and VLAN 20 (users) as separate groups connected at the distribution layer".

  4. 04Include the internet edge

    Mention ISP uplinks, firewalls, and DMZ zones and the AI places them at the correct boundary in the diagram.

  5. 05Export for runbooks or Confluence

    Download as PNG or SVG to embed in network runbooks, disaster-recovery plans, or Confluence pages.

FAQ

Questions about network diagram templates

What is the difference between physical and logical topology?

Physical topology shows how devices are physically cabled. Logical topology shows how data flows, which may differ (e.g., a physical star network can be a logical ring with token-passing). Specify which view you need when prompting ChatDiagram.

Can I draw a spine-leaf data-centre topology?

Yes. Describe the number of spine and leaf switches and the AI generates a spine-leaf diagram with full-mesh uplinks from every leaf to every spine.

How do I show redundant links?

Ask for "dual uplinks from each access switch to the distribution layer" and ChatDiagram draws two parallel lines between those nodes.

Does ChatDiagram support SD-WAN diagrams?

Yes. Describe the SD-WAN overlay — controller, edge nodes, underlay transport — and the blockdiagram engine renders the logical overlay with dashed lines for virtual tunnels.
