How to use a network diagram template.
- 01Start with a template
Choose from our gallery of pre-built ESXi network diagram examples that match your configuration.
- 02Customize physical and virtual switches
Add, remove, or rename vSwitches, distributed switches, port groups, and VLAN IDs as needed.
- 03Connect uplinks and interfaces
Drag network adapters, LAGs, and teaming policies to reflect your exact hardware setup.
- 04Annotate traffic flows
Label storage, management, and vMotion paths to make the diagram self-explanatory.
- 05Collaborate and export
Share a live link with your team or export a PNG/SVG for documentation and RFCs.
Questions about network diagram templates
What does a typical VMware ESXi network diagram include?
It normally shows physical NICs, virtual switches (standard or distributed), port groups, VLANs, and the traffic types (management, vMotion, storage, VM traffic). LACP LAGs and teaming policies are also common.
How do I diagram VLANs in ESXi?
In ChatDiagram, each VLAN is represented as a labeled port group on a virtual switch. You can color-code them and attach notes specifying the VLAN ID and allowed hosts.
Can I show both standard and distributed switches?
Absolutely. Our examples include mixed environments. You can drop in a Distributed Switch object and connect ESXi hosts to it, while leaving some traffic on local standard switches.
Is it possible to illustrate iSCSI storage traffic separately?
Yes. Use distinct ethernet segments or port groups with an ‘iSCSI’ label. Many examples, like the distributed switch with iSCSI storage, demonstrate how to isolate storage traffic for security and performance.
How do LACP LAGs appear in the diagram?
LAGs are drawn as bundled links between a host’s physical adapters and the upstream switch, with a notation like ‘LACP active’. The diagram generator includes pre-built LAG elements you can drag onto your canvas.
