Every link type on one fabric

A compact topology that exercises the full link vocabulary — fiber with speed and port tags, a LAG bundle, a wireless association, an 802.1Q trunk carrying VLANs, a PoE drop to a camera, and a site-to-site VPN tunnel — each rendered with its own line style.

A network diagram is only as useful as the link annotations — "are these two switches on fiber or copper, trunk or access, what VLANs, what speed." Schematex encodes all of it after the : on a connection, and renders each link type distinctly.

One line, many semantics. fiber 10G port: Gi0/1>Gi1/0/1 draws the orange ticked fiber style and prints both the speed and the two interface names. lag 20G thickens the line for a bundled uplink. wireless and vpn go dashed; poe carries power to the camera; trunk vlan: 10,20 tags the 802.1Q VLAN list.

Validation comes free. VLAN ids are range-checked (1–4094) and the engine never silently drops a port, link, or device — if you wrote it, it's on the diagram or it's a reported error.
