Greenfield Multi-VLANNetwork Design

A distributed network designed from the ground up with multi-VLAN segmentation and granular access, built on Aruba CX and FortiSwitch hardware.

A greenfield build is the only chance to get segmentation right before traffic patterns harden. Different classes of traffic needed to be isolated from the start, with access granted deliberately rather than inherited from a flat network.

• 01Multi-VLAN segmentation separating traffic classes across the estate.
• 02Aruba CX and FortiSwitch forming the access and distribution layer.
• 03Granular access design controlling which segments can reach which services.
• 04Distributed design carried consistently across locations.

• Designed the VLAN scheme and segmentation model for the environment.
• Configured Aruba CX and FortiSwitch infrastructure to the design.
• Implemented granular inter-segment access control.
• Delivered the network as part of a wider greenfield infrastructure build.

The organisation runs on a segmented distributed network where access between traffic classes is explicit by design.
