About This Architecture

Multi-VLAN office network using Aruba, D-Link, and TP-Link switches to segment traffic across five isolated broadcast domains: Office (VLAN 10), Production (VLAN 20), Guest Wi-Fi (VLAN 30), Surveillance (VLAN 40), and IP Phones (VLAN 50). Internet traffic flows through a firewall to the Aruba Instant On 1960 core switch, which distributes to nine access-layer switches and four wireless access points serving different VLANs. This architecture isolates critical production devices and surveillance systems from guest traffic, reducing broadcast storms and improving security posture. Fork and customize this diagram on Diagrams.so to match your switch models, VLAN assignments, and device inventory. The design demonstrates best-practice network segmentation for mid-sized offices balancing performance, security, and manageability.

How do I design a multi-VLAN office network that separates office, production, guest, surveillance, and VoIP traffic?

This diagram shows a hierarchical network with an Aruba Instant On 1960 core switch feeding nine access-layer switches and four wireless APs, each serving specific VLANs. VLAN 10 (Office) and VLAN 20 (Production) isolate critical devices, VLAN 30 (Guest Wi-Fi) contains untrusted traffic, VLAN 40 (Surveillance) protects cameras and NVR, and VLAN 50 (IP Phones) ensures voice quality—all protected by
