Enterprise Campus Network - Three-Tier Hierarchy
About This Architecture
Enterprise campus network using a three-tier hierarchy with Palo Alto PA-3200 firewall protecting DMZ servers and core infrastructure. Traffic flows from ISP through the firewall to H3C S6520 core switches, then through L3 aggregation switches to L2 access switches serving endpoints across seven VLANs. This architecture isolates office, finance, R&D, management, WiFi, web, and database traffic while maintaining high availability through dual core and aggregation switch pairs. Fork and customize this diagram on Diagrams.so to match your campus topology, security policies, and VLAN segmentation requirements.

How do I design a three-tier enterprise campus network with firewall protection and VLAN segmentation?
This diagram shows a three-tier hierarchy where a Palo Alto PA-3200 firewall protects DMZ servers and core infrastructure, traffic flows through redundant H3C S6520 core switches, then through L3 aggregation switches to L2 access switches. Seven VLANs isolate office, finance, R&D, management, WiFi, web, and database traffic for security and performance.
