Enterprise wireless network topology integrating Cisco Catalyst switches, FortiGate firewall, and WLC-managed access points across four VLANs for data, guest, voice, and IoT traffic. Traffic flows from Internet through FortiGate (203.0.113.1/30) into Core Switch 9500, then through Distribution Switch 9300 and WLC 9800-L to three Access Switches (2960X) serving laptops, mobile devices, VoIP phones, and IoT sensors. This architecture demonstrates hierarchical network design with VLAN segmentation (VLAN 10 data, VLAN 20 guest, VLAN 30 voice, VLAN 40 IoT) and CAPWAP-managed access points (9120AX, 9130AX, 9115AX) across multiple floors. The design separates management traffic (10.0.0.0/24, 10.0.99.0/24) from user data, enabling QoS policies, security policies, and scalable wireless coverage.

Consider adding redundant uplinks and spanning-tree tuning for production deployments.
