WS-C3850-16XS-E Use Case
Data Center Top-of-Rack 10G Aggregation with WS-C3850-16XS-E
In a mid-sized data center, network architects deploy the WS-C3850-16XS-E Catalyst 3850 16-Port 10G Fiber Switch IP Services as a top-of-rack aggregation node. It consolidates 16 SFP+ server uplinks at full 10 Gbps line rate, supports hardware VXLAN termination and advanced IP Services routing, and integrates redundant power and StackWise-480. Benefit: Delivers ultra-low latency, deterministic throughput and high availability for east-west traffic, accelerating VM migrations and reducing network bottlenecks.
Campus Distribution Backbone with Catalyst 3850 16-Port 10G Fiber Switch
A large university campus leverages the WS-C3850-16XS-E as its primary distribution-layer switch, aggregating multiple building access switches over 10G fiber. With OSPF/EIGRP dynamic routing, Cisco TrustSec segmentation and Quality of Service (QoS) policies, the switch ensures consistent performance for wired and wireless services. Benefit: Simplifies network design, enhances security through macro-segmentation, and delivers guaranteed bandwidth for high-density Wi-Fi, VoIP and video applications.
Secure Branch Office Routing and Segmentation over 10G Fiber
A global enterprise deploys the WS-C3850-16XS-E at branch campuses to terminate 10 Gbps fiber uplinks and enforce multi-tenant security zones. Using IP Services features—VRF-Lite for isolated routing, advanced ACLs, and hardware-accelerated IPsec VPN—the switch segments voice, data and IoT traffic. Benefit: Strengthens branch-level security, reduces MPLS/WAN costs by offloading traffic directly to cloud services, and maintains deterministic performance for critical applications.
