C3850-NM-2-10G Use Case
Enterprise Campus Uplink Expansion for High-Density Wi-Fi and IoT
Scenario: A large university campus upgrading its Catalyst 3850 stack to support 802.11ax access points and hundreds of IoT sensors. By installing the C3850-NM-2-10G 2×10GE network module, network engineers provision redundant 10 Gbps uplinks to the core aggregation layer. Outcome: Delivers sustained high-bandwidth throughput, sub-millisecond latency and seamless failover—supporting 1 000+ APs and IoT devices while future-proofing the wireless and sensor infrastructure.
Data Center Leaf-Spine Aggregation for Scalable East-West Traffic
Scenario: A mid-sized data center requires non-blocking leaf-to-spine connectivity for virtualization and East-West application traffic. Integrating the C3850-NM-2-10G into Catalyst 3850 leaf switches provides dual 10 Gbps uplinks to the spine fabric. Outcome: Enables a scalable, low-latency architecture with up to 20 Gbps of aggregated capacity per leaf device, simplifies topology management in Cisco DNA Center, and supports high-density VM and container workloads.
Virtualized Branch Office Converged WAN and UC Connectivity
Scenario: A distributed enterprise branch deploys voice-over-IP, video conferencing and virtualized applications over MPLS and broadband links. The Catalyst 3850 equipped with the C3850-NM-2-10G module provides dual 10 Gbps uplinks for active/standby WAN circuits and dedicated QoS-aware voice/video tunnels. Outcome: Ensures resilient, high-performance unified communications and data services, with granular traffic policing and sub-5 ms convergence for mission-critical branch operations.
