C9300-NM-2Q Use Case
Campus Core Aggregation with Catalyst 9300 2 x 40GE Uplinks
A large university deploys the C9300-NM-2Q on Catalyst 9300 switches as dual 40 Gigabit Ethernet uplinks between building distribution and core layers. This configuration consolidates high-density Wi-Fi, BYOD and IoT traffic into a single, resilient spine, eliminating bottlenecks during peak lecture and lab sessions. Outcome: sub-millisecond latency, 3× performance headroom and simplified campus expansion without forklift upgrades.
Retail Data Center Spine-and-Leaf Uplink for Cloud Migration
A nationwide retail chain migrates its point-of-sale and inventory applications to a private cloud. By installing the Catalyst 9300 2 × 40GE Network Module in access switches, each leaf node attains high-capacity uplinks to the spine layer. Benefit: 50% faster transaction processing, consistent SLA-grade connectivity and non-disruptive scaling across 500+ store locations.
Hybrid Cloud Interconnect for Financial Services
A financial services firm integrates on-premise trading platforms with AWS and Azure to support high-frequency trading and analytics. The C9300-NM-2Q module on Catalyst 9300 switches delivers dual 40GE links over DWDM circuits to public cloud edge routers. Result: sub-millisecond round-trip times, 2× aggregate throughput and strict micro-segmentation for regulatory compliance.
