C3KX-NM-10G= Use Case
High-Density Data Center Server Farm Aggregation
In a mid-size enterprise data center running virtualization and containerized applications, the C3KX-NM-10G module aggregates twenty 1G server uplinks into dual 10G trunks on the Catalyst 3K-X switch. This consolidation reduces cable sprawl, cuts port count by 80%, and delivers predictable low-latency performance for VM migrations and storage replication. Outcome: scalable 10Gbps aggregation, streamlined operations, and accelerated time-to-market for new services.
Campus Distribution Uplink for Unified Communications
A large university deploying 802.11ax wireless and VoIP services installs Catalyst 3K-X switches in each building with the C3KX-NM-10G module to establish redundant 10G uplinks to the core backbone. This high-throughput backbone supports bandwidth-intensive e-learning platforms, HD video conferencing, and seamless campus roaming. Outcome: sub-millisecond voice latency, future-proof Wi-Fi capacity, and guaranteed campus-wide service availability.
Multi-Tenant Virtualization Backbone in Service Provider Networks
A managed services provider leverages C3KX-NM-10G modules on Catalyst 3K-X switches to deliver VXLAN-based multi-tenant connectivity across its point-of-presence (PoP) network. Dual 10G uplinks separate overlay and underlay traffic, enabling isolation of up to 100 tenant networks with end-to-end QoS and encryption. Outcome: robust 10GbE transport, simplified network segmentation, and SLA-driven performance for high-value customers.
