C3KX-NM-10G Use Case
Data Center Top-of-Rack 10G Uplink Aggregation with C3KX-NM-10G
In a midsize data center, IT teams leverage the Catalyst 3K-X 10G Network Module option PID C3KX-NM-10G to aggregate multiple Top-of-Rack access switches over 10 Gbps links. By consolidating traffic from dozens of 1 Gbps server ports, they eliminate oversubscription, achieve non-blocking performance and sub-millisecond latency for east-west traffic. The outcome is streamlined virtual machine mobility, improved application responsiveness and seamless capacity growth.
Campus Core Backbone Upgrade to 10 Gbps with C3KX-NM-10G
A university network team installs the Catalyst 3K-X 10G Network Module option PID C3KX-NM-10G in core switches to interconnect academic buildings via 10 Gbps fiber links. This high-speed backbone supports bandwidth-intensive applications—IP video, research data transfers and distance learning—while maintaining sub-5 ms campus-wide latency. The result is consistent user experience, streamlined digital collaboration and scalable infrastructure for future academic initiatives.
Branch Office SD-WAN Uplink Enhancement Using C3KX-NM-10G
A retail branch deploys Catalyst 3K-X switches equipped with the C3KX-NM-10G network module to provision dual 10 Gbps SD-WAN uplinks to the corporate MPLS core. This design ensures high-bandwidth, low-latency connectivity for point-of-sale, voice and cloud applications, with automatic failover. The benefit is enhanced application performance, simplified policy enforcement via Cisco DNA Center and maximized business continuity.
