The Cisco C3KX-NM-10G is a high-density network module designed to expand 3750-X and 3560-X Series switches with 4 × 10-Gbps SFP+ uplinks. This module empowers enterprise access and distribution switches to handle bandwidth-intensive tasks, such as server uplinks, data center aggregation, and high-speed fiber interconnects.
With support for Cisco’s enterprise feature set, the C3KX-NM-10G supports link aggregation (LACP), spanning tree, QoS, and layer-3 routing (when the parent switch supports it). The module is hot-swappable and operates with Cisco’s modular switch architecture, enabling non-disruptive upgrades and scalability. It’s ideal for organizations that require high-speed uplink ports without replacing their existing Catalyst 3750-X or 3560-X infrastructure.
