Cisco NCS 5700 24X400GE Base Line Card | 400GbE Routing — NC57-24DD=

Scale high-speed routing capacity with the Cisco NCS 5700 24X400GE Base Line Card, a dense 24-port 400 GbE line card built for the NCS 5700 platform. It is designed for environments where bandwidth growth is not theoretical: backbone transport, large-scale aggregation, and high-volume interconnects that need serious port density in a disciplined footprint. For network teams, the value is straightforward. More 400 GbE interfaces per line card means fewer slots consumed for the same traffic objective, which can simplify platform planning and preserve expansion headroom. That matters in core and edge routing designs where every slot, every cable path, and every upgrade window has operational cost. This line card is a strong fit for organizations standardizing on Cisco routing infrastructure and looking to extend the life of a high-capacity chassis with current-generation 400 GbE connectivity. It is the kind of component that justifies itself in networks where throughput, density, and rack efficiency directly affect service delivery and capital planning.
