Description
The Cisco NC57-18DD-SE is a high-capacity 400 Gigabit Ethernet (400G) scale line card designed for the Cisco Network Convergence System (NCS) 5700 Series. Built for hyperscale and service provider environments, this line card delivers massive throughput with enhanced forwarding scale to support large routing tables, advanced services, and future-ready architectures.
Featuring 18x 400G ports or flexible configurations supporting up to 30x 100G/200G ports, the NC57-18DD-SE provides up to 7.2 Tbps of throughput per line card. Its scale (SE) architecture includes expanded forwarding resources, making it ideal for IP backbone, peering, aggregation, and data center interconnect deployments.
Powered by Cisco IOS XR Software, the NC57-18DD-SE supports advanced routing, segment routing, telemetry, automation, and high availability—enabling operators to scale networks efficiently while maintaining deterministic performance.
