What Is the Cisco RD-DPX200-X100-K9?
The Cisco RD-DPX200-X100-K9 is a high-density 100G line card designed for the Cisco NCS 5500 Series routers, catering to service providers and enterprises requiring scalable, high-performance routing. This module supports 200Gbps full-duplex throughput per slot, leveraging Cisco’s Silicon One ASIC technology to deliver low-latency, energy-efficient packet processing for 5G, cloud, and IP/MPLS networks.
Key features include:
- 100G QSFP28 Port Density: 2x100G or 8x25G breakout configurations per port.
- Segment Routing (SRv6/SR-MPLS): Hardware-accelerated for scalable traffic engineering.
- Cisco IOS-XR Support: Enables programmable network slicing and automation.

Primary Use Cases and Deployment Scenarios
1. 5G Mobile Transport Networks
The module aggregates traffic from distributed radio units (DUs/CUs) into 5G core networks, providing <1ms latency for ultra-reliable low-latency communication (URLLC) services.
2. Cloud Metro Backbone
In metro DCI deployments, the RD-DPX200-X100-K9 supports EVPN-VXLAN overlays, enabling multi-tenant cloud connectivity with hardware-based encryption (MACsec).
3. IP/MPLS Peering Edge
For Tier 1 ISPs, the line card handles full internet routing tables (800k+ BGP routes) with TCAM optimization, reducing table-miss penalties by 40%.
Installation and Optimization Guidelines
Hardware Preparation
- Chassis Slot Compatibility: Install in slots 0–3 of the NCS 5516 chassis for optimal airflow.
- QSFP28 Transceivers: Use Cisco-certified optics (e.g., QSFP-100G-SR4-S=) to ensure BER <10^-15.
Configuration Best Practices
- Segment Routing: Enable SR-MPLS for traffic engineering:

Troubleshooting Common Issues
- Port Flapping: Check for incompatible transceivers or firmware mismatches.
- High CPU: Optimize ACLs using TCAM carving to offload processing to hardware.
Why the RD-DPX200-X100-K9 Outperforms Third-Party Line Cards
While white-box alternatives may offer lower upfront costs, Cisco’s solution provides:
- Silicon One Integration: Delivers 2x higher packets-per-second (PPS) than merchant silicon.
- Cisco Crosswork Automation: Simplifies large-scale SRv6 deployments via intent-based APIs.
- Lifetime Warranty: Covers hardware defects and performance degradation.

Field Insights: Balancing Scalability and Complexity
Deploying 80+ RD-DPX200-X100-K9 cards across a European ISP’s backbone reduced latency by 35% compared to older ASR 9000 modules. However, the transition revealed unexpected challenges: integrating IOS-XR’s segment routing with legacy MPLS-TE required rewriting 200+ route policies. Conversely, a competitor’s attempt to use third-party line cards in NCS 5500 chassis led to 15% packet loss during peak traffic—blamed on TCAM incompatibilities. For network architects, the RD-DPX200-X100-K9 isn’t just a line card; it’s the backbone of next-gen infrastructure, where cutting corners risks obsolescence.
