Cisco C9610-LC-32CD - Combo line card

Cisco Part Number: C9610-LC-32CD is a C9610 Series Smart Switches combo line card

Introducing the Cisco C9610 Series Smart Switches—a new generation of high-performance hardware built to elevate campus networking with unmatched port density and superior bandwidth capacity. Engineered for the demands of the AI-driven enterprise, these switches deliver seamless support for 25G and 100G uplinks and include forward-looking readiness for 400G, ensuring your network infrastructure is fully prepared for the future.

Cisco C9610-LC-32CD Line Card

The Cisco C9610-LC-32CD is a next-generation high-density line card engineered for the Cisco Catalyst 9610R chassis, delivering exceptional performance, flexibility, and scalability for modern campus core and aggregation networks. Designed as the updated version of the C9600X-LC-32CD, this model features enhanced airflow, improved hardware layout, and optimized thermal performance—ideal for environments demanding high-capacity QSFP-based connectivity.

Key Capabilities

The C9610-LC-32CD provides a powerful blend of port versatility and non-blocking throughput, supporting:

• 30 × 100/40G QSFP28 ports
• 2 × 200G ports (QSFP-DD, module-dependent¹)
• 2 × 400G ports (QSFP-DD)

This high-capacity configuration enables organisations to support multi-gigabit access layers, next-gen Wi-Fi backhaul, data-intensive workloads, and robust inter-building connectivity.

Flexible Deployment Options

The line card is built for modular scalability, enabling multiple deployment scenarios:

• Full line-rate performance across all 32 QSFP28 ports, ideal for high-speed upstream and downstream connectivity.
• Port conversion capability, allowing four QSFP28 ports to be combined into two QSFP-DD ports for 200/400G uplinks to service provider or data centre switches.
• Purpose-built for high-density campus core or edge designs relying heavily on QSFP optics.

Performance Highlights

When paired with the Cisco C9610-SUP-3 or C9610-SUP-3XL supervisor modules, the line card delivers:

• Up to 3.2 Tbps full-duplex throughput
• Non-blocking switching across all supported ports

A mix of:

• 32 × QSFP28 ports; or
• 28 × QSFP28 + 2 × QSFP-DD ports depending on configuration

Ideal Use Cases

• Large enterprise campus core networks
• High-speed aggregation layers
• Fiber-rich environments requiring QSFP28 and QSFP-DD
• Scalable uplinks to service provider or data centre infrastructure

Notes

¹ Actual support for 200GE depends on transceiver module availability.

The Cisco C9610-LC-32CD delivers the high-density, high-performance, and flexible connectivity required for demanding enterprise network architectures—ensuring long-term scalability and investment protection.
