Product Review

The Cisco N3K-C3172PQ-XL offers a high-density configuration with 48 fixed 10 GbE SFP+ ports and 6 QSFP+ ports, catering to environments requiring extensive connectivity and bandwidth. However, its forwarding rate of up to 1 Bpps and switching capacity of 1.4 Tbps, while substantial, may not meet the demands of extremely high-throughput applications. Additionally, the switch supports a comprehensive feature set including 4096 VLANs and 288,000 MAC addresses, but its power consumption of 293 W and heat dissipation of 488 BTU/hour could be a concern in energy-sensitive deployments.


The Cisco N3K-C3172PQ-XL is a data center switch designed to deliver high performance, flexibility, and non-blocking 40 GbE bandwidth options for the most demanding data center environments. Engineered for scalability, the switch offers a comprehensive feature set, making it an ideal choice for enterprise and cloud service providers looking to optimize their data center infrastructure for virtualization, high-performance computing (HPC), and cloud computing. At the core of its hardware specifications, the switch boasts 48 fixed 10 GbE SFP+ ports and 6 fixed QSFP+ ports, providing ample connectivity options for a variety of network demands. These ports are complemented by a single 10/100/1000 management port, a RS-232 serial console port, and a USB port, facilitating easy setup, management, and diagnostics. The device is designed for efficiency and redundancy with two power supplies, ensuring uninterrupted operation and service continuity. The Cisco N3K-C3172PQ-XL occupies a 1 rack unit (RU) form factor, making it a compact solution for data centers where space is a premium. Despite its compact size, the switch does not compromise on performance, supporting a switching capacity of up to 1.4 Tbps and a forwarding rate of up to 1 Bpps. This capability ensures that data flows efficiently through the network, minimizing bottlenecks and improving overall performance.
  • Jumbo frames support up to 9216 bytes, enhancing data transfer efficiency for large data packets.
  • The switch can store up to 288,000 MAC addresses, supports up to 4096 VLANs, and can handle 512 Spanning Tree Protocol (RSTP) instances or 64 Multiple Spanning Tree Protocol (MSTP) instances, providing significant scalability and network segmentation options.
  • Advanced network features include support for up to 4,000 Access Control List (ACL) entries for ingress and 1,000 for egress, enabling detailed traffic filtering and security controls.
With a routing table capable of handling 16,000 prefixes and 16,000 host entries, along with 8000 multicast routes, the Cisco N3K-C3172PQ-XL is equipped to manage extensive network routing requirements. The switch also supports up to 64 EtherChannels with up to 16 ports per EtherChannel, allowing for flexible port aggregation to increase bandwidth and provide link redundancy. The hardware is backed by 8 GB of memory and a 12 MB shared buffer, ensuring smooth processing of network traffic even under heavy loads. The 16 GB boot flash provides ample storage for the operating system and applications. Operating power consumption is 293 W, with an AC input voltage range of 100 to 240 VAC, and DC input voltage options from -40 VDC to -72 VDC. Heat dissipation is rated at 488 BTU/Hour, and the switch operates efficiently within a temperature range of 0 °C to 40 °C. In summary, the Cisco N3K-C3172PQ-XL is a versatile, high-capacity switch designed to meet the rigorous demands of modern data centers. Offering a blend of performance, scalability, and reliability, it is engineered to support the next generation of data center and cloud deployments.
