Product Review

The Cisco N3K-C3172TQ-XL switch offers a high density of 48 fixed 10GBase-T RJ-45 ports and 6 QSFP+ ports, catering well to environments requiring a large number of direct connections and high-speed uplinks. However, its power consumption at 440W and heat dissipation of 1228 BTU/hour could be a concern in densely packed data centers or environments with limited cooling capabilities. Additionally, with a switching capacity of 1.4 Tbps and a forwarding rate of up to 1 Bpps, it supports high throughput, but the limited buffer size of 12 MB might pose challenges in bursty traffic scenarios.


The Cisco N3K-C3172TQ-XL is a versatile and efficient networking solution designed for modern data centers. It is a 1 Rack Unit (RU) switch that offers high-density 10GBase-T connectivity, along with 40G QSFP+ uplinks, making it ideal for high-performance computing environments. This switch comes equipped with 48 fixed 10GBase-T RJ-45 ports that provide flexible and scalable 10GbE connectivity. For uplink capabilities, it includes 6 fixed QSFP+ ports, facilitating high-speed data transfer and network uplinks to aggregate traffic from multiple devices or networks. Management of the device is streamlined through a single 10/100/1000 management port, a RS-232 serial console port, and a USB port, enabling various options for device configuration and management. Power efficiency and redundancy are also critical features of the Cisco N3K-C3172TQ-XL. It is equipped with two power supplies, ensuring uninterrupted operation and system reliability. The switch's operating power is 440W, with an AC input voltage range of 100 to 240 VAC and a DC input voltage range of -40 VDC to -72 VDC. This versatility in power input options ensures that the switch can be deployed in a wide range of power environments. Its heat dissipation is rated at 1228 BTU/Hour, indicating its efficiency in managing thermal output. In terms of performance, the Cisco N3K-C3172TQ-XL boasts a switching capacity of 1.4 Tbps and a forwarding rate of up to 1 Bpps. This high level of performance is supported by a large forwarding information base, including support for 288,000 MAC addresses, 4,096 VLANs, and extensive ACL entries for both ingress (4,000) and egress (1,000) traffic. The switch supports jumbo frames up to 9216 bytes, enhancing its ability to handle large data packets efficiently. Routing capabilities on the Cisco N3K-C3172TQ-XL are robust, with a routing table that accommodates 16,000 prefixes and host entries, along with 8,000 multicast routes. This allows for efficient routing and forwarding of diverse traffic types across the network. The switch also supports a significant number of EtherChannels (64) and ports per EtherChannel (16), enabling high-capacity link aggregation for increased bandwidth and link redundancy. Memory and storage specifications include 4 GB of memory and a 2 GB boot flash, complemented by a 12 MB shared buffer size. These specifications ensure smooth operation and sufficient storage for the system's software and configuration files.
  • Support for up to 288,000 MAC addresses and 4,096 VLANs ensures extensive network segmentation and security options.
  • High forwarding rate of up to 1 Bpps and switching capacity of 1.4 Tbps accommodate high volumes of traffic, minimizing bottlenecks.
  • Dual power supplies provide redundancy, minimizing downtime and ensuring continuous network operation.
Overall, the Cisco N3K-C3172TQ-XL is engineered for reliability, performance, and flexibility, making it an excellent choice for data centers looking to optimize their 10GbE and 40GbE network infrastructure.
