Product Review

The Cisco N3K-C3172TQ-32T offers a comprehensive solution with its 32 fixed 10GBase-T RJ-45 ports and 6 QSFP+ ports, supporting a wide range of connectivity options for diverse networking needs. However, its forwarding rate of up to 1 Bpps and switching capacity of 1.4 Tbps, while substantial, may not meet the requirements of networks with extremely high data throughput demands. Additionally, the switch's power consumption at 440 W and heat dissipation of 1228 BTU/hour could raise operational costs and necessitate efficient cooling solutions in dense deployments.


The Cisco N3K-C3172TQ-32T is a high-performance, 1 Rack Unit (RU) switch designed for efficient network operation. It is part of Cisco's Nexus 3000 series, focusing on providing high density and low latency for top-of-rack (ToR) deployment in data centers. This switch is equipped with 32 fixed 10GBase-T RJ-45 ports for high-speed connectivity and 6 QSFP+ ports to facilitate high-capacity uplinks, making it suitable for intensive workloads and high-speed storage tasks. Key hardware specifications include: - 32 Fixed 10GBase-T RJ-45 ports for server connectivity and network aggregation. - 6 QSFP+ ports for uplink connections, supporting high-speed networking demands. - 1 10/100/1000 management port, 1 RS-232 serial console port, and 1 USB port for device management and configuration. The Cisco N3K-C3172TQ-32T boasts a switching capacity of 1.4 Terabits per second (Tbps) and a forwarding rate of up to 1 Billion packets per second (Bpps), ensuring rapid data transmission across the network. It supports jumbo frames up to 9216 bytes, enhancing data transfer efficiency for large data packets. With support for 288,000 MAC addresses and 4096 VLANs, this switch can manage large-scale network segmentation and ensure secure, organized data traffic. It also supports up to 512 Rapid Spanning Tree Protocol (RSTP) instances and 64 Multiple Spanning Tree Protocol (MSTP) instances, providing network redundancy and resilience. For security and traffic management, the Cisco N3K-C3172TQ-32T accommodates 4,000 ingress and 1,000 egress Access Control List (ACL) entries. It also features a comprehensive routing table with capacity for 16,000 prefixes and host entries, along with 8000 multicast routes, facilitating efficient network routing and multicast applications. The switch supports up to 64 EtherChannels with up to 16 ports per EtherChannel, allowing for flexible link aggregation configurations that enhance bandwidth and provide link redundancy. It is equipped with 4 GB of memory and a 12 MB shared buffer size to ensure smooth processing of network traffic. The boot flash of 2 GB aids in reliable system boot and operation. Designed for energy efficiency, the switch operates on 440 Watts of power, with an AC input voltage range of 100 to 240 VAC and a DC input range of -40 VDC to -72 VDC. Its heat dissipation is 1228 BTU per hour, ensuring that the device maintains optimal performance within an operating temperature range of 0 °C to 40 °C. The inclusion of two redundant power supplies enhances system reliability, minimizing downtime in case of a power supply failure. In summary, the Cisco N3K-C3172TQ-32T offers a combination of high-speed connectivity, extensive feature support, and operational efficiency, making it an ideal choice for data centers requiring high-performance, scalable networking solutions.
