Product Review

The Cisco N3K-C3164Q-40GE switch boasts a substantial switching capacity of 5.12 Tbps and a forwarding rate up to 3.8 Bpps, supporting high-performance computing and networking demands. With 64 fixed 40 GbE QSFP+ ports and extensive support for VLANs, ACLs, and EtherChannels, it offers comprehensive network configuration options. However, its high power consumption at 803 W and significant heat dissipation of 2739 BTU/Hour may require careful consideration in environments with limited cooling capabilities or energy efficiency requirements.


The Cisco N3K-C3164Q-40GE is a high-performance networking switch designed for data centers and high-end enterprise environments. This model is equipped with 64 fixed 40 GbE QSFP+ ports, providing a substantial bandwidth capacity for demanding applications and data throughput requirements. It is designed in a 2 rack unit (RU) form factor, optimizing space efficiency in data centers while delivering powerful networking capabilities. One of the key features of this switch is its impressive switching capacity of 5.12 terabits per second (Tbps), combined with a forwarding rate of up to 3.8 billion packets per second (Bpps). This ensures high-speed data processing and transfer rates, suitable for environments with heavy data traffic. The device supports jumbo frames up to 9216 bytes, enhancing data transmission efficiency over the network. For network administrators, the Cisco N3K-C3164Q-40GE offers extensive management and connectivity options, including: - One 10/100/1000 management port for out-of-band management, - One RS-232 serial console port for local system access, - Two USB ports for external storage or configuration file management. The switch is equipped with two redundant power supplies, ensuring continuous operation and minimizing downtime in case of a power supply failure. It operates on an AC input voltage of 200 to 240 VAC and has a power consumption of 803 watts. The heat dissipation rate is 2739 BTU/hour, highlighting its efficiency in energy use and cooling requirements. Network segmentation and security are enhanced through support for up to 4096 VLANs and extensive Access Control List (ACL) configurations, ranging from 4,000 to 16,000 ingress entries and 1,000 to 4,000 egress entries. This allows for granular control over network traffic and resource access. Additionally, the switch supports up to 507 Rapid Per-VLAN Spanning Tree (RPVST+) instances and 64 Multiple Spanning Tree Protocol (MSTP) instances, facilitating efficient network topology management and loop prevention. The Cisco N3K-C3164Q-40GE boasts a robust routing and address table, capable of accommodating up to 128,000 Longest Prefix Match (LPM) routes, 120,000 IP host entries, and 96,000 MAC address entries. This vast capacity ensures scalability and flexibility in handling large networks with diverse routing requirements and device connectivity. For link aggregation, the switch allows the configuration of up to 256 EtherChannels, with the ability to include up to 32 ports per EtherChannel. This feature enhances bandwidth and provides redundancy, improving network resilience and performance. The hardware specifications include 16 GB of memory and a 48 MB shared buffer size, supporting the high-speed processing of data packets and temporary storage for efficient data handling. The switch's dimensions are 3.48 x 17.41 x 22.32 inches, and it weighs 37 pounds. It is designed to operate within a temperature range of 0 °C to 40 °C, ensuring reliability in various environmental conditions.
