Product Review

The Cisco N3K-C3132Q-40GE switch offers a high-density configuration with 32 fixed 40 GbE QSFP+ ports and a notable switching capacity of 2.5 Tbps, catering to environments requiring high bandwidth and throughput. However, its limited number of SFP+ ports (4) and a single management port might restrict flexibility in mixed network environments. Additionally, the switch supports a comprehensive feature set including 4,096 VLANs, ample MAC addresses (288,000), and a sizable routing table, but the operational power consumption of 210 W and heat dissipation of 717 BTU/hour could be a concern for energy-conscious deployments.


The Cisco N3K-C3132Q-40GE is a high-performance, 1 Rack Unit (RU) switch designed for efficient data center operations. It features 32 fixed 40 GbE QSFP+ ports for high-density, scalable 40 Gigabit Ethernet deployments. Additionally, it includes 4 SFP+ ports, providing flexibility for uplink or 10 Gigabit Ethernet connectivity, crucial for modern data center networks. This switch is equipped with a single 10/100/1000 management port, a RS-232 serial console port, and a USB port, facilitating easy setup, management, and troubleshooting. The hardware is engineered to support a substantial switching capacity of 2.5 Terabits per second (Tbps), ensuring smooth data transmission across networks. Its forwarding rate reaches up to 1.4 Billion packets per second (Bpps), which allows for efficient handling of high-volume traffic without bottlenecks. The Cisco N3K-C3132Q-40GE is capable of handling jumbo frames up to 9216 bytes, providing improved performance for large data transfers. It supports a large MAC address table with 288,000 entries, along with 4096 VLANs, making it suitable for complex network environments. The switch can manage up to 512 Rapid Spanning Tree Protocol (RSTP) instances and 64 Multiple Spanning Tree Protocol (MSTP) instances, ensuring network resilience and reliability. For security and traffic management, the switch allows for 4,000 ingress and 1,000 egress Access Control List (ACL) entries. Its routing capabilities are robust, with a routing table that accommodates 16,000 prefixes and host entries, along with 8000 multicast routes. This feature set makes it ideal for layer 3 network segmentation and routing between VLANs. The Cisco N3K-C3132Q-40GE supports up to 64 EtherChannels with a maximum of 16 ports per EtherChannel, enabling high-capacity link aggregation for increased bandwidth and link redundancy. The switch is equipped with 4 GB of memory and a 12 MB shared buffer size, optimizing its performance in handling concurrent network demands. For storage, it provides 4 GB of boot flash memory. In terms of power efficiency, the switch operates on 210 Watts, with an AC input voltage range of 100 to 240 VAC and a DC input voltage range of -40 VDC to -72 VDC. Its heat dissipation is measured at 717 BTU per hour, highlighting its energy-efficient design. The compact size of 1.72 x 17.3 x 19.7 inches allows for dense rack configurations without sacrificing space efficiency. It can operate within a temperature range of 0 °C to 40 °C, ensuring reliability in various data center environments. Key hardware features include: -
