The Cisco Nexus® 3172PQ, 3172TQ, 3172TQ-32T, 3172PQ-XL, and 3172TQ-XL Switches are dense, high-performance, 10- and 40-Gbps Layer 2 and 3 switches that are members of the Cisco Nexus 3100 switch platform. All switches offer improved port density and scalability in compact one-rack-unit (1RU) form factors. The Cisco Nexus 3172 switches run the industry-leading Cisco® NX-OS Software operating system, which helps ensure continuous availability and sets the standard for mission-critical data center environments. They are well suited for data centers that require cost-effective, power-efficient line-rate Layer 2 and 3 top-of-rack (ToR) switches. These switches also support forward and reverse airflow (port-side exhaust and port-side intake) schemes with AC and DC power inputs.
The Cisco Nexus 3000 Series switch N3K-C3172PQ-10GE with 48x 10GB SFP+ ports and 6x 40GB QSFP+ interfaces, providing a switching capacity of up to1.4 Tbps with a forwarding rate of up to 1 Bpps. The Back-to-Front Airflow design ensures efficient cooling for optimal device operation,The MAC Address Table Size is capable of handling 288,000 entries while offering low-latency performance thanks to its 4 GB system memory. This high-performance switch is designed for demanding networking environments where speed and reliability are essential components in managing network traffic effectively.
