Cisco Nexus 3172TQ N3K-C3172TQ-10GT 10/40Gb Ethernet Switch

Brand:

The Cisco Nexus 3172TQ (N3K-C3172TQ-10GT) is a high-density 10G data center switch with 48 copper ports and 6x 40G uplinks. Designed for enterprise and cloud environments, it delivers low latency, high throughput, and scalable Layer 2/3 performance for modern infrastructure needs.

OVERVIEW

  • The Cisco Nexus 3172TQ (N3K-C3172TQ-10GT) is a compact yet powerful 1RU data center switch engineered for high-density 10 Gigabit Ethernet environments and modern spine-leaf architectures. As part of the Cisco Nexus 3000 Series, it provides predictable low-latency forwarding and wire-speed performance for demanding enterprise and cloud workloads.
  • It combines 48 x 10GBase-T ports with 6 x 40G QSFP+ uplinks, enabling efficient server connectivity while supporting high-speed aggregation into spine or core layers. This balance of copper access density and high-speed uplinks makes it suitable for virtualization clusters, private cloud infrastructure, and enterprise core networks requiring consistent throughput and scalability.
  • Compared to similar Nexus access-layer models, this switch stands out for its high 10GBase-T port density, flexible 40G uplink scalability, and optimized latency profile—making it a strong fit for organizations modernizing legacy data center fabrics or expanding cloud-ready architectures.
