Cisco Nexus N3K‑C3172TQ‑10GT Description
The Cisco Nexus N3K‑C3172TQ‑10GT is designed to deliver high‑density 10 Gigabit Ethernet connectivity directly over copper RJ‑45 interfaces, providing cost‑effective and efficient network access for servers, storage arrays, and backbone aggregation. Its 48 10GBASE‑T ports support multiple Ethernet speeds (100 Mbps / 1 Gbps / 10 Gbps), reducing dependency on optical transceivers while maximizing deployment flexibility.
In addition to its copper interfaces, the switch offers 6 QSFP+ uplink ports that can operate natively at 40 GbE or be configured for 4×10 GbE breakout, enabling scalable uplink bandwidth for spine‑leaf architectures or core aggregation layers. This makes it ideal for leaf switches in modern data center designs.
Powered by Cisco NX‑OS, the N3K‑C3172TQ‑10GT provides advanced networking capabilities including robust Layer 2 switching, Layer 3 routing, VLAN segmentation, QoS, ACL enforcement, virtual network support, and programmability for automation workflows. The switch is built for performance, reliability, and operational simplicity in enterprise IT and service provider networks.
