FAQs

Q: What is the difference between the N3K-C3172TQ-10GT and N3K-C3172PQ models?
A: The N3K-C3172TQ-10GT features 48x 10GBASE-T copper RJ-45 ports, ideal for connecting servers with copper interfaces. The N3K-C3172PQ features 48x SFP+ fiber ports instead, offering more flexibility for fiber optic connections.

Q: Can the 10GBASE-T ports operate at lower speeds?
A: Yes, all 48 RJ-45 ports are multi-rate and support 100 Mbps, 1 Gigabit, and 10 Gigabit Ethernet speeds, providing backward compatibility with existing infrastructure.

Q: What NX-OS software features are supported on this switch?
A: The switch runs Cisco NX-OS and supports advanced Layer 2 and Layer 3 features including VXLAN bridging, Quality of Service (QoS), comprehensive routing protocols (OSPF, BGP, RIP), and extensive management options via CLI, web interface, and SNMP.

Q: Is this switch suitable for top-of-rack data center deployments?
A: Absolutely. The Nexus 3172TQ is specifically designed as a cost-effective, power-efficient top-of-rack switch for data centers requiring line-rate Layer 2 and 3 performance with 10G server connectivity and 40G uplinks.

Q: What airflow options are available?
A: The switch supports both forward airflow (port-side exhaust) and reverse airflow (port-side intake) configurations with corresponding AC and DC power supply models, allowing flexible deployment in hot-aisle or cold-aisle data center designs.
