C1-N3K-C3172PQ Overview
C1-N3K-C3172PQ Order-Code Identity
C1-N3K-C3172PQ identifies a Cisco ONE Nexus 3172PQ configuration. Cisco's exact PID description specifies 48 SFP+ ports and six QSFP+ ports. Each SFP+ interface supports 100 Mbps, 1 Gigabit Ethernet or 10 Gigabit Ethernet; each QSFP+ interface supports native 40 Gigabit Ethernet or four 10 Gigabit Ethernet lanes.
Performance and Standard-Memory Hardware
The Nexus 3172PQ data sheet lists 1.4 Tbps switching capacity, forwarding up to 1 billion packets per second and line-rate Layer 2 and Layer 3 traffic. This non-XL platform has 4 GB system memory, 2 GB boot flash and a 12 MB shared buffer. The XL PID is a separate product with 8 GB memory and 16 GB boot flash, so the two codes should not be substituted without review.
Power, Airflow and Lifecycle Checks
The platform supports two redundant power supplies and forward or reverse airflow choices. Cisco lists 143 W typical operating power and 293 W maximum power for the 3172PQ. Cisco's lifecycle notice names C1-N3K-C3172PQ and gives February 28, 2026 as its last date of support; buyers should therefore confirm condition, software entitlement, support expectations and an approved migration plan before ordering.
- Match the complete C1-N3K-C3172PQ PID and do not quote the XL model as an equivalent.
- Specify SFP+/QSFP+ optics or breakout cables separately according to the port plan.
- Align fan and power-supply airflow direction; mixed airflow parts are not an acceptable configuration.
- Document whether the requirement is a legacy replacement, spare or migration project because normal Cisco support has ended.
