Product Overview

The Cisco Nexus® 3172PQ, 3172TQ, 3172TQ-32T, 3172PQ-XL, and 3172TQ-XL Switches are dense, high­performance, 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.

Five Cisco Nexus 3172 switches are available:

●

The Cisco Nexus 3172PQ (Figure 1) is a 10-Gbps Enhanced Small Form-Factor Pluggable (SFP+)–based
ToR switch with 48 SFP+ ports and 6 Quad SFP+ (QSFP+) ports. Each SFP+ port can operate in 100­Mbps, 1-Gbps, or 10-Gbps mode, and each QSFP+ port can operate in native 40-Gbps or 4 x 10-Gbps
mode. This switch is a true phy-less switch that is optimized for low latency and low power consumption.

Transceiver and Cabling Options

The Cisco Nexus 3172 switches support a wide variety of 1, 10, and 40 Gigabit Ethernet connectivity options.1 and
10 Gigabit Ethernet connectivity is achieved in the first 48 ports, and 40 Gigabit Ethernet connectivity is achieved
using QSFP+ transceivers in the last 6 ports.

QSFP+ technology allows a smooth transition from 10 to 40 Gigabit Ethernet infrastructure in the data center. The
Cisco Nexus 3172 switches support connectivity over copper and fiber cables, providing excellent physical-layer
flexibility. For low-cost cabling, copper-based 40-Gbps Twinax cables can be used, and for longer cable reaches,
short-reach optical transceivers are excellent.

Connectivity can be established from the QSFP ports to an upstream 10 Gigabit Ethernet switch using a splitter
cable that has a QSFP transceiver on one end and four SFP+ transceivers on the other end. Similar capability can
be achieved using optical transceivers by procuring third-party fiber splitters. In addition, 1G and 10G interfaces
can be supported on QSFP ports with the Cisco CVR-QSFP-SFP10G adapter.
