Product Overview

The Cisco Nexus® 3172PQ and 3172TQ Switches are dense, high-performance Layer 2 and 3, 10- and 40-Gbps switches that are members of the Cisco Nexus 3100 switch platform. Both switches offer improved port density and scalability in compact one-rack-unit (1RU) form factors. These Cisco Nexus 3172 switches run the industry-leading Cisco® NX-OS Software operating system that 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. Both also support forward and reverse airflow schemes (port-side exhaust and port-side intake) with AC and DC power inputs.

Two Cisco Nexus 3172 switches are available:

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 100-Mbps, 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.

Main Benefits

The Cisco Nexus 3172 switches provide the following main benefits:

Wire-rate Layer 2 and 3 switching on all 72 10 Gigabit Ethernet ports

- The Cisco Nexus 3172 switches provide Layer 2 and 3 switching of up to 1.4 terabits per second (Tbps) and up to 1 billion packets per second (bpps) in a compact 1RU form factor.

High availability

- Virtual PortChannel (vPC) technology provides Layer 2 multipathing through the elimination of Spanning Tree Protocol. It also enables fully utilized bisectional bandwidth and simplified Layer 2 logical topologies without the need to change the existing management and deployment models.

- The 64-way equal-cost multipath (ECMP) routing enables the use of Layer 3 fat-tree designs that allows organizations to prevent network bottlenecks, increase resiliency, and add capacity with little network disruption.

- Advanced reboot capabilities included through In Service Software Upgrade (ISSU) and Fast Reboot capabilities.

- Power-supply units (PSUs) and fans are hot swappable.

High performance

- The Cisco Nexus 3172 switches deliver ultra-low nominal latency, which allows customers to implement high‑performance infrastructure for high-frequency trading (HFT) workloads.

Purpose-built on Cisco NX-OS operating system with comprehensive, proven innovations

- PowerOn Auto Provisioning (POAP) enables touchless bootup and configuration of the switch, drastically reducing provisioning time.

- Cisco Embedded Event Manager (EEM) and Python scripting enable automation and remote operations in the data center.

- Advanced buffer monitoring reports real-time buffer use per port and per queue, which allows organizations to monitor traffic bursts and application traffic patterns.

- Ethanalyzer is a built-in packet analyzer for monitoring and troubleshooting control-plane traffic and is based on the popular Wireshark open source network protocol analyzer.

- Precision Time Protocol (PTP; IEEE 1588) provides accurate clock synchronization and improved data correlation with network captures and system events.

- Complete Layer 3 unicast and multicast routing protocol suites are supported, including Border Gateway Protocol (BGP), Open Shortest Path First (OSPF), Enhanced Interior Gateway Routing Protocol (EIGRP), Routing Information Protocol Version 2 (RIPv2), Protocol Independent Multicast sparse mode (PIM-SM), Source-Specific Multicast (SSM), and Multicast Source Discovery Protocol (MSDP).

Configuration

The Cisco Nexus 3172 switches have the following configurations:

Cisco Nexus 3172PQ

- 48 fixed 10 Gigabit Ethernet SFP+ ports (can operate at 100-Mbps, 1-Gbps, and 10-Gbps speeds)

- Six fixed QSFP+ ports (each QSFP+ port can support 4 x 10 Gigabit Ethernet or 40 Gigabit Ethernet)

Cisco Nexus 3172TQ

- 48 fixed 10GBASE-T ports (can operate at 100-Mbps, 1-Gbps, and 10-Gbps speeds)

Support for both forward (port-side exhaust) and reversed (port-side intake) airflow schemes is available.

Transceiver and Cabling Options

The Cisco Nexus 3172 switches support a wide variety of 1, 10, and 40 Gigabit Ethernet connectivity options. 1 and 10Gigabit 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 infrastructures in the data center. TheCisco 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.

Table 1 lists the QSFP transceiver types supported.
