Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Cisco Nexus 3000 Series Switches overview

The Cisco Nexus® 3000 Series Switches are a comprehensive portfolio of 1, 10, 40, and 100 Gigabit Ethernet switches built from a Switch-on-a-Chip (SoC) architecture. Introduced in April 2011, this series of switches provides line-rate Layer 2 and 3 performance and is suitable for Top-of-the-Rack (ToR) architecture.

Cisco Nexus 3132C-Z product overview

Cisco Nexus 3132C-Z product overview

The Cisco Nexus 3132C-Z is the 32-port 100-Gbps programmable architecture switch, enabled with major data center features designed for software-defined data centers. This 1-Rack-Unit (1RU) model offers wire-rate Layer 2 and 3 switching.

The Cisco Nexus 3132C-Z (Figure 1) is a Quad Small Form-Factor Pluggable (QSFP) switch with 32 QSFP28 ports. Each QSFP28 port can operate at 10, 25, 40, 50, and 100 Gbps, up to a maximum of 128 x 25-Gbps ports.

Cisco NX-OS software overview

Cisco NX-OS is a data center–class operating system built with modularity, resiliency, and serviceability at its foundation. Cisco NX-OS helps ensure continuous availability and sets the standard for mission-critical data center environments. The self-healing and highly modular design of Cisco NX-OS makes zero-impact operations a reality and provides exceptional operational flexibility.

Focused on the requirements of the data center, Cisco NX-OS provides a robust and comprehensive feature set that meets the networking requirements of present and future data centers. With an XML interface and a Command-Line Interface (CLI) like that of Cisco IOS® Software, Cisco NX-OS provides state-of-the-art implementations of relevant networking standards as well as a variety of true data center–class Cisco innovations.

Main benefits

The Cisco Nexus 3132C-Z provides the following:

      Data center feature richness that supports full IPv4 and IPv6 routing; Virtual Extensible LAN (VxLAN); and hardware-based encapsulation, including Multiprotocol Label Switching (MPLS), Virtual Private LAN Service (VPLS), Generic Routing Encapsulation (GRE), and Q-in-Q tunneling

      Wire-rate Layer 2 and 3 switching on all ports,2 with up to 6.4 Terabits per second (Tbps) and up to 2 billion packets per second (bpps)

      Robust programmability, with support for Cisco NX-API, Linux containers, XML and JavaScript Object Notation (JSON) APIs, the OpenStack plug-in, Python, and Puppet and Chef configuration and automation tools

      High performance and scalability with a four-core CPU, 16 GB of DRAM, and 32 Mb of dynamic buffer allocation, making the switch excellent for massively scalable data centers and big data application


    The QSFP28 port can be configured to work as 4 x 25-Gbps ports, offering deployment flexibility, with up to a maximum of 128 x 25-Gbps ports.

    Both fiber and copper cabling solutions are available for 10-, 25-, 40-, 50-, and 100-Gbps connectivity, including Active Optical Cable (AOC) and Direct-Attached Cable (DAC).

      High availability

    Virtual Port Channel (vPC) technology provides Layer 2 multipath 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. This feature allows organizations to prevent network bottlenecks, increase resiliency, and add capacity with little network disruption.

    Advanced reboot capabilities include hot and cold patching and fast reboot capabilities.

    The switch uses hot-swappable Power-Supply Units (PSUs) and fans.

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

    Power-on Autoprovisioning (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 utilization 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.

    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).

2.Wire rate on all ports for packets greater than 200 bytes.

Transceiver and cabling options

The Cisco Nexus 3132C-Z has 32 QSFP28 ports. QSFP28 technology allows a smooth transition from 40 to 100 Gigabit Ethernet infrastructure in data centers. Each of the Cisco Nexus 3132C-Z switch’s QSFP28 ports can operate in native 100, 4 x 25, 4 x 10, or 2 x 50 Gigabit Ethernet mode. In addition to the QSFP28 technology, the Cisco Nexus 3132C-Z also supports 40/100G Bidi to help customers run 40G and 100G at the same time in their Data Centers.

This switch supports both fiber and copper cabling solutions for these two modes. 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 QSFP28 ports to 10 Gigabit Ethernet switches or hosts using a splitter cable that has an Enhanced QSFP (QSFP+) transceiver on one end and four SFP+ transceivers on the other end. Similar capability can be achieved on the fiber solution by using QSFP+ SR4 transceivers on both ends and procuring third-party fiber splitter MPO-to-LC cables. Table 2 lists the transceiver types supported.
