Product overview

The Cisco Nexus® 31128PQ Switch is a dense, high-performance Layer 2 and 3, 10- and 40-Gbps switch that is a member of the Cisco Nexus 3100 switches. The Nexus 3100 switches are the second-generation Cisco Nexus 3000 series switches and offer improved port density, scalability, and features compared to the first-generation switches. The Cisco Nexus 31128PQ comes in a compact two-rack-unit (2RU) form factor and runs the industry-leading Cisco® NX-OS Software operating system, providing customers comprehensive features and functions that are widely deployed. It supports both forward and reverse (port side exhaust and port side intake) airflow schemes with AC and DC power inputs. The Cisco Nexus 31128PQ is well suited for data centers that require a cost-effective, power-efficient line-rate Layer 2 and 3 access or leaf switch.

The Cisco Nexus 31128PQ (Figure 1) is a 10-Gbps Enhanced Small Form-Factor Pluggable (SFP+) and 40-Gbps Quad Small Form-Factor Pluggable (QSFP+) based switch with 96 SFP+ ports and 8 QSFP+ ports.

Main benefits

The Cisco Nexus 31128PQ provides the following main benefits:

      Wire-rate Layer 2 and 3 switching on all ports[1]

    Layer 2 and 3 switching of up to 2.5 Terabits per second (Tbps) and up to 1.4 Billion packets per second (bpps) is provided in a compact 2RU form-factor switch.

      High availability

    Virtual PortChannel (vPC) technology provides Layer 2 multipathing through the elimination of Spanning Tree Protocol and 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 and allows organizations to prevent network bottlenecks, increase resiliency, and add capacity with little network disruption.

    Hot swappable Power-Supply Units (PSUs) and fans.

      High Performance

    The Cisco Nexus 31128PQ delivers low nominal latency, which enables customers to implement high-performance infrastructure for High-Frequency Trading (HFT) and High-Performance Computing (HPC) workloads.

      Purpose-built 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 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.

    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 31128PQ has the following configuration:

      96 fixed 10 Gigabit Ethernet SFP+ ports

      8 fixed 40 Gigabit Ethernet QSFP+ ports

      Locator, Status and Environment LEDs

      Dual redundant power supplies

      Redundant (1+1) fans (2 rotors per fan)

      One 10/100/1000-Mbps management port

      One RS-232 serial console port

      Two USB ports

Both forward (port-side exhaust) and reversed (port-side intake) airflow schemes are supported.

Transceiver and cabling options

The Cisco Nexus 31128PQ has 8 QSFP+ ports. QSFP+ technology allows a smooth transition from 10 to 40 Gigabit Ethernet infrastructures in 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.

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 enables exceptional operation 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.

Cisco NX-OS Software Benefits

Table 1 summarizes that benefits that Cisco NX-OS offers.

Table 1.        Benefits of Cisco NX-OS Software

Feature

Benefit

Common software throughout the data center: Cisco NX-OS runs on all Cisco data center switch platforms (Cisco Nexus 9000, 7000, 6000, 5000, 4000, 3000 and 1000V Series Switches and Cisco Nexus 2000 Series Fabric Extenders).

  Simplification of data center operating environment
  End-to-end Cisco Nexus and Cisco NX-OS fabric
  No retraining necessary for data center engineering and operations teams

Software compatibility: Cisco NX-OS interoperates with Cisco products running any variant of Cisco IOS Software and also with any networking OS that conforms to the networking standards listed as supported in this data sheet.

  Transparent operation with existing network infrastructure
  Open standards
  No compatibility concerns

Modular software design: Cisco NX-OS is designed to support distributed multithreaded processing. Cisco NX-OS modular processes are instantiated on demand, each in a separate protected memory space. Thus, processes are started and system resources allocated only when a feature is enabled. The modular processes are governed by a real-time preemptive scheduler that helps ensure timely processing of critical functions.

  Robust software
  Fault tolerance
  Increased scalability
  Increased network availability

Troubleshooting and diagnostics: Cisco NX-OS is built with unique serviceability functions to enable network operators to take early action based on network trends and events, enhancing network planning and improving Network Operations Center (NOC) and vendor response times. Cisco Smart Call Home and Cisco Online Health Management System (OHMS) are some of the features that enhance the serviceability of Cisco NX-OS.

  Quick problem isolation and resolution
  Continuous system monitoring and proactive notifications
  Improved productivity of operations teams

Ease of management: Cisco NX-OS provides a programmatic XML interface based on the NETCONF industry standard. The Cisco NX-OS XML interface provides a consistent API for devices. Cisco NX-OS also provides support for Simple Network Management Protocol (SNMP) Versions 1, 2, and 3 MIBs. In addition NX-API and Linux Bash are now supported.

  Rapid development and creation of tools for enhanced management
  Comprehensive SNMP MIB support for efficient remote monitoring

Role-Based Access Control (RBAC): With RBAC, Cisco NX-OS enables administrators to limit access to switch operations by assigning roles to users. Administrators can customize access and restrict it to the users who require it.

  Tight access control mechanism based on user roles
  Improved network device security
  Reduction in network problems arising from human errors

Cisco NX-OS Software Packages for Cisco Nexus 31128PQ

The Cisco NX-OS Software packages available with the Cisco Nexus 31128PQ offer flexibility and a comprehensive feature set as well as consistency with Cisco Nexus access switches. The default system software has a comprehensive Layer 2 feature set with robust security and management features. To enable Layer 3 IP unicast and multicast routing functions, additional licenses need to be installed. Table 2 summarizes the software packages.
