Product Overview

The Cisco Nexus® 3048 Switch (Figure 1) is a line-rate Gigabit Ethernet top-of-rack (ToR) switch and is part of the Cisco Nexus 3000 Series Switches portfolio. The Cisco Nexus 3048, with its compact one-rack-unit (1RU) form factor and integrated Layer 2 and 3 switching, complements the existing Cisco Nexus family of switches. This switch runs the industry-leading Cisco® NX‑OS Software operating system, providing customers with robust features and functions that are deployed in thousands of data centers worldwide. The Cisco Nexus 3048 is ideal for big data customers that require a Gigabit Ethernet ToR switch with local switching that connects transparently to upstream Cisco Nexus switches, providing an end-to-end Cisco Nexus fabric in their data centers. This switch supports both forward and reversed airflow schemes with AC and DC power inputs.

Main Benefits

The Cisco Nexus 3048 provides the following main benefits:

Wire-rate Layer 2 and 3 switching

- Layer 2 and 3 switching of up to 176 Gigabit per second (Gbps) and more than 132 million packets per second (mpps) in a compact 1RU form-factor switch

Robust and purpose-built Cisco NX-OS operating system for end-to-end Cisco Nexus fabric

- Transparent integration with the Cisco Nexus family of switches to provide a consistent end-to-end Cisco Nexus fabric

- Modular operating system built for resiliency

- Integration with Cisco Data Center Network Manager (DCNM) and XML management tools

Comprehensive feature set and innovations for next-generation data centers

- Virtual PortChannel (vPC) 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.

- Power On 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.

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

- EtherAnalyzer 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.

- Full 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).

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 2 summarizes the benefits that Cisco NX-OS offers.

Table 2. 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 7000, 5000, 4000, 3000, 2000, and 1000V Series.

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 supports Simple Network Management Protocol (SNMP) Versions 1, 2, and 3 MIBs.

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
