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

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.

◦ 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.

◦ 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.

Feature

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.

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.

Benefits of Cisco NX-OS Software

Benefit

●

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

infrastructure

●

Transparent operation with existing network

●

Open standards

●

No compatibility concerns

Feature

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.

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.

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.

Using the Cisco Nexus Data Broker software and Cisco Plug-in for

OpenFlow agent, the Cisco Nexus 3048 Switch can be used to

build a scalable, cost-effective, and programmable tap or SPAN

aggregation infrastructure. This approach replaces the traditional

purpose-built matrix switches with these switches. You can

interconnect these switches to build a multilayer topology for tap

or SPAN aggregation infrastructure.

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.

Cisco Data Center Network Manager

The Cisco Nexus 3048 is supported in Cisco DCNM. Cisco DCNM is designed for hardware platforms enabled

for Cisco NX-OS, which consist of the Cisco Nexus Family of products. Cisco DCNM is a Cisco management

solution that increases overall data center infrastructure uptime and reliability, hence improving business

continuity. Focused on the management requirements of the data center network, Cisco DCNM provides a

robust framework and comprehensive feature set that meets the routing, switching, and storage administration

needs of present and future data centers. In particular, Cisco DCNM automates the provisioning process,

proactively monitors the LAN by detecting performance degradation, secures the network, and streamlines the

diagnosis of dysfunctional network elements.

Cisco Nexus Data Broker

The Cisco Nexus 3048 Switch with Cisco Nexus Data Broker can be used to build a scalable and cost-effective

traffic monitoring infrastructure using network taps and SPAN. This approach replaces the traditional purpose-built matrix switches with one or more OpenFlow-enabled Cisco Nexus switches. You can interconnect these

switches to build a scalable tap or SPAN aggregation infrastructure. You also can combine tap and SPAN

sources to bring the copy of the production traffic to this tap or SPAN aggregation infrastructure. In addition,

you can distribute these sources and traffic monitoring and analysis tools across multiple Cisco Nexus switches.
