Cisco Nexus 3048 Switch Data Sheet

 

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.

◦    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).

●      Network traffic monitoring with Cisco Nexus Data Broker

◦    Build simple, scalable and cost-effective network tap or Cisco Switched Port Analyzer (SPAN) aggregation for network traffic monitoring and analysis.

Configuration

●      48 fixed 10/100/1000-Mbps Ethernet ports

●      4 fixed Enhanced Small Form-Factor Pluggable (SFP+) ports

●      Locator LED

●      Dual redundant power supplies

●      Fan tray with redundant fans

●      Two 10/100/1000-Mbps management ports^*

●      One RS-232 serial console port

●      One USB port

●      Locator LED and button

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

Transceiver and cabling options

For uplink connectivity, the Cisco Nexus 3048 supports SFP+ direct-attach 10 Gigabit Ethernet copper, an innovative solution that integrates transceivers with Twinax cables into an energy-efficient and low-cost solution. For longer cable runs, multimode and single-mode optical SFP+ transceivers are supported. Table 1 lists the supported 10 Gigabit Ethernet transceiver options.

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. For more details, visit https://www.cisco.com/go/nexusdatabroker.
