Based on Cisco® Cloud Scale technology, the Cisco Nexus® 9348GC-FXP-B1 Switch is the first Power-over-Ethernet (PoE) fixed switch in the next-generation Cisco Nexus 9300 platform. Continuing the success of the Cisco Nexus 9300 EX platform, the Cisco Nexus 9300 FX platform PoE switch is built on modern system architecture designed to provide high performance, support cost-effective deployments, and meet the evolving needs of entry-level enterprise, midmarket, and small branch-office networks.
The Cisco Nexus 9348GC-FXP-B1 allows connectivity to Ethernet powered devices, including Cisco IP phones, wireless access points, and video cameras. The product supports prestandard PoE devices and is IEEE 802.3af and IEEE 802.3at-compliant. With PoE, you no longer need to have wall power to each PoE-enabled device, and thus the expense for additional electrical cables and circuits is no longer necessary in IP phone and WLAN deployments. Power injectors and PoE midspans are also no longer required. With optimized efficiency, simplified operation and installation, and a wide array of device versatility, the 9348GC-FXP-B1 provides investment protection for customers in an ever-changing data-centric and increasingly connected market. The expansive feature set includes 40 MB of intelligent buffering, support for voice VLANs, a full-featured Layer 2 and Layer 3 Application-Specific Integrated Circuit (ASIC), and dual 1100-watt (W) power supplies that provide up to 2000W of PoE power.
Cisco provides two modes of operation for Cisco Nexus 9000 Series Switches. Organizations can use Cisco NX-OS Software to deploy the switches in standard Cisco Nexus switch environments (NX-OS mode). Organizations also can use a hardware infrastructure that is ready to support the Cisco Application Centric Infrastructure (Cisco ACI™) platform to take full advantage of an automated, policy-based, systems-management approach (ACI mode).

◦ Advanced buffer monitoring reports real-time buffer use per port and per queue, which allows organizations to monitor traffic bursts and application traffic patterns.
◦ Complete Layer 3 unicast and multicast routing protocol suites are supported, including 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).
◦ Segment routing allows the network to forward Multiprotocol Label Switching (MPLS) packets and engineer traffic without Resource Reservation Protocol (RSVP) Traffic Engineering (TE). It provides a control-plane alternative for increased network scalability and virtualization.
◦ Fibre Channel and Fibre Channel over Ethernet (FCoE) N-Port Virtualization (NPV) support enables the network administrator to control domain IDs and points of management on a Fibre Channel network as it scales. This feature enables LAN and SAN converged networks on a lossless, reliable Ethernet network.
◦ Network traffic monitoring with Cisco Nexus Data Broker builds simple, scalable, and cost-effective network Test Access Points (TAPs) and Cisco Switched Port Analyzer (SPAN) aggregation for network traffic monitoring and analysis.
◦ Automate the time-consuming tasks of creating, installing, and maintaining appropriate fabricwide switch configurations with the new Cisco Nexus Fabric Manager.
● Cisco Application Centric Infrastructure (Cisco ACI) solution
◦ Cisco ACI offers a holistic architecture in the data center with centralized automation and policy-based application profiles
◦ Cisco ACI provides a robust, transport network for today’s dynamic workloads. Cisco ACI is built on a network fabric that combines time-tested protocols with new innovations to create a highly flexible, scalable, and resilient architecture of low-latency, high-bandwidth links. This fabric delivers a network that can support the most demanding and flexible data center environments.

The Cisco Nexus 9300 FX platform supports the NX-OS operating system. NX-OS interoperates with any networking operating system, including Cisco IOS® Software that conforms to the networking standards described in this data sheet.
NX-OS is a purpose-built data center operating system designed for performance, resiliency, scalability, manageability, and programmability at its foundation. It provides a robust and comprehensive feature set that meets the demanding requirements of virtualization and automation in present and future data centers.
The Cisco Nexus 9000 Series Switches use an enhanced version of NX-OS with a single binary image that supports every switch in the series, simplifying image management. The operating system is modular, with a dedicated process for each routing protocol: a design that isolates faults while increasing availability. In the event of a process failure, the process can be restarted without loss of state. The operating system supports hot and cold patching and online diagnostics.
The software packaging for the Cisco Nexus 9000 Series offers flexibility and a comprehensive feature set while being consistent with Cisco Nexus access switches. The default system software has a comprehensive Layer 2 security and management feature set. To enable additional functions, including Layer 3 IP unicast and IP multicast routing and Cisco Nexus Data Broker, you must install additional licenses. Table 3 lists the software packaging and licensing available to enable advanced features.
Cisco® Application Centric Infrastructure (ACI) is a holistic architecture with centralized automation and policy-based application profiles. The Cisco ACI fabric is designed from the foundation to support emerging industry demands while maintaining a migration path for architecture already in place. The fabric is designed to support the industry move to management automation, programmatic policy, and dynamic “workload-anywhere” models. The Cisco ACI fabric accomplishes this with a combination of hardware, policy-based control systems, and software closely coupled to provide advantages not possible in other models.
The fabric consists of three major components: the Cisco Application Policy Infrastructure Controller (APIC), spine switches, and leaf switches. These three components handle both the application of network policy and the delivery of packets. Organizations can use the ACI-ready Cisco Nexus® 9000 Series Switches as spine or leaf switches to take full advantage of an automated, policy-based, systems management approach. The Cisco Nexus 9300 Series Switches include both spine and leaf switches. For detailed information, please refer here.
