The Cisco Nexus® 7000 F3-Series 6-Port 100 Gigabit Ethernet Module (referred to as the Cisco Nexus 7000 F3‑Series module in this document) offers outstanding feature flexibility and performance on each port. The module enables the deployment of high-density, low-latency, scalable data center architecture.

Powering Cisco’s Unified Fabric Architecture

The Cisco Nexus 7000 Series Switches are the foundation of the Cisco® Unified Fabric solution. Designed to meet the requirements of mission-critical data centers, these switches deliver exceptional availability, outstanding scalability, and the proven and comprehensive Cisco NX-OS Software data center switching feature set.

The first in the next generation of data center switching platforms, the Cisco Nexus 7000 Series provides integrated resilience combined with features optimized specifically for availability, reliability, scalability, and ease of management. The Cisco Nexus 7000 Series Switches’ fabric architecture scales beyond 17 terabits per second (Tbps) and is designed to support high-density 10, 40, and 100 Gigabit Ethernet deployments. Up to 768 native 10‑Gbps ports, 192 40-Gbps ports, and 96 100-Gbps ports can be supported in a single Cisco Nexus 7000 Series chassis.

The Cisco Nexus 7000 F3-Series module (Figure 1) is a low-latency, high-performance, high-density 100 Gigabit Ethernet module. It is operationally consistent with the Cisco Nexus 7700 F3-Series modules and shares a common system architecture and the same application-specific integrated circuit (ASIC) technology. Up to 96 100 Gigabit Ethernet ports are supported in a single Cisco Nexus 7000 18-Slot Switch chassis (Table 1).

The Cisco Nexus 7000 F3-Series module is based on the Cisco Nexus F3-Series switch-on-chip (SoC) ASIC. This type of design increases performance while lowering the power and cooling requirements of the module. The Cisco Nexus F3-Series SoC is an innovative Cisco ASIC powered by a flexible packet engine, which makes it excellent for building the network infrastructure for public and private cloud environments. The Cisco Nexus F3-Series engine can support all the foundational networking protocols needed to build Layer 2 and Layer 3 networks, and it also supports highly virtualized environments with virtual overlay networking, hardware support for Cisco Virtual Extensible LAN (VXLAN) and Locator/ID Separation Protocol (LISP). Cisco Nexus 7000 F3-Series hardware enables customers to transparently interconnect their data centers with protocols such as Overlay Transport Virtualization (OTV) and Multiprotocol Label Switching (MPLS) and Virtual Private LAN Services (VPLS).

The module delivers 900 million packets per second (mpps) of distributed Layer 2 and Layer 3 forwarding and up to 600 Gbps of data throughput.

Features and Benefits

Note:    N7K-SUP2 or N7K-SUP2E is required to support F3-series modules in the chassis.

The Cisco Nexus 7000 F3-Series Module integrates a broad set of data center switching technologies, including industry standards and Cisco’s own innovations. It combines the benefits of classical fabric interface line cards with the advanced routing features of edge interface modules. With this integration, the module provides exceptional investment protection for organizations consolidating data center environments while migrating to dense multiservice 100 Gigabit Ethernet networks.

  • The Cisco Nexus 7000 F3-Series module is powered by the proven and comprehensive Cisco NX-OS feature set. This extremely comprehensive set of Layer 2 and Layer 3 functions makes this module excellent for data center networks, in which density, performance, and continuous system operation are critical.
  • The Cisco Nexus 7000 F3-Series module is a critical enabler of Cisco FabricPath. With Cisco FabricPath, organizations can build resilient, flexible, and if needed, massively scalable Layer 2 networks. Cisco FabricPath protects enterprises’ investments by allowing existing spanning-tree-based deployments to be connected to a Cisco FabricPath network.
  • The Cisco Nexus 7000 F3-Series module can be used in conjunction with the Cisco Nexus 2000 Series Fabric Extenders (FEX). The Cisco Nexus 2000 Series Fabric Extenders are designed to simplify data center architecture and operations by dramatically reducing the number of points of management.
  • The Cisco Nexus 7000 F3-Series module delivers integrated Fibre Channel over Ethernet (FCoE), greatly simplifying the network infrastructure and reducing costs by enabling the deployment of unified data center fabrics to consolidate data center traffic onto a single, general-purpose, high-performance, highly available network. With the Cisco Nexus 7000 F3-Series module, FCoE can be deployed in director-class modular platforms for the access layer and core of converged networks.
  • The Cisco Nexus 7000 F3-Series module provides support for VXLAN offering the architectural flexibility needed to expand cloud deployments with repeatable pods in different Layer 2 domains. VXLAN can also enable migration of virtual machines between servers across Layer 3 networks.
  • The support of advanced data center interconnect (DCI) protocols such as Cisco OTV and VPLS makes the module excellent for helping customers simplify the extension of applications across geographically dispersed data center sites.
  • The Cisco Nexus 7000 F3-Series module supports high-performance MPLS for 100 Gigabit Ethernet data center deployments.
  • Support for Cisco LISP allows enterprises and service providers to simplify multi-homed routing, and it facilitates scalable any-to-any WAN connectivity while supporting data center virtual machine mobility.
  • The virtual device context (VDC) feature helps enable the virtualization of a single physical device in one or more logical devices. Each provisioned logical device is configured and managed as if it were a separate physical device.
  • The Cisco Nexus 7000 F3-Series module offers exceptional security, with integrated hardware support for:

◦     Configurable Control-Plane Policing (CoPP), which protects the supervisor CPU from excessive traffic

◦     Access control list (ACL) counters and logging capability to provide deeper packet visibility

◦     Layer 2 to Layer 4 ACL for both IPv4 and IPv6 traffic

◦     Cisco TrustSec® technology and ACL processing for security group tags (SGTs)

Note:    This document describes capabilities of the Cisco Nexus 7000 F3-Series module hardware. Please consult your Cisco representative to confirm the appropriate Cisco NX-OS Software release required to enable these features.
