Product Overview

The Cisco Nexus® 7700 F3-Series 24-Port 40 Gigabit Ethernet Module (referred to as the Cisco Nexus 7700F3‑Series module in this document) offers outstanding feature flexibility and wire-rate 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 Cisco Nexus 7700 platform is the latest extension to the Cisco Nexus 7000 Series modular switches. With more than 83 terabits per second (Tbps) of overall switching capacity, the Cisco Nexus 7700 platform delivers the highest-capacity 10, 40, and 100 Gigabit Ethernet ports in the industry, with up to 768 native 10-Gbps ports, 384 40-Gbps ports, and 192 100-Gbps ports. This high system capacity is designed to meet the scalability requirements of the largest cloud environments.

The Cisco Nexus 7700 switches have operation and feature consistency with the existing Cisco Nexus 7000 Series Switches, using a common system architecture, the same application-specific integrated circuit (ASIC) technology, and the same proven Cisco NX-OS Software releases.

The Cisco Nexus 7700 F3-Series module (Figure 1) is a low-latency, high-performance, high-density 40 Gigabit Ethernet module designed for the Cisco Nexus 7700 platform to deliver up to 384 wire-rate 40 Gigabit Ethernet ports in a single Cisco Nexus 7700 18-Slot Switch chassis (Table 1).

The Cisco Nexus 7700 F3-Series module is based on the Cisco Nexus F3-Series switch-on-chip (SoC) ASIC. Thistype of design increases performance while lowering the power and cooling requirements of the module. The Cisco Nexus F3-Series SoC is an innovative Cisco-designed 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 supports all the foundational networking protocols needed to build Layer 2 and Layer 3 networks, but it also can support highly virtualized environments, enabling virtual overlay networking with hardware support for Cisco Virtual Extensible LAN (VXLAN) and Locator/ID Separation Protocol (LISP) technologies. Cisco Nexus 7700 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 Service (VPLS).

The module delivers 1.44 billion packets per second (bpps) of distributed Layer 2 and Layer 3 forwarding and up to 960 Gbps of data throughput. A Cisco Nexus 7700 18-Slot Switch fully populated with the Cisco Nexus 7700 F3-Series module can deliver up to 23 bpps and 30.7 terabits per second (Tbps) of switching performance.

Features and Benefits

The Cisco Nexus 7700 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 their data center environments while migrating to dense multiservice 40 Gigabit Ethernet networks.

The Cisco Nexus 7700 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 7700 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 7700 F3-Series module can be used in conjunction with the Cisco Nexus 2000 Series Fabric Extenders (FEX). The Cisco Nexus 2000 Series is designed to simplify data center architecture and operations by dramatically reducing the number of points of management.

The Cisco Nexus 7700 F3-Series module supports port breakout. Up to 19 of the 24 physical ports on the module can be configured in breakout mode, each becoming 4 logical and independent 10 Gigabit Ethernet ports. This breakout mode can be configured at any time on any port (up to 19 ports) independently from configuration of other ports, and without the need to reload the module. When 19 ports of the module are configured in breakout mode, the other 5 ports remain available for establishing 40 Gigabit Ethernet links. Copper or fiber breakout assemblies are required to enable the physical separation of 10-Gigabit channels.

The Cisco Nexus 7700 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 7700 F3-Series module, FCoE can be deployed in director-class modular platforms for the access layer and core of converged networks.

The Cisco Nexus 7700 F3-Series module provides support for wire-rate 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 7700 F3-Series module supports high-performance MPLS for 40 Gigabit Ethernet data center deployments.

Support of Cisco LISP enables enterprises and service providers to simplify multi-homed routing and 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 7700 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 F3-Series module hardware. Please consult your Cisco representative to confirm the appropriate Cisco NX-OS Software release required to enable these features.
