The Cisco Nexus® 7700 M3-Series 24-Port 40 Gigabit Ethernet Module is a versatile I/O module with a comprehensive feature set that offers wire-rate performance on each port. The module provides deep buffers and high-capacity Ternary Content- Addressable Memory (TCAM), making this module an excellent choice for building high-density, low-latency, scalable data centers.

Product overview

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, which supports more than 83 Terabits per second (Tbps), is the latest extension to the Cisco Nexus 7000 Series modular switches. The Cisco Nexus 7700 platform switches are operationally consistent with the existing Cisco Nexus 7000 Series switches and have a similar system architecture. The Cisco Nexus 7700 Series switches are designed using the same Application-Specific Integrated Circuit (ASIC) technology and run on the same proven NX-OS releases as the Cisco Nexus 7000 switches. Table 1 summarizes the 40GE port density of the switches in this platform.

The Cisco Nexus 7700 M3-Series 24-Port module (Figure 1) is a high-performance, high-density 40 Gigabit Ethernet module designed for the Cisco Nexus 7700 platform. It delivers up to 384 wire-rate 40 Gigabit Ethernet ports in a single Cisco Nexus 7700 18-Slot Switch chassis. 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 sixteen 24-port 40 Gigabit Ethernet M3-Series modules can deliver up to 23 bpps and 30.7 Tbps of switching performance.

The Cisco Nexus 7700 M3-Series 24-Port module is based on the Cisco Nexus M3-Series Switch-on-a-Chip (SoC) ASIC. The M3-Series SoC is an innovative ASIC designed by Cisco that provides a power-efficient, flexible, high- performance packet engine, making it an excellent choice for building I/O modules that power the network infrastructure for public and private cloud environments.

Features and benefits

The Cisco Nexus 7700 M3-Series modules are powered by the proven and widely deployed Cisco NX-OS Software. The Cisco Nexus 7700 M3-Series modules integrate a broad set of data center switching technologies, including both industry standards and Cisco’s own innovations such as these:

     GPRS Tunneling Protocol (GTP) Hashing: This feature leverages the advanced packet parsing capabilities of the M3 modules to provide enhanced port channel and ECMP load balancing for GTP packets.

     Virtual Extensible LAN (VXLAN): VXLAN enables organizations to build highly scalable virtual overlay networks for virtualized environments. It also provides the architectural flexibility and agility required to scale cloud deployments with repeatable pods in different Layer 2 domains and to migrate virtual machines between servers across Layer 3 networks.

     Advanced Data Center Interconnect (DCI) protocols: Advanced protocols such as Cisco Overlay Transport Virtualization (OTV), Locator/ID Separation Protocol (LISP), Multiprotocol Label Switching (MPLS), and Virtual Private LAN Service (VPLS) offer customers a broad choice of technologies to transparently interconnect their data centers and to extend applications across geographically dispersed data center sites.

     Virtual Device Context (VDC): This feature enables the virtualization of a single physical device as multiple logical devices. Each provisioned logical device is configured and managed as if it were a separate physical device.

     Exceptional integrated hardware security capabilities:

     MAC Security (MACsec) at wire rate with 128- and 256-bit encryption on all ports, supporting both key agreement protocols (Security Association Protocol [SAP] and MACsec Key Agreement [MKA]) in hardware

     Cisco TrustSec® technology and Access Control List (ACL) processing for Security-Group Tags (SGTs) on all ports

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

     ACL counters and logging capability to provide deeper packet visibility

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

     Onboard Fabric Services Accelerator (FSA): The accelerator provides higher performance and greater scalability for distributed fabric services such as Bidirectional Forwarding Detection (BFD) and Cisco NetFlow.

     Cisco FabricPath: This technology enables organizations to build resilient, flexible, and massively scalable Layer 2 networks. FabricPath provides investment protection by allowing existing spanning-tree-based deployments to be connected to a FabricPath network.

     Cisco Nexus 2000 Series Fabric Extenders: The Cisco Nexus 7700 M3-Series modules can be used with the Cisco Nexus 2000 Series Fabric Extenders. These fabric extenders are designed to simplify data center architecture and operations by dramatically reducing the number of points of management.

     Port breakout capability: The breakout support for Cisco Nexus 7700 M3-Series 24-Port 40 Gigabit Ethernet Module was introduced in Cisco NX-OS Release 8.0(1). This feature allows up to 23 of the 24 physical 40 Gigabit Ethernet ports on the module to be split into 4 logical and independent 10 Gigabit Ethernet ports. Any port that is not configured for breakout remains available for establishing 40 Gigabit Ethernet links. The capability to configure the breakout mode on each port independently of any other port without the need to reload the module enhances operational simplicity. Copper or fiber breakout assemblies are required to enable the physical separation of 10 Gigabit Ethernet channels.

This broad set of foundational and advanced features available on the Cisco Nexus 7700 M3-Series 24-Port module provides flexible deployment options and investment protection for organizations that are consolidating their data centers and migrating to high-density 40 Gigabit Ethernet networks.

Wire-rate 256-bit AES Encryption

The Cisco Nexus 7700 M3-Series 24-Port module supports wire-rate 256-bit Advanced Encryption Standard (AES) MACsec encryption on all ports at all speeds. This encryption can be used to secure:

     Data center uplinks to campus or MPLS cores

     Data center interconnect links when using OTV, virtual Port Channel (vPC), direct links, etc.

     vPC and FabricPath links within a data center

High-performance fabric services accelerator

The Cisco Nexus 7700 M3-Series 24-Port module has an onboard high-performance coprocessor: a fabric services accelerator. The FSA is directly connected to the M3-Series SoC with high-speed links. This approach enables the module to provide higher performance and greater scalability for distributed fabric services such as BFD and NetFlow.
