特性和优势
Cisco Nexus 7000 M3 系列模块由经过验证且广泛部署的 NX-OS 操作系统提供支持。这些模块集成了广泛的数据中心交换技术，包括行业标准和 Cisco 自己的创新，例如：
● 通用分组无线服务 （GPRS） 隧道协议 （GTP） 散列：此功能使用 M3 系列模块的高级数据包解析功能，为 GTP 数据包提供增强的端口通道和等价多路径 （ECMP） 负载平衡。
● 虚拟可扩展 LAN （VXLAN）：VXLAN 使组织能够为虚拟化环境构建高度可扩展的虚拟叠加网络。它还提供了所需的架构灵活性和敏捷性，以便在不同的第 2 层域中使用可重复的 Pod 扩展云部署，以及跨第 3 层网络在服务器之间迁移虚拟机。
● 高级数据中心互连 （DCI） 协议：思科覆盖传输虚拟化 （OTV）、定位器/ID 分离协议 （LISP）、多协议标签交换 （MPLS） 和虚拟专用局域网服务 （VPLS） 等高级协议为客户提供了广泛的技术选择，以透明方式互连其数据中心，并在地理位置分散的数据中心站点之间扩展应用程序。
● 虚拟设备上下文 （VDC）：此功能支持将单个物理设备虚拟化为多个逻辑设备。每个预置的逻辑设备都像单独的物理设备一样进行配置和管理。
● 卓越的集成硬件安全功能：
◦线速 MAC 安全 （MACsec），所有端口均采用 128 位和 256 位加密，在硬件中支持密钥协议（安全关联协议 [SAP] 和 MACsec 密钥协议 [MKA]）
◦所有端口上安全组标记 （SGT） 的思科 TrustSec® 技术和访问控制列表 （ACL） 处理
◦控制平面策略 （CoPP），可保护 Supervisor CPU 免受过多流量的影响
◦ACL 计数器和日志记录功能，可提供更深入的数据包可见性
◦IPv4 和 IPv6 流量的第 2 层到第 4 层 ACL
● 板载交换矩阵服务加速器 （FSA）：该加速器为双向转发检测 （BFD） 和 Cisco NetFlow 等分布式交换矩阵服务提供更高的性能和更大的可扩展性。
● Cisco FabricPath：这项技术使组织能够构建弹性、灵活且可大规模扩展的第 2 层网络。FabricPath 允许将现有的基于生成树的部署连接到 FabricPath 网络，从而提供投资保护。
● Cisco Nexus 2000 系列交换矩阵扩展器：Cisco Nexus 7000 M3 系列模块可与 Cisco Nexus 2000 系列交换矩阵扩展器配合使用。这些交换矩阵扩展器旨在通过显著减少管理点的数量来简化数据中心架构和运营。

256 位 AES 加密
Cisco Nexus 7000 M3 系列 24 端口 40 Gb 以太网模块支持在所有端口上以任何速度进行 256 位高级加密标准 （AES） MACsec 加密。此加密可用于保护：
● 数据中心上行链路到园区或 MPLS 核心
● 使用 OTV、虚拟端口通道 （vPC）、直接链路等时的 DCI 链路。
● 数据中心内的 vPC 和 FabricPath 链路
高性能 Fabric Services Accelerator
Cisco Nexus 7000 M3 系列 24 端口 40 Gb 以太网模块具有板载高性能协处理器：交换矩阵服务加速器。FSA 通过高速链路直接连接到 M3 系列片上交换机 （SoC）。这种方法使模块能够为 BFD 和 NetFlow 等分布式结构服务提供更高的性能和更大的可扩展性。
Characteristics and advantages
The Cisco Nexus 7000 M3 series modules are powered by the proven and widely deployed NX-OS operating system. These modules integrate a wide range of data center switching technologies, including industry standards and Cisco's own innovations, such as:
General Packet Radio Service (GPRS) Tunneling Protocol (GTP) hashing: This feature uses the advanced packet resolution capabilities of the M3 series modules to provide enhanced port channel and equivalent multipath (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 needed to scale cloud deployments with repeatable Pods across different Layer 2 domains, as well as to migrate virtual machines between servers across Layer 3 networks.
Advanced Data Center Interconnect (DCI) protocol: Cisco covers advanced protocols such as Transport Virtualization (OTV), Locator /ID Separation Protocol (LISP), Multiprotocol Label Switching (MPLS), and Virtual Private Area Network Services (VPLS) to provide customers with a wide range of technology options to transparently interconnect their data centers. And scale applications across geographically dispersed data center sites.
Virtual Device Context (VDC) : This feature allows you to virtualize a single physical device into multiple logical devices. Each preset logical device is configured and managed like a separate physical device.
● Excellent integrated hardware security features:
◦ Line Speed MAC Security (MACsec), 128-bit and 256-bit encryption on all ports, key protocols supported in hardware (Security Association Protocol [SAP] and MACsec Key Protocol [MKA])
◦ Cisco TrustSec® technology and access control List (ACL) processing on all ports for Security group marking (SGT)
◦ The Control Plane Policy (CoPP) protects the Supervisor CPU from excessive traffic
◦ACL counters and logging capabilities provide deeper packet visibility
◦ Layer 2 to Layer 4 ACLs for IPv4 and IPv6 traffic
On-board Exchange Matrix Service Accelerator (FSA) : This accelerator provides higher performance and scalability for distributed exchange matrix 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 the FabricPath network.
Cisco Nexus 2000 Series Switch Matrix expander: The Cisco Nexus 7000 M3 series module can be used with the Cisco Nexus 2000 Series switch Matrix expander. These exchange matrix extenders are designed to simplify data center architecture and operations by significantly reducing the number of management points.
The Cisco Nexus 7000 M3 Series 24-port 40Gb Ethernet module provides this broad set of basic and advanced features, providing flexible deployment options and investment protection for organizations that are consolidating their data centers and migrating to high-density 40Gb Ethernet.
256 bit AES encryption
The Cisco Nexus 7000 M3 Series 24-port 40 Gb Ethernet module supports 256-bit Advanced Encryption Standard (AES) MACsec encryption at any speed on all ports. This encryption can be used to protect:
● Data center uplink to campus or MPLS core
● DCI link when using OTV, Virtual Port Channel (vPC), direct link, etc.
● vPC and FabricPath links within the data center
High-performance Fabric Services Accelerator
The Cisco Nexus 7000 M3 Series 24-port 40 Gb Ethernet module features an onboard high-performance coprocessor: the Switch Matrix Service Accelerator. The FSA connects directly to the M3 Series on-chip switch (SoC) via a high-speed link. This approach enables modules to provide higher performance and scalability for distributed structured services such as BFD and NetFlow.
