Data SheetCisco 4000 Family Integrated Services RouterCisco® 4000 Family Integrated Services Routers (ISRs) form an intelligent WAN platform that delivers the performance, security, and convergence capabilities that today’s branch offices need.Product OverviewThe Cisco 4000 Family Integrated Services Router (ISR) revolutionizes WAN communications in the enterprise branch. With new levels of built-in intelligent network capabilities and convergence, it specifically addresses the growing need for application-aware networking in distributed enterprise sites. These locations tend to have lean IT resources. But they often also have a growing need for direct communication with both private data centers and public clouds across diverse links, including Multiprotocol Label Switching (MPLS) VPNs and the Internet.The Cisco 4000 Family contains five platforms: the 4451-X, 4431, 4351, 4331, and 4321 ISRs.Figure 1. Cisco 4000 Series Integrated Services RoutersFeatures and BenefitsCisco 4000 Family ISRs provide you with Cisco® Intelligent WAN (IWAN) software features and a converged branch infrastructure. Along with superior throughput, these capabilities form the building blocks of next-generation branch-office WAN solutions.Cisco Intelligent WAN (IWAN)Cisco IWAN is a set of intelligent software services that allow you to reliably and securely connect users, devices, and branch office locations across a diverse set of WAN transport links. IWAN-enabled routers like the ISR 4000 dynamically route traffic across the “best” link based o n up-to-the-minute application and network conditions for great application experiences. You get tight control over application performance, bandwidth usage, data privacy, and availability of your WAN links - control that you need as your branches conduct greater volumes of mission-critical business.Cisco Converged Branch InfrastructureThe Cisco 4000 Series ISRs consolidate many must-have IT functions, including network, compute, and storage resources. The high-performance, integrated routers run multiple concurrent IWAN services, including encryption, traffic management, and WAN optimization, without slowing your data throughput. And you can activate new services on demand through a simple licensing change.Table 1 breaks out many of the features and benefits of the Cisco 4000 Family that create an intelligent WAN and a converged branch infrastructure.Table 1.

Cisco路由器的基本知识及配置介绍第一章Cisco路由器基本知识1.1 CISCO常用路由器的型号、规格Cisco公司的路由器产品大致可分为如下几类：⏹低档路由器：适用小型办公室的cisco 1600系列⏹中档路由器：Cisco 2500、Cisco 2600、Cisco 3600系列⏹高档路由器：Cisco 4000以上系列路由器，电信级产品我们（非电信）一般接触到的产品以中档路由器为主。
16和25系列路由器是固定端口的（16系列有一个广域卡扩展槽），即有多少个广域口、有多少个局域口是固定死的，而象26系列、36系列、4000以上系列路由器，都是模块化的，用户可以任意选购模块或扩展卡，自由组合出所需要的局域及广域口数。
由于路由器通常要接广域线路，所以就涉及到一个选用怎样的广域接口的问题。
常见的接口有V.35、RS-232等接口，在选用路由器时要注意选择相应的产品和线缆。
CISCO的产品是通过线缆来进行端口区分的。
即：通常路由器上的广域接口是一种CISCO的接口（不同型号接口类型有所不同），通过一根电缆，一头接在CISCO路由器上，而另一头的接口形式有的是V.35，有的是RS232。
1.2 路由器常用物理端口介绍局域口：1）AUI口：即粗缆口，一般需要外接转换器（AUI-RJ45），连接10M以太网。
2）RJ45口：有10M和10/100M两种。
广域口：1）高速同步口：最大支持2M速率。
2）同步/异步串口：该端口可以用软件设置为同步或异步工作方式。
在同步工作方式下，最大支持128K，在异步方式下，最大支持115.2K。
3）ISDN口：可以连接ISDN网络（2B+D）。
4)其它……AUX口：该端口为异步口，最大支持38.4K速率，主要用于远程配置或拨号备份。
Console口：主要连接终端或运行终端仿真程序的计算机，在本地配置路由器。
1.3 路由器内存体系结构介绍CISCO路由器的软件部分就是IOS，即网络操作系统，通过IOS，实现丰富的网络功能。

cisco路由器的参数和功能知识Cisco（思科）路由器是一种网络设备，被广泛应用于各种规模的网络环境中。
它具备丰富的参数和功能，为网络管理员提供了高度灵活和强大的配置选项。
本文将介绍Cisco路由器的参数和功能知识。
一、路由器参数知识1. IP地址：IP（Internet Protocol）地址是计算机在网络中唯一标识的地址。
Cisco 路由器支持IPv4和IPv6协议，管理员可以配置IP地址以及子网掩码来正确地划分网络。
2. 网关：网关是连接两个不同网络的设备，通常是路由器。
Cisco 路由器可以作为默认网关，将数据包从本地网络转发到其他网络。
3. 路由表：路由表是路由器存储的一份记录。
其中包含了网络之间的最佳路径，路由器通过查找路由表来决定数据包的转发方向。
4. ARP（Address Resolution Protocol）：ARP是用于解析网络层地址（IP地址）和物理层地址（MAC地址）之间对应关系的协议。
路由器可以维护ARP缓存表，记录IP地址和MAC地址的映射关系。
5. NAT（Network Address Translation）：NAT是一种将私有IP地址转换为公共IP地址的技术，用于解决IP地址短缺问题。
Cisco 路由器支持多种NAT方式，如静态NAT、动态NAT和PAT（Port Address Translation）。
二、路由器功能知识1. 路由：路由器最主要的功能就是进行数据包的路由转发。
路由器可以通过学习路由协议（如OSPF、RIP等）来更新路由表，并根据最佳路径将数据包转发到目标网络。
2. ACL（Access Control List）：ACL是一种基于网络流量的过滤机制，通过对数据包的源、目的IP地址、协议、端口等进行匹配，来决定是否允许或拒绝数据包通过路由器。
3. DHCP（Dynamic Host Configuration Protocol）：DHCP是一种自动分配IP地址的协议，可以通过路由器为网络中的设备提供动态IP地址、DNS服务器地址、网关地址等信息。
Data Sheet Cisco 4000 Series Integrated Services Router Gigabit Ethernet WAN Modules Data SheetProduct OverviewCisco® Gigabit Ethernet WAN Modules bring high-density Small Form-Factor Pluggable (SFP) and copper (RJ-45) 1 Gigabit and 10 Gigabit Ethernet (GE) connectivity to the Cisco 4000 Series Integrated Services Routers (ISRs). Providing maximum flexibility, the modules accelerate applications such as Ethernet WAN access, inter-VLAN routing, and high-speed connectivity to LAN switches and servers.The ports on these modules work as routed Layer 3 ports. Layer 2 switching between local ports on the module or between ports on the module and other ports within the router system is not supported. The port terminates Layer 2 trunks from externally connected switches, and Layer 2 trunk and VLAN information is not switched onto other ports in the system. The host router routes all traffic entering these modules.Cisco Gigabit Ethernet WAN Modules do not support Power over Ethernet (PoE).Cisco offers four types of Ethernet WAN modules:●Cisco 1-Port Gigabit Ethernet WAN Network Interface Module (NIM-1GE-CU-SFP) (Figure 1)●Cisco 2-Port Gigabit Ethernet WAN Network Interface Module (NIM-2GE-CU-SFP) (Figure 1)●Cisco 6-Port High-Density Gigabit Ethernet WAN Service Module (SM-X-6X1G) (Figure 2)●Cisco 4-Port High-Density Gigabit or 1-Port 10 Gigabit Ethernet WAN Service Module (SM-X-4X1G-1X10G)(Figure 3)The Cisco 4-Port Gigabit or 1-Port 10 Gigabit Ethernet WAN Service Module can be operated in two mutually exclusive modes:●4-port Gigabit Ethernet mode●1-port 10 Gigabit Ethernet mode; use of the 10 Gigabit Ethernet port disables the other portsFigure 1. Cisco 1- and 2-Port Gigabit Ethernet WAN Network Interface ModulesFigure 2.Cisco 6-Port High-Density Gigabit Ethernet WAN Service ModuleFigure 3.Cisco 4-Port High-Density Gigabit or 1-Port 10 Gigabit Ethernet WAN Service ModuleModule Feature ComparisonTable 1 compares the software and hardware features at a high level.Table 1.Feature Comparison*Requires Cisco IOS ®XE Software Release 3.16. Auto-switchover and auto-failover are also supported on front-panel Gigabit Ethernet ports on the Cisco 4000 Series ISRs on the dual-phy GE interface ports.**For the classifications of packets on the input queue (to apply quality of service [QoS]), two types of classification methods are supported: based on either IPv4 and IPv6 or standard 802.1Q. These methods are mutually exclusive.The IPv4 and IPv6 classification rules can be enabled on up to three of the external ports. The same rules must apply to both IPv4 and IPv6 addresses. The 802.1Q-based classification is supported on all ports.The Cisco Gigabit Ethernet WAN Modules report the packet and byte statistics at an aggregate level per port. These statistics cannot be generated per VLAN. These measurements include policy drops, oversubscription drops, unicast, broadcast input, and output packet bytes or counts.InstallationYou can install service modules and network modules either before or after mounting the router. The 1- and 2-port NIMs also support the enhanced service module (SM-X) slot with an adaptor card. The Cisco Gigabit Ethernet WAN Modules support hard online insertion and removal (OIR). You can insert them into the router while the router is powered on.For important tips, safety warnings, and other information you need to know before and during installation of the Cisco Gigabit Ethernet WAN Modules, please refer to Installing Cisco Network Modules and Service Modules in Cisco Access Routers.Warning: To comply with the Telcordia GR-1089 Network Equipment Building Standards (NEBS) for electromagnetic compatibility and safety, connect the Gigabit Ethernet ports only to intrabuilding or unexposed wiring or cable. The intrabuilding cable must be shielded and the shield must be grounded at both ends. The intrabuilding port(s) of the equipment or subassembly must not be metallically connected to interfaces that connect to the outside plant (OSP) or its wiring. These interfaces are designed for use as intrabuilding interfaces for only type 2 or type 4 ports as described in Telcordia GR-1089-CORE, and they require isolation from the exposed OSP cabling. The addition of primary protectors is not sufficient protection to connect these interfaces metallically to OSP wiring.Platform, SFP, and Cisco IOS XE Software Release SupportThe Cisco Gigabit Ethernet WAN Modules are generally supported on all Cisco 4000 Series ISRs subject to the availability of an appropriate slot. You may deploy as many modules as the platform slot density allows. For specific details about platform, SFP, and Cisco IOS XE Software support, visit the Ethernet WAN section at:/c/en/us/products/routers/4000-series-integrated-services-routers-isr/relevant-interfaces-and-modules.html.For configuration ins tructions, refer to the “Configuring Ethernet, Fast Ethernet, or Gigabit Ethernet Interfaces” chapter of Configuring LAN Interfaces. The guidelines in this chapter apply to all Cisco modular access routers.For more configuration instructions and other rel ated documents, refer to the “Related Documents and Links” section on page 6 of that document.Note: Use the show diag command to check the hardware information of the Cisco Gigabit Ethernet WAN Service Modules.Module LED IndicatorsThe Cisco Gigabit Ethernet WAN Modules have several EN (Enabled) or L (Link) LEDs located around the SFP and RJ-45 ports. The LEDs indicate that the module has passed its self-test and is available to the router. Tables 2 and 3 list the LED colors and their meanings.Table 2. EN (Enable) and L (Link) LED StatusTable 3. S (Speed) LED StatusDeployment ExamplesCisco Intelligent WANThe Cisco Intelligent WAN (IWAN) solution enables customers to deploy new services faster regardless of transport model, whether it is a private WAN using a Multiprotocol Label Switching (MPLS) offering, a common Internet connection, or hybrid WAN access consisting of both models. The Cisco IWAN solution furthermore allows organizations to realize significant cost benefits from using the common Internet as the underlying WAN infrastructure. Using the Cisco Integrated Services Router with Application Experience (ISR-AX) services, based on application, endpoint, and network conditions, you can dynamically route traffic over multiple WAN connections in order to deliver the best-quality experience.Figure 4 demonstrates the use of the Cisco 1-Port 10 Gigabit Ethernet WAN Service Module as part of the Cisco IWAN solution. At the regional office, the Cisco 6-Port Gigabit Ethernet WAN Service Module aggregates the sub-rate Gigabit Ethernet WAN connections from different Internet service providers (ISPs). The remote branch-office routers connect to either one, or in some cases both, of those ISPs.Figure 4. Cisco 6-Port Gigabit Ethernet Service Module as Part of Cisco IWAN SolutionFiber and Copper Aggregation within Building and IntracampusFigure 5 demonstrates the use of the Cisco 6-Port Gigabit Ethernet WAN Service Module in a campus LAN environment with the mix of copper and fiber cabling options. The Cisco 6-Port Gigabit Ethernet WAN Service Module provides great flexibility, eliminates the need for a separate switch, and increases network reliability.The combination of two service modules plus the 4 onboard ports can support up to 16 routed fiber ports in a single Cisco 4451-X chassis, adding superior scalability to intracampus networking connections.Figure 5. Cisco 6-Port Gigabit Ethernet WAN Service Module for the Campus NetworkAggregation for Mobile Service Provider Picocell or Femtocell Network DeploymentFigure 6 demonstrates the use of the Cisco 4-Port Gigabit or 1-Port 10 Gigabit Ethernet WAN Service Modules in a typical mobile service provider’s (MSP’s) picocell or femtocell deployment. The module provides fiber aggregation to links from multiple intermediate distribution frames (IDFs), again eliminating the need for a separate switch and reducing the number of devices to provision and manage.Figure 6. Cisco 4-Port Gigabit or 1-Port 10 Gigabit Ethernet WAN Service Modules for Aggregation in Picocell and Femtocell DeploymentsFeaturesThe Cisco Gigabit Ethernet WAN Service Modules are based on the technology of the onboard Gigabit Ethernet and SFP ports on the Cisco 4000 Series ISR. Feature support is therefore identical to that of the onboard ports.SpecificationsTables 4 and 5 list the physical and environmental specifications, respectively, of the Cisco Gigabit Ethernet WAN Service Modules.Table 4.

思科Cisco 交换机型号概述思科Cisco 交换机的命名一般是WS开头这个是固定的，再下一个字母有两种一个是C一个是X，C代表固化交换机或者机箱，X代表的是模块。
比如看到WS-C3750-24TS-S这个型号的时候我们应该知道他是CISCO交换机.固化交换机3750系列，24个以太网口，TS表示是以太口+SFP口后面的S表示是标准版的，相应的型号就是E的，属于增强型或者叫企业版。
再如WS-X6748-SFP，WS还是代表交换设备，x表示模块，6表示6000系列，7表示7代产品，48表示48口，SFP 表示端口类型。
Cisco交换机有以下几个系列：1900系列：19242900系列：2924、2924M2950系列：2950-24、2950G-24/48、2950C-24、2950T-24、2950SX-24/48 2960系列：2960-24/48TT-L、296024/48TC-L3500系列：3508G、3524、35483550系列：3550-24-SMI/EMI、3550-48-SMI/EMI、3550-12G/T3560系列：3560-24/48也有带G的3750系列：3750-24/48-TS-S、3750-24/48-TS-E 3750G-24/48-TS-S、3750G-24/48-TS-E 、3750G-12S4000系列：4003、40064500系列：4503、4506、4507R6000系列：6006、60096500系列：6506、6509、65137600系列：7609、7613可扩展性分类Cisco的交换机产品以“Catalyst”为商标，包含1900、2800、2900、3500、4000、5000、5500、6000、8500等十多个系列。
总的来说，这些交换机可以分为两类：一类是固定配置交换机，包括3500及以下的大部分型号，比如1924是24口10M以太交换机，带两个100M上行端口。
产品手册适用于思科 4000 系列 ISR 的模拟语音网络接口模块 (NIM)在思科 4000 系列 ISR 上使用 NIM 支持多种语音应用简介思科® 4000 系列集成多业务路由器 (ISR) 支持使用思科网络接口模块 (NIM) 提高端口密度和模块容量，NIM 是增强版高速广域网接口卡 (EHWIC) 进一步演化的产物。

白皮书Cisco 4000 系列集成服务路由器：其架构有益于分支机构灵活工作分支机构所面临的挑战分支机构面临的挑战-提供全面服务:高清视频 位置服务基于云的服务 移动用户 限制因素:机架空间 预算IT员工日益增加的网络需求和新的流量模式:广域网优化和智能缓存深度包检测流量管理 托管虚拟服务器Cisco 4000 系列集成服务路由器（ISRs ）为分散式组织而设计，这些分散式的组织拥有多个分支机构和远程站点。
目前的分支机构能够通过云、移动和多媒体应用提供各种服务，同时需要跨VPN 和互联网完成与私有数据中心、公共云之间日益频繁的直接交流。
他们也需要压缩其网络硬件的总拥有成本。
Cisco 4000 系列集成服务路由器（ISRs ）使用数量更少，体积更小的设备增加了带宽，还使用广域网流量管理来对付新的应用和使用模式，性能随需应变能力，和服务器整合等问题，从而提高了思科既有的分支机构路由器的性能。
过去，这些分支机构和远程站点为本地或者数据中心托管的应用程序提供静态连接站点。
由于这些分支机构为超过80%的消费者和雇员提供服务，所以为了一个移动办公人员工作以及云应用，组织会为这些全方位服务的分支机构提供动态连接支持。
目前的趋势也正引入一种新的沉浸式应用程序，去促进员工的工作效率以及客户的参与程度。
高清视频,位置服务以及其他数据量大的应用程序使得企业处于不断创新的过程中。
然而，各种资源并未根据需求按照比例增加，所以分支机构需要根据有限条件来发挥最大工作效率，来解决日益增加的网络流量问题。
这些分支机构拥有为数不多的IT员工，其用于放置硬件的机架空间狭小拥挤，而且用于硬件、能源和冷却设备的预算又通常让他们捉襟见肘。
种种限制，对这些分支机构来说，操作数量诸多的设备来完成如路由，安全和广域网优等工作很困难。
移动用户、云服务和多媒体应用给网络提出了更高要求：更高的网络负载和新型流量模式。
分支机构必须通过广域网优化、深度包检测和流量管理技巧来为繁忙的下行及上行流量提供支持。
而且，这些分支机构发现在使用基于云的应用时，通过在互联网上直接发送流量而不是让流量通过数据中心再出来的方式，他们能因此节省相当的费用。
为确保在广域网断电的情况下保护机构的运作，如打印和发送邮件等，分支机构也可能需要运行虚拟机。
Cisco 4000 系列集成服务路由器ISRs 使得分支机构通过使用单一设备就可处理增加的带宽，无需另外安装安全及优化设备，这样就帮助机构控制了成本。
数量较少的IT 员工就可以管理这一平台。
平台可以同时运行智能广域网（IWAN ）服务，这包括安全、应用优化、AVC 和智能路径选择。
高性价比的性能也扩展到对设备的实体设计上：Cisco 4000 系列ISRs 比起上一代产品，其设备外形更为小巧；同时还安装了行业领先的传感器，这可以帮助保证风扇以最佳速度旋转，因此也能减少办公区的噪音污染。
向您介绍来自思科的新型集成服务路由器架构Cisco 4000 系列集成服务路由器ISRs 以有20年历史的分支机构路由器为基础而生成，根据现代分支机构运作需求增加了服务，提高了运作功率，使得企业能够：-快速开办新的远程机构或者轻松地增加附加服务单个路由器就可支持整个机构运作自动重复任务、组织安全和应用服务功能给IT部门争取更多时间用于创新新架构的关键特点Cisco 4000 系列集成服务路由器ISRs 具有几个重要的特点，这使得它成为目前分支机构的完美选择：成本控制性能:这一新的架构在保留思科既有分支机构路由器所有服务的基础上，还能进一步处理现代分支机构面临的问题。
它带来了虚拟化的网络，这样IT 部门可以更快推广服务以及根据需求重新对资源进行调整。
而且这一架构也为本地应用的生存、数据备份和本地分析处理提供额外的计算能力。
Cisco 4000 系列集成服务路由器ISRs 的新式架构在单个聚合平台上将数据传输速度能提高到2 Gbps ，比思科既有的ISRs 速度快4到10倍。
Cisco 4000 系列集成服务路由器ISRs 的广域网和应用优化服务不仅包含了思科的应用感知和控制功能l (AVC)，这使得IT 能够对系统进行容量规划；而且还包含了思科性能路由版本3（PfR v3），它使得路由器能够在当前网络条件下通过最佳连接来传输流量。
这一架构不但允许分支机构通过单个设备来运行网络，也可以使用这一单一设备来聚合网络、计算，以及在同一平台存储资源。
虚拟技术，应用于Cisco 4000 系列内以及通过附加的数据中心级别服务器模块，使得融合能力新步入了一个新高度。
需求性能（按需付费）：无需购买新的路由器设备，分支机构就可将带宽升级到更高的水平。
存在于Cisco 4000 系列集成服务路由器ISRs 中的每个模型都提供附加的性能和服务，这些性能和服务你可以在有许可的情况下远程激活。
举例说，Cisco 4351可以为分支机构实现200 Mbps 的基准性能。
但是当一个新的应用部署增加了对带宽的需要，你无需其他附加硬件就可以对其升级（Cisco 4351最高带宽为400 Mbps ），升级费用是购买新路由器的一小部分而已。
按需服务：服务容器使得虚拟机可以在Cisco 4000 系列集成服务路由器ISRs 中运行。
分支机构目前正在运行中的基本的分支机构服务，比如广域网优化和能源管理等，可以在路由器上本机运行。
因此，分支机构可以合并服务器和装置，减少硬件占用和能源消耗。
可扩展服务：Cisco 4000 系列路由器支持多个思科统一计算系统(Cisco UCS®) E系列刀片服务器，这些刀片服务器相当于一个完整大小的服务器。
这些刀片利用路由器的电源和机箱，但是却脱离路由器而被单独管理；重置刀片不需要重置路由器，而且网络团队人员不需要将他们的密码给服务器团队。
这样的架构设计带给IT部门一个独立的数据中心级服务器所有的全部好处，而无需维护另外的设备。
而且，无需单独的服务器虚拟机许可，故障排除仅涉及一个联系人而不是多个供应商，这样带来更佳运行时间和可靠性。
还有一个额外的好处，通过Cisco SMARTnet®服务而实现的硬件支持成本被捆绑进路由器支持费用里。
托管在ISR里的任何思科UCS E-系列服务器都不会被另外收费。
这是有益的，因为当在处理服务器中潜在的硬盘故障时，那些支持费就可以说得通了。
Cisco 4000系列：技术亮点和比较Cisco 4000系列使用新的基于Linux的操作系统，Cisco IOS® XE Software，它保留了上一代路由器所使用的思科IOS 操作系统的用户界面设计，但是可以使用多核CPU。
此设置有利于数据和控制两个平面分离，在服务平面使用专用的CPU。
因为服务平面与数据和控制平面是分开来的，路由器可以在单个平台上处理更多的服务，允许机构去合并设备。
具有可存活远程站点电话技术(SRST)或者路由技术的思科统一边界要素(Cisco UBE)的解决方案，目前可以在单个ISR 上被轻松而快速地部署。
而且，对很多服务来说，比如说Cisco UBE 解决方案，不需增加端口成本，所以其可扩展性显得尤为强大。
在绝大多数典型的分支机构部署中，性能仍旧表现稳定。
这样就给分支机构带来了像应用型专用集成电路（ASIC）一样的性能表现和高度可靠的平台。
服务容器提供了专门的虚拟化计算资源，在每个服务过程中，都为包括CPU、磁盘存储和内存提供资源。
在应用和服务平面，行业标准的管理程序展现了底层基础架构。
与紧密耦合的服务类型相比，这种方案性能更优，可以实现零占用空间部署，采用隔离故障方法来保证系统安全，而且可以独立于路由器软件来自由地升级网络服务。
思科Cisco 4400和4300系列思科Cisco 4400和4300系列ISRs 在用户界面设计上十分相似。
对绝大多数用户来说，两者最大的不同就是Cisco 4400系列支持双电源，而4300系列不支持；这点区别使得Cisco 4451 和4431成为那些不能容忍任何停机时间的组织的优先选择。
4400系列路由器在控制平面和数据平面之间有个物理分离，而且都使用专用的处理器插槽。
Cisco 4300系列使用一个处理器插槽，多CPU内核分配到控制平面、数据平面和服务平面上。
这点大多数用户都不会注意到。

所有功能都完全一致，给客户带来相同的体验和产品特点。
Cisco 4451 是现有的Cisco 3925E 和3945E 路由器的推荐接替版本。
它具有1G 的性能，如果使用于一个2RU 的服务器设备，具备3个网络接口模块(NIM)槽和2个强化服务模块（SM-X ）槽，可以升级到2G 性能。
它还包括一个对冗余电源的选择功能。
