The Catalyst 8500 Edge Platforms feature the all-new third-generation Cisco Quantum Flow Processor (QFP), the Catalyst 8500 Series Edge Platforms are built for services from the ground up. The Catalyst 8500L Edge Platform features an x86 based platform architecture that is purpose built to continue delivering the same experience as an ASR1000 platform. The Catalyst 8500 Series Edge Platforms are compact 1RU or 3U (Catalyst C8500-20X6C) devices with flexible interface options, including 1GE, 10GE, 40GE, and 100GE ports. Powered by Cisco IOS XE, fully programmable software architecture, and API support, these platforms can facilitate automation at scale to achieve zero-touch IT capability while migrating workloads to the cloud.Product overviewCatalyst 8500 Edge Platform Product highlightsTable 1.Catalyst 8500 Edge Platform Product highlightsTable 2.Catalyst 8500L Edge Platform Product highlightsTable 3 provides details on each platform’s configurations and port density.

Cisco Catalyst 8000 Series Edge Plat forms can dynamically route traffic across the “best” link based on 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 you need as your branches conduct greater volumes of mission-critical business with both on-premises and cloud controllers.Application optimizationEnsure that SD-WAN networks meet Service-Level Agreements (SLAs) and maintain strong performance, even if network problems occur. With multi-cloud access, you can accelerate your SaaS applications with a simple template push from the SD-WAN controller.Multi-layer securityYou can now move your traditional and complex WAN networks to a more agile software-defined WAN with integrated security. The Cisco Catalyst 8500 Series Edge Platforms feature on-premises and cloud-based security options.Application visibilityApplications and users are more distributed than ever, and the internet has effectively become the new enterprise WAN. As organizations continue to embrace internet, cloud, and SaaS, network and IT teams are challenged to deliver consistent and reliable connectivity and application performance over networks and services they don’t own or directly control.The Catalyst 8500 Series Edge Platforms are integrated with Cisco ThousandEyes internet and cloud intelligence. IT managers now have expanded visibility, including hop-by-hop analytics, into network underlay, proactive monitoring of SD-WAN overlay, and performance measurement of SaaS applications. This granular visibility ultimately lowers the Mean Time to Identification of Issues (MTTI) and accelerates resolution time. Cloud-native agility with programmable software architectureCisco continues to offer a feature-rich traditional IOS XE routing stack on the Cisco Catalyst 8000 Series Edge Platforms. IP Routing, IPSec, Quality of Service (QoS), firewall, Network Address Translation (NAT), Network-Based Application Recognition (NBAR), Flexible NetFlow (FNF), and many other features are part of Cisco IOS XE, a fully programmable software architecture with API support and a wide variety of protocols and configurations. With an integrated software image and a single binary file, you can now choose between Cisco IOS XE SD-WAN and Cisco IOS XE. And easily move from one to the other when you choose to do so.5G-readyThe Cisco Catalyst 8500 Series Edge Platforms are built for future 5G networks. These platforms support external cellular gateway modules with LTE/5G capability for improved throughputs and latency.Compact form factorThe Cisco Catalyst 8500 Series Edge platforms feature compact 1RU and 3RU platforms with rich interface options, including 1G, 10G, 40G, and 100G ports. Featuring the highly efficient third-generation QFP, the Cisco Catalyst 8500 Series Edge Platforms are built without compromising on performance and ports.

CISCO路由器版本升级说明在桂林地区114工程中，局方在县局联网将要完工时要求我们在网络系统增加IPX协议，以备97工程的NOVELL服务器联网。
当时7507路由器软件带IPX协议，但县局2501路由器不带IPX协议，CISCO 路由器软件放在FLASH MEMERY 芯片里，不同的软件件版本带不同的协议，价钱也不一样，为了赶时间和免除商务上的麻烦，我们通过INTERNET与CICSO公司联系，借邮电局的面子，免费取得TFTP SERVER 软件和具有TCP/IP，IPX协议的IOS 软件，下面是CISCO路由器软件升级的过程说明。
1.在interne上的CISCO 站点下载software&support/software centes/other software/tftp server for windows 95/TFTPSRVR.ZIP 文件，此文件用UNZIP 打开后包含四个文件:TFTPSRV.EXE, TFTPSERV.DLL, MFC42.DLL , MSVCRT.DLL,将三个DLL文件拷到WIN95 C:\WINDOWS\SYSTEM目录下.2.通过CISCO公司在internet上下载所需IOS BIN文件（经CISCO北京办事处授权，取得密码，才能下载IOS软件）3.在WIN95上运行TFTPSRV.EXE,并在option 选项中指定BIN 文件路径4.在微机上通过仿真终端运行COPY TFTP FLASH 命令出现Address or name of remote host [255.255.255.255]?时输入相应运行TFTPSRV.EXE微机的IP地址.如168.68.100.100。
Source file name?要求输入TFTPSRV 所指定目录IOS BIN 文件,如gs-in-l_110-19(3).bin Destination file name?要求输入加载到FLASH MEMERY 的IOS 文件名,可以与Source file name 一至如[igs-in-l_110-19(3).bin]?遇到其他他选项,都按Y或回车, 路由器就开始清除FLASH MEMERY的IOS文件,然后通过TFTP SERVER把新的IOS 文件COPY 到FLASH MEMERY里, 软件更换换完后出现路由器名> ,IOS软件更换不会改变原路由器的设置,如名称,密码,IP地址等都与原设置一样.5有时软件更换后,路由器启动时不是取FLASH MEMERY 的IOS 软件而是取BOOT ROOM 的软件,此时显示路由器名(boot)>.用sh ver 和sh flash 可看到两个版本不一致(FLASH MEMERY理的软件才是更换后的软件)。

利用PacketTracer5.0练习思科IOS操作命令很不错的。
要配置好Cisco交换必需要熟悉IOS命令及相关的知识。

CISCO路由器也包含硬件和软件两部分。
. 物理端口介绍CISCO 2500系列包含以下几种端口：高速同步串口，最大支持的E1速率。
通过软件配置，该种端口可以连接DDN，帧中继（Frame Relay），，PSTN（模拟电话线路）。
注意：如果用该同步端口连接电话线路，要求Moden必须支持同步/异步串口，该种端口可以用软件设置为同步工作方式。
在同步工作方式下，最大支持128K，异步方式下，最大支持。
AUI端口，即粗缆口。
一般需要外接转换器（AUI-RJ45），连接10Base-T以太网络。
ISDN端口，可以连接ISDN网络(2B+D)。
AUX端口，该端口为异步端口，最大支持３８４００的速率，主要用于远程配置或拔号备份。
ciscoap配置手册详解你还在为不知道ciscoap配置手册详解而烦恼么?接下来是小编为大家收集的ciscoap配置手册详解教程，希望能帮到大家。
ciscoap配置手册详解的方法cisco ap配置手册Cisco AP的配置方法主要有控制台端口登录、远程登录(如Telnet/SSH等)、Web浏览器等，后两种方式均需要获取或设置一个IP方可登录。
一般情况下，AP设置IP地址的方法有按默认方式获取，配置DHCP方式获取，使用IPSU(IP Setup Utility)，使用控制台端口等。
实际上对Cisco AP来讲，配置的最简单的方法就是使用Web浏览器方式即GUI方式。
Cisco AP有两种基本GUI界面，一种是支持IOS GUI，如Arionet 1100系列;一种是VxWorks GUI，如Arionet 350的AP和网桥;而Arionet 1200系列可以支持这两种GUI界面。
如下图Cisco Aironet 1100系列AP GUI配置界面：除了GUI和远程登录方式外，CLI(命令行)也是Cisco AP经常使用的配置方式。
GUI的配置方法比较简单，因篇幅所限，不再作介绍。
下面我们在CLI(命令行)模式下对Cisco AP进行配置。
Cisco AP的IOS的CLI(命令行)的配置模式有：用户模式、特权模式、全局模式、接口模式、线路模式等等，它的命令提示符、基本配置命令与基于Cisco IOS系统的路由器和交换机CLI的模式也基本相同，如果您对各种模式还不熟悉，请您参照路由器和交换机的基本模式配置章节。
1、配置主机名注意：hostname name命令中的name名称必须符合ARPANET 主机名的规则，最多为63个字符，并且必须以一个字母开头，结尾必须是一个字母或数字，中间只能是字母、数字或连接符。
2、配置IP地址为了实现对设备的远程管理，我们通常需要对设备配置管理地址，对于AP来说，我们可以通过配置AP的BVI地址来实现。
