IOS设备,本章目标(续),在不同的用户界面下应用各种帮助和命令行编辑功能,查看并确认并于各网络设备的基本信息,Cisco,路由器的硬件构成,1.中央处理器(,CPU),2.内存,(1)只读内存(,ROM),(2),随机访问内存(,RAM),(3),闪存(,FLASH),(4),非易失性内存(,NVRAM),3.,接口(,Interface),Cisco IOS,软件提供多种网络服务，支持各种网络应用,.,Cisco,互连网操作系统,(IOS),软件,网络设备的配置,基于以下各方面来配置设备,:,所需功能的网络策略,与协议关联的地址和相关参数,管理方面的需要,交换机将出厂缺省设置作为初始配置,如果路由器中没有配置文件，会提示进入初始化设置过程,硬件自检,定位并加载,Cisco IOS,映象文件,定位并运行配置文件,Cisco,设备的简单启动过程,可以通过多种途径来配置,配置直接在设备的内存中生效,控制端口,Aux,端口,端口,PC or Unix,服务器,Web,或网络管,理服务器,虚拟终端,多种途径的配置,Telnet,TFTP,提供命令行界面,在不同的网络设备上运行时有差别,在命令模式下可以键入或粘贴命令,键入命令后回车，设备即解析和执行所键入的命令,两个主要命令模式是用户模式和特权模式,不同的命令模式有不同的提示符,Cisco,IOS,Cisco IOS,用户界面的基本特性,用户模式,对交换机和路由器的有限操作,命令提示符为,主机名,主要有两个命令模式提供命令键入.,模式一:,Cisco IOS,的主要命令模式,特权,(,或,enabled),模式,对交换机和路由器更深入的操作,有配置和监视权力,是进入其它配置模式的前提,命令提示符为,主机名,#,模式二,(,也是最常用的模式):,Cisco
