操作和配置Cisco IOS设备启动路由器

1、启动路由器,目标,通过完成这一节的学习，你将能够： 启动一台路由器并识别正常的启动顺序 使用Cisco IOS软件的命令行接口(CLI) 使用命令行接口(CLI)在线帮助工具,Cisco路由器的初始启动,系统启动时例行程序初始化路由器软件 如果需要，路由器的启动顺序是可以选择的,路由器启动时的输出,没有配置文件和有配置文件的路由器启动对比,Setup：初始配置对话框,Router#setup - System Configuration Dialog - Continue with configuration dialog? yes/no: yes At any point you may e

2、nter a question mark ? for help. Use ctrl-c to abort configuration dialog at any prompt. Default settings are in square brackets . Basic management setup configures only enough connectivity for management of the system, extended setup will ask you to configure each interface on the system Would you

3、like to enter basic management setup? yes/no: no,浏览接口摘要,First, would you like to see the current interface summary? yes: InterfaceIP-AddressOK?Method Status Protocol BRI0unassignedYES unset administratively down down BRI0:1unassignedYES unset administratively down down BRI0:2unassignedYES unset admi

4、nistratively down down Ethernet0unassignedYES unset administratively down down Serial0unassignedYES unset administratively down down,在启动过程中找到的接口,初始化设置全局参数,Configuring global parameters: Enter host name Router:ccna_lab The enable secret is a password used to protect access to privileged EXEC and conf

5、iguration modes. This password, after entered, becomes encrypted in the configuration. Enter enable secret: ccna The enable password is used when you do not specify an enable secret password, with some older software versions, and some boot images. Enter enable password: alading The virtual terminal

6、 password is used to protect access to the router over a network interface. Enter virtual terminal password: cisco Configure SNMP Network Management? no:,初始化协议配置,Configure LAT? yes: no Configure AppleTalk? no: Configure DECnet? no: Configure IP? yes: Configure IGRP routing? yes: no Configure RIP rou

7、ting? no: Configure CLNS? no: Configure IPX? no: Configure Vines? no: Configure XNS? no: Configure Apollo? no:,BRI interface needs isdn switch-type to be configured Valid switch types are : 0 none.Only if you dont want to configure BRI. 1 basic-1tr6.1TR6 switch type for Germany 2 basic-5ess.AT mask

8、is /24 Do you want to configure Serial0 interface? no:,设置接口参数,The following configuration command script was created: hostname Router enable secret 5 $1$/CCk$4r7zDwDNeqkxFO.kJxC3G0 enable password sanfran line vty 0 4 password sanjose no snmp-server ! no appletalk routing no decnet routing ip routin

9、g no clns routing no ipx routing no vines routing no xns routing no apollo routing isdn switch-type basic-5ess,interface BRI0 shutdown no ip address ! interface Ethernet0 no shutdown ip address 10.1.1.31 255.255.255.0 no mop enabled ! interface Serial0 shutdown no ip address end 0 Go to the IOS comm

10、and prompt without saving this config. 1 Return back to the setup without saving this config. 2 Save this configuration to nvram and exit. Enter your selection 2:,设置配置脚本的确认和应用,登录路由器,路由器用户模式命令列表,wg_ro_c? Exec commands: access-enable Create a temporary Access-List entry atmsig Execute Atm Signalling C

11、ommands cd Change current device clear Reset functions connect Open a terminal connection dir List files on given device disable Turn off privileged commands disconnect Disconnect an existing network connection enable Turn on privileged commands exit Exit from the EXEC help Description of the intera

12、ctive help system lat Open a lat connection lock Lock the terminal login Log in as a particular user logout Exit from the EXEC- More -,只要所输命令串在全部命令中是唯一的，可以将一个命令尽可能地简写。,路由器特权模式命令列表,只要所输命令串在全部命令中是唯一的，紧接着按tab键就可以完整地输入一个命令。,上下文关联帮助,控制台错误消息,标识错误输入的路由器命令，以便于修改或纠正它们。,允许重新调出以前运行过的命令，用来再次运行、查看或修改。,命令历史记录缓冲区,提供命令列表和与特定命令相关联的提示信息。,路由器命令行帮助功能,路由器上下文关联帮助,路由器上下文关联帮助（续）,RouterShape the future of internetworking by creating unpreced,Shape the future of internetwo
