CISCO路由器初始配置手册

CISCO路由器初始配置手册

很多初学路由器知识的网友对路由器的初始配置可能感到很陌生,本人在初学时也很困惑,因为一下出来很多提问不知如何是好,下面将最近刚调试的一台CISCO3640的初始配置整理出来与各位网友交流,如有疏漏之处,还请大家指正。

1.用CISCO随机带CONSOLE线,一端连在CISCO路由器的CONSOLE口,一端连在计算机的COM口。

2.打开电脑,启动超级终端.为您的连接取个名字,比如CISCO_SETUP,下一步选定连接时用COM1,下一步选定第秒位数9600,数据位8,奇偶校验无,停止位1,数据流控制无.最后选确定。

3.打开路由器电源,这时超级终端将出现以下画面:

--- System Configuration Dialog ---

Would you like to enter the initial configuration dialog? [yes/no]: y您是否进入初始化配置对话,选YAt any point you may enter 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 connectivityfor management of the system, extended setup will ask youto configure each interface on the system

Would you like to enter basic management setup? [yes/no]: n您是否进入基本配置安装,选NFirst, would you like to see the current interface summary? [yes]: y首先,您是否看一下当前端口状态Any interface listed with OK? value "NO" does not have a valid configuration

Enter host name [Router]:RouterA输入路由器的名字The enable secret is a password used to protect access toprivileged EXEC and configuration modes. This password, afterentered, becomes encrypted in the configuration.Enter enable secret: aaa输入密文The enable password is used when you do not specify anenable secret password, with some older software versions, andsome boot images.Enter enable password: bbb输入密码(不能和密文相同) The virtual terminal password is used to protectaccess to the router over a network interface.Enter virtual terminal password: ccc输入虚拟终端的密码(以备远程登录)Configure SNMP Network Management?

[no]: y选用全双工模式?选YConfigure IP on this interface? [yes]: y在这个接口上配置IP吗?选YIP address for this interface: 192.168.0.1配置该接口的IP地址(在此地址为192.168.0.1Subnet mask for this interface [255.255.255.0] :配置该接口的子网掩码.(默认的是255.255.255.0,可以手工输入修改)Class C network is 192.168.0.0, 24 subnet bits; mask is /24

Do you want to configure Serial0/0 interface? [yes]: y您想配置serial0/0接口吗?选YSome supported encapsulations are ppp/hdlc/frame-relay/lapb/x25/atm-dxi/smdsChoose encapsulation type [hdlc]: 选择封装方式(默认的封装方式是HDLC,您可根据与您的路由器相连选用的封装类型来决

定用什么样的封装类型No serial cable seen. Choose mode from (dce/dte) [dte]:(因为没有连串口线所以会让您选择设备类型)Configure IP on this interface? [yes]: y (在接口上配置IP)Configure IP unnumbered on this interface?
