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Y
At 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 connectivity
for management of the system, extended setup will ask you
to 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N
First, 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

Interface IP-Address OK? Method Status Protocol
FastEthernet0/0unassigned NO unset up down
Serial0/0 unassigned NO unset down down
FastEthernet0/1unassigned NO unset up down

Configuring global parameters:

Enter host name [Router]:RouterA
输入路由器的名字
The enable secret is a password used to protect access to
privileged EXEC and configuration modes. This password, after
entered, becomes encrypted in the configuration.
Enter enable secret: aaa
输入密文
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: bbb
输入密码(不能和密文相同) 
The virtual terminal password is used to protect
access 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? [yes]: n
配置简单网管吗?选N
Configure IP? [yes]: y 
配置IP吗?选Y 
Configure IGRP routing? [yes]: n
配置IGRP路由选择协议吗?选N
Configure RIP routing? [no]: 
配置IGRP路由选择协议吗?选N
Configure bridging? [no]: 
配置桥接吗?选N
Async lines accept incoming modems calls. If you will have
users dialing in via modems, configure these lines.

Configure Async lines? [yes]: n
配置异步线路吗?选N
Configuring interface parameters:

Do you want to configure FastEthernet0/0 interface? [yes]: y
您是否想配置fastethernet0/0接口?选Y
Use the 100 Base-TX (RJ-45) connector? [yes]: y
用RJ45的连接器吗?选Y
Operate in full-duplex mode? [no]: y
选用全双工模式?选Y
Configure IP on this interface? [yes]: y
在这个接口上配置IP吗?选Y
IP address for this interface: 192.168.0.1
配置该接口的IP地址(在此地址为192.168.0.1
Subnet 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)
