安装向导
========
对于每一个路由器来说,都有一个控制台接口(Console),管理员可以通过RS-232
线缆把控制口和一个终端的主口连接起来,通过这个终端对路由器进行配置.
终端通讯参数设置为:
速度: 9600bps
起始位: 1位
数据位: 8位
停止位: 1或2位
校验: 无
待终端通讯参数设置完毕后,接好路由器控制台,请先打开终端电源,后开路由器电
源,之后就进入初始配置了.屏幕出现(以Cisco 2501为例):

大约停顿1-2分钟,系统调入boot,请耐心等待

--- System Configuration Dialog ---
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 '[]'.
Would you like to enter the initial configuration dialog? [yes]:Return
你是否要进入初始化配置?默认"是".
First, would you like to see the current interface summary? [yes]:Retu
rn
首先,你是否想看一下当前端口的状态?默认"是".
Any interface listed with OK? value "NO" does not have a valid configu
ration
下面会列出当前路由器所具有的硬件配置(包括局域网口和广域网口,以及个端口
当前状态等等.)
Interface IP-Address OK? Method Status Protoc
ol
Ethernet0 unassigned NO unset up down
Serial0 unassigned NO unset down down
Serial1 unassigned NO unset down down
Configuring global parameters:
Enter host name [Router]: JSRouter
设置系统名,如JSRouter.
The enable secret is a one-way cryptographic secret used
instead of the enable password when it exists.
Enter enable secret: cisco
设置进入priviledged EXEC 的密码
The enable password is used when there is no enable secret
and when using older software and some boot images.
Enter enable password: cisco1 (1)
Enter virtual terminal password: cisco
设置进入虚拟终端登录到路由器的口令,即远程登录(telnet)的口令
Configure SNMP Network Management? [yes]:Return
是否设置简单网管协议?
Community string [public]:Return
Configure IP? [yes]:Return
是否设置IP协议?
Configure IGRP routing? [yes]:Return (2)
是否设置IGRP 路由协议?
Your IGRP autonomous system number [1]:Return (3)
你的IGRP 路由协议自治系统号(AS),默认为1.
Configuring interface parameters:
下面配置端口参数
Configuring interface Ethernet0:Return
Is this interface in use? [yes]:Return
Configure IP on this interface? [yes]:Return
IP address for this interface: 1.1.1.1
Number of bits in subnet field [0]:Return (4)
Class A network is 1.0.0.0, 0 subnet bits; mask is /8
以上是配置以太口0,假设IP地址是1.1.1.1,掩码是255.0.0.0.
Configuring interface Serial0:Return
Is this interface in use? [yes]:Return
Configure IP on this interface? [yes]:Return
Configure IP unnumbered on this interface? [no]:Return
IP address for this interface: 2.1.1.1
Number of bits in subnet field [0]:Return
Class A network is 2.0.0.0, 0 subnet bits; mask is /8
以上是配置串口0,假设IP地址是2.1.1.1,掩码是255.0.0.0.
Configuring interface Serial1:Return
Is this interface in use? [yes]: no
以上是当不需要用串口1时,请敲入no.
The following configuration command script was created:
hostname JSRouter

Use this configuration? [yes/no]: yes (5)
确认当前配置后,把当前配置写入NVRAM 中.这样以后开机自动把配置调入内存,不
需要重新配置了.

JSRouter>en
Password:(敲入密码,不反显的)
JSRouter#
备注:
Enter enable password:-----这个口令是对于IOS 10.2以下版本适用,在IOS 10
.3以上版本均使用secret,不再用password.在配置文件中, secret是加密显示的
.
现在我们通常都在IOS 10.3 版本以上,故无需password这个口令.
另外,password和secret不能相同.
在初始配置中,默认的路由协议是IGRP,若敲入yes,则生成IGRP路由协议.假如不想
使用IGRP协议,则打No,在配置模式下(conf t)选择路由协议.
自治系统 (autonomous system)-----它是一个域的概念.路由协议在一个 自制系
统中可以交换路由信息,而在两个自制系统之间是不能直接传递路由信息的,必须
通过类似网际路由协议才能互相通讯.这样就大大地缩小了路由表,减少它占用的
带宽量,使网络具有扩展性.
Number of bits in subnet field [0]-----掩码子网的位数.举例说明:
掩码为255.0.0.0的掩码子网位数是0,掩码共8位
掩码为255.255.0.0的掩码子网位数8,掩码共16位
掩码为255.255.255.0的掩码子网位数16,掩码共24位
掩码为255.255.255.252的掩码子网位数22,掩码共30位
Cisco命令系统是即时生效的,也就是说,配置完后立即执行,但若不写入NVRAM 中
,关掉电源后就会丢失.你若想保留更改的配置,请敲入write命令.
Windows 95/NT 下,超级终端的设置.
在 开始--->程序--->附件--->超级终端--->Hypetrm
设定名称为cisco,再选择一个图标.
请选择"直接连接到串口1"
选择波特率为9600bps.
最后把设置的保存在cisco文件里.下一次直接从超级终端cisco中启动.
