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):

System Bootstrap, Version 5.2(5), RELEASE SOFTWARE

2500 processor with 2048 Kbytes of main memory

大约停顿1-2分钟,系统调入boot,请耐心等待

cisco 2500 (68030) processor (revision D) with 2048K/2048K bytes of me

mory.

Processor board ID 02327592, with hardware revision 00000000

Bridging software.

X.25 software, Version 2.0, NET2, BFE and GOSIP compliant.

1 Ethernet/IEEE 802.3 interface(s)

2 Serial network interface(s)

32K bytes of non-volatile configuration memory.

8192K bytes of processor board System flash (Read ONLY)

Notice: NVRAM invalid, possibly due to write erase.

--- 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

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

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

enable secret 5 $1$Bv.r$j/Zm2B6jw9UTQPxLGZjAz.

enable password cisco1

line vty 0 4

password cisco

snmp-server community public

ip routing

interface Ethernet0

ip address 1.1.1.1 255.0.0.0

interface Serial0

ip address 2.1.1.1 255.0.0.0

interface Serial1

shutdown

no ip address

router igrp 1

network 1.0.0.0

network 2.0.0.0

end

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.

Building configuration...

Use the enabled mode 'configure' command to modify this configuration.

Press RETURN to get started!

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.
