CISCO 路由器初始配置简介

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 Bootstrap, Version 11.1(20)AA2, EARLY DEPLOYMENT RELEASE SOFTWARE (fc1)

--- 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)

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Y

Some supported encapsulations are

ppp/hdlc/frame-relay/lapb/x25/atm-dxi/smds

Choose 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? [no]:

IP address for this interface: 172.16.0.5

配置该接口的IP地址(在此地址为172.16.0.5)

Subnet mask for this interface [255.255.0.0] : 255.255.255.252

配置该接口的子网掩码.(默认的是255.255.0.0,可以手工输入修改为255.255.255.252) Class B network is 172.16.0.0, 30 subnet bits; mask is /30

(以下配置同上)

Do you want to configure FastEthernet0/1 interface? [yes]:

Use the 100 Base-TX (RJ-45) connector? [yes]:

Operate in full-duplex mode? [no]: y

Configure IP on this interface? [yes]: y
