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 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]: Return
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 configuration
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 | Protocol | ||||||||
| 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:
