CISCO路由器初始配置簡介
很多初學路由器知識的網友對路由器的初始配置可能感到很陌生,本人在初學時也很困惑,因為一下出來很多提問不知如何是好,下面將最近剛調試的一臺CISCO3640的初始配置整理出來與各位網友交流,如有疏漏之處,還請大家指正。
1.用CISCO隨機帶CONSOLE線,一端連在CISCO路由器的CONSOLE口,一端連在計算機的COM口。
2.打開電腦,啟動超級終端.為您的連接取個名字,比如CISCO_SETUP,下一步選定連接時用COM1,下一步選定第秒位數9600,數據位8,奇偶校驗無,停止位1,數據流控制無.最后選確定。
3.打開路由器電源,這時超級終端將出現以下畫面:

--- System Configuration Dialog ---
Would you like to enter the initial configuration dialog? [yes/no]: y
您是否進入初始化配置對話,選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
您是否進入基本配置安裝,選N
First, would you like to see the current interface summary? [yes]: y
首先,您是否看一下當前端口狀態
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
輸入路由器的名字
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
輸入密文
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
輸入密碼(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
輸入虛擬終端的密碼(以備遠程登錄)
Configure SNMP Network Management? [yes]: n
配置簡單網管嗎?選N
Configure IP? [yes]: y
配置IP嗎?選Y
Configure IGRP routing? [yes]: n
配置IGRP路由選擇協議嗎?選N
Configure RIP routing? [no]:

Configure bridging? [no]:
配置橋接嗎?選N
Async lines accept incoming modems calls. If you will have
users dialing in via modems, configure these lines.
Configure Async lines? [yes]: n
配置異步線路嗎?選N
Configuring interface parameters:
Do you want to configure FastEthernet0/0 interface? [yes]: y
