通州北大青鳥(niǎo)校區(qū):CISCO技術(shù)集合(二)設(shè)置對(duì)話過(guò)程

北京北大青鳥(niǎo)學(xué)校學(xué)術(shù)部老師講解:設(shè)置對(duì)話過(guò)程
1. 顯示提示信息
2. 全局參數(shù)的設(shè)置
3. 接口參數(shù)的設(shè)置
4. 顯示結(jié)果

利用設(shè)置對(duì)話過(guò)程可以避免手工輸入命令的煩瑣,但它還不能完全代替手工設(shè)置,一些特殊的設(shè)置還必須通過(guò)手工輸入的方式完成。(北京北大青鳥(niǎo)學(xué)校)

進(jìn)入設(shè)置對(duì)話過(guò)程后,路由器首先會(huì)顯示一些提示信息:(北京北大青鳥(niǎo)學(xué)校)
--- 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 [].

這是告訴你在設(shè)置對(duì)話過(guò)程中的任何地方都可以鍵入“?”得到系統(tǒng)的幫助,按ctrl-c可以退出設(shè)置過(guò)程,缺省設(shè)置將顯示在‘[]’中。然后路由器會(huì)問(wèn)是否進(jìn)入設(shè)置對(duì)話:
Would you like to enter the initial configuration dialog? [yes]:
如果按y或回車,路由器就會(huì)進(jìn)入設(shè)置對(duì)話過(guò)程。首先你可以看到各端口當(dāng)前的狀況:
First, would you like to see the current interface summary? [yes]:
Any interface listed with OK? value "NO" does not have a valid configuration
Interface IP-Address OK? Method Status Protocol
Ethernet0 unassigned NO unset up up
Serial0 unassigned NO unset up up
……… ……… … …… … …

然后,路由器就開(kāi)始全局參數(shù)的設(shè)置:(北京北大青鳥(niǎo)學(xué)校)
Configuring global parameters:
1.設(shè)置路由器名:
Enter host name [Router]:
2.設(shè)置進(jìn)入特權(quán)狀態(tài)的密文(secret),此密文在設(shè)置以后不會(huì)以明文方式顯示:
The enable secret is a one-way cryptographic secret used
instead of the enable password when it exists.
Enter enable secret: cisco(北京北大青鳥(niǎo)學(xué)校)
3.設(shè)置進(jìn)入特權(quán)狀態(tài)的密碼(password),此密碼只在沒(méi)有密文時(shí)起作用,并且在設(shè)置以后會(huì)以明文方式顯示:
The enable password is used when there is no enable secret
and when using older software and some boot images.
Enter enable password: pass
4.設(shè)置虛擬終端訪問(wèn)時(shí)的密碼:(北京北大青鳥(niǎo)學(xué)校)
Enter virtual terminal password: cisco
5.詢問(wèn)是否要設(shè)置路由器支持的各種網(wǎng)絡(luò)協(xié)議:
Configure SNMP Network Management? [yes]:
Configure DECnet? [no]:
Configure AppleTalk? [no]:
Configure IPX? [no]:
Configure IP? [yes]:
Configure IGRP routing? [yes]:
Configure RIP routing? [no]:
………
6.如果配置的是撥號(hào)訪問(wèn)服務(wù)器,系統(tǒng)還會(huì)設(shè)置異步口的參數(shù):
Configure Async lines? [yes]:
1) 設(shè)置線路的最高速度:(北京北大青鳥(niǎo)學(xué)校)
Async line speed [9600]:
2) 是否使用硬件流控:
Configure for HW flow control? [yes]:
3) 是否設(shè)置modem:
Configure for modems? [yes/no]: yes
4) 是否使用默認(rèn)的modem命令:
Configure for default chat script? [yes]:
5) 是否設(shè)置異步口的PPP參數(shù):
Configure for Dial-in IP SLIP/PPP access? [no]: yes
6) 是否使用動(dòng)態(tài)IP地址:(北京北大青鳥(niǎo)學(xué)校)
Configure for Dynamic IP addresses? [yes]:
7) 是否使用缺省IP地址:
Configure Default IP addresses? [no]: yes
是否使用TCP頭壓縮:
Configure for TCP Header Compression? [yes]:
9) 是否在異步口上使用路由表更新:
Configure for routing updates on async links? [no]: y
10) 是否設(shè)置異步口上的其它協(xié)議。
接下來(lái),系統(tǒng)會(huì)對(duì)每個(gè)接口進(jìn)行參數(shù)的設(shè)置。
1.Configuring interface Ethernet0:
1) 是否使用此接口:
Is this interface in use? [yes]:
2) 是否設(shè)置此接口的IP參數(shù):
Configure IP on this interface? [yes]:
3) 設(shè)置接口的IP地址:
IP address for this interface: 192.168.162.2
4) 設(shè)置接口的IP子網(wǎng)掩碼:
Number of bits in subnet field [0]: (北京北大青鳥(niǎo)學(xué)校)

Class C network is 192.168.162.0, 0 subnet bits; mask is /24
在設(shè)置完所有接口的參數(shù)后,系統(tǒng)會(huì)把整個(gè)設(shè)置對(duì)話過(guò)程的結(jié)果顯示出來(lái):
The following configuration command script was created:
hostname Router
enable secret 5 $1$W5Oh$p6J7tIgRMBOIKVXVG53Uh1
enable password pass
…………
請(qǐng)注意在enable secret后面顯示的是亂碼,而enable password后面顯示的是設(shè)置的內(nèi)容。
顯示結(jié)束后,系統(tǒng)會(huì)問(wèn)是否使用這個(gè)設(shè)置:(北京北大青鳥(niǎo)學(xué)校)

Use this configuration? [yes/no]: yes
如果回答yes,系統(tǒng)就會(huì)把設(shè)置的結(jié)果存入路由器的NVRAM中,然后結(jié)束設(shè)置對(duì)話過(guò)程,使路由器開(kāi)始正常的工作。
(北京北大青鳥(niǎo)學(xué)校,未完待續(xù))
