2路由器交換機配置基礎(chǔ)課件

1、路由器交換機配置基礎(chǔ)啟動界面 - 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 .Continue with configuration dialog? yes/no: yesEnter IP address: ip_addressEnter IP netmask: ip_netmask

2、Would you like to enter a default gateway address? yes: yesIP address of the default gateway: ip_addressEnter a host name: host_nameEnter enable secret: secret_passwordWould you like to configure a Telnet password? yes yesEnter Telnet password: telnet_passwordWould you like to enable as a cluster co

3、mmand switch? noEnter cluster name: cls_name路由器對話模式任何時候可以按ctrl+c鍵退出對話模式出廠缺省配置 - System Configuration Dialog -Continue with configuration dialog? yes/no: yesAt 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 brac

4、kets .Basic management setup configures only enough connectivityfor management of the system, extended setup will ask youto configure each interface on the systemWould you like to enter basic management setup? yes/no: no缺省端口狀態(tài)First, would you like to see the current interface summary? yes:InterfaceI

5、P-AddressOK?Method Status ProtocolBRI0unassignedYES unset administratively down downBRI0:1unassignedYES unset administratively down downBRI0:2unassignedYES unset administratively down downEthernet0unassignedYES unset administratively down downSerial0unassignedYES unset administratively down down缺省全局

6、配置Configuring global parameters: Enter host name Router:wg_ro_c 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: cisco The enable password is used when you do

7、not specify an enable secret password, with some older software versions, and some boot images. Enter enable password: sanfran The virtual terminal password is used to protect access to the router over a network interface. Enter virtual terminal password: sanjose Configure SNMP Network Management? n

8、o:缺省協(xié)議配置 Configure LAT? yes: no Configure AppleTalk? no: Configure DECnet? no: Configure IP? yes: Configure IGRP routing? yes: no Configure RIP routing? no: Configure CLNS? no: Configure IPX? no: Configure Vines? no: Configure XNS? no: Configure Apollo? no:缺省端口配置BRI interface needs isdn switch-type

9、to be configured Valid switch types are : 0 none.Only if you dont want to configure BRI. 1 basic-1tr6.1TR6 switch type for Germany2 basic-5ess.AT&T 5ESS switch type for the US/Canada3 basic-dms100.Northern DMS-100 switch type for US/Canada 4 basic-net3.NET3 switch type for UK and Europe5 basic-ni.Na

11、nterface? no: yes Configure IP on this interface? no: yes IP address for this interface: 3 Subnet mask for this interface : Class A network is , 24 subnet bits; mask is /24Do you want to configure Serial0 interface? no:配置模式Exec用戶模式用戶模式對交換機和路由器的有限操作命令提示符為 hostn

12、ame模式一:用戶模式wg_ro_c?Exec commands: access-enable Create a temporary Access-List entry atmsig Execute Atm Signalling Commands cd Change current device clear Reset functions connect Open a terminal connection dir List files on given device disable Turn off privileged commands disconnect Disconnect an e

13、xisting network connection enable Turn on privileged commands exit Exit from the EXEC help Description of the interactive help system lat Open a lat connection lock Lock the terminal login Log in as a particular user logout Exit from the EXEC- More -Exec特權(quán)模式特權(quán)(或enabled)模式對交換機和路由器更深入的操作有配置和監(jiān)視權(quán)力是進入其它配

14、置模式的前提命令提示符為 hostname#模式二 (也是最常用的模式):特權(quán)模式wg_ro_c#?Exec commands: access-enable Create a temporary Access-List entry access-profile Apply user-profile to interface access-template Create a temporary Access-List entry bfe For manual emergency modes setting cd Change current directory clear Reset funct

15、ions clock Manage the system clock configure Enter configuration mode connect Open a terminal connection copy Copy from one file to another debug Debugging functions (see also undebug) delete Delete a file dir List files on a filesystem disable Turn off privileged commands disconnect Disconnect an e

17、(config)#interface e0/1wg_sw_a(config-if)#幫助機制上下文關(guān)聯(lián)幫助錯誤信息提示指出所輸入交換機命令的錯誤所在，以便于修改或糾正.可以重新調(diào)出以前運行過的命令，用來再次運行、查看或修改. 之前命令保存區(qū)提供命令清單和與特定命令相關(guān)聯(lián)的參數(shù). 上下文幫助信息Router# clock set 19:56:00% Incomplete command.Router# clock set 19:56:00 ?
