案例10：备份和恢复

案例10：备份与恢复1.案例目标通过本案例，你可以掌握如下技能：备份CiscoIOS恢复CiscoIOS备份启动配置与运行配置恢复启动配置与运行配置3.设备与拓扑设备：1台Laptop-PT，1台Server-PT，1台2811路由器。拓扑：如下列图。4.操作步骤步骤1：按以上拓扑添加和连接设备。步骤2：配置路由器与效劳器的IP地址Router#configureterminalR1(config)#interfaceFastEthernet0/1R1(config-if)#ipaddressR1(config-if)#注意，效劳器的IP地址可使用IPConfiguration进行配置，简单快捷。步骤3：验证路由器与效劳器之间的连通性Typeescapesequencetoabort.Sending5,100-byteICMPEchosto,timeoutis2seconds:!!!!!Successrateis100percent(5/5),round-tripmin/avg/max=31/31/32msR1#步骤4：查看路由器flash中的CiscoIOS镜像R1#shflash:Systemflashdirectory:FileLengthName/status350938004228282sigdef-category.xml1227537sigdef-default.xml[51193823bytesused,12822561available,64016384total]63488KbytesofprocessorboardSystemflash(Read/Write)R1#//注意CiscoIOS镜像的大小与文件名步骤5：备份CiscoIOS到TFTP效劳器R1#copyflash:tftp:Sourcefilename[]?Addressornameofremotehost[]? //TFTP效劳器地址Destinationfilename[c2800nm-advipservicesk9-mz.124-15.T1.bin]?Writingc2800nm-advipservicesk9-mz.124-15.T1.bin...!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!………[OK-50938004bytes]50938004bytescopiedin27.828secs(1830000bytes/sec)R1#步骤6：在TFTP效劳器上验证备份翻开效劳器的Config页面，单击TFTP按钮，可见右边窗口已有备份的CiscoIOS镜像。步骤7：从TFTP效劳器恢复〔升级〕CiscoIOS假设TFTP效劳器上要想恢复或升级的CiscoIOS镜像是：R1#copytftp:flash:Addressornameofremotehost[]? //TFTP效劳器地址Sourcefilename[]?Destinationfilename[c2800nm-ipbase-mz.123-14.T7.bin]?:!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!![OK-5571584bytes]5571584bytescopiedin3.268secs(390641bytes/sec)R1#步骤8：验证恢复或升级R1#shflash:Systemflashdirectory:FileLengthName/status65571584c2800nm228282sigdef-category.xml1227537sigdef-default.xml[56765407bytesused,7250977available,64016384total]63488KbytesofprocessorboardSystemflash(Read/Write)R1#步骤9：验证NVRAM中的启动配置和运行配置R1#dirnvram:Directoryofnvram:/238-rw-490<nodate>startup-config490bytestotal(237588bytesfree)R1#//注意启动配置的文件名及其长度。R1#shrunBuildingconfiguration...Currentconfiguration:548bytes //运行配置的长度………R1#R1#shstartUsing548bytes //启动配置的长度!version12.3………R1#步骤10：备份启动配置与运行配置备份启动配置R1#copystartup-configtftp:Addressornameofremotehost[]?Destinationfilename[R1-confg]?R1-startup-configWritingstartup-config...!![OK-548bytes]548bytescopiedin0.062secs(8000bytes/sec)R1#备份运行配置R1#copyrunning-configtftp:Addressornameofremotehost[]?Destinationfilename[R1-confg]?R1-running-configWritingrunning-config...!![OK-548bytes]548bytescopiedin0.063secs(8000bytes/sec)R1#在TFTP效劳器上验证备份翻开效劳器的Config页面，单击TFTP按钮，可见右边窗口已有备份的启动和运行配置。步骤11：恢复启动配置与运行配置恢复到启动配置R1#copytftp:startup-configAddressornameofremotehost[]?Sourcefilename[]?R1-startup-configDestinationfilename[startup-config]?:![OK-548bytes]548bytescopiedin0.032secs(17125bytes/sec)R1#恢复到运行配置R1#copytftp:running-configAddressornameof
