实验目的
l学习如何备份IOS文件
l学习TFTP软件如何使用
实验说明
升级IOS的过程同备份IOS过程类似
注意PC与路由器的UTP线的类型
实验拓扑图
基本配置
Router#conf t Enter configuration commands, one per line. End with CNTL/Z. Router(config)#hostname test_router test_router(config)#int Fa0/0 test_router(config-if)#ip address 192.168.10.1 255.255.255.0 test_router(config-if)#no shut PC IP： 192.168.10.2 子网掩码：255.255.255.0 网关： 192.168.10.1 PC要安装TFTP服务器端软件，此实验使用3Cdeamon{个人使用感觉，比cisco的tftp软件好用}软件 |
实验步骤
1. 测试网络联通性：{不要忘记关闭PC系统自带及杀毒软件带的防火墙}
test_router#ping 192.168.10.2 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 192.168.10.2, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms test_router# |
2. 启用TFTP服务器：
|
3. 配置TFTP服务器的根目录:
Configure TFTP Server à TFTP Configuration:
{将根目录设定D：} |
4. 备份IOS:
test_router#sh flash: System flash directory: File Length Name/status 1 7754580 c2600-i-mz.123-26.bin{IOS文件名，大多以 “.bin”结尾} [7754644 bytes used, 633964 available, 8388608 total] 8192K bytes of processor board System flash (Read/Write) test_router#copy flash: tftp{开始备份IOS} Source filename []? c2600-i-mz.123-26.bin{设定源文件} Address or name of remote host []? 192.168.10.2{设定TFTP服务器地址} Destination filename [c2600-i-mz.123-26.bin]?{定义目标文件名} !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!{！代表开始copy文件} 7754580 bytes copied in 55.34 secs (140992 bytes/sec) 结束后可以到D盘下查看备份的文件 |
5.实验完成
