可以看出cisco的交换机的镜像备份成功

怎么还原呢？？

怎么从tftp服务器下载的
ISO启动呢

1. 删除原有的文件
   

sw1#show  flashDirectory of flash:/1  -rw-     3058048            c2950-i6q4l2-mz.121-22.EA4.bin2  -rw-     3058048            c2950-test.bin64016384 bytes total (57900288 bytes free)sw1#delesw1#delete  c2950-i6q4l2-mz.121-22.EA4.binDelete filename [c2950-i6q4l2-mz.121-22.EA4.bin]?Delete flash:/c2950-i6q4l2-mz.121-22.EA4.bin?

2.特权模式下

sw1(config)#boot system  c2950-test.bin

3.都不要忘记保存

测试：

sw1#reloadProceed with reload?

反思：交换机属于二层设备，需要配置管理地址

路由器属于三层设备 有端口启动就可以

路由器的备份和恢复和交换机的命令一样
