Cisco 3750文件系统学习总结
http://www.21tx.com 2005年08月02日 中国IT认证实验室
  现在对CISCO 3750的文件系统做一个总结。
  
  查看文件系统。默认是flash.
  
  dir all (flash: )
  
  show file system
  
  更改目录:
  
  cd xx
  
  pwd (查看当前目录)
  
  新建目录:
  
  mkdir xx
  
  删除目录:
  
  delete/force(不再询问确认)/recursive(删除目录下的子目录和文件)
  
  如果是flash: (整个flash),如果是目录,则是整个目录。
  
  不可恢复。
  
  copy,还是复制。
  
  创建一个tar文件:
  
  archive tar/creat x...(目的) x...(源)
  
  查看一个tar包含的文件:
  
  archive tar/table xxx.tar
  
  解压缩一个tar文件:
  
  archive tar/xtract xxx.tar flash: (解压缩整个tar,只能解到当前flash)
  
  archive tar/xtract xxx.tar flash:/xxxxx (指定解压缩整个tar,或其中某个文件,目录)
  
  查看一个可读文件的内容:
  
  more xxx (可以是远程的,如TFTP)
  
  
  配置文件:
  
  Switch# copy tftp://172.16.2.155/tokyo-confg system:running-config (多了个system
  
  Switch# copy system:running-config tftp://172.16.2.155/tokyo-confg (多了个system
  
  cisco.com上提供的ios为tar格式。包含的文件见文档。
  
  升级IOS文件:
  
  archive download-sw/overwrite(覆盖原IOS)/reload(重启) ftp://x.tar
  
  或者
  
  archive download-sw/leave-old-sw(保留原IOS)/reload(重启) ftp://x.tar
  
  download时会有算法来验证新IOS是否适合当前模块和内存,否则会报错。
  
  如查选用/overwrite,不管down的IOS是否与现在相同,都会被删除。
  
  download完成后,会自动将boot参数指向新IOS。
  
  (文档虽然没讲,但是我想,有足够flash空间的情况下,还是不要覆盖原IOS,传完再删)
  
  
  上传IOS文件:
  
  archive upload-sw ftp://x.tar
  
  上传算法会自动把多个系统文件生成为.tar ,并上传。
  
  (详细系统组成文件见文档937页):info, the Cisco IOS image, and the web management files.
  
  IOS恢复参见文档里的Troubleshooting部分
  
  升级前后对比:
