cisco 交换机 FLASH 恢复方法(CU)
一台cisco 3500不小心删除了FLASH 文件，不能正常BOOT，急，没地方有启动文件下载，也联系不上cisco ，正急时，我发现网络中还有台cisco3550，于是通过TFTP ,进入/FLASH 目录中，把其中的三个重要启动文件，备份下来，然后打开已不行的那台交换机，等到 SWITCH 提示后，采用XMDOEM方法传送文件到FLASH 目录中，（BOOT XMDOEM /FLASH/ ） ，过两个小时后，三个文件传送完毕，重新启动后，一切OK！
下面是具体操作信息：
The system is unable to boot automatically because there
are no bootable files to boot.

switch: ?
           ? -- Present list of available commands
        boot -- Load and boot an executable image
         cat -- Concatenate (type) file(s)
        copy -- Copy a file
      delete -- Delete file(s)
         dir -- List files in directories
  flash_init -- Initialize flash filesystem(s)
      format -- Format a filesystem
        fsck -- Check filesystem consistency
        help -- Present list of available commands
load_helper -- Load and initialize a helper image
      memory -- Present memory heap utilization information
       mkdir -- Create dir(s)
        more -- Concatenate (display) file(s)
      rename -- Rename a file
       reset -- Reset the system
       rmdir -- Delete empty dir(s)
         set -- Set or display environment variables
      set_bs -- Set attributes on a boot sector filesystem
   set_param -- Set system parameters in flash
       sleep -- Sleep a specified number of seconds
        trap -- Cause a software breakpoint to occur
-- MORE --
                   type -- Concatenate (type) file(s)
       unset -- Unset one or more environment variables
     version -- Display boot loader version
switch: version            ;看交换机版本。
