交换机IOS和配置文件的备份与还原

1.备份IOS和配置文件

1.首先要有一个配置好的ftp服务器，并且保证要在一个网段中（能够互相的ping通）。

实例：

Switch#copy flash: tftp:

Source filename []? c2960-lanbase-mz.122-25.FX.bin

Address or name of remote host []? 192.168.1.2

Destination filename [c2960-lanbase-mz.122-25.FX.bin]?

Writing c2960-lanbase-mz.122-

25.FX.bin...!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

!!!!!

[OK - 4414921 bytes]

这样就将一个IOS备份到了ftp服务器上，这个可以对IOS的升级和重装提供便利。

2.恢复IOS和配置文件

实例：

Switch#copy tftp flash: 

Address or name of remote host []? 192.168.1.2

Source filename []? c2960-lanbase-mz.122-25.FX.bin

Destination filename [c2960-lanbase-mz.122-25.FX.bin]? 

%Warning:There is a file already existing with this name
