Cisco 3750文件系统学习总结

现在C3750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
