Cisco 3750文件系统学习总结

现在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
