交換機IOS升級實例及相關文件命令

1.查看文件系統,默認是flash.
dir all (flash: )
show file system
2.更改目錄：
cd xx
pwd (查看當前目錄）
3.新建目錄：
mkdir xx
4.刪除目錄：
delete/force(不再詢問確認)/recursive(刪除目錄下的子目錄和文件)
如果是flash: (整個flash)，如果是目錄，則是整個目錄.
不可恢復.
5.創建一個tar文件：
archive tar/creat x...(目的) x...(源)
6.查看一個tar包含的文件：
archive tar/table xxx.tar
7.解壓縮一個tar文件：
archive tar/xtract xxx.tar flash: (解壓縮整個tar,只能解到當前flash)
archive tar/xtract xxx.tar flash:/xxxxx (指定解壓縮整個tar，或其中某個文件，目錄)
8.查看一個可讀文件的內容：
more xxx (可以是遠程的,如TFTP)
9.配置文件：
Switch# copy tftp://172.16.2.155/tokyo-confg system:running-config (多了個system
Switch# copy system:running-config tftp://172.16.2.155/tokyo-confg (多了個system
10.升級IOS文件：
archive download-sw/overwrite(覆蓋原IOS)/reload(重啓) ftp://x.tar
或archive download-sw/leave-old-sw(保留原IOS)/reload(重啓) ftp://x.tar時會有算法來驗證新IOS是否適合當前模塊和內存,否則會報錯.
如查選用/overwrite,不管down的IOS是否與現在相同,都會被刪除.

downloaddownload完成後,會自動將boot參數指向新IOS.
11.上傳IOS文件：
archive upload-sw ftp://x.tar
上傳算法會自動把多個系統文件生成爲.tar ,並上傳.
