下載檔案 從TFTP

本機需先架設TFTP 將檔案放置TFTP 再從switch 使用以下指令下載 官網http://tftpd32.jounin.net/

Switch#copy tftp flash:  #將檔案從TFTP Server 下載下來

刪除不需要的影像檔

若一般要刪除flash中的檔案， 會執行delete或rmdir delete主要是刪除檔案非資料夾。 rmdir是刪除資料夾，但資料夾內要為空。

rmdir flash:<path>

列出資料夾內檔案(可略過)

Switch#dir flash:/c2960x-universalk9-mz.152-4.E8
Directory of flash:/c2960x-universalk9-mz.152-4.E8/

   7 -rwx      687 Jul 5 2019 19:43:02 +08:00  info

 693 -rwx 24359936 Jul 5 2019 19:46:31 +08:00  c2960x-universalk9-mz.152-4.E8.bin

刪除不需要的影像檔

Switch#delete /recursive /force flash:/c2960x-universalk9-mz.152-4.E8
