Cisco IOS File System Commands-1

1.copy run ftp://username:password@202.xxx.yy.26/directory/file-3845-webvpn-config.txt
2.archive download-sw /overwrite /reload ftp://@124.X.Z.129/c2960-lanbasek9-tar.122-52.SE.tar
此方式是讓switch去ftp下載IOS, 新IOS會覆蓋設備上原IOS. 安裝後會自行重開機.
ftp username, password都已在global下好了.如下:
ip ftp username anonymous
ip ftp password 123@
