Example
Flash/File Commands
These commands are used to manage the system code or configuration files.
copy
This command moves (upload/download) a code image or configuration file
between the switch’s flash memory and a TFTP server. When you save the system
code or configuration settings to a file on a TFTP server, that file can later be
downloaded to the switch to restore system operation. The success of the file
transfer depends on the accessibility of the TFTP server and the quality of the
network connection.
