TFTP Approach
With this approach, you can use the copy command to copy the 3Com Router

Start the TFTP server and connect it with the router before using this method to
back up the 3Com Router main software. Then, execute the following command
in system view.

FTP Approach
The procedure of backing up the 3Com Router main program software with FTP is
the same as loading the software with FTP, except for
step 6. See “FTP Approach”
on page 41 for reference. When backing up the software with FTP, however, the
step 6 described in “FTP Approach” on page 41 should be modified as follows:
At the prompt ftp>, use the get RemoteFile [LocalFile] command to upload
the specified file to the router. RemoteFile should use the name of the system file
on the router, and the name is case sensitive. You can use the
ftp-server
config-name
command to modify the file name on the router. For details, refer to
“FTP Approach” on page 44.
