Description
Use the tftp get command to download a file from a TFTP server, and save it to the local storage
device.
Different from the FTP function, the working directory of a TFTP server cannot be changed or specified
on a TFTP client. To enter another working directory, you need to modify the working directory on the
TFTP server and relog in.
The 3com switch 4500 supports the TFTP file size negotiation function, namely, before downloading a
file, the switch requests the size of the file to be downloaded to the TFTP server, thus to ensure whether
there is enough space on the Flash for file downloading. If the TFTP server also supports the function,
when the file size is too large, the switch can know this in advance and stops the download operation to
save network resources; if the TFTP server does not support the function, the switch can only download
the file to its memory, and delete the file if it finds the file is too large when writing the file to the Flash.
Related commands: tftp put.
