Copying Image Files Using TFTP

Copying Image Files Using TFTP
You can download a switch image from a TFTP server or upload the image from the switch to a TFTP server.
You download a switch image file from a server to upgrade the switch software. You can overwrite the current
image with the new one or keep the current image after a download.
You upload a switch image file to a server for backup purposes; this uploaded image can be used for future
downloads to the same or another switch of the same type .
Instead of using the copy privileged EXEC command or the archive tar privileged EXEC command, we
Note
recommend using the archive download-sw and archive upload-sw privileged EXEC commands to
download and upload software image files. For switch stacks, the archive download-sw and archive
upload-sw privileged EXEC commands can only be used through the stack master. Software images
downloaded to the stack master are automatically downloaded to the rest of the stack members.
To upgrade a switch with an incompatible software image, use the archive copy-sw privileged EXEC
command to copy the software image from an existing stack member to the incompatible switch. That
switch automatically reloads and joins the stack as a fully functioning member.
Preparing to Download or Upload an Image File By Using TFTP
