Copying Image Files By 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.

Note

Instead of using the copy privileged EXEC command or the archive tar privileged EXEC command, we
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

make sure that the /etc/inetd.conf file contains this line:

tftp dgram udp wait root /usr/etc/in.tftpd in.tftpd -p -s /tftpboot

Make sure that the /etc/services file contains this line:

tftp 69/udp

total_image_file_size
