Downloading an Image File By Using TFTP

You can download a new image file and replace the current image or keep the current image.

Beginning in privileged EXEC mode, follow Steps 1 through 3 to download a new image from a TFTP

server and overwrite the existing image. To keep the current image, go to Step 3.

Ensure that the switch has a route to the TFTP server. The switch and the TFTP server must be in

the same subnetwork if you do not have a router to route traffic between subnets. Check connectivity

to the TFTP server by using the ping command.

Ensure that the image to be downloaded is in the correct directory on the TFTP server (usually

/tftpboot on a UNIX workstation).

For download operations, ensure that the permissions on the file are set correctly. The permission

on the file should be world-read.

Before uploading the image file, you might need to create an empty file on the TFTP server. To

create an empty file, enter the touch filename command, where filename is the name of the file you

will use when uploading the image to the server.

During upload operations, if you are overwriting an existing file (including an empty file, if you had

to create one) on the server, ensure that the permissions on the file are set correctly. Permissions on

the file should be world-write.
