Appendix B Working with the Cisco IOS File System, Configuration Files, and Software Images Working with Software Images • 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. 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, skip Step 3. Step 1 Step 2 Step 3 Step 4 Command archive download-sw /overwrite /reload tftp:[[//location]/directory]/image-name.tar archive download-sw /leave-old-sw /reload tftp:[[//location]/directory]/image-name.tar Purpose Copy the image to the appropriate TFTP directory on the workstation. Make sure the TFTP server is properly configured; see the "Preparing to Download or Upload an Image File By Using TFTP" section on page B-22. Log into the switch through the console port or a Telnet session. Download the image file from the TFTP server to the switch, and overwrite the current image. • The /overwrite option overwrites the software image in Flash memory with the downloaded image. • The /reload option reloads the system after downloading the image unless the configuration has been changed and not been saved. • For //location, specify the IP address of the TFTP server. • For /directory/image-name.tar, specify the directory (optional) and the image to download. Directory and image names are case sensitive. Download the image file from the TFTP server to the switch, and keep the current image. • The /leave-old-sw option keeps the old software version after a download. • The /reload option reloads the system after downloading the image unless the configuration has been changed and not been saved. • For //location, specify the IP address of the TFTP server. • For /directory/image-name.tar, specify the directory (optional) and the image to download. Directory and image names are case sensitive. The download algorithm verifies that the image is appropriate for the switch model and that enough DRAM is present, or it aborts the process and reports an error. If you specify the /overwrite option, the download algorithm removes the existing image on the Flash device whether or not it is the same as the new one, downloads the new image, and then reloads the software. 78-16156-01 Catalyst 3560 Switch Software Configuration Guide B-23
