Using an Image File's MD5 Checksum To Verify Its Integrity If you download an image file from the D-link support site and install it in a switch's boot partition, you can verify that the file has not been corrupted while being copied. md5 [boot0: | boot1:]filename To verify an image file's integrity: 1. Download the image file from the D-Link support site onto a TFTP server, and use the CLI copy tftp command on the switch to copy the image onto the switch's nonvolatile storage. 2. On the switch, use the dir command to display the contents of nonvolatile storage. 3. Enter a command such as the following to calculate the checksum for the file: pubs# md5 boot0:040003.020 MD5 (boot0:MX040003.020) = b9cf7f527f74608e50c70e8fb896392a 4. Compare the checksum on the support site with the checksum calculated by the switch. If they match, then the file has not been corrupted. 5. If you have not already done so, use the set boot partition command to configure the switch to boot from the partition containing the new image. 6. Use the reset system [force] command to restart the switch using the new image. D-Link DWS-1008 User Manual 404
