Using HTTP for File Transfers
Stating with Release 9.3(0.1), you can use HTTP to copy files or configuration details to a remote server.
Use the copy source-file-url http://host[:port]/file-path command to transfer files to an external server.
Enter the following source-file-url keywords and information:
• To copy a file from the internal FLASH, enter flash:// followed by the filename.
• To copy the running configuration, enter the keyword running-config.
• To copy the startup configuration, enter the keyword startup-config.
• To copy a file on the external FLASH, enter usbflash:// followed by the filename.
Upgrading and Downgrading the Dell Networking OS
NOTE: To upgrade the Dell Networking OS, refer to the Release Notes for the version you want to
load on the system.
Using Hashes to Validate Software Images
You can use the MD5 message-digest algorithm or SHA256 Secure Hash Algorithm to validate the
software image on the flash drive, after the image has been transferred to the system, but before the
image has been installed. The validation calculates a hash value of the downloaded image file on system’s
flash drive, and, optionally, compares it to a Dell Networking published hash for that file.
The MD5 or SHA256 hash provides a method of validating that you have downloaded the original
software. Calculating the hash on the local image file, and comparing the result to the hash published for
that file on iSupport, provides a high level of confidence that the local copy is exactly the same as the
published software image. This validation procedure, and the verify {md5 | sha256} command to support
it, can prevent the installation of corrupted or modified images.
The verify {md5 | sha256} command calculates and displays the hash of any file on the specified local
flash drive. You can compare the displayed hash against the appropriate hash published on i-Support.
Optionally, the published hash can be included in the verify {md5 | sha256} command, which will display
whether it matches the calculated hash of the indicated file.
