command in EXEC mode.
• md5 : MD5 message-digest algorithm
•
sha256
: SHA256 Secure Hash Algorithm
•
flash:
(Optional) Specifies the flash drive. The default uses the flash drive. You can enter the image file name.
•
hash-value
: (Optional). Specify the relevant hash published on iSupport.
• img-file : Enter the name of the Dell Networking software image file to validate

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. To transfer files to an external
server, use the
copy source-file-url http://host[:port]/file-path command.
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 USB device, enter usbflash:// followed by the filename.
In the Dell Networking OS release 9.8(0.0), HTTP services support the VRF-aware functionality. If you want the HTTP server to use a VRF
table that is attached to an interface, configure that HTTP server to use a specific routing table. You can use the
ip http vrf
command
to inform the HTTP server to use a specific routing table. After you configure this setting, the VRF table is used to look up the destination
address.
NOTE: To enable HTTP to be VRF-aware, as a prerequisite you must first define the
VRF.
You can specify either the management VRF or a nondefault VRF to configure the VRF awareness setting.
When you specify the management VRF, the copy operation that is used to transfer files to and from an HTTP server utilizes the VRF table
corresponding to the Management VRF to look up the destination. When you specify a nondefault VRF, the VRF table corresponding to
that nondefault VRF is used to look up the HTTP server.
