Upgrading Dell EMC Networking OS

To upgrade Dell EMC Networking Operating System (OS), refer to the Release Notes for the version you want to load on the

system.

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 EMC 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.

However, these changes are backward-compatible and do not affect existing behavior; meaning, you can still use the ip http

source- interface command to communicate with a particular interface even if no VRF is configured on that interface

NOTE: If the HTTP service is not VRF-aware, then it uses the global routing table to perform the look-up.

To enable an HTTP client to look up the VRF table corresponding to either management VRF or any nondefault VRF, use the ip

http vrf command in CONFIGURATION mode.

● Configure an HTTP client with a VRF that is used to connect to the HTTP server.

CONFIGURATION MODE

DellEMC(conf)#ip http vrf {management | <vrf-name>}

Verify Software Images Before Installation

To validate the software image on the flash drive, you can use the MD5 message-digest algorithm or SHA256 Secure Hash

Algorithm, after the image is transferred to the system but before the image is installed. The validation calculates a hash value

of the downloaded image file on system’s flash drive, and, optionally, compares it to a Dell EMC 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, prevents 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 iSupport. Optionally, you can include the published

hash in the verify {md5 | sha256} command, which displays whether it matches the calculated hash of the indicated file.
