Open Network Install Environment (ONIE) is the combination of a boot loader and a small operating system for bare metal network devices that provides an environment for automated provisioning or recovery of the device. The SLX device boots SLX-OS from the images stored on the hard disk of the device. Extreme installs these images before shipping the SLX devices. ONIE also provides mechanisms to re-install or update SLX-OS if the normal software download process fails.
The firmware download command updates the ONIE image and diag OS images automatically as part of the process. You do not need to run the onie install and diag install commands to install the ONIE image and diag OS image.
The process supported by the firmware download command is not affected by this feature. The SLX-OS software is not updated to the snapshot partition during the normal upgrade process.
For more information about ONIE, see the Open Compute Project website.
