Install, License, and Upgrade Configuration
The OcNOS Installation Guide provides instructions for installing the OcNOS software, including the correct license. It includes the following steps:
|
•
|
Download the OcNOS installation image. |
|
•
|
Download an OcNOS license. |
|
•
|
From an FTP, HTTP/HTTPS, or TFTP server |
|
•
|
Using Zero Touch Provisioning (ZTP) |
USB restoration disables ZTP.
OcNOS supports both patch upgrades and full upgrades:
|
•
|
A patch upgrade updates the software with a new OcNOS image that includes bug fixes, but does not involve changes to the kernel. |
|
•
|
A full upgrade updates the software with a new OcNOS ONIE image, including bug fixes and kernel changes. |
Installing OcNOS using HTTPS is not supported through ONIE.
The OcNOS Installation Guide also covers procedures for upgrading existing OcNOS installations by either:
|
•
|
Installing a new OcNOS version over an existing OcNOS version saves the existing configuration files. |
|
•
|
Installing a fresh OcNOS version is destructive and removes existing configuration files, SSH keys, and trial licenses. Users must manually restore these items from backups as needed. |
