[USG Flex H] - Secondary boot image

Maverick87

Hello,

I've discovered that is possible enable, via CLI, a secondary boot image.

My idea is to enable directly the secondary image without enter commands into CLI.

A secondary boot image can be used to switch between firmware images without re-apply the firmware upgrade process.

For example:

• Image1: Previous Firmware
• Image2: Current Firmware

And in this configuration we can choice where to apply next upgrades and maintain always a previous version of the firmware in any case or urgency that somewhat not work in the new firmware.

Yup should be enabled by default if you follow how to enable it you get what you want.

Yes, but my idea is to enable the functionality by default without using CLI to enable it

It is actually pretty funny that most of switches (eg GS/XGS series) has this feature by default, while firmware updates are far less frequent. While ngfws with much more functionality embedded and more frequent updates need cli intervention to achieve it. Where the logic is only Zyxel knows (maybe).
