Does anyone know what exactly does this do? Why/What scenarios would this be used for?
It states:
To disable the user inputs at u-boot, boot loader and Junos Kernel boot stage, use the chassis routing-engine bios command as following:
user@host# set chassis routing-engine bios uninterrupt
If the device boots into loader what happens if this is enabled?
- Can you still reboot the device?
- Can you install Junos from file with usb/tftp/etc?
- Does it auto reboot here if it stops on boot? Seems to be common occurence after upgrades or just a general reboot of the device.
Something of note the documentation give a warning:
On SRX Series devices, if both set system ports console insecure and set chassis routing-engine bios uninterrupt options are configured, there is no alternative recovery method available in case Junos OS fails to boot and the device might become unusable.
