Parameters
file-url: Path or the name of the app file in the Flash memory, a string comprising 1 to 64 characters.
fabric: Specifies to apply the configuration to the whole fabric.
Description
Use the boot boot-loader command to configure an app file of the fabric or of a device in the fabric to
be with the main attribute. The app file specified by this command becomes the main startup file when
the device starts up next time.
If you execute the boot boot-loader command without the fabric keyword, the configuration applies to
the local unit only.
Before configuring the main or backup attribute for a file in the fabric, make sure the file already exists
on all devices in the fabric. This is because Ethernet switches do not allows you to specify an app file in
other unit's Flash memory as the app startup file of the local unit.
Examples
# Configure the file boot.bin to be the main startup file of the fabric.
<Sysname> boot boot-loader boot.bin fabric
The specified file will be booted next time on unit 1!
The specified file will be booted next time on unit 2!
