Parameter
primary: Specifies an application as primary boot application.
backup: Specifies an application as backup boot application.
file-url: Path + name of an APP file in the Flash memory.
Description
Use the boot boot-loader command to specify the APP file that will be adopted when
the switch reboots next time.
You can use this command to specify a primary and backup boot application for a
switch. The boot process is as following:
z Normally, primary boot application is adopted for boot.
z When the primary boot application goes wrong, the switch automatically uses the
backup boot application to startup.
z If the switch can not boot through primary and backup boot applications, it
chooses an application in the Flash randomly for boot. If the switch still can not
boot, then the switch fails to boot.
The BootROM with the version not below 400 supports double applications boot.
Example
# Specify the S7750.APP as the primary application adopted when the switch reboots
next time.
