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  backup-attribute command to configure an app file of the fabric or of a 
device in the fabric to be with the backup attribute. The app file specified by this command becomes the 
backup startup file when the device starts up next time. When the main startup file is unavailable, the 
backup startup file is used to start the switch. 
If you execute the boot  boot-loader  backup-attribute 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 backup.bin to be the backup startup file of the fabric. 
<Sysname> boot boot-loader backup-attribute backup.bin fabric 
 Set boot file backup-attribute successfully on unit 1! 
 Set boot file backup-attribute successfully on unit 2!
