Software Management

This chapter displays all the relevant commands used to manage the system software image.

image boot

	image boot {location <location-id> \| next} Specifies the default location where the system should be booted from.
Syntax Description	location-id	Specifies the default destination location. There can be up to 2 images on the system. Possible values: 1-2.
Syntax Description	next	Sets the boot location to be the next once after the one currently booted from, thus avoiding a cycle through all the available locations
Default	N/A
Configuration Mode	config
History	1.5
Example	Copy Copied! `ufmapl [ mgmt-sa ] (config) # image boot location 2`
Related Commands	show images
Notes

boot next

	boot next fallback-reboot enable no boot next fallback-reboot enable Sets the default setting for next boot. Normally, if the system fails to apply the configuration on startup (after attempting upgrades or downgrades, as appropriate), it will reboot to the other partition as a fallback. The no form of the command tells the system not to do that, only for the next boot.
Syntax Description	N/A
Default	N/A
Configuration Mode	config
History	1.5
Example	Copy Copied! `ufmapl [ mgmt-sa ] (config) # boot fallback-reboot enable`

Notes	Normally, if the system fails to apply the configuration on startup (after attempting upgrades or downgrades, as appropriate), it will reboot to the other partition as a fallback. The 'no' variant of this command tells the system NOT to do that, ONLY for the next boot. Note that this setting is not persistent, and will go back to enabled automatically after every boot.
