Dual Image Management Commands
SFTOS software, starting with version 2.5.1, supports a dual image feature that allows the switch to
have two software images in the permanent storage. You can specify which image is the active image
to be loaded in subsequent reboots. This feature helps to reduce down-time when you upgrade or
downgrade the software.
The following commands are in this section:
• boot system on page 119
• delete (software image) on page 120
• filedescr (software image) on page 120
• show bootvar on page 121
• update bootcode on page 122
boot system
This command selects an SFTOS software image to be the active image for subsequent reboots and to
be loaded by the boot loader. The current active image is marked as the backup image for subsequent
reboots.
Syntax
boot system [unit] {image1 | image2}
Parameters
Default
all units in the stack
Mode
Privileged Exec
Command
History
inlinepower Enable or disable PoE for the switch.
inlinepower threshold Set the percentage of the PoE power that could be made available.
show inlinepower (stack) Display summary PoE information for each unit in the stack.
Note: All commands in this section depend on the association made by the copy command
during the download of a particular SFTOS file and a system image identifier of either
“image1” or “image2”. See copy on page 106.
unit
(OPTIONAL) This parameter is valid only on stacks. An error is returned if a
number is entered on a standalone system. In a stack, the parameter identifies the
stack member on which this command must be executed. Default: all units in the
stack
image1 | image2
Identify the software image to become the active image for subsequent reboots. If
the specified image does not exist on the system, this command returns an error.
For details, see the Upgrading Software in a Stack section of the Getting Started
chapter in SFTOS Configuration Guide.
