SFTOS Version 2.5.1 provides several new or revised software management commands: 
The syntax statements for the commands in the Dual Image Management feature are in the System 
Configuration chapter of the SFTOS Command Reference.
Note that the association of a particular SFTOS file name with either “
image1” or “image2” in the copy 
command, above, sets the association that is used by all other commands that use the 
image1 and image2 
keywords. 
For example, if the currently running software image is associated with 
image1, then you then download a 
new image as 
image1, a reload that boots image1 will boot that new image.
Command Syntax Command Mode Usage
boot system
 [unit] {image1 | 
image2}
Privileged Exec Activate a particular image on the target system (“activate”, 
here, means to identify, to the system, the software to install 
on the next reboot).
copy tftp://tftp_server_ip_address/
path/filename {
image1 | image2}
Privileged Exec The system image download command revised for SFTOS 
2.5.1. (Previous to 2.5.1, the command was copy tftp://
tftp_server_ip_address/path/filename system:image.)
copy {image1 | image2} unit://
unit/{image1 | image2}
Privileged Exec Copy a selected software image from the management 
switch to selected switches.
delete
 [unit] {image1 | image2}
Privileged Exec Delete a specified software image.
filedescr [unit] {image1 | 
image2} text-description
Privileged Exec
Adds a name to the image associated with “image1” or 
“
image2”. The name shows up as the SNMP trap receiver 
name and in the output of the show bootvar command. The 
maximum length is 16 case-sensitive alphanumeric 
characters, with no spaces.
reload [unit]
Privileged Exec Reboots the selected stack member. When unit is not 
specified, all stack members are rebooted.
show bootvar [unit]
Privileged Exec Display version information and activation status for the 
current active and backup images on the specified stack 
member. If you do not specify a unit number, the command 
displays image details for all nodes on the stack.
update bootcode [unit]
Privileged Exec Update the bootcode (boot loader) on the designated switch. 
(The bootcode is read from the active image for subsequent 
reboots).
Note: The following parameter definitions apply to the commands provided by the Dual Image 
Management feature:
• unit — the stack member number; only used for stacks. Not specifying a number causes all 
stack members to be affected by the command.
• image1 and image2 — the two possible stored software images. Use the copy command to set 
the association between a particular SFTOS file and the keywords image1 or image2.
