Configuring the Boot Stack
The boot stack consists of a prioritized listing of StarOS image-to-CLI configuration file associations. These
associations determine which StarOS image and configuration file gets loaded during StarOS startup or upon a reload or
reboot. Though multiple associations can be configured, StarOS uses the association with the highest priority.
associations determine which StarOS image and configuration file gets loaded during StarOS startup or upon a reload or
reboot. Though multiple associations can be configured, StarOS uses the association with the highest priority.
In the event that there is an error processing this association (for example, one of the files cannot be located), StarOS
attempts to use the association with the next highest priority. Priorities range from 1 to 100, with 1 being the highest
priority. The maximum number of boot stack entries that may be configured in the boot.sys file is 10.

Local-Boot Method
The local-boot method uses the StarOS image and configuration files stored locally. Upon startup or reboot, StarOS
looks on /flash or /hd-raid for the specific software image and accompanying configuration text file. When using the
local-booting method, you only need to configure boot stack parameters.

Viewing the Current Boot Stack
To view the boot stack entries contained in the boot.sys file run the Exec mode show boot command.
Important:
Operator and inspector-level users can execute the show boot command.
The example below shows the command output for a local booting configuration. Notice that in this example both the
image file (operating system software) and configuration file (CLI commands) are located on the /flash device.
image file (operating system software) and configuration file (CLI commands) are located on the /flash device.
boot system priority 10 \
image /flash/staros.bin \
config /flash/system.cfg
To identify the boot image priority that was loaded at the initial boot time enter:
[local]host_name# show boot initial-config
The example below displays the output:
Initial (boot time) configuration:
image tftp://192.168.1.161/tftpboot/image_filename.bin \
config /flash/system.cfg
priority 1
