Viewing the Current Boot Stack
The StarOS image filename scheme changed with release 16.1. Pre-16.1, format = "production.image.bin".
Important
For 16.1 onwards, format = "asr5500-image_number.bin". This change is reflected in the examples provided
below.
Example 1 – StarOS releases prior to 16.1:
boot system priority 18 \
image /flash/15-0-builds/production.45666.bin \
config /flash/general_config.cfg
boot system priority 19 \
image /flash/15-0-builds/production.45717.bin \
config /flash/general_config_3819.cfg
boot system priority 20 \
image /flash/15-0-builds/production.45069.bin \
config /flash/general_config_3665.cfg
Example 2 – StarOS release 16.1 onwards:
boot system priority 18 \
image /flash/16-1-builds/asr5500-16.1.3.bin \
config /flash/general_config.cfg
boot system priority 19 \
image /flash/16-1-builds/asr5500-16.1.1.bin \
config /flash/general_config_3819.cfg
boot system priority 20 \
image /flash/16-1-builds/asr5500-16.1.0.bin \
config /flash/general_config_3665.cfg
The example below shows the output for a combination network booting and local booting configuration.
Notice in this example that the first two boot stack entries (Priorities 18 and 19) load the image file (operating
system software) from an external network server using the Trivial File Transfer Protocol (TFTP), while all
configuration files are located on the /flash device.
Also notice the boot network interface and boot network configuration commands located at the top of the
boot stack. These commands define what MIO/UMIO remote management LAN interface(s) to use and
information about communicating with the external network server that hosts the operating system software
image file.

To identify the boot image priority that was loaded at the initial boot time enter:
show boot initial-config
The example below displays the output:
