Asr 5000 System Administration Guide, Staros Release 21.1 - Cisco ASR 5000 Administration Manual

Viewing the Current Boot Stack
The examples below shows the command output for a local booting configuration. Notice that in these examples
both the image file (operating system software) and configuration file (CLI commands) are located on the
/flash device.
Important The StarOS image filename scheme changed with release 16.1. Pre-16.1, format = "production.image.bin".
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/asr5000-16.1.3.bin \
config /flash/general_config.cfg
boot system priority 19 \
image /flash/16-1-builds/asr5000-16.1.1.bin \
config /flash/general_config_3819.cfg
boot system priority 20 \
image /flash/16-1-builds/asr5000-16.1.0.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 SPIO management LAN interface(s) to use and information about
communicating with the external network server that hosts the operating system software image file.

boot system priority 19 image tftp://192.168.1.161/tftpboot/
/flash/general_config.cfg
boot system priority 20 image /flash/
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:
[local]
Initial (boot time) configuration:
