To export Junos configuration in display set format, the CLI command can be used:

show configuration | display set | save <filename>

Saving the configuration to a file prevents terminal errors or formatting issues compared to the often-used CLI command "show configuration | display set" and log the terminal output - this is especially valid for extensive configuration.

EXPORT CONFIGURATION:
1. Example for exporting Junos configuration in display-set format:

{primary:node0}
user1@host1> show configuration | display set | save vsrx3-1_display-set.conf
Wrote 59 lines of output to 'vsrx3-1_display-set.conf'

2. You can specify the file location as well by indicating the path preceding the filename for

ex.: show configuration | display set | save /var/tmp/vsrx3-1_display-set.conf

The file location is by default /var/home/<user> in this example it's /var/home/labroot/:

{primary:node0}
user1@host1> file list
/var/home/labroot/:
vsrx3-1_display-set.conf

IMPORT CONFIGURATION:

If the configuration file was edited, it can be loaded back from the "set" format in the following way using the CLI command "load set <filename>":

{primary:node0}
user1@host1> configure

{primary:node0}[edit]
user1@host1# load set vsrx3-1_display-set.conf
load complete

CHECK:
