What does the command show configuration system | display set do?

The command "show configuration system | display set" is used in Juniper devices to present the current configuration in a "set" format, which is more concise and easier to read when assessing configuration specifics. This format displays each configuration statement as it is structured in the Junos operating system, which helps users understand the organization of the configuration in a hierarchical way.

In this command, "show configuration system" indicates that you are querying the system configuration, while the pipe symbol "|" is used to pass the output to a subsequent command—in this case, "display set." By using "display set," the output will not only show the configurations but will also format them neatly as individual lines, making it straightforward for users to identify and analyze specific settings.

This command is particularly useful for system administrators who need to quickly verify configurations or for troubleshooting purposes. The set format makes it easier to read and copy configurations as needed.
