Why each option
The `help reference` command in Junos OS provides concise information about command syntax, option definitions, and default values.
The `help reference` command is designed to offer quick, summary information about Junos OS commands, including their parameters, default settings, and a brief description of their function. This is useful for understanding a command's basic usage without needing full man page details.
Serial and version numbers are typically obtained using commands like `show version` or `show chassis hardware`, not `help reference`.
Active hardware alarms are viewed using commands such as `show chassis alarms`, not `help reference`.
The current configuration in operational mode is viewed using `show configuration` or `show | display set`, not `help reference`.
