When using Junos OS, there are two primary operational modes: configuration mode and operational mode. Configuration mode is used to configure the device's settings and features, while operational mode is used to monitor the device's current status and activity.
When executing operational mode commands from within configuration mode, it's important to include the "run" parameter. This is because configuration mode is used to configure the device's settings, not to monitor its current status. The "run" parameter essentially tells the device to temporarily exit configuration mode and enter operational mode to execute the specified command.
For example, if you were in configuration mode and wanted to check the status of a specific interface, you would need to enter the "run show interfaces ge-0/0/0" command. The "run" parameter tells the device to temporarily exit configuration mode and enter operational mode, while the "show interfaces ge-0/0/0" command tells the device to display information about the specified interface.
It's worth noting that there are other parameters that can be used to execute operational mode commands from within configuration mode, such as "do" and "insert". However, "run" is the most commonly used and widely accepted parameter for this purpose.
