SW1: When STP is never enabled, that is, when the device starts, it is "undo stp enable", and the STP process has never been created, it will display "STP is not configured."
SW2: As long as it is enabled once, the STP process has been created. Once the STP process starts, it will not exit, even if it is turned off again, it will still display the status of STP.
The device operates normally and does not require attention to the processing mechanism.
