Table 17 lists the severity
levels that you can specify in configuration statements at the [edit system syslog] hierarchy level. The levels from emergency through info are in order from highest severity (greatest
effect on functioning) to lowest.
Unlike the other severity levels, the none level disables logging of a facility instead of indicating how seriously
a triggering event affects routing functions. For more information,
see Disabling the System Logging of a Facility.
