Juniper JUNOS OS 10.3 - SYSTEM LOG MESSAGES REFERENCE 7-12-2010 User Manual

Table 6 on page 10 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 Logging of a Facility” on page 24.
