System Logging Severity Levels for SNMP Traps
For some traps, when a trap condition occurs, regardless of whether the SNMP agent sends a trap to an NMS, the trap is logged if the system logging is configured to log an event with that system logging severity level. For more information about system logging severity levels, see the JUNOS System Basics Configuration Guide.
