Traps flow through two levels of filtering: severity of a particular trap category and trap destination. If the severity of a particular category is not defined, global trap severity is used for computation. The value of this object defines trap-category based minimum severity level, a trap must have in order to be forwarded for the destination level trap filtering. A trap will be discarded and counted in juniSnmpTrapGlobalDiscards if its severity level is less than the value of this object. For security reasons, �Mirror� category will not be allowed to be configured through SNMP. Only those trap categories which are configured using per category based trap severity filter are displayed as part of this table. If the value of juniSnmpTrapGlobalSeverityFilter is modified, it will overwrite all the values specified in this table.
