1.3.6.1.4.1.171.12.1.2.9.2
Indicates the level of trap severity control. The system has a severity level control and each trap should have a severity control set. When trap events occur and its severity is higher than the system severity control level, the trap works as defined. If the event severity is lower than the system severity control level, the event is ignored as if it did not occur.
