Description: This persistent variable indicates the desired severity level for sending a generated SNMP trap based upon this severity level. This control variable thus acts as a severity level filter.

'critical' is the highest severity level, followed in decreasing order by 'major', 'minor', 'warning', and 'normal', which is the lowest severity level.

Specifying a severity level with this variable indicates that SNMP traps of that level and higher and traps not controlled by a severity filter will be sent when generated, unless limited by 'trapControl', 'trapFlow', 'trapMgrControl' or enable/disable variables for specific traps.

Setting this variable to 'critical' is the most restrictive. Only SNMP traps with a severity level of critical, or that do not use a severity level will be sent when generated unless limited by other filters.

Setting this variable to 'normal' allows all SNMP traps that are generated to be sent unless limited by other filters.

The default value for this variable is 'normal'.

The Agent determines if a trap can be sent by examining several controls (or filters), all of which enable the sending of the trap. These are described in their order of checking below:

One, the MIB variable that enables that specific trap to be sent is enabled. (Each trap can be selectively enabled or disabled.) If a trap is not sent due to this filter, then 'trapFilteredSpecific' is incremented.

Two, the MIB 'trapControl', is set to 'unLimited'; or, it is set to 'feedbackPinLimited' and 'trapFlow' is set to 'open'. If a trap is not sent due to this filter, then 'trapFilteredControl' is incremented.

Three, one or more trap managers must be defined in the table 'trapMgrTable' with a valid IP address in 'trapMgrTable.trapMgrAddress', and their control variable 'trapMgrTable.trapMgrControl' must be configured to 1) 'both' or 'standard' and the trap is a standard trap; or 2) 'enterprise' or 'both', and the trap is an enterprise trap. If a trap is not sent due to this filter, then 'trapFilteredManager' is incremented.

Four, the trap has no associated severity level, or the severity level of the trap is equal or higher than the value specified by the severity filter 'trapSeverityFilter'. If a trap is not sent due to this filter, then 'trapFilteredSeverity' is incremented.
