spdRuleDefFilter points to a filter that is used to evaluate whether the action associated with this row is executed or not. The action will only execute if the filter referenced by this object evaluates to TRUE after first applying any negation required by the spdRuleDefFilterNegated object.

The following tables and scalars can be pointed to by this column. All but diffServMultiFieldClfrTable are defined in this MIB. Implementations MAY choose to provide support for other filter tables or scalars as well:

diffServMultiFieldClfrTable

spdIpOffsetFilterTable spdTimeFilterTable spdCompoundFilterTable spdTrueFilter

If this column is set to a VariablePointer value, which references a non-existent row in an otherwise supported table, the inconsistentName exception MUST be returned. If the table or scalar pointed to by the VariablePointer is not supported at all, then an inconsistentValue exception MUST be returned.

If, during packet processing, this column has a value that references a non-existent or non-supported object, the packet MUST be dropped.
