This PmTcaIntProfCfgAttrs bitmap reports, bit by bit, which of the optional threshold-configuration attributes in this profile row are actually active, per its DESCRIPTION; it is populated automatically from whichever attributes were successfully set (or later unset) rather than being something an operator sets directly. Because several threshold features (Adjustment, Overflow, Underflow, Alert) in this same profile row can each be configured independently, this bitmap is the fast way to check which subset of them is actually live on a given profile without individually reading every one of the AdjustmentInterval/OverflowThreshold/UnderflowThreshold/AlertInterval objects and checking each for a nonzero value. For example, a profile whose bitmap shows only the Overflow-related bits set tells you that Adjustment TCA and Alert TCA are both dormant on that profile even though the objects for them still exist and return zero.
