confIfCreateObj is an action object that creates a new confIfTable row in one operation, by packing confIfMCRouteProto, confIfIgmpQueryInterval, confIfIgmpRobustness, confIfDvmrpMetric, and confIfDvmrpUnreachableMetric into an 11-byte binary string, per its documented byte layout. An admin, or a management application, uses this to provision a new multicast interface's full DVMRP and IGMP configuration in a single SNMP SET instead of creating the row and then setting five separate objects, and the agent returns genError if the entry already exists. For example, to add a new interface entry with multicast routing enabled, a query interval of 125, robustness of 2, DVMRP metric of 1, and unreachable metric of 31, a management tool would encode those five values into the 11-byte string and SET confIfCreateObj with it.
