The value of tmnxMcPathChassisRRInactiveRec specifies whether
initially inactive multicast records use the IOM default secondary
multicast path or not.
If the value of tmnxMcPathChassisRRInactiveRec is 'true' the system
redistributes newly populated inactive records among all available
IOM multicast paths and multicast switch fabric planes.
If the value of tmnxMcPathChassisRRInactiveRec is 'false' the system
continues to set all initially inactive multicast records to use
the IOM default secondary multicast path.
