This object indicates the average percentage usage of ports
pre-allocated in bulk. This value is valid only if the bulk
allocation is configured. That is the value specified by the
cNatCgnInstanceProtocolPortBulkAllocControl is more than 1.
This value gives hints about effectiveness of bulk port
allocation technique. A very low percentage of bulk port usage
may suggest that, bulk allocation size be reduced. On the other
hand, a value close to 100 may hint at increasing the bulk size
to further reduce log data volume.
