Points to an entry in the diffServQTable to indicate the queue that a drop algorithm is to monitor when deciding whether to drop a packet. If the row pointed to does not exist, the algorithmic dropper element is considered inactive.

Setting this to point to a target that does not exist results in an inconsistentValue error. If the row pointed to is removed or becomes inactive by other means, the treatment is as if this attribute contains a value of zeroDotZero.
