This read-create INTEGER points to a Queue Shape Profile that defines per-queue shaping, or rate limiting of individual egress queues, for this interface. An admin uses this when different queues on the same port need different shaped rates, such as capping a bulk-data queue more tightly than a voice queue on the same interface. For example, an admin wanting to cap a specific low-priority queue's rate separately from the port's overall shaper would set this pointer to a queue shape profile defining that queue's individual limit.
