Priority Commands (Layer 3 and 4)
qos map phb-queue
This command determines the hardware output queues to use based on the internal per-hop
behavior value. Use the no form to restore the default settings.
Syntax
qos map phb-queue queue-id from phb0 ... phb7
no map phb-queue phb0 ... phb7
phb - Per-hop behavior, or the priority used for this router hop. (Range: 0-7)
queue-id - The ID of the priority queue. (Range: 0-7, where 7 is the highest priority queue)
