I have been researching about QoS and egress queuing configuration. And i don't fully understand the function of each command. I understand that each interface have a queues (the number depends on the model of the router or switch and also i think you can configure them) and you provision the bandwidth and the thresholds to have a better performance. If it helps the equipment i an working on is a Cisco 7609-S
So i put my comments below of how i think the commands works, and maybe you can correct or help me understand better.

wrr-queue queue-limit 0 0 10 12 25 50 3
!Reserves the buffer space for the ques, 0% for queue 1, 0% for queue 2, 10% for queue 3... and so on..
