Translation between 3750 and 6500 QOS config

We have a new 3750 layer 3 switch installed for a VOIP project. It has the QOS configured, and I need to configure our existing 6513. The 3750 is running 12.4 and the 6513 is running 12.2(17r)SX3. Can someone please help translate the QOS from the 3750 for the 6513? I am not familiar with the QOS configurations (obviously), but I am doing some reading trying to figure this out.

Translation between 3750 and 6500 QOS config

I found documentation which indicated to add auto qos to each interface. I then added the following to each interface:

auto qos voip trust

mls qos trust dscp

It added configs for COS queuing, but I can't seem to find the DSCP queuing commands. Do I need to tweak the default commands?

wrr-queue bandwidth 50 255

wrr-queue queue-limit 75 15

wrr-queue random-detect min-threshold 2 70 100

wrr-queue random-detect max-threshold 2 90 100

wrr-queue cos-map 1 2 0

wrr-queue cos-map 2 1 1 2 3 4

wrr-queue cos-map 2 2 6 7

rcv-queue cos-map 1 1 0

rcv-queue cos-map 1 3 1 2 3 4

rcv-queue cos-map 1 4 6 7

mls qos trust dscp

auto qos voip trust

What would be the commands (if any) for the DSCP items?
