Hi, I am looking for detailed information on what this command does and how to use it. I have found bits and pieces here and there with google searches but nothing substantial. Does anyone know where I can get detailed information on it?
The commands I am specifically interested in are wrr-queue bandwidth and wrr-queue cos-map.
Thanks in advance.

Because on 6500 device you have 2 threshold levels for the same queue:
wrr-queue cos-map 1 1 1
wrr-queue cos-map 1 2 0
=
queue 1 threshold 1 cos 1
queue 1 threshold 2 cos 0
for more infos:

Thank you both for your help.
asingh, in regards to your post in the other conversation, that person had the following setup:
interface FastEthernet4/41
switchport
switchport access vlan 50
switchport mode access
switchport voice vlan 250
no ip address
wrr-queue cos-map 1 1 1
wrr-queue cos-map 1 2 0
wrr-queue cos-map 2 1 2 3 4 6 7
wrr-queue cos-map 2 2 5
mls qos trust cos
spanning-tree portfast
How/why would he have two separate cos-maps for queue 1 and queue 2 on the one interface?
