We've enabled auto qos on our 6504 w/sup32-10G on our ws-6148a blades and are receiving the following errors. Is this normal? Code is the latest out: 12.2(33)SXH2, switches are runnin as L2 devices only (no routing):
Warning: rcv cosmap will not be applied in hardware.
To modify rcv cosmap in hardware, all of the interfaces below
must be put into 'trust cos' state:
Gi3/1 Gi3/2 Gi3/3 Gi3/4 Gi3/5 Gi3/6 Gi3/7 Gi3/8 Gi3/9 Gi3/10 Gi3/11 Gi3/12 Gi3/13 Gi3/14 Gi3/15 Gi3/16 Gi3/17 Gi3/18 Gi3/19 Gi3/20 Gi3/21 Gi3/22 Gi3/23 Gi3/24 Gi3/25 Gi3/26 Gi3/27 Gi3/28 Gi3/29 Gi3/30 Gi3/31 Gi3/32 Gi3/33 Gi3/34 Gi3/35 Gi3/36 Gi3/37 Gi3/38 Gi3/39 Gi3/40 Gi3/41 Gi3/42 Gi3/43 Gi3/44 Gi3/45 Gi3/46 Gi3/47 Gi3/48
threshold configured on all 48 ports on slot 3.
Should config changes be made to the cos trust to utilize hardware capabilities?
Thanks,

Use the "Interface Range" command and try to disable it on all the interfaces on the module.
By default, you should not see the "rcv-queue .." configurations under the interface. In order to remove the configuration,
try the following commands.
Interface range Gi1/1 - 1/12
Mls qos trust cos
No rcv-queue cos-map
No mls qos trust cos

Thanks for the suggestion. Below are the current port configuration for an auto qos port with pc/phone, as well as the commands I tried on a set of selective interfaces (G3/1 -2). I get an error regarding the asic. Since we have phone ports requiring auto qos voip cisco-phone intermixed (non sequential) with access only ports (printers, scanners, etc), this may present a problem on the 6500's.
This problem does not exist on the 4500 series chassis. :-/
