Auto QOS on 6500 with Sup32-10G gives warning errors

swharvey
Level 3
Level 3

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,

-Scott

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. :-/
