QoS Error on 3724

Hi,

I am setting up QoS between 2 sites with the following configuration on the local 3724. I am creating a new cos-dscp map (due to our PBX config), then as follows:

#mls qos

#mls qos map cos-dscp 0 8 16 26 34 46 48 56

#access-list 100 permit ip any any

#Class-map VOIP

#Match access-group 100

#Policy Map VOIP-Fair

#Class VOIP

#interface fast 1/0/x

#mls qos trust cos

#Service Policy input VOIP-Fair

Once I try and apply the final command I receive the following error:

"Service Policy attachment failed"

Does anyone know why this would happen? I can't find the error anywhere in CCO.

TIA.

Re: QoS Error on 3724

What action is defined within Policy VOIP-Fair for traffic that matches class VOIP?

Keep in mind, the cos-dcsp map only defines the internal DSCP value.
