Processing order for MLS QOS commands

[jacowen]

Based on this config, what would be the QoS values assigned to a packet originating from a directly connected IP Phone?

class-map match-any VOICE

match access-group 170

!

policy-map VOICE-EDGE

class VOICE

set ip dscp 46

!

interface fa0/1

service-policy input VOICE-EDGE

mls qos cos 3

!

access-list 170 permit ip any any

I am mainly wondering if the packet will be assigned a COS of 3 or a DSCP of 46 (EF) or both? I just came into a new environment and am trying to figure what was done and possibly how to improve it. Thanks.

Hi,

It seems little bit strange because all of the IP packet (Both Voice and Data) coming into fa0/1 will be setted to dscp 46.

COS is for layer 2 and DSCP is for layer 3, so, I think both of them will be assigned.

Thanks,
