Configuring QoS in ME 3400

I have to change of platform of one switch 3550 to and switch ME 3400.

I have to adapt the QoS configuration of the switches 3550 to the new switches ME 3400.

This is the QoS configuration of the 3550 :


mls qos map cos-dscp 10 15 20 25 30 35 40 45

mls qos


interface FastEthernet0/X

mls qos cos 4

mls qos trust cos

wrr-queue bandwidth 1 2 3 4



This is the QoS configuration that I have done in ME 3400:

Is this configuration ok?

service-policy input MARCADO_ENTRADA

ip dhcp snooping trust


I only can apply the service-policy in trunk ports.

How Can I configure a service-policy in a access-port?

When I apply the service-policy input in the fa0/1 and I send traffic I can't see any COS traffic.

Could you help me to configure this??

Why I can see traffic in the interface?
