Cat3560 and Trust DSCP Question

Hello,

we have several Cat3560 (IOS12.2.20SE4)as pure Layer-2 Switches in use. At these Switches are IP-Phones via a dot1q trunk connected (cisco and non-cisco Phones). The phones mark their traffic with COS=5 and DSCP=46.

Is it possible to configure a "mls qos trust dscp" at the switch-interfaces with IP-Phones, when the switchports are configured as Layer-2?

Of course the switches should also be able to put the traffic in the different receive and transmit-queues based on the received dscp-value.

We'd like configure QoS over our whole campus area DCSP-based and not CoS based to avoid the effort with the CoS<->DSCP mappings.

Thanks

HL
