I have configured the Qos on my Core switch (C3750E Software (C3750E-UNIVERSALK9-M), Version 12.2(44)SE1) and I have notified that when MLS QOS is activate on the Core then it's not possible to match EF DSCP packet on my input policyp-map located on my WAN Router.

But when I remove the MLS QOS then I can match the EF DSCP packets, why ?

Thanks in advance for your helps ;)
