Hi Mohammad,

Your configuration suggests that  VLAN 1700 is an MPLS link, is that right?

Are you using any service-policy on the interface facing CE?
Even with no QOS policy facing CE I think the TOS values  should be automatically reflected in MPLS EXP values by default.
But maybe on the CE facing interface you need to have "mls qos trust dscp" for that to happen.
