When a GRE tunnel is configured, and a GRE-encapped MPLS packet arrives on decap-groups, the traffic-class is derived based on the packet outer DSCP value. This feature aims to allow the user to derive the traffic-class based on the MPLS traffic-class from the payload of the IPv4 GRE packet, using the existing MPLS-exp to TC mapping defined in global QoS maps.
