It depends on whether you have classification policies applied and trust status on receiving port.

Here are the different scenarios:

1-Port set to trust DSCP => use DSCP from Packet.

2-Port set to trust COS => use cos to dscp map to obtain DSCP value.

3-no trust configured => use default port DSCP.

4-Traffic matches a class map => use DSCP set by policy.

Internal DSCP derived from the above are then used to place packets into the different outbound Queues.
