Yes,

cos-dscp - Looks at the 3 Class of Service bits on the Layer 2 header and maps that to the 6 bits in the DSCP. Note: CoS bits will be found in frames that are on trunk links (802.1q, ISL).

ip-prec-dscp - Looks at the 3 IP Precedence bits in the Layer 3 header and maps that to the 6 bits in the DSCP.
