The NE2552E can re‐mark the DSCP value of ingress packets to a new value, and
set the 802.1p priority value, based on the DSCP value. You can view the settings
by using the following command:
NE2552E(config)# show qos dscp
Current DSCP Remarking Configuration: OFF

Use the following command to turn on DSCP re‐marking globally:
NE2552E(config)# qos dscp re-marking
Then you must enable DSCP re‐marking on any port that you wish to perform this
function.
Note: If an ACL meter is configured for DSCP re‐marking, the meter function
takes precedence over QoS re‐marking.
