DSCP Re-marking and Mapping
The GbESM 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 default settings by using
the cfg/qos/dscp/cur command, as shown below.
Use the cfg/qos/dscp/on command to turn on DSCP re-marking globally. Then you must
enable DSCP re-marking (cfg/port x/dscpmrk/ena) on any port that you wish to per-
form this function.
NOTE – If an ACL meter is configured for DSCP re-marking, the meter function takes prece-
dence over QoS re-marking.
