show mls qos maps
Use the show mls qos maps user EXEC command to display quality of service (QoS) mapping
information. During classification, QoS uses the mapping tables to represent the priority of the traffic
and to derive a corresponding class of service (CoS) or Differentiated Services Code Point (DSCP) value
from the received CoS, DSCP, or IP precedence value.

Usage Guidelines
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output
do not appear, but the lines that contain Output appear.
The policed-DSCP, DSCP-to-CoS, and the DSCP-to-DSCP-mutation maps appear as a matrix. The d1
column specifies the most-significant digit in the DSCP. The d2 row specifies the least-significant digit
in the DSCP. The intersection of the d1 and d2 values provides the policed-DSCP, the CoS, or the
mutated-DSCP value. For example, in the DSCP-to-CoS map, a DSCP value of 43 corresponds to a CoS
value of 5.
