Configuration Examples for QoS
--------------------------------
This example shows how to modify and display the IP-precedence-to-DSCP map:
Switch(config)# mls qos map ip-prec-dscp 10 15 20 25 30 35 40 45
Switch(config)# end
Switch# show mls qos maps ip-prec-dscp
IpPrecedence-dscp map:
ipprec:
--------------------------------
This example shows how to map DSCP 50 to 57 to a marked-down DSCP value of 0:
Switch(config)# mls qos map policed-dscp 50 51 52 53 54 55 56 57 to 0
Switch(config)# end
Switch# show mls qos maps policed-dscp
Policed-dscp map:

0 :

In this policed-DSCP map, the marked-down DSCP values are shown in the body of the matrix. The d1
Note
column specifies the most-significant digit of the original DSCP; the d2 row specifies the least-significant
digit of the original DSCP. The intersection of the d1 and d2 values provides the marked-down value. For
example, an original DSCP value of 53 corresponds to a marked-down DSCP value of 0.
This example shows how to map DSCP values 0, 8, 16, 24, 32, 40, 48, and 50 to CoS value 0 and to display
the map:
Switch(config)# mls qos map dscp-cos 0 8 16 24 32 40 48 50 to 0
Switch(config)# end
Switch# show mls qos maps dscp-cos

In the above DSCP-to-CoS map, the CoS values are shown in the body of the matrix. The d1 column
Note
specifies the most-significant digit of the DSCP; the d2 row specifies the least-significant digit of the
DSCP. The intersection of the d1 and d2 values provides the CoS value. For example, in the DSCP-to-CoS
map, a DSCP value of 08 corresponds to a CoS value of 0.
