Configuring PFC QoS
This example shows how to configure internal DSCP values 0, 8, 16, 24, 32, 40, 48, and 54 to be mapped
to egress CoS value 0:
Router# configure terminal
Enter configuration commands, one per line.
Router(config)# mls qos map dscp-cos 0 8 16 24 32 40 48 54 to 0
Router(config)# end
Router#
This example shows how to verify the configuration:
Router# show mls qos map | begin Dscp-cos map
Dscp-cos map:
<...Output Truncated...>
Router#
Note In the Dscp-cos display, the CoS values are shown in the body of the matrix; the first digit of the DSCP
value is in the column labeled d1 and the second digit is in the top row. In the example shown, DSCP
values 41 through 47 all map to CoS 05.

markdown_dscp
Router(config)# no mls qos map policed-dscp
{normal-burst | max-burst}
