Configuring PFC QoS
This example shows how to attach the ingress CoS mutation map named testmap to Gigabit Ethernet
port 1/1:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# interface gigabitethernet 1/1
Router(config-if)# mls qos cos-mutation testmap
Router(config-if)# end
Router# show mls qos maps cos-mutation
COS mutation map testmap
cos-in : 0 1 2 3 4 5 6 7
------------------------------------
cos-out : 4 5 6 7 0 1 2 3
testmap is attached on the following interfaces

Configuring DSCP Value Maps
These sections describe how DSCP values are mapped to other values:

• Configuring DSCP Markdown Values, page 42-87

Mapping Received CoS Values to Internal DSCP Values
To configure the mapping of received CoS values to the DSCP value that PFC QoS uses internally on the
PFC, perform this task:
This example shows how to configure the received CoS to internal DSCP map:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# mls qos map cos-dscp 0 1 2 3 4 5 6 7
Router(config)# end
Router#
Command Purpose
Step 1
Router(config)# mls qos map cos-dscp dscp1 dscp2
dscp3 dscp4 dscp5 dscp6 dscp7 dscp8
Configures the received CoS to internal DSCP map. You
must enter 8 DSCP values to which PFC QoS maps CoS
values 0 through 7.
Router(config)# no mls qos map cos-dscp
Reverts to the default map.
Step 2
Router(config)# end
Exits configuration mode.
Step 3
Router# show mls qos maps
Verifies the configuration.
