Chapter 41 Configuring PFC QoS
Configuring PFC QoS
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#
This example shows how to verify the configuration:
Router# show mls qos maps | begin Cos-dscp map
Cos-dscp map:
cos: 0 1 2 3 4 5 6 7
----------------------------------
dscp: 0 1 2 3 4 5 6 7

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