Configuring PFC QoS
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 (see the
Command
Step 1
Router(config)# mls qos map ip-prec-dscp dscp1
dscp2 dscp3 dscp4 dscp5 dscp6 dscp7 dscp8
Router(config)# no mls qos map ip-prec-dscp
Step 2
Router(config)# end
Step 3
Router# show mls qos maps
This example shows how to configure the received IP precedence to internal DSCP map:
Router# configure terminal
Enter configuration commands, one per line.
Router(config)# mls qos map ip-prec-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 IpPrecedence-dscp map
IpPrecedence-dscp map:
<...Output Truncated...>
Router#
Mapping Internal DSCP Values to Egress CoS Values
To configure the mapping of the DSCP value that PFC QoS uses internally on the PFC to the CoS value
used for egress LAN port scheduling and congestion avoidance (see the
on page 31-17
Command
Step 1
Router(config)# mls qos map dscp-cos dscp1 [dscp2
[dscp3 [dscp4 [dscp5 [dscp6 [dscp7 [dscp8]]]]]]]
to cos_value
Router(config)# no mls qos map dscp-cos
Step 2
Router(config)# end
Step 3
Router# show mls qos maps
When configuring the internal DSCP to egress CoS map, note the following:

You can enter up to 8 DSCP values that PFC QoS maps to a CoS value.
You can enter multiple commands to map additional DSCP values to a CoS value.
You can enter a separate command for each CoS value.

Purpose
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.
Reverts to the default map.
Exits configuration mode.
Verifies the configuration.
