Configuring PFC QoS
This example shows how to map DSCP 1 to marked-down DSCP value 0:
Router# configure terminal
Enter configuration commands, one per line.
Router(config)# mls qos map policed-dscp normal-burst 1 to 0
Router(config)# end
Router#
This example shows how to verify the configuration:
Router# show mls qos map
Normal Burst Policed-dscp map:
Maximum Burst Policed-dscp map:
<...Output Truncated...>
Router#
In the Policed-dscp displays, the marked-down DSCP values are shown in the body of the matrix; the
Note
first digit of the original DSCP value is in the column labeled d1 and the second digit is in the top row.
In the example shown, DSCP 41 maps to DSCP 41.
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, perform this task:
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
