Configuring PFC QoS
This example shows how to map DSCP 30 to mutated DSCP value 8:
Router#
configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
mls qos map dscp-mutation mutmap1 30 to 8
Router(config)#
end
Router#
This example shows how to verify the configuration:
Router#
show mls qos map | begin DSCP mutation
DSCP mutation map mutmap1: (dscp= d1d2)
d1 : d2 0 1 2 3 4 5 6 7 8 9
-------------------------------------
0 : 00 01 02 03 04 05 06 07 08 09
1 : 10 11 12 13 14 15 16 17 18 19
2 : 20 21 22 23 24 25 26 27 28 29
3 : 08 31 32 33 34 35 36 37 38 39
4 : 40 41 42 43 44 45 46 47 48 49
5 : 50 51 52 53 54 55 56 57 58 59
6 : 60 61 62 63

Note
In the DSCP mutation map displays, the marked-down DSCP values are shown in the body of the matrix;
the 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 30 maps to DSCP 08.
Attaching an Egress DSCP Mutation Map to an Interface
To attach an egress DSCP mutation map to an interface, perform this task:
This example shows how to attach the egress DSCP mutation map named mutmap1 to Fast Ethernet
port 5/36:
Router#
configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
interface fastethernet 5/36
Router(config-if)#
mls qos dscp-mutation mutmap1
Router(config-if)#
end
Command
Purpose
Step 1
Router(config)#
interface
{{
vlan
vlan_ID
} |
{
type
1
slot/port
[
.
subinterface
]} |
{
port-channel
number
[
.
subinterface
]}}
1.
type
=
ethernet
,
fastethernet
,
gigabitethernet
, or
tengigabitethernet
Selects the interface to configure.
Step 2
Router(config-if)#
mls qos dscp-mutation
mutation_map_name
Attaches an egress DSCP mutation map to the interface.
Router(config-if)#
no mls qos dscp-mutation
mutation_map_name
Removes the egress DSCP mutation map from the
interface.
Step 3
Router(config-if)#
end
Exits configuration mode.
Step 4
Router#
show running-config interface
{{
vlan
vlan_ID
} | {
type
1
slot/port
} | {
port-channel
number
}}
Verifies the configuration.
