Chapter 41 Configuring PFC QoS
Configuring PFC QoS
cannot support ingress CoS mutation, the configuration fails on the first EtherChannel. If the
configuration originated on a nonmember port in a port group that has a member port of the first
EtherChannel, the configuration fails on the nonmember port.
–
The ingress CoS mutation configuration propagates without limit through port groups, member
ports, and port-channel interfaces, regardless of whether or not the ports are configured to trust
CoS or are configured as IEEE 802.1Q tunnel ports.
•
An EtherChannel where you want to configure ingress CoS mutation must not have member ports
that are in port groups containing member ports of other EtherChannels that have member ports that
do not support ingress CoS mutation. (This restriction extends without limit through all
port-group-linked member ports and port-channel-interface-linked ports.)
•
A port where you want to configure ingress CoS mutation must not be in a port group that has a
member port of an EtherChannel that has members that do not support ingress CoS mutation. (This
restriction extends without limit through all port-group-linked member ports and
port-channel-interface-linked ports.)
•
There can be only be one ingress CoS mutation configuration applied to all port-group-linked
member ports and port-channel-interface-linked ports.
Configuring Ingress CoS Mutation Maps
To configure an ingress CoS mutation map, perform this task:
This example shows how to configure a CoS mutation map named testmap:
Router#
configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
mls qos map cos-mutation testmap 4 5 6 7 0 1 2 3
Router(config)#
end
Router#
This example shows how to verify the map configuration:
Router(config)#
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
Router#
Command
Purpose
Step 1
Router(config)#
mls qos map cos-mutation
mutation_map_name mutated_cos1 mutated_cos2
mutated_cos3 mutated_cos4 mutated_cos5
mutated_cos6 mutated_cos7 mutated_cos8
Configures an ingress CoS mutation map. You must enter
8 mutated CoS values to which PFC QoS maps ingress
CoS values 0 through 7.
Router(config)#
no mls qos map cos-mutation
map_name
Deletes the named map.
Step 2
Router(config)#
end
Exits configuration mode.
Step 3
Router#
show mls qos maps cos-mutation
Verifies the configuration.
