PFC QoS processes both unicast and multicast traffic.
Note
Enabling PFC QoS Globally
To enable PFC QoS globally, perform this task:
Command
Step 1
Router(config)# mls qos
Router(config)# no mls qos
Step 2
Router(config)# end
Step 3
Router# show mls qos [ipv6]
This example shows how to enable PFC QoS globally:
Router# configure terminal
Router(config)# mls qos
Router(config)# end
Router#
This example shows how to verify the configuration:
Router# show mls qos
QoS is enabled globally
Microflow QoS is enabled globally
