Enabling PFC QoS Globally
To enable PFC QoS globally, perform this task:
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
QoS global counters:
Total packets: 544393
Command
Purpose
Step 1
Router(config)#
mls qos
Enables PFC QoS globally on the router.
Router(config)#
no mls qos
Disables PFC QoS globally on the router.
Step 2
Router(config)#
end
Exits configuration mode.
Step 3
Router#
show mls qos
[
ipv6
]
Verifies the configuration.
