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
IP shortcut packets: 1410
Packets dropped by policing: 0
IP packets with TOS changed by policing: 467
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.
