Configuring PFC3BXL or PFC3B Mode MPLS QoS
This example shows how to verify the configuration:
Router# show mls qos
QoS is enabled globally
Microflow policing is enabled globally
QoS ip packet dscp rewrite enabled globally
Qos trust state is DSCP on the following interfaces:
Qos trust state is IP Precedence on the following interfaces:
Vlan or Portchannel(Multi-Earl) policies supported: Yes
Egress policies supported: Yes

Enabling Queueing-Only Mode
To enable queueing-only mode, perform this task:
Command
Step 1
Router(config)# mls qos queueing-only
Router(config)# no mls qos queueing-only
Step 2
Router(config)# end
Step 3
Router# show mls qos
When you enable queueing-only mode, the router does the following:
•

This example shows how to enable queueing-only mode:
Router# configure terminal
Router(config)# mls qos queueing-only
Router(config)# end

Total packets: 5957870
IP shortcut packets: 0
Packets dropped by policing: 0
IP packets with TOS changed by policing: 6
IP packets with COS changed by policing: 0
Non-IP packets with COS changed by policing: 3

Disables marking and policing globally
Configures all ports to trust Layer 2 CoS
Note
The router applies the port CoS value to untagged ingress traffic and to traffic that is received
through ports that cannot be configured to trust CoS.
