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:
Gi4/1 Gi4/1.12
Qos trust state is IP Precedence on the following interfaces:
Gi4/2 Gi4/2.42
Vlan or Portchannel(Multi-Earl) policies supported: Yes
Egress policies supported: Yes
----- Module [5] -----
QoS global counters:
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
MPLS packets with EXP changed by policing: 0
Enabling Queueing-Only Mode
To enable queueing-only mode, perform this task:
When you enable queueing-only mode, the router does the following:
• 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.
This example shows how to enable queueing-only mode:
Router# configure terminal
Router(config)# mls qos queueing-only
Router(config)# end
Router#
Command Purpose
Step 1
Router(config)# mls qos queueing-only
Enables queueing-only mode.
Router(config)# no mls qos queueing-only
Disables PFC QoS globally.
Note You cannot disable queueing-only mode
separately.
Step 2
Router(config)# end
Exits configuration mode.
Step 3
Router# show mls qos
Verifies the configuration.
