Configuring PFC QoS
Enabling Queueing-Only Mode
To enable queueing-only mode on the router, 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

Enabling Microflow Policing of Bridged Traffic
With a PFC2, to apply microflow policing to multicast traffic, you must enter the mls qos bridged
Note
command on the Layer 3 multicast ingress interfaces.
By default, microflow policers affect only routed traffic. To enable microflow policing of bridged traffic
on specified VLANs, perform this task:
Command
Step 1
Router(config)# interface {{vlan vlan_ID } |
1
{ type
slot/port }}
Step 2
Router(config-if)# mls qos bridged
Router(config-if)# no mls qos bridged
Step 3
Router(config-if)# end
Step 4
Router# show mls qos

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

Enables queueing-only mode on the router.
Disables PFC QoS globally on the router.
You cannot disable queueing-only mode
Note
separately.
Exits configuration mode.
Verifies the configuration.
Purpose
Selects the interface to configure.
Enables microflow policing of bridged traffic, including
