Chapter 31 Configuring PFC QoS
Configuring PFC QoS
– Enter the policed-dscp-transmit keyword to cause all matched out-of-profile traffic to be
marked down as specified in the markdown map (see the “Configuring DSCP Markdown
Values” section on page 31-68).
– For marking without policing, enter the transmit keyword to transmit all matched out-of-profile
traffic.
The violate-action keyword is not supported with the PFC1, but the keyword can be entered with a
PFC1 if the parameters match the exceed-action parameters.
This example shows how to create a named aggregate policer with a 1-Mbps rate limit and a 10-MB burst
size that transmits conforming traffic and marks down out-of-profile traffic:
Router(config)# mls qos aggregate-policer aggr-1 1000000 10000000 conform-action transmit
exceed-action policed-dscp-transmit
Router(config)# end
Router#
This example shows how to verify the configuration:
Router# show mls qos aggregate-policer aggr-1
ag1 1000000 1000000 conform-action transmit exceed-action policed-dscp-transmit AgId=0
[pol4]
Router#
The output displays the following:
• The AgId parameter displays the hardware policer ID.
• The policy maps that use the policer are listed in the square brackets ([]).
Configuring a PFC QoS Policy
These sections describe PFC QoS policy configuration:
• PFC QoS Policy Configuration Overview, page 31-37
• Configuring MAC-Layer Named Access Lists (Optional), page 31-39
• Configuring a Class Map (Optional), page 31-40

• Configuring a Policy Map, page 31-42

• Attaching a Policy Map to an Interface, page 31-49
Note PFC QoS policies process both unicast and multicast traffic.
PFC QoS Policy Configuration Overview
Note To mark traffic without limiting bandwidth utilization, create a policer that uses the transmit keywords
for both conforming and nonconforming traffic.
