Chapter 31 Configuring PFC QoS
Creating a Policy Map Class and Configuring Filtering
Note •
•
•
Policy maps can contain one or more policy map classes. Enter one of these class commands to create a
policy map class and configure filtering in it.
To create a policy map class and configure it to filter with an already defined class map, perform this
task:
Command
Router(config-pmap)# class class_name
Router(config-pmap)# no class class_name
To create a policy map class and a class map simultaneously, perform this task:
Command
Router(config-pmap)# class class_name {access-group
acl_index_or_name | dscp dscp_1 [dscp_2 [dscp_N]] |
precedence ipp_1 [ipp_2 [ipp_N]]}
Router(config-pmap)# no class class_name

With an MSFC2, Release 12.1(13)E and later releases support the class class_name protocol policy
map command, which configures NBAR and sends all traffic on the Layer 3 interface, both ingress
and egress, to be processed in software on the MSFC2. To configure NBAR, refer to this publication:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122t/122t8/dtnbarad.htm
Earlier releases provide PFC QoS and Layer 3 switching in hardware, which prevents support of the
class class_name protocol policy map command except for traffic being processed in software on
the MSFC.
PFC QoS does not support the class class_name destination-address, class class_name
input-interface, class class_name qos-group, and class class_name source-address policy map
commands.
PFC QoS does not detect the use of unsupported commands until you attach a policy map to an
interface (see the "Attaching a Policy Map to an Interface" section on page
Put all trust-state and policing commands for each type of traffic in the same policy map class.
PFC QoS does not attempt to apply commands from more than one policy map class to traffic.

Purpose
Creates a policy map class and configures it to filter with a
class map (see the "Creating a Class Map" section on
page 31-40).
PFC QoS supports class maps that contain a single
Note
match command.
Clears use of the class map.
Purpose
Creates a policy map class and creates a class map and
configures the policy map class to filter with the class map.
This command creates a class map that can be used in
Note
other policy maps.
Clears use of the class map (does not delete the class map).
