Chapter 31 Configuring PFC QoS
To configure filtering in a class map, perform one of these tasks:
Command
Router(config-cmap)# match access-group name
acl_index_or_name
Router(config-cmap)# no match access-group name
acl_index_or_name
Router (config-cmap)# match ip precedence ipp_value1
[ipp_value2 [ipp_valueN]]
Router (config-cmap)# no match ip precedence
ipp_value1 [ipp_value2 [ipp_valueN]]
Router (config-cmap)# match ip dscp dscp_value1
[dscp_value2 [dscp_valueN]]
Router (config-cmap)# no match ip dscp dscp_value1
[dscp_value2 [dscp_valueN]]

Router (config-cmap)# end
Step 2
Router# show class-map class_name

With an MSFC2, Release 12.1(13)E and later releases support the match protocol class 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
match protocol class map command except for traffic being processed in software on the MSFC.
PFC QoS supports class maps that contain a single match command.
PFC QoS does not support the match cos, match any, match classmap, match
destination-address, match input-interface, match mpls, match qos-group, and match
source-address class map commands.
Catalyst 6500 series switches do not detect the use of unsupported commands until you attach a
policy map to an interface (see the
