This example shows how to create a class map that applies to both IPv4 and IPv6 traffic:
Switch(config)# ip access-list 101 permit ip any any
Switch(config)# ipv6 access-list
ipv6-any permit ip any any
Switch(config)# Class-map cm-1
Switch(config-cmap)# match access
-group 101
Switch(config-cmap)# exit
Switch(config)# Class-map cm-2
Switch(config-cmap)# match access
-group name ipv6-any
Switch(config-cmap)# exit
Switch(config)# Policy-map pm1
Switch(config-pmap)# class cm-1
Switch(config-pmap-c)# set dscp 4
Switch(config-pmap-c)# exit
Switch(config-pmap)# class cm-2
Switch(config-pmap-c)# set dscp 6
Switch(config-pmap-c)# exit
Switch(config-pmap)# exit

Classifying, Policing, and Marking Traffic on SVIs by Using Hierarchical Policy Maps
You can configure hierarchical policy maps on SVIs, but not on other types of interfaces. Hierarchical
policing combines the VLAN- and interface-level policy maps to create a single policy map.
On an SVI, the VLAN-level policy map specifies whic
h traffic class to act on. Actions can include
trusting the CoS, DSCP, or IP precedence values or setting a specific DSCP or IP precedence value in
the traffic class. Use the interface-level policy map to specify the physical ports that are affected by
individual policers.
Beginning with Cisco IOS Release 12.2(52)SE, you can configure hierarchic
al policy maps that filter
IPv4 and IPv6 traffic.
Follow these guidelines when configuring hierarchical policy maps:
• Before configuring a hierarchical policy map, you must enable VLAN-based QoS on the physical
ports that are to be specified at the interface level of the policy map.
• You can attach only one policy map per ingress port or SVI.
• A policy map can contain multiple class statements, each with different match criteria and actions.
• A separate policy-map class can exist for each type of traffic received on the SVI.
