Beginning in privileged EXEC mode, follow these steps to create a hierarchical policy map:
Command
Step 1
configure terminal
Step 2 class-map [match-all | match-any]
class-map-name
Step 3
match {access-group acl-index-or-name |
ip dscp dscp-list | ip precedence
ip-precedence-list}
Step 4
exit

The hierarchical policy map is attached to the SVI and affects all traffic belonging to the VLAN.
The actions specified in the VLAN-level policy map affect the traffic belonging to the SVI. The
police action on the port-level policy map affects the ingress traffic on the affected physical
interfaces.
When configuring a hierarchical policy map on trunk ports, the VLAN ranges must not overlap. If
the ranges overlap, the actions specified in the policy map affect the incoming and outgoing traffic
on the overlapped VLANs.
Aggregate policers are not supported in hierarchical policy maps.
When VLAN-based QoS is enabled, the switch supports VLAN-based features, such as the VLAN
map.
You can configure a hierarchical policy map only on the primary VLAN of a private VLAN.
Purpose
Enter global configuration mode.
Create a VLAN-level class map, and enter class-map configuration
mode. For information about creating a class map, see the
Traffic by Using Class Maps" section on page
By default, no class maps are defined.
(Optional) Use the match-all keyword to perform a logical-AND
•
of all matching statements under this class map. All match criteria
in the class map must be matched.
• (Optional) Use the match-any keyword to perform a logical-OR of
all matching statements under this class map. One or more match
criteria must be matched.
For class-map-name, specify the name of the class map.
•
If neither the match-all or match-any keyword is specified, the default
is match-all.
Note Because only one match command per class map is supported,
the match-all and match-any keywords function the same.
Define the match criterion to classify traffic.
By default, no match criterion is defined.
Only one match criterion per class map is supported, and only one ACL
per class map is supported.
For access-group acl-index-or-name, specify the number or name
•
of the ACL.
For ip dscp dscp-list, enter a list of up to eight IP DSCP values to
•
match against incoming packets. Separate each value with a space.
The range is 0 to 63.
• For ip precedence ip-precedence-list, enter a list of up to eight
IP-precedence values to match against incoming packets. Separate
each value with a space. The range is 0 to 7.
Return to class-map configuration mode.
