Configuring VLAN-Group Class Maps

To configure a VLAN-group class map, which creates a VLAN-group traffic class, enter the following
commands beginning in global configuration mode:
Command
Step 1
Router(config)# class-map match-any
class-map-name
Step 2
Router(config-cmap)# match vlan vlanid

Examples

The following example configuration creates a VLAN group named customer1 with VLANs 2, 3, 4, 5,
and 7 as members of the group:
Router> enable
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# class-map match-any customer1
Router(config-cmap)# match vlan 2 3-5 7
Router(config-cmap)# exit

For a VLAN-group policy, you are not required to only attach child policies under the class-default
class of a parent policy. You may apply child policies to the class-default class of another child
policy, the class-default class of a parent policy, or to other classes defined in parent and child
policies.
This applies only to VLAN-group policies. For other QoS policies, you must apply child
Note
policies only to the class-default class of a parent policy.
Do not configure any other QoS actions for a parent class if you apply a child policy to that class.
For a VLAN-group policy, if a class of a parent policy map specifies the service-policy command,
do not configure any other QoS actions for that class.
Configure only the shape command in outbound parent classes of a VLAN-group policy if a child
policy is applied to that class.
Chapter 21
Purpose
Creates or modifies a traffic class. Enters class-map
configuration mode.
(Optional) match-any indicates that if the VLAN ID of a
packet matches any of the specified VLAN IDs, classify the
packet as belonging to the traffic class.
Note The router does not support the match-all keyword
for VLAN-based classification.
class-map-name is the name of the class map. You can
specify the class-default class as the class map name to
configure a traffic class to which the router assigns all of the
traffic that does not match another configured class.
Configures VLANs as the criteria the router uses to match
packets to the traffic class.
vlanid is a VLAN identification number(s) or a range of
numbers. Valid values are from 1 to 4095.
