Configuring Default Class Maps
Each time you create a new policy map, a new class map called default is
created automatically and assigned to the policy map. A default class map
enables you to specify the action that applies to all unclassified traffic
within a policy map. This unclassified traffic is comprised of all traffic within
a policy-map that is independent of the class maps within a policy map.
Using default class maps simplifies QoS configuration. First, specify what
you want to filter in the class maps. Then, configure the default class map
with one of the following settings:
 Permit unspecified traffic. This is the default setting.
 Deny unspecified traffic.
 Copy unspecified traffic to the mirrored port.
You configure the default action of the default class map with the
DEFAULT-ACTION command. For more information about this command,
see “DEFAULT-ACTION” on page 1602.
The following example sets the action of the default class map to deny
packets of unclassified data within a policy map.
