class
Policy-map Configuration mode command defines a traffic
classification and enters the Policy-map Class Configuration mode. Use the

acl-name
]
no class
class-map-name
Parameters
•
class-map-name
—Specifies the name of an existing class map. If the class
map does not exist, a new class map is created under the specified name.
•
acl-name
—Specifies the name of an IP or MAC Access Control List
(ACL).
Default Configuration
No class map is defined for the policy map.
Command Mode
Policy-map Configuration mode
User Guidelines
Use the
policy-map
Global Configuration mode command to identify the
policy map and to enter the Policy-map Configuration mode before using the
class
command. After specifying a policy map, a policy for new classes can be
configured or a policy for any existing classes in that policy map can be
modified.
Use the
service-policy
Interface Configuration (Ethernet, Port-channel)
mode command to attach a policy map to an interface. Use an existing class
map to attach classification criteria to the specified policy map and use the
access-group
parameter to modify the classification criteria of the class map.
If this command is used to create a new class map, the name of an IP or MAC
ACL must also be specified with the
access-group
parameter.
