5. Use the set command to modify the QoS value for matching traffic class, and
use the policer command to monitor the average flow and burst rate, and drop
any traffic that exceeds the specified rate, or just reduce the DSCP service level
for traffic exceeding the specified rate.
6. Use the service-policy command to assign a policy map to a specific interface.
Notes: 1.
You can configure up to 16 rules per Class Map. You can also include
multiple classes in a Policy Map.
2.
You should create a Class Map (page 4-258) before creating a Policy Map
(page 4-261). Otherwise, you will not be able to specify a Class Map with the
class command (page 4-261) after entering Policy-Map Configuration mode.
class-map
This command creates a class map used for matching packets to the specified
class, and enters Class Map configuration mode. Use the
no form to delete a class
map and return to Global configuration mode.
Syntax
[ no ] class-map class-map-name [ match-any ]
• match-any - Match any condition within a class map.
• class-map-name - Name of the class map. (Range: 1-16 characters)
Default Setting
None
Command Mode
Global Configuration
Command Usage
• First enter this command to designate a class map and enter the Class Map
configuration mode. Then use the match command (page 4-259) to specify
the criteria for ingress traffic that will be classified under this class map.
• Up to 16 match commands are permitted per class map.
• The class map is used with a policy map (page 4-261) to create a service
policy (page 4-264) for a specific interface that defines packet classification,
service tagging, and bandwidth policing.
Example
This example creates a class map call “rd_class,” and sets it to match packets
marked for DSCP service value 3:
