Configuring Standard QoS
Beginning in privileged EXEC mode, follow these steps to create an aggregate policer:

Step 1
configure terminal
Step 2
mls qos aggregate-policer
aggregate-policer-name rate-bps burst-byte
exceed-action {drop |
policed-dscp-transmit}
class-map [match-all | match-any]
Step 3
class-map-name
Step 4 policy-map policy-map-name
Step 5
class class-map-name
Step 6
police aggregate aggregate-policer-name
Step 7
exit
Step 8 interface interface-id
Step 9 service-policy input policy-map-name

Purpose
Enter global configuration mode.
Define the policer parameters that can be applied to multiple traffic
classes within the same policy map.
By default, no aggregate policer is defined. For information on the
number of policers supported, see the
Guidelines" section on page
For aggregate-policer-name, specify the name of the aggregate
•
policer.
For rate-bps, specify average traffic rate in bits per second
•
(b/s). The range is 8000 to 1000000000.
For burst-byte, specify the normal burst size in bytes. The range
•
is 8000 to 1000000.
Specify the action to take when the rates are exceeded. Use the
•
exceed-action drop keywords to drop the packet. Use the
exceed-action policed-dscp-transmit keywords to mark down
the DSCP value (by using the policed-DSCP map) and to send
the packet. For more information, see the
Policed-DSCP Map" section on page
Create a class map to classify traffic as necessary. For more
information, see the "Classifying Traffic by Using Class Maps"
section on page 39-51 and the
Extended ACLs" section on page
Create a policy map by entering the policy map name, and enter
policy-map configuration mode.
For more information, see the
Traffic on Physical Ports by Using Policy Maps" section on
page 39-56.
Define a traffic classification, and enter policy-map class
configuration mode.
For more information, see the
Traffic on Physical Ports by Using Policy Maps" section on
page 39-56.
Apply an aggregate policer to multiple classes in the same policy
map.
For aggregate-policer-name, enter the name specified in Step 2.
Return to global configuration mode.
Specify the port to attach to the policy map, and enter interface
configuration mode.
Valid interfaces include physical ports.
Specify the policy-map name, and apply it to an ingress port.
Only one policy map per ingress port is supported.
