Classifying, Policing, and Marking Traffic by Using Aggregate Policers
By using an aggregate policer, you can create a policer that is shared by multiple traffic classes within
the same policy map. However, you cannot use the aggregate policer across different policy maps or
ports.
You can configure aggregate policers only in nonhierarchical policy maps on physical ports.
Beginning in privileged EXEC mode, follow these steps to create an aggregate policer:
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2 mls qos aggregate-policer
aggregate-policer-name rate-bps burst-byte
exceed-action {drop |
policed-dscp-transmit} 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
“Standard QoS Configuration
Guidelines” section on page 36-32 .
• 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
“Configuring the
Policed-DSCP Map” section on page 36-62 .
Step 3 class-map [match-all | match-any]
class-map-name Create a class map to classify traffic as necessary. For more
information, see the
“Classifying Traffic by Using Class Maps”
section on page 36-46 and the “Creating Named Standard and
Extended ACLs” section on page 34-15 .
