Configuring QoS
Configuring QoS
Beginning in privileged EXEC mode, follow these steps to create a 2-rate, 3-color aggregate policer:
Command Purpose
1. configure terminal Enter global configuration mode.
2. policer aggregate aggregate-policer-name
{ rate-bps | cir cir-bps } [ bc burst- value ]
[ conform-action [ set-cos-transmit
{ cos_value | [ cos | dscp | precedence ] [ table

{ dscp_value | [ cos | dscp | precedence ]
[ table table-map name ]} | set-prec-transmit
{ precedence_value | [ cos | dscp |
precedence ] [ table table-map name ]} |
set-qos-transmit qos-group_value |

set-cos-transmit { cos_value | [ cos | dscp |

set-dscp-transmit { dscp_value | [ cos | dscp
| precedence ] [ table table-map name ]} |
set-prec-transmit { precedence_value | [ cos
| dscp | precedence ] [ table table-map
name ]} | set-qos-transmit qos-group_value
| transmit ]]
Define the policer parameters that can be applied to multiple traffic
classes within the same policy map.

For aggregate-policer-name , specify the name of the
aggregate policer.

For rate-bps, specify average traffic rate in bits per second
(bps). The range is 8000 to 1000000000.

For cir cir-bps, specify the committed information rate in bits
per second. The range is 8000 to 1000000000 bps.

( Optional) For bc burst-value , specify conform burst and the
number of acceptable burst bytes. The range is 8000 to
1000000 bytes.

(Optional) For conform-action , specify the action to take on
packets that conform to the CIR. The default is to send the
packet.

(Optional) For exceed-action , specify the action to take on
packets that exceed the CIR. The default is to drop the packet.
See the command reference for this release or Configuring Input
Policy Maps with Individual Policing, page 611 for definitions of the
available keywords.
3. policy-map policy-map-name Create a policy map by entering the policy map name, and enter
policy-map configuration mode.
4. class { class-map-name | class-default } Enter a class-map name or class-default to match all unclassified
packets, and enter policy-map class configuration mode.
If you enter a class-map name, you must have already created the
class map by using the
class-map global configuration command.
5. police aggregate aggregate-policer-name Apply an aggregate policer to multiple classes in the same policy
map. For
aggregate-policer-name , enter the name specified in
Step 2.
6. exit Return to policy-map configuration mode.
7. exit Return to global configuration mode.
8. interface interface-id Enter interface configuration mode for the interface to which you
want to attach the policy.
9. service-policy input policy-map-name Attach the policy map (created in Step 3) to the ingress interface.
10. end Return to privileged EXEC mode.
11. end Return to privileged EXEC mode.
12. show policer aggregate
[ aggregate-policer-name ]
Verify your entries.
13. copy running-config startup-config (Optional) Save your entries in the configuration file.
