Chapter 1 Configuring QoS
Configuring Standard QoS
To remove the specified aggregate policer from a policy map, use the no police aggregate
aggregate-policer-name policy map configuration mode. To delete an aggregate policer and its
parameters, use the no mls qos aggregate-policer aggregate-policer-name global configuration
command.
This example shows how to create an aggregate policer and attach it to multiple classes within a policy
map. In the configuration, the IP ACLs permit traffic from network 10.1.0.0 and from host 11.3.1.1. For
traffic coming from network 10.1.0.0, the DSCP in the incoming packets is trusted. For traffic coming
from host 11.3.1.1, the DSCP in the packet is changed to 56. The traffic rate from the 10.1.0.0 network
and from host 11.3.1.1 is policed. If the traffic exceeds an average rate of 48000 b/s and a normal burst
size of 8000 bytes, its DSCP is marked down (based on the policed-DSCP map) and sent. The policy
map is attached to an ingress port.
Switch(config)# access-list 1 permit 10.1.0.0 0.0.255.255
Switch(config)# access-list 2 permit 11.3.1.1
Switch(config)# mls qos aggregate-police transmit1 48000 8000 exceed-action
policed-dscp-transmit
Switch(config)# class-map ipclass1
Switch(config-cmap)# match access-group 1
Switch(config-cmap)# exit
Switch(config)# class-map ipclass2
Switch(config-cmap)# match access-group 2
Switch(config-cmap)# exit
Switch(config)# policy-map aggflow1
Switch(config-pmap)# class ipclass1
Step 4
policy-map policy-map-name Create a policy map by entering the policy map name, and enter
policy-map configuration mode.
For more information, see the “Classifying, Policing, and Marking
Traffic on Physical Ports by Using Policy Maps” section on
page 1-58
.
Step 5 class [ class-map-name | class-default ] Define a traffic classification, and enter policy-map class
configuration mode.
For more information, see the “Classifying, Policing, and Marking
Traffic on Physical Ports by Using Policy Maps” section on
page 1-58
.
Step 6 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.
Step 7
exit Return to global configuration mode.
Step 8 interface interface-id Specify the port to attach to the policy map, and enter interface
configuration mode.
Valid interfaces include physical ports.
Step 9
service-policy input policy-map-name Specify the policy-map name, and apply it to an ingress port.
Only one policy map per ingress port is supported.
Step 10
end Return to privileged EXEC mode.
Step 11
show mls qos aggregate-policer
[ aggregate-policer-name ]
