Chapter 36 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.

These sections contain this configuration information:
• Configuring the CoS-to-DSCP Map, page 36-51 (optional)
• Configuring the IP-Precedence-to-DSCP Map, page 36-52 (optional)
• Configuring the Policed-DSCP Map, page 36-53 (optional, unless the null settings in the map are
not appropriate)
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.
