Defining Aggregate Policer
A policy is a collection of classes, each of which is a combination of a class map
and a QoS action to apply to matching traffic. Classes are applied in a first-fit
manner within a policy.
Before configuring policies for classes whose match criteria are defined in a class
map, a class map must first be defined, or the name of the policy map to be
created, added to, or modified must first be specified. Class policies can be
configured in a policy map only if the classes have defined match criteria.
An aggregate policer can be applied to multiple classes in the same policy map,
but an aggregate policer cannot be used across different policy maps. Define an
aggregate policer if the policer is shared with multiple classes. Policers in one port
cannot be shared with other policers in another device. Traffic from two different
ports can be aggregated for policing purposes.
To define Aggregate Policers:
STEP 1 Click Quality of Service > Advanced Mode > Aggregate Policer. The Aggregate
Policer Page
opens:
Aggregate Policer Page
The
Aggregate Policer Page contains the following fields.
• Aggregate Policer Name— Specifies the Aggregate Policer Name
