Policy Table
To create a single policer:
1 Create a policy in the Policy Table pages
2 Configure the policy in the Policy Class Maps pages. Here the policy class
can be designated as containing a single policer, or it can be designated as
containing Aggregate policers.
A policy can consist of one of the following:
• One or more class maps of ACLs that define the traffic flows in the policy.
• One or more aggregate policers that apply the QoS to the traffic flows in
the policy.
Only those policies that are bound to an interface are active (see the Policy
Binding pages).
After a policy has been added, class maps can be added in the Policy Table
pages.
