Aggregate policers perform second stage policing (the first stage is controlled by individual policers) allowing policing of multiple flows/categories in aggregate. This allows first stage policers to become oversubscribed while still limiting aggregate incoming traffic from a given traffic category. The aggregate fill rate for an Aggregate policer is equal to the maximum value of the fill rates of referencing policers.

The following table defines the bucket sizes and fill rates for aggregate policers.
