Hierarchical Policer as Filter Action
Hierarchical policer as filter action enables you to have hierarchial policers as one type of filter action. This is useful in provider edge applications using aggregate policing for general traffic and to apply a separate policer for premium traffic on a logical or physical interface. An interface-specific filter can have a hierarchical policer as a filter action whether or not the hierachical policer is a logical interface policer. A non-interface-specific filter can only have a hierarchical policer without using logical interface-specific as a filter action. The following table summarizes where you can use an interface-specific filter.
Interface-specific Filter | Hierarchical Policer Logical-interface-policer | Allowed |
|---|---|---|
no | no | yes |
no | yes | no |
yes | no | yes |
yes | no | yes |
To enable all hierarchical policers of the same name in one filter to share the same policer instance in PFE, use the filter-specific statement at the [edit firewall] hierarchy level.
