Class of Service

Hierarchical policer functionality extended to Modular Interface Cards (MICs) (MX
Series routers)—Provides hierarchical policer feature parity with Enhanced Intelligent
Queuing (IQE) PICs. This is useful in provider edge applications using aggregate policing
for general traffic and when applying a separate policer for premium traffic on a logical
or physical interface.
Hierarchical policing on MICs supports the following features:
Ingress traffic is first classified into premium and non-premium traffic before a policer
is applied.
The hierarchical policer contains two policers: premium and aggregate.
Premium traffic is policed by both the premium policer and the aggregate policer. While
the premium policer rate-limits premium traffic, the aggregate policer only decrements
the credits but does not drop packets. Non-premium traffic is rate-limited by the
aggregate policer only, resulting in the following behavior:
Premium traffic is assured to have the bandwidth configured for the premium policer.
Non-premium traffic is policed to the specified rate limit.
For a list of supported MICs, refer to:

hierarchical policer parameters beyond those of the IQE PICs.
You can apply the policer at the inet, inet6, or mpls family level, as follows:
