Hierarchical policers
Note Hierarchical policers are only supported on Supervisor Engine V-10GE.
You can tie flow policers with the existing policers to create dual policing rates on an interface. For
example, using dual policing, you can limit all incoming traffic rates on a given interface to 50 Mbps
and can limit the rate of each flow that is part of this traffic to 2 Mbps.
