Hierarchical Policing: Examples

ASR 9000 Ethernet Line Cards
This example shows a two-level policy with police actions at each level. There are two classes in the top
level, one for each customer. Aggregated traffic from each customer is subject to a rate limit as specified
by the police rate command in the top level. Traffic in different classes in the bottom level is limited by
an additional set of police actions to control different types of traffic for each customer.

SIP 700 for the ASR 9000
In this example, policers are specified in the policy child in class Prec1 and class Prec3, and also in the
class-default in the policy parent. The policers in the child policy, police traffic in class Prec1 at 30
percent (of 50 percent), police traffic in class Prec3 at 60 percent (of 50 percent) and police any other
traffic at 10 percent (of 50 percent). Cumulatively, all traffic on the interface is policed at 50 percent of
the interface rate by the policer in the parent policy.
