Configuring Enhanced Hierarchical Ingress Policing - Cisco ASR 9000 Series Configuration Manual

Configuring Enhanced Hierarchical Ingress Policing

Configuring Enhanced Hierarchical Ingress Policing
The difference between configuring enhanced hierarchical ingress policing and configuring hierarchical ingress
policing is the addition of the child-conform-aware command.
When used in the parent policer, the child-conform-aware command prevents the parent policer from dropping
any ingress traffic that conforms to the maximum rate specified in the child policer.
Restrictions
Enhanced Hierarchical Ingress Policing has the following limitations:
• Ingress direction only.
• Sum of all child policer rates cannot be greater than the parent policer rate.
• Single-rate two-color policer (color blind) only.
• Configurations that specify burst size in the police rate command are supported; configurations that
• Configure the child-conform-aware command only in the parent policer.
SUMMARY STEPS
1. configure
2. policy-map policy-name
3. class class-name
4. service-policy policy-map-name
5. police rate {value [units] | percent percentage} [burst burst-size [burst-units]] [peak-rate value [units]]
[peak-burst peak-burst [burst-units]]
6. child-conform-aware
7. conform-action [drop | set options | transmit]
8. exceed-action [drop | set options | transmit]
9. end or commit
