Table29-13 Configure Policing
Element Description
Specify the access rate parameters for policing
Committed Information Rate
(CIR)
Enter the CIR to be used for the policy in kilobits per second. When
the traffic rate reaches the CIR, excess traffic is dropped or
remarked.
Normal Burst Size (BC) Optional. Enter the normal burst size in kilobits per second. The
normal burst size determines how large traffic bursts can be before
some traffic exceeds the CIR.
Excess Burst Size (BE) Optional. Enter the excess burst size in kilobits per second. The
excess burst size determines how large traffic bursts can be before
all traffic exceeds the rate limit. Traffic that falls between the
normal burst size and the excess burst size exceeds the rate limit
with a probability that increases as the burst size increases.
Action Type This column lists the names of the actions that you can choose for
traffic that conforms to, exceeds, or violates the configured CIR,
BC, and BE parameters.
Action Choose what you want the router to do when traffic conditions
conform, exceed or violate configured policing parameters. The
conform and the exceed actions are mandatory and have default
values. The violate action is optional. The available actions are the
following:
•Drop—(Default for exceed action) Discard the pa cket.
•None—(Available for violate action)
•Set DSCP Transmit—Set the DSCP and transmit.
•Transmit—(Default for conform action) Send the packet.
Optional parameters Optional parameters are enabled when you choose the Set DSCP
Transmit action. The options displayed are the available DSCP
markings.
