(Optional) Committed information rate (CIR). Indicates an average rate at
which the policer meters traffic. CIR is based on the interface shape rate.
Indicates to use the percentage of available bandwidth specified in percent
to calculate the CIR. Valid values are from 1 to 100.
first token bucket uses for policing traffic. Specify the CBS value in
milliseconds (ms). Valid values are from 1 to 2000. The default value is
the greater of 2 ms worth of bytes at the police rate or the network
minimum transmission unit (MTU).
(Optional) Peak information rate (PIR), expressed as a percentage.
Indicates the rate at which the second token bucket is updated. Valid values
are from 1 to 100.
Note
(Optional) Specifies the excess burst size (EBS) that the second token
bucket uses for policing traffic. Specify the EBS value in milliseconds
(ms). Valid values are from 0 to 2000. The default value is zero (0). You
must specify normal-burst-in msec before you specify
excess-burst-in-msec.
Note
(Optional) Specifies the action to take on packets that conform to the rate
limit. The default action is transmit. You must specify a value for
excess-burst-in-msec before you specify the conform-action.
(Optional) Specifies the action to take on packets that exceed the rate limit,
but not the PIR. The default action is drop. You must specify the
conform-action before you specify the exceed-action.
(Optional) Specifies the action to take on packets that continuously exceed
the PIR rate limit. The default action is the same as the exceed-action. You
must specify the exceed-action before you specify the violate-action.

for a description of each action you can specify.
Description
The police percent command was introduced on the PRE1.
This command was introduced on the PRE2.
When using percent-based policing, you must explicitly enter the
PIR value.
Burst in milliseconds is based on the policing committed
information rate (CIR).
