Step 4
Router(config-pmap-c)# police [cir] percent
percent bc normal-burst-in-msec
be
excess-burst-in-msec [conform-action action
[exceed-action action [violate-action action]]]
(Optional) Configures traffic policing on the basis of a
percentage of bandwidth available on an interface.
(Optional) cir is the committed information rate (CIR) and
indicates an average rate at which the policer meters traffic.
CIR is based on the interface shape rate.
percent percent indicates to use the percentage of available
bandwidth specified in percent to calculate the CIR. Valid
values are from 1 to 100.
bc normal-burst-in-msec specifies the normal or committed
burst
size (CBS) that the first token bucket uses for policing
traffic. Specify the normal-burst-in-msec 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).
be excess-burst-in-msec specifies the excess burst size
(EBS) that the second token bucket uses for policing traffic.
Specify the excess-burst-in-msec value in milliseconds
(ms). Valid values are from 1 to 2000. The default value is
zero (0). You must specify normal-burst-in msec before you
specify excess-burst-in-msec.
Note Burst in milliseconds is based on the policing
committed information rate (CIR).
conform-action action is 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.
exceed-action action is the action to take on packets that
exceed the rate limit. The default action is drop. You must
specify the conform-action before you specify the
exceed-action.
violate-action action is an optional action that specifies the
action to take on packets that continuously exceed the rate
limit. The default action is the same as the exceed-action.
You must specify the exceed-action before you specify the
violate-action.
See Table 6-1 on page 6-3 for a description of each action
you can specify.
Note Repeat Step 2 through Step 4 to configure additional
traffic classes. For information about additional
actions you can specify, see the
“Types of QoS
Actions” section on page 3-4.
Step 5
Router(config-pmap-c)# exit
Exits policy-map class configuration mode.
