(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.
percent
percent
indicates to use the percentage of available
bandwidth specified in
percent
to calculate the CIR.
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
burst-excess
before you specify the
conform-action
.
exceed-action
action
is 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)
violate-action
action
is 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
.
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.
Step 6
Router(config)#
policy-map
policy-map-name
Creates or modifies the parent policy map. Enters
policy-map configuration mode.
policy-map-name
is the name of the policy map. The name
can be a maximum of 40 alphanumeric characters.
