Step 4
bandwidth {

}
or
bandwidth remaining [percent
percentage-value
| ratio
ratio-value
]
or
shape average {percent
percentage
|
rate
[
units
]}
Example:
RP/0/RSP0/CPU0:router(config-pmap-c)#
bandwidth percent 30
or
RP/0/RSP0/CPU0:router(config-pmap-c)#
bandwidth remaining percent 80
or
RP/0/RSP0/CPU0:router(config-pmap-c)# shape
average percent 50
Specifies the minimum bandwidth allocated to a
class as a percentage of link bandwidth.
Specifies how to allocate excess bandwidth to a
class.
Specifies maximum bandwidth as a percentage of
link bandwidth (when other classes are not using
all of their bandwidth share).
Note You must configure at least one of the
three parameters.
Step 5
exit
Example:
RP/0/RSP0/CPU0:router(config-pmap-c)# exit
Exits policy map class configuration mode.
Step 6
policy-map
policy-name
Example:
RP/0/RSP0/CPU0:router(config-pmap)#
policy-map Top-Parent
Creates or modifies the top-level policy.
Step 7
class class-default
Example:
RP/0/RSP0/CPU0:router(config-pmap)# class
class-default
Configures or modifies the parent class-default
class.
Note You can configure only the class-default
class in a parent policy. Do not configure
any other traffic class.
Step 8
shape average {percent
percentage
|
rate
[
units
]}
Example:
RP/0/RSP0/CPU0:router(config-pmap-c)# shape
average 1 mbps
(Optional) Shapes traffic to the indicated bit rate.
