Purpose
Creates or modifies the parent policy.
policy-map-name is the name of the parent policy map. The name
can be a maximum of 40 alphanumeric characters.
Configures or modifies the parent class-default class.
You can configure only the class-default class in a parent
Note
policy. Do not configure any other traffic class.
(Optional) Specifies a bandwidth-remaining ratio for class-level
or subinterface-level queues to be used during congestion to
determine the amount of excess bandwidth (unused by priority
traffic) to allocate to non-priority queues.
ratio specifies the relative weight of this subinterface or queue
with respect to other subinterfaces or queues. Valid values are
from 1 to 1000.
Shapes traffic to the indicated bit rate and enables ATM overhead
accounting.
(Optional) average is the committed burst (Bc) that specifies the
maximum number of bits sent out in each interval. This option is
only supported on the PRE3.
mean-rate is also called committed information rate (CIR).
Indicates the bit rate used to shape the traffic, in bits per second.
When this command is used with backward explicit congestion
notification (BECN) approximation, the bit rate is the upper
bound of the range of bit rates that are permitted.
(Optional) burst-size is the number of bits in a measurement
interval (Bc).
(Optional) excess-burst-size is the acceptable number of bits
permitted to go over the Be.
account enables ATM overhead accounting.
qinq specifies queue-in-queue encapsulation as the
BRAS-DSLAM encapsulation type.
dot1q specifies IEEE 802.1Q VLAN encapsulation as the
BRAS-DSLAM encapsulation type.
aal5 is the ATM Adaptation Layer 5 that supports
connection-oriented variable bit rate (VBR) services.
subscriber-encaps specifies the encapsulation type at the
subscriber line. For more information, see the
Encapsulation Types" section on page
Applies the child policy to the parent class-default class.
policy-map-name is the name of the child policy map configured
in step 1.
