Purpose
Assigns the traffic class you specify to the policy map.
Enters policy-map class configuration mode.
class-map-name is the name of a previously configured
class map.
Enables class-based fair queuing and overhead accounting.
bandwidth-kbps specifies or modifies the minimum
bandwidth allocated for a class belonging to a policy map.
Valid values are from 8 to 2,488,320, which represents from
1 to 99 percent of the link bandwidth.
percentage specifies or modifies the maximum percentage
of the link bandwidth allocated for a class belonging to a
policy map. Valid values are from 1 to 99.
remaining percentage specifies or modifies the minimum
percentage of unused link bandwidth allocated for a class
belonging to a policy map. Valid values are from 1 to 99.
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 specifies the ATM Adaptation Layer 5 that supports
connection-oriented variable bit rate (VBR) services.
subscriber-encap specifies the encapsulation type at the
subscriber line. For more information, see the
Accounting and Hierarchical Policies" section on
page 10-6.
user-defined indicates that the router is to use the offset
value you specify when calculating ATM overhead.
offset specifies the number of bytes the router is to use when
calculating overhead. Valid values are from -63 to 63 bytes.
atm applies the ATM cell tax in the ATM overhead
calculation.
Note Configuring both the offset and atm options adjusts
the packet size to the offset size and then adds the
ATM cell tax.
Exits policy-map class configuration mode.
Creates or modifies the top-level 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.
