Shaping PPPoE Over VLAN Sessions Using RADIUS
Purpose
Shapes traffic to the indicated bit rate and enables ATM overhead
accounting.
rate is the bit-rate used to shape the traffic, expressed in kilobits
per second.
account enables ATM overhead accounting. For more
information, see Chapter 10, "Overhead Accounting."
qinq specifies queue-in-queue encapsulation as the broadband
aggregation system-DSLAM encapsulation type.
dot1q specifies IEEE 802.1Q VLAN encapsulation as the
broadband aggregation system-DSLAM encapsulation type.
aal5 specifies the ATM Adaptation Layer 5 that supports
connection-oriented variable bit rate (VBR) services. You must
specify either aal5 or aal3.
aal3 specifies the ATM Adaptation Layer 5 that supports both
connectionless and connection-oriented links. You must specify
either aal3 or aal5.
subscriber-encapsulation specifies the encapsulation type at the
subscriber line.
user-defined indicates that the router is to use the offset you
specify when calculating ATM overhead.
offset specifies the offset size the router is to use when calculating
ATM overhead. Valid values are from -63 to 63 bytes.
The router configures the offset size if you do not specify
Note
the user-defined offset option.
atm applies ATM cell tax in the ATM overhead calculation.
Configuring both the offset and atm options adjusts the
Note
packet size to the offset size and then adds ATM cell tax.
Applies a bottom-level child policy to the top-level parent
class-default class.
policy-map-name is the name of the previously configured child
policy map.
