Shaping and Queuing Per-Session Traffic on LNS
Step 3
Router(config-pmap-c)# bandwidth
{bandwidth-kbps | percent percentage |
remaining percent percentage} account
{{{qinq | dot1q} {aal5 | aal3}
{subscriber-encap}} | {user-defined
offset [atm]}}
Enables class-based fair queuing.
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.
percent percentage specifies or modifies the minimum
percentage of the link bandwidth allocated for a class belonging
to a policy map. Valid values are from 1 to 99.
remaining percent 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. For more
information, see the
“ATM Overhead Accounting” section on
page 10-2.
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-encap specifies the encapsulation type at the
subscriber line. For more information, see the
“Overhead
Accounting and Hierarchical Policies” section on page 10-6.
Step 3
(cont.)
Router(config-pmap-c)# bandwidth
{bandwidth-kbps | percent percentage |
remaining percent percentage} account
{{{qinq | dot1q} {aal5 | aal3}
{subscriber-encap}} | {user-defined
offset [atm]}}
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.
Note The router configures the offset size if you do not specify
the offset option.
atm applies 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 ATM cell tax.
Step 4
Router(config-pmap-c)# exit
Exits policy-map class configuration mode.
Step 5
Router(config-pmap)# policy-map
policy-map-name
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.
Step 6
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.
