The remaining traffic classes, best-effort and video, remain in the default
traffic-class group.
Configuring the
Parameter Definitions
After configuring the traffic classes and traffic-class groups, the QoS administrator
configures the parameter definitions for Subscribers 1, 2, and 3.
1.
Configure a parameter definition for the maximum subscriber bandwidth.
a. Configure the parameter definition named max-subscriber-bandwidth.
b. Enable the parameter to control VLANs.
c. Enable the parameter to have instances created on VLAN subinterfaces.
d. Specify the valid range of this parameter as 512 Kbps–8 Mbps.
host1(config)# qos-parameter-define max-subscriber-bandwidth
host1(config-qos-parameter-define)# controlled-interface-type vlan
host1(config-qos-parameter-define)# instance-interface-type vlan
host1(config-qos-parameter-define)# range 512000 8192000
host1(config-qos-parameter-define)# exit
2.
Configure a parameter definition for a subscriber's weight in the hierarchical
round-robin (HRR) scheduler. This parameter is used to provide different scheduler
weights for each of the three service offerings.
a. Configure the parameter definition named subscriber-weight.
b. Enable the parameter to control VLANs.
c. Enable the parameter to have instances created on VLAN subinterfaces.
d. Specify the valid range of this parameter as 1–6.
host1(config)# qos-parameter-define subscriber-weight
host1(config-qos-parameter-define)# controlled-interface-type vlan
host1(config-qos-parameter-define)# instance-interface-type vlan
host1(config-qos-parameter-define)# range 1 6
host1(config-qos-parameter-define)# exit
3.
Configure a parameter definition for the subscriber's maximum video bandwidth.
By creating a parameter instance on S-VLANs, the QoS administrator can specify
a subscriber's maximum video bandwidth for each DSLAM in the hierarchy.
a. Configure the parameter definition named max-subscriber-video-bandwidth.
b. Enable the parameter to control VLANs.
c. Enable the parameter to have instances created on both SVLAN and VLAN
subinterfaces.
d. Specify the valid range of this parameter as 1 Mbps–5 Mbps.
host1(config)# qos-parameter-define max-subscriber-video-bandwidth
host1(config-qos-parameter-define)# controlled-interface-type vlan
host1(config-qos-parameter-define)# instance-interface-type vlan
host1(config-qos-parameter-define)# instance-interface-type svlan
host1(config-qos-parameter-define)# range 1000000 5000000
