By referencing the scheduler profiles within QoS profiles, the QoS administrator
Configuring the QoS
creates the scheduler hierarchy. In this portion of the example, the QoS administrator
Profiles
configures QoS profiles for the best-effort data and triple-play service offerings.

Example: QoS Parameter Configuration for Controlling Subscriber Bandwidth
Configure a scheduler profile for the subscriber's voice service.
a. Configure the scheduler profile named subscriber-voice.
b. Configure the shaping rate by referencing the max-100Kbps-voice-calls
parameter and multiplying it by 100 Kbps of voice calls.
host1(config)#scheduler-profile subscriber-voice
host1(config-scheduler-profile)#shaping-rate max-100Kbps-voice-calls *
100000
host1(config-scheduler-profile)#exit
Define a QoS profile for the best-effort data service.
a. Create the QoS profile named subscriber-data-service.
b. Create a node for S-VLAN subinterfaces.
c. Specify a node for VLAN subinterfaces and reference the subscriber-weight
scheduler profile.
d. Specify a queue for VLAN subinterfaces, referencing the best-effort traffic
class and the subscriber-best-effort scheduler-profile.
host1(config)#qos-profile subscriber-data-service
host1(config-qos-profile)#svlan node
host1(config-qos-profile)#vlan node scheduler-profile subscriber-weight
host1(config-qos-profile)#vlan queue traffic-class best-effort scheduler-profile
subscriber-best-effort
host1(config-qos-profile)#exit
The best-effort queue rule for VLAN subinterfaces refers to the
subscriber-best-effort scheduler profile. The scheduler profile refers to the
max-subscriber-bandwidth parameter that controls the maximum rate of
this subscriber's best-effort queue.
Define a QoS profile for the triple-play service and specify S-VLAN nodes and
VLAN nodes.
a. Create a QoS profile named subscriber-triple-play.
b. Specify a node for S-VLAN subinterfaces.
c. Specify a node for VLAN subinterfaces and reference the subscriber-weight
scheduler profile.
d. Specify a node for S-VLAN subinterfaces and reference the EF traffic-class
group.
e. Specify a queue for VLAN subinterfaces, referencing the best-effort traffic
class and the subscriber-best-effort scheduler profile.
