The QoS administrator configures the parameter definition for the maximum subscriber
bandwidth.
To configure a parameter definition for the maximum subscriber bandwidth:
Configure the parameter definition named max-sub-bw.
1.
Enable the parameter to control S-VLANs.
2.
Enable the parameter to control VLANs.
3.
Enable the parameter to have instances created on VLAN subinterfaces.
4.
Specify that the QoS client can create the parameter instance for VLANs, which
5.
represent subscribers.
host1(config)#qos-parameter-define max-sub-bw hierarchical
host1(config-qos-parameter-define)#controlled-interface-type svlan
host1(config-qos-parameter-define)#controlled-interface-type vlan
host1(config-qos-parameter-define)#instance-interface-type vlan
host1(config-qos-parameter-define)#subscriber-interface-type vlan
host1(config-qos-parameter-define)#exit
The QoS administrator can then reference the parameter definition within a scheduler
profile, which defines the shaping rates for the parameter.
Configure a scheduler profile to shape the throughput the explicit QoS parameters
1.
for VLANs.
a. Configure the scheduler profile named sp-shape-cvlan.
b. Configure the shaping rate by referencing the parameter max-sub-bw.
host1(config)#scheduler-profile sp-shape-cvlan
host1(config-scheduler-profile)#shaping-rate max-sub-bw
host1(config-scheduler-profile)#exit
Configure a scheduler profile to shape the S-VLAN throughput.
2.
a. Configure the scheduler profile named sp-shape-svlan.
b. Configure the shaping rate by referencing the parameter max-sub-bw.
host1(config)#scheduler-profile sp-shape-svlan
host1(config-scheduler-profile)#shaping-rate max-sub-bw
host1(config-scheduler-profile)#exit
By referencing the scheduler profiles within QoS profiles, the QoS administrator creates
the scheduler hierarchy. In this portion of the example, the QoS administrator configures
QoS profiles for the VLAN and the S-VLAN.
Configure the QoS profile for the VLAN interfaces.
1.
a. Configure the QoS profile named qp-shape-cvlan.
b. Configure the VLAN queue and reference the best-effort traffic class.
c. Configure the VLAN node and reference the scheduler profile for shaping VLANs.
