Configuring a Parameter Definition for QoS Downstream Rate

To associate a parameter instance with the QoS downstream rate application:

1. Configure traffic classes.

   host1(config)#traffic-class voice

   host1(config-traffic-class)#exit

   host1(config)#traffic-class best-effort

   host1(config-traffic-class)#exit

2. Create a parameter definition for the QoS downstream rate application.
   1. Configure the QoS parameter name and the application.

      host1(config)#qos-parameter-define downstreamVLAN application qos-downstream-rate

   2. Configure controlled-interface types.

      host1(config-qos-parameter-define)#controlled-interface-type vlan

      host1(config-qos-parameter-define)#controlled-interface-type ip

   3. Configure subscriber-interface types.

      host1(config-qos-parameter-define)#subscriber-interface-type vlan

3. Do one of the following:
   • For VLANs, configure the shaping mode by creating a parameter definition with the QoS cell mode application. Ensure that you specify a subscriber-interface type.

     See Configuring a Parameter Definition to Shape Ethernet Traffic Using Cell Mode.

   • For ATM VCs, configure the shaping mode by issuing the qos-shaping-mode command.

     See Configuring the QoS Shaping Mode for ATM Interfaces.

4. Enable QoS adaptive mode for the system by issuing the qos-adaptive-mode command in L2C Configuration mode.

   host1(config)#l2c

   host1(config-l2c)#qos-adaptive-mode

5. Enable the QoS downstream rate application to use downstream rates obtained from the Actual-Data-Rate-Downstream [26-130] DSL Forum VSA.

   host1(config)#aaa qos downstream-rate

6. Configure the scheduler profile for the shaping rate.

   host1(config)#scheduler-profile vlan1

   host1(config-scheduler-profile)#shared-shaping-rate downstreamVLAN * 5 auto

7. Configure the QoS profile for the shaping rate.

   host1(config)#qos-profile vlan1

   host1(config-qos-profile)#vlan node scheduler-profile vlan1

8. Attach the QoS profile to a logical Ethernet interface.

   ANCP or AAA dynamically creates the parameter instances for the QoS downstream rate application, and if applicable, the QoS cell mode application; therefore, you do not need to specify them.

   host1(config)#interface gigabitEthernet 6/0/2

   host1(config-if)#encapsulation vlan

   host1(config-if)#interface gigabitEthernet 6/0/2.1

   host1(config-if)#vlan id 1

   host1(config-if)#qos-profile vlan1

   host1(config-if)#ip address 6.10.10.10 255.255.255.255
