Guidelines for Configuring QoS Downstream Rate
When you specify the QoS downstream rate application, the following considerations
apply:
■
You can have only one parameter definition with the QoS downstream rate
configured.
■
You must specify a controlled-interface type.
■
You must configure a subscriber-interface-type. ANCP uses the
subscriber-interface type to determine the instance-interface type on which to
dynamically create the parameter.
■
Access loops can synchronize after the user has logged in. The business logic
depends on the rate that is reported in the Access-Request message. We
recommend that service providers use RADIUS Connect-Info attribute [77] as
the default value for their business logic. When the ANCP rate information is not
present, the system uses the default QoS parameter instance (which can be
defined globally or per VLAN). The advisory transmit speed configurable per
VLAN is reported to the RADIUS Connect-Info attribute [77]. Ensure that the
value of the default QoS parameter is aligned with the value in RADIUS
Connect-Info attribute 77.

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.
a. Configure the QoS parameter name and the application.
