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.
