Table 23: Attributes in Parameter Definitions (continued)
Description Parameter Data Setting
Subscriber interfaces to which QoS clients can apply
parameters obtained through RADIUS or profiles. The QoS
administrator can specify up to four subscriber-interface
types for each parameter definition. Subscriber-interface type
Valid range of values that a QoS client can specify. Range
Boolean that indicates whether the parameter uses implicit
parameter instances, which are the sum of explicit instances
of the parameter on all scheduler nodes or queues above
them in the scheduler hierarchy. Expression
Application that binds parameter instance to a specific
application, such as IP multicast bandwidth adjustment. Application
Naming Guidelines for QoS Parameters
You define the parameter name by issuing the qos-parameter-define command to
enter QoS Parameter Definition Configuration mode.
The naming guidelines for parameters differ from other QoS features such as QoS
profiles and scheduler profiles.
Parameter names must begin with a letter to avoid confusion with numbers and
operators. Because QoS clients reference this parameter name to create a parameter
instance, we recommend that you use a name that is descriptive.
Table 24 on page 230 lists some sample parameter names and descriptions.
Table 24: Sample Parameter Names
Description Parameter Name
Total bandwidth for a subscriber (average of
all services) max-subscriber-bandwidth
Shaping rate for a subscriber voice queue max-voice-bandwidth
Assured rate for a priority-data service queue min-data-bw
Shaping rate for the same priority data
service queue as min-data-sw max-data-bw
In addition, parameter names cannot be the same as an arithmetic operator. Table
25 on page 231 lists examples of valid and invalid parameter names that use operators.
