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 216 lists some sample parameter names and descriptions.
Table 24: Sample Parameter Names
Parameter Name
max-subscriber-bandwidth
max-voice-bandwidth
min-data-bw
max-data-bw
In addition, parameter names cannot be the same as an arithmetic operator. Table 25
on page 217 lists examples of valid and invalid parameter names that use operators.
Description
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.
Valid range of values that a QoS client can specify.
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.
Application that binds parameter instance to a specific
application, such as IP multicast bandwidth adjustment.
Description
Total bandwidth for a subscriber (average of
all services)
Shaping rate for a subscriber voice queue
Assured rate for a priority-data service queue
Shaping rate for the same priority data
service queue as min-data-sw
