Applications And Qos Parameters; Scheduler Profiles And Parameter Expressions For Qos Administrators; Referencing A Parameter Definition In A Scheduler Profile - Juniper JUNOSE 11.1.X - QUALITY OF SERVICE CONFIGURATION GUIDE 3-21-2010 Configuration Manual

Applications and QoS Parameters

You can associate a parameter definition with an application in the system by issuing
the application keyword with the qos-parameter-define command. The applications
that you can configure include:

Scheduler Profiles and Parameter Expressions for QoS Administrators

After you have created the parameter definition, you reference the parameter within
a scheduler profile. You can choose to use parameter expressions in the scheduler
profile.

Referencing a Parameter Definition in a Scheduler Profile

You can reference a parameter in a scheduler profile as long as all parameters in the
scheduler profile share at least one controlled-interface type. Otherwise, a QoS profile
rule cannot reference the scheduler profile.
For example:
When a scheduler profile references a parameter, the system implicitly assigns
controlled-interface types to the scheduler profile that are the same as the
controlled-interface types of all referenced parameters. The system validates scheduler
profile types using the QoS profile rules that refer to those scheduler profiles. For
example, if the parameter definition max-sub-bw has the controlled-interface types
atm-vc and ip, the scheduler profile cannot be referenced in QoS profile rules that
have a type other than atm-vc or ip.
