Ejemplo: aplicación de programación y configuración a VLAN
En este ejemplo se muestra cómo aplicar programadores a interfaces lógicas individuales.
Requisitos
En este ejemplo se utilizan los siguientes componentes de hardware y software:
Junos OS versión 7.4 o posterior ejecutándose en tarjetas de línea de enrutador compatibles con Intelligent Queuing (IQ).
Junos OS versión 13.2 o posterior que se ejecuta en enrutadores serie MX que contienen tarjetas de línea MPC o MPC3E 16x10GE.
Junos OS versión 13.3 o posterior ejecutándose en enrutadores serie MX que contengan tarjetas de línea MPC4E.
Junos OS versión 15.1 o posterior ejecutándose en enrutadores serie MX que contengan tarjetas de línea MPC6E.
Visión general
De forma predeterminada, la programación de resultados no está habilitada en las interfaces lógicas. Las interfaces lógicas sin configuración configuradas comparten un programador predeterminado. La programación de interfaz lógica (también denominada programación por unidad) permite habilitar varias colas de salida en una interfaz lógica y asociar programación y formas personalizadas para cada cola.
Para habilitar la programación por unidad, incluya la per-unit-scheduler instrucción en el nivel jerárquico[edit interfaces interface name]. Cuando los programadores por unidad están habilitados, puede definir programadores dedicados para interfaces lógicas incluyendo la scheduler-map instrucción en el nivel de [edit class-of-service interfaces interface name unit logical unit number] jerarquía. Como alternativa, puede incluir la instrucción en el nivel de jerarquía y, a continuación, incluir la scheduler-map output-traffic-control-profile instrucción en el nivel de [edit class-of-service traffic-control-profiles traffic control profile name] [edit class-of-service interfaces interface name unit logical unit number] jerarquía.
En este ejemplo se muestra cómo definir programadores para interfaces lógicas mediante el uso de perfiles de control de tráfico.
Configuración
Configuración rápida de CLI
Para configurar rápidamente este ejemplo, copie los siguientes comandos, péguelos en un archivo de texto, elimine los saltos de línea, cambie los detalles necesarios para que coincidan con su configuración de red y, a continuación, copie y pegue los comandos en la CLI en el nivel de [edit] jerarquía.
