示例：将计划和整形应用于 VLAN
此示例说明如何将时间表应用到单个逻辑接口。
要求
此示例使用以下硬件和软件组件：
在支持智能排队 （IQ） 的路由器线卡上运行的 Junos OS 版本 7.4 或更高版本。
在包含 16 个 10GE MPC 或 MPC3E 线卡的 MX 系列路由器上运行的 Junos OS 版本 13.2 或更高版本。
在包含 MPC4E 线卡的 MX 系列路由器上运行的 Junos OS 版本 13.3 或更高版本。
在包含 MPC6E 线卡的 MX 系列路由器上运行的 Junos OS 版本 15.1 或更高版本。
概述
默认情况下，逻辑接口上未启用输出调度。未配置整形的逻辑接口共享默认时间表。 逻辑接口调度 （又称为 单位调度）允许您在逻辑接口上启用多个输出队列，并为每个队列关联自定义调度和整形。
要启用单位计划，请在层次结构级别中[edit interfaces interface name]包含per-unit-scheduler语句。启用按单元时间表时，可通过在层次结构级别中包括scheduler-map语句来定义逻辑接口的[edit class-of-service interfaces interface name unit logical unit number]专用时间表。或者，您也可以在层次结构级别中[edit class-of-service traffic-control-profiles traffic control profile name]包含scheduler-map语句，然后在层次结构级别中[edit class-of-service interfaces interface name unit logical unit number]包含output-traffic-control-profile语句。
此示例说明如何通过使用流量控制配置文件为逻辑接口定义时间表。
配置
CLI 快速配置
要快速配置此示例，请复制以下命令，将其粘贴到文本文件中，移除任何换行符，更改与网络配置匹配所需的任何详细信息，然后将命令复制粘贴到层次结构级别的 [edit] CLI 中。
