Beispiel: Anwendung von Scheduling und Shaping auf VLANs
Dieses Beispiel zeigt, wie Sie Scheduler auf einzelne logische Schnittstellen anwenden.
Anforderungen
In diesem Beispiel werden die folgenden Hardware- und Softwarekomponenten verwendet:
Junos OS Version 7.4 oder höher läuft auf Router-Linecards, die Intelligent Queuing (IQ) unterstützen.
Junos OS Version 13.2 oder höher, die auf Routern der MX-Serie ausgeführt wird, die 16x10GE MPC- oder MPC3E-Linecards enthalten.
Junos OS Version 13.3 oder höher, die auf Routern der MX-Serie ausgeführt wird, die MPC4E-Linecards enthalten.
Junos OS Version 15.1 oder höher, die auf Routern der MX-Serie ausgeführt wird, die MPC6E-Linecards enthalten.
Übersicht
Die Ausgabeplanung ist auf logischen Schnittstellen standardmäßig nicht aktiviert. Logische Schnittstellen ohne Konfiguration nutzen einen Standard-Scheduler. Mit der logischen Schnittstellenplanung (auch pro Einheitsplanung genannt) können Sie mehrere Ausgabewarteschlangen auf einer logischen Schnittstelle aktivieren und für jede Warteschlange benutzerdefinierte Planung und Shaping zuordnen.
Um die Planung pro Einheit zu ermöglichen, fügen Sie die per-unit-scheduler Anweisung auf Hierarchieebene [edit interfaces interface name] ein. Wenn Planer pro Einheit aktiviert sind, können Sie dedizierte Scheduler für logische Schnittstellen definieren, indem Sie die scheduler-map Anweisung auf Hierarchieebene [edit class-of-service interfaces interface name unit logical unit number] einbinden. Alternativ können Sie die scheduler-map Anweisung auf Hierarchieebene [edit class-of-service traffic-control-profiles traffic control profile name] einschließen und die output-traffic-control-profile Anweisung dann auf [edit class-of-service interfaces interface name unit logical unit number] Hierarchieebene einschließen.
Dieses Beispiel zeigt, wie Sie Scheduler für logische Schnittstellen mithilfe von Datenverkehrssteuerungsprofilen definieren.
Konfiguration
CLI-Schnellkonfiguration
Um dieses Beispiel schnell zu konfigurieren, kopieren Sie die folgenden Befehle, fügen sie in eine Textdatei ein, entfernen alle Zeilenumbrüche, ändern alle erforderlichen Details, um mit Ihrer Netzwerkkonfiguration zu übereinstimmen, und kopieren Sie dann die Befehle und fügen sie auf Hierarchieebene in die [edit] CLI ein.
