Exemple: Configuration de CoS sur EX Series commutateurs
Configurez classe de service (CoS) sur votre commutateur pour gérer le trafic de manière à ce que les applications critiques soient protégées en cas d’encombrement et de délai du réseau. Grâce CoS, vous pouvez diviser le trafic de votre commutateur en classes et fournir différents niveaux de débit et de perte de paquets. Cela est particulièrement important pour le trafic sensible à la gigue et aux délais, tels que les trafics voix.
Cet exemple montre comment configurer une CoS sur un seul commutateur EX Series réseau.
Exigences
Cet exemple utilise les composants matériels et logiciels suivants:
Commutateurs d’EX4200 ex3200 et de commutateurs
Junos OS version 9.0 ou ultérieure pour les EX Series commutateurs
Présentation et topologie
Cet exemple s’appuie sur la topologie de la figure 1.
Figure 1: Topologie de configuration des CoS
La topologie de cet exemple de configuration se compose de commutateurs ex3200 EX4200 au niveau de la couche d’accès.
Les EX Series d’accès sont configurés pour prendre en charge l’adhésion au VLAN. Sur le commutateur de couche d’accès EX3200, des interfaces sont attribuées au VLAN vocal ( ) pour deux téléphones ge-0/0/0 ge-0/0/1 IP voice-vlan VoIP. L’interface ge-0/0/2 du commutateur est affectée à la caméra VLAN camera-vlan () pour la caméra de surveillance. Interfaces de commuter , et sont assignées au serveur VLAN ( ) pour les serveurs hébergeant diverses applications, telles que celles fournies par ge-0/0/3 ge-0/0/4 ge-0/0/5 ge-0/0/6 server-vlan Citrix, Microsoft, Oracle et SAP. Les ports du tronc de l’EX3200, ge-0/0/20 et ge-0/0/21, sont assignés aux réseaux VLAN serveur, voix, employé et caméra et utilisés comme ports de liaison pour connecter les commutateurs de la couche de distribution.
EX4200 commutateurs d’accès sont également inclus dans la couche d’accès pour connecter de la même manière les réseaux VLA de l’employé et de la voix, même si cet exemple n’indique pas les détails de configuration de ces commutateurs.
Le tableau 1 montre les composants de configuration VLAN.

PoE ports sur les commutateurs EX Series prendre en charge Power over Ethernet (PoE) afin d’assurer à la fois la connectivité réseau et l’alimentation des téléphones VoIP qui se connectent aux ports. Le tableau 2 montre les interfaces de commuter attribuées aux VLAN et les adresses IP des équipements connectés aux ports du commutateur sur un commutateur à 48 ports, tous les ports PoE capacité.

Remarque:
Cet exemple montre comment configurer CoS sur un commutateur d’EX Series autonome. Cet exemple ne prend pas en compte les applications réseau de CoS dans lesquelles vous pouvez implémenter différentes configurations sur les commutateurs d’entrée et de sortie afin de fournir un traitement différencié aux différentes classes d’un ensemble de nodes d’un réseau.
Remarque:
Même si vous voyez parfois des scheduleurs configurés pour une priorité strictement élevée avec un débit d’émission configuré, cette configuration est trompeuse, car les planningurs à priorité élevée stricte disposent d’une bande passante illimitée et les paramètres de ce dernier n’ont aucun effet sur eux. Avec cette configuration, les files d’attente de faible priorité peuvent être victimes d’une saturation en cas d’encombrement. Mieux vaut configurer des paramètres de mise en forme prioritaires pour limiter leur bande passante.

Vérification
Pour vérifier que la configuration fonctionne correctement, exécutez les tâches suivantes:
- Vérification de l’existence des classes de forwarding définies et de leur intérêt pour les files d’attente
- Vérifier que les classes de forwarding ont été attribuées aux planningurs
- Vérification de l’application de la carte de planning sur les interfaces
- Vérification de l’application de la mise en forme des ports
- Vérification de l’application de la mise en file d’attente
