例: デバイスでのCoSのEX シリーズ スイッチ
スイッチサービス クラス(CoS)を設定してトラフィックを管理し、ネットワークの輻輳と遅延が発生した場合に、重要なアプリケーションを保護します。このCoSを使用して、スイッチ上のトラフィックをクラスに分割し、さまざまなレベルのスループットとパケット ロスを提供できます。これは、音声トラフィックなど、ジッターや遅延に敏感なトラフィックにとって特に重要です。
この例では、ネットワーク内の単一CoSスイッチ上でEX シリーズ設定する方法を示しています。
要件
この例では、次のハードウェアとソフトウェアのコンポーネントを使用しています。
EX3200 およびEX4200スイッチ
Junos OS スイッチ用のJunos OS リリース 9.0 EX シリーズ
概要とトポロジー
この例では、図 1 に示すトポロジー を使用しています。
図 1:設定時のトポロジCoS
この設定例のトポロジーは、アクセス レイヤーの EX3200 EX4200 スイッチで構成されています。
VLAN EX シリーズ スイッチは、VLAN メンバーシップをサポートするように設定されています。EX3200アクセスレイヤースイッチでは、2つのVoIP IP電話のインターフェイスと、voice VLAN( )に ge-0/0/0 ge-0/0/1 voice-vlan 割り当てられます。スイッチインターフェイス ge-0/0/2 は、監視カメラのカメラVLAN( ) camera-vlan に割り当てられます。スイッチ インターフェイス ge-0/0/3 、 ge-0/0/4 )を ge-0/0/5 ge-0/0/6 server-vlan 、Citrix、Microsoft、Oracle、SAP が提供するアプリケーションなど、さまざまなアプリケーションをホストするサーバー用に、サーバー VLAN( )に割り当てられます。EX3200 トランク ポート ge-0/0/20 および ge-0/0/21 は、サーバー、音声、従業員、カメラの VLAN に割り当てられます。アップリンク ポートとして使用して、ディストリビューション レイヤー スイッチに接続します。
EX4200スイッチもアクセス レイヤーに含まれており、従業員と音声の VLAN を同様に接続しますが、この例ではこれらのスイッチの設定の詳細は示していません。

注:
この例では、スタンドアロンのスイッチ上でCoS設定する方法EX シリーズしています。この例では、ネットワーク内のノード セット全体で異なるクラスに差別化処理を提供するためにイングレス/エグレス スイッチに異なる設定を実装する場合に、CoS のネットワーク全体のアプリケーションを考慮する必要はありません。
注:
送信レートが設定されたス厳優先に設定されたスケジューラが表示される場合もあります。しかし、スレートが高い優先度のスケジューラは無制限の帯域幅を持ち、送信レート パラメータは影響を与えないので、その設定は誤解を招くでしょう。この設定では、輻輳が発生すると、優先度の低いキューが使用しきれなくなります。優先度が厳しいスケジューラでシェーピングレート パラメータが設定されている方が、帯域幅を制限する正しい方法であるより良いです。
構成
手順
CLI迅速な設定
CoSを迅速に設定するには、以下のコマンドをコピーして、スイッチ端末ウィンドウに貼り付けます。

- 定義された転送クラスが存在し、キューにマッピングされている検証
- 転送クラスがスケジューラに割り当てられていないかの検証
- インターフェイスにスケジューラ マップが適用された検証
- ポート シェーピングが適用された検証
- キュー シェーピングが適用された検証
