1  簡介

本文檔介紹了重標記、優先級映射與隊列調度的配置舉例。

重標記是將報文的優先級或者標誌位進行設置，重新分配報文的優先級值等。

隊列調度是指當設備的某個端口發生擁塞時，先通過配置隊列調度策略修改各隊列的調度參數，然後在該端口應用該策略來實現擁塞管理功能。

2  配置前提

本文檔中的配置均是在實驗室環境下進行的配置和驗證，配置前設備的所有參數均采用出廠時的缺省配置。如果您已經對設備進行了配置，為了保證配置效果，請確認現有配置和以下舉例中的配置不衝突。

本文假設您已了解隊列調度特性。

3  使用限製

dscp/exp/dot1p/lp/dp重標記與下列QoS動作衝突：流量過濾（filter deny命令）、重定向到CPU（redirect cpu命令）以及帶顏色的報文優先級映射（primap命令）。

4  重標記與隊列調度典型配置舉例

4.1  組網需求

如圖1所示，某公司在省內各市和省中心之間通過雙上行鏈路互連，公司內網的業務分為以下三種：

·            視頻相關業務：使用IP網段10.1.0.0/16（其中省中心內網使用IP網段10.1.1.0/24；A市內網使用IP網段10.1.2.0/24……F市內網使用IP網段10.1.7.0/24）；

·            生產相關業務：使用IP網段10.2.0.0/16（其中省中心內網使用IP網段10.2.1.0/24；A市內網使用IP網段10.2.2.0/24……F市內網使用IP網段10.2.7.0/24）；

·            語音相關業務：使用IP網段10.3.0.0/16（其中省中心內網使用IP網段10.3.1.0/24；A市內網使用IP網段10.3.2.0/24……F市內網使用IP網段10.3.7.0/24）。

現要求通過配置隊列調度策略實現當網絡發生擁塞時，三種業務（視頻相關業務：生產相關業務：語音相關業務）之間按照調度比重2：1：1的權重進行調度。

圖1 配置組網圖

 

4.2  配置思路

由於本例中三種業務均為IP業務，為了將三種業務流量入不同的隊列，可以重新標記報文的本地優先級，將不同的業務流量指定至對應的隊列中。

當發生擁塞時，若要實現三種業務按照2：1：1的權重比例進行調度，需要將三種業務規劃到同一WRR優先組的不同隊列中。在本例中指定視頻業務為隊列2，生產業務為隊列3，語音業務為隊列4（缺省情況下，端口輸出隊列的調度方式為SP隊列），並通過配置指定隊列的調度策略來實現三個隊列之間的調度權重比為2：1：1。

4.3  配置步驟

4.3.1  Device S1的配置

 

(1)       在內網入端口區分不同業務的流量進入不同的隊列
