H3C 路由器 QoS 的CBQ配置

CBQ的配置

【需求】

路由器执行染色并执行cbq

对内网发过来的数据包染色

数据包分类：

为方便运行维护管理，供QoS使用的访问控制列表号码统一规范为下述命令中的号码

acl n 3181        //视频业务

…….

acl n 3182        //关键业务1

……

acl n 3183        //关键业务2

…….

acl n 3184        //关键业务3

……

acl n 3185        //信息网站

……….

acl n 3186        //下载业务

…………

acl n 3187        //其他业务

………….

 

根据上面acl对路由器接收到的不同类型的数据包标记不同的dscp值：

[Quidway]traffic classifier VideoAudio

[Quidway-classifier-VideoAudio]if-match acl 3181

[Quidway]traffic classifier Critical-1

[Quidway-classifier- Critical-1] if-match acl 3182

[Quidway]traffic classifier Critical-2

[Quidway-classifier- Critical-2] if-match acl 3183

[Quidway]traffic classifier Critical-3

[Quidway-classifier- Critical-3] if-match acl 3184

[Quidway]traffic classifier Information

[Quidway-classifier- Information] if-match acl 3185

[Quidway]traffic classifier Quantity

[Quidway-classifier- Quantity] if-match acl 3186

[Quidway]traffic classifier default

[Quidway-classifier-default] if-match acl 3187

 

定义染色的动作:

//语音视频业务

[Quidway]traffic behavior VideoAudio

[Quidway-behavior-VideoAudio]remark dscp 46

//关键业务1

[Quidway]traffic behavior Critical-1

[Quidway-behavior-Critical-1]remark dscp 34

//关键业务2

[Quidway]traffic behavior Critical-2

[Quidway-behavior-Critical-2]remark dscp 26

//关键业务3

[Quidway]traffic behavior Critical-3

[Quidway-behavior-Critical-3]remark dscp 35

//信息网站

[Quidway]traffic behavior Information

[Quidway-behavior-Information]remark dscp 18

//批量业务

[Quidway]traffic behavior Quantity

[Quidway-behavior-Quantity]remark dscp 10

//其它业务

[Quidway]traffic behavior default

[Quidway-behavior-default]remark dscp 0

 

对本地交换机快速以太网接口上行包染色:

[Quidway]#qos policy RS_down_local //至本地交换机快速以太网接口

[Quidway-qospolicy-RS_down_local]class VideoAudio behavior VideoAudio2

[Quidway-qospolicy-RS_down_local]class Critical-1 behavior Critical-1

[Quidway-qospolicy-RS_down_local]class Critical-2 behavior Critical-2

[Quidway-qospolicy-RS_down_local]class Information behavior Information

[Quidway-qospolicy-RS_down_local]class Quantity behavior Quantity

[Quidway-qospolicy-RS_down_local]class default behavior default

策略应用：

在相应的端口应用相应的QOS保障策略

[Quidway]int 端口(至本地交换机)

[Quidway-端口]qos apply policy RS_down_local in

对符合染色定义的包执行cbq

根据本规范中第2.1.2小节定义，对路由器接收到的不同优先级的数据包，划分不同的服务类别：

[Quidway]traffic classifier VideoAudio2

[Quidway-classifier-VideoAudio]if-match dscp 46

[Quidway]traffic classifier Critical-12

[Quidway-classifier- Critical-1]if-match dscp 34

[Quidway]traffic classifier Critical-22

[Quidway-classifier- Critical-2]if-match dscp 26

[Quidway]traffic classifier Critical-32

[Quidway-classifier- Critical-3]if-match dscp 35

[Quidway]traffic classifier Information2

[Quidway-classifier- Information]if-match dscp 18

[Quidway]traffic classifier Quantity2

[Quidway-classifier- Quantity]if-match dscp 10

[Quidway]traffic classifier default2

[Quidway-classifier-default]if-match dscp 0

  策略定义：

针对不同的链路出口定义不同的策略

 

至省会X的主线路接口:

//语音视频业务

[Quidway]traffic behavior VideoAudio2

[Quidway-behavior-VideoAudio2]queue af bandwidth 800

//关键业务1

[Quidway]traffic behavior Critical-12

[Quidway-behavior-Critical-12]queue ef bandwidth pct 10

[Quidway-behavior-Critical-12]wred dscp
