在路由器上使用模块化QOS命令行(MQC,12.2T),配置分为三部分:class-map:对流量分类policy-map:对每类流量分配queue,priority关键字表示使用LLQ。server-policy:将policy-map绑定到接口上。

  五、WAN Qos配置与远程办公室Qos配置

  在路由器上使用模块化QOS命令行(MQC,12.2T),配置分为三部分:

  class-map:对流量分类

  policy-map:对每类流量分配queue,priority关键字表示使用LLQ。

  server-policy:将policy-map绑定到接口上。

  1、Policy-map配置

  class-map match-all VOICE

  match ip dscp ef

  class-map match-all VIDEO

  match ip dscp af41

  class-map match-all VOICE-CONTROL

  match ip dscp af31

  class-map match-any GOLD-DATA

  match ip dscp af21

  match ip dscp af22

  match ip dscp af23

  class-map match-any SILVER-DATA

  match ip dscp af11

  match ip dscp af12

  match ip dscp af13

  !

  policy-map WAN-EDGE

  class VOICE

  priority percent 17

  class VIDEO

  priority percent 16 30000
