此配置只适合分配好VLAN的各项业务，例如：vlan10是视频业务，vlan20是语音业务等。

1.配置流分类

[ar1]traffic classifier c1 operator and	
[ar1-classifier-c1]if-match vlan-id 10
[ar1-classifier-c1]q
[ar1]traffic classifier c2 operator and	
[ar1-classifier-c2]if-match vlan-id 20
[ar1-classifier-c2]q

2.配置流行为

• 业务对实时性要求比较高，设置大带宽的同时，将DSCP优先级标记为46，保证后续设备优先转发。
• 对实时性要求没语音那么敏感，可以配置大带宽，将DSCP优先级标记为30。

[ar1]traffic behavior b1
[ar1-behavior-b1]car cir 8000 pir 15000  //配置限速带宽
[ar1-behavior-b1]remark dscp 46	   //标记报文DSCP为46
[ar1-behavior-b1]statistic enable   //用于验证配置结果
[ar1-behavior-b1]q
[ar1]traffic behavior b2
[ar1-behavior-b2]car cir 10000 pir 20000
[ar1-behavior-b2]remark dscp 30	
[ar1-behavior-b2]statistic enable
[ar1-behavior-b2]q

3.配置流策略

[ar1]traffic policy p1
[ar1-trafficpolicy-p1]cha	
[ar1-trafficpolicy-p1]cl	
[ar1-trafficpolicy-p1]classifier c1 be	
[ar1-trafficpolicy-p1]classifier c1 behavior b1
[ar1-trafficpolicy-p1]cl	
[ar1-trafficpolicy-p1]classifier c2 be	
[ar1-trafficpolicy-p1]classifier c2 behavior b2

4.应用至接口

[ar1]int g0/0/0	
[ar1-GigabitEthernet0/0/0]traffic-policy p1 inbound 
[ar1-GigabitEthernet0/0/0]q
