H3C交换机进行流统，需要怎么配置

[H3C]acl number 3333

[H3C-acl-adv-3333]description traffic accounting for host A to host B

[H3C-acl-adv-3333]rule 10 permit tcp source 1.1.1.1 0.0.0.0 destination 2.2.2.2 0.0.0.0 destination-port eq 80

定义流分类，匹配acl定义的PCA访问PCB的web流量。

[H3C]traffic classifier traffic_accounting_from_A_to_B

[H3C-classifier-traffic_accounting_from_A_to_B]if-match acl 3333

定义流行为，统计报文个数

[H3C]traffic behavior traffic_accounting_from_A_to_B

[H3C-behavior-traffic_accounting_from_A_to_B]accounting packet

定义qos策略，关联流分类和流行为

[H3C]qos policy traffic_accounting_from_A_to_B

[H3C-qospolicy-traffic_accounting_from_A_to_B]classifier traffic_accounting_from_A_to_B behavior traffic_accounting_from_A_to_B

在2/0/1的入方向和2/0/2的出访问下发qos策略，来统计报文是否到达设备和是否被设备转发给PCB。

[H3C]interface GigabitEthernet2/0/1

[H3C-GigabitEthernet2/0/1]qos apply policy traffic_accounting_from_A_to_B inbound

[H3C]interface GigabitEthernet2/0/2

[H3C-GigabitEthernet2/0/2]qos apply policy traffic_accounting_from_A_to_B outbound

使PCA访问PCB，查看接口GigabitEthernet2/0/1流量统计结果

[H3C]display qos policy interface GigabitEthernet 2/0/1

  Interface: GigabitEthernet2/0/1

  Direction: Inbound

  Policy: traffic_accounting_from_A_to_B
   Classifier: traffic_accounting_from_A_to_B
     Operator: AND
     Rule(s) : If-match acl 3333
     Behavior: traffic_accounting_from_A_to_B
      Accounting Enable:
