请问哪位大佬有流统的实例呀，麻烦分享一下呗

问题背景：

client(1.1.1.1)-----------g1/0/1--sw1--g1/0/2------------g1/0/1--sw2--g1/0/2-----------server(2.2.2.2)

 

client ping server 有丢包，需通过流量统计确定丢包位置

 

SW1和SW2配置一样，仅以SW1举例

1：定义一个acl，用来匹配测试的流量，假设用ping包去测试：

<H3C>sys

[H3C]acl advanced 3998                                                                                       //定义一个高级acl，编号可自行替换

[H3C-acl-ipv4-adv-3998]rule permit icmp source 1.1.1.1  0 destination 2.2.2.2  0                //匹配源是1.1.1.1到目的2.2.2.2的ping包

[H3C-acl-ipv4-adv-3998]rule permit icmp source 2.2.2.2  0 destination 1.1.1.1  0                //匹配回包

[H3C-acl-ipv4-adv-3998]qu

[H3C]

 

2：定义流分类、流行为、以及qos策略

[H3C]traffic classifier abc                                //定义流分类abc，abc可自定义去替换

[H3C-classifier-abc]if-match acl 3998        //关联此前定义的acl3998，以实际为主去替换

[H3C-classifier-abc]qu

[H3C]

[H3C]traffic behavior abc                                //定义流行为abc，abc可自定义去替换，不必与流分类的名字保持一致

[H3C-behavior-abc]accounting packet         //动作为统计

[H3C-behavior-abc]qu

[H3C]

[H3C]qos policy abc                        //定义 qos策略来关联流分类和流行为

[H3C-qospolicy-abc]classifier abc behavior abc

[H3C-qospolicy-abc]qu

[H3C]

 

3：相关接口下应用qos流统策略，如果是聚合口，需要在聚合口的所有成员接口下发，可使用dis link-agg ver确认聚合口的成员接口是那些

[H3C]inter GigabitEthernet 1/0/1                                                //进入相关接口去应用qos

[H3C-GigabitEthernet1/0/1]qos apply policy abc inbound                 //入方向应用qos

[H3C-GigabitEthernet1/0/1]qos apply policy abc outbound                 //出方向应用qos

[H3C-GigabitEthernet1/0/1]qu

[H3C]inter GigabitEthernet 1/0/2                                              //进入相关接口去应用qos

[H3C-GigabitEthernet1/0/2]qos apply policy abc inbound                 //入方向应用qos

[H3C-GigabitEthernet1/0/2]qos apply policy abc outbound                 //出方向应用qos

[H3C-GigabitEthernet1/0/2]qu

 

[H3C]                                                                        //client开启ping测试，记录好ping测结果

[H3C]dis qos policy interface                                          //完成后 查看交换机接口的统计结果

Interface: GigabitEthernet1/0/1

  Direction: Inbound

  Policy: abc

   Classifier: abc

     Operator: AND

     Rule(s) :

      If-match acl 3998

     Behavior: abc

      Accounting enable:

        0 (Packets)

 

Interface: GigabitEthernet1/0/1

  Direction: Outbound

  Policy: abc

   Classifier: abc

     Operator: AND

     Rule(s) :

      If-match acl 3998

     Behavior: abc

      Accounting enable:

        0 (Packets)

 

 

4：清空已有的流量统计结果
