如何配置流量统计功能
假设电脑192.168.1.2在ping路由器192.168.1.1时丢包,想确认中间的交换机转发报文是否有问题,可以在交换机上做流量统计进行准确确认。
网络拓扑示例图如下:
在中间的交换机上做流量统计的步骤如下:
一、配置流量统计功能
1、从用户视图切换到系统视图
<Huawei>system-view
2、创建ACL3333匹配ping请求报文,ACL3334匹配ping响应报文
[Huawei]acl 3333
[Huawei-acl-adv-3333]rule 5 permit icmp source 192.168.1.2 0 destination 192.168.1.1 0
[Huawei-acl-adv-3333]quit
[Huawei]acl 3334
[Huawei-acl-adv-3334] rule 5 permit icmp source 192.168.1.1 0 destination 192.168.1.2 0
[Huawei-acl-adv-3334]quit
3、配置流分类,引用前面配置的ACL规则
[Huawei]traffic classifier test1
[Huawei-classifier-test1] if-match acl 3333
[Huawei-classifier-test1]quit
[Huawei]traffic classifier test2
[Huawei-classifier-test2] if-match acl 3334
[Huawei-classifier-test2]quit
4、配置流行为,启用计数功能
[Huawei]traffic behavior test1
[Huawei-behavior-test1]statistic enable
[Huawei-behavior-test1]quit
[Huawei]traffic behavior test2
[Huawei-behavior-test2]statistic enable
[Huawei-behavior-test2]quit
5、配置流策略,将流分类和流行为关联
[Huawei]traffic policy test1
[Huawei-trafficpolicy-test1]classifier test1 behavior test1
[Huawei-trafficpolicy-test1]quit
[Huawei]traffic policy test2
[Huawei-trafficpolicy-test2]classifier test2 behavior test2
[Huawei-trafficpolicy-test2]quit
6、在连接电脑的接口上应用流策略
[Huawei]interface GigabitEthernet 0/0/2
[Huawei-GigabitEthernet0/0/2]traffic-policy test1 inbound
[Huawei-GigabitEthernet0/0/2]traffic-policy test2 outbound
[Huawei-GigabitEthernet0/0/2]quit
7、在连接路由器的接口上应用流策略
[Huawei]interface GigabitEthernet 0/0/1
[Huawei-GigabitEthernet0/0/1]traffic-policy test2 inbound
[Huawei-GigabitEthernet0/0/1]traffic-policy test1 outbound
[Huawei-GigabitEthernet0/0/1]quit
二、测试并查看统计结果
(1)用电脑192.168.1.2去ping路由器192.168.1.1。
(2)查看统计结果
查看ping请求:
display traffic policy statistics interface GigabitEthernet 0/0/2 inbound
display traffic policy statistics interface GigabitEthernet 0/0/1 outbound
查看ping响应:
display traffic policy statistics interface GigabitEthernet 0/0/1 inbound
display traffic policy statistics interface GigabitEthernet 0/0/2 outbound
查看结果示例如下(以ping10个包为例):
上面是查看对ping请求报文转发的结果。结果表明,收到10个报文,并转发了10个报文
上面是查看对ping响应报文转发的结果。结果表明,收到10个报文,并转发了10个报文
附:如果想在下次统计前清除之前的结果,可以使用以下命令进行清除统计计数(注意:需要在用户视图下操作)。
reset traffic policy statistics interface GigabitEthernet 0/0/2 inbound
reset traffic policy statistics interface GigabitEthernet 0/0/1 outbound
reset traffic policy statistics interface GigabitEthernet 0/0/1 inbound
reset traffic policy statistics interface GigabitEthernet 0/0/2 outbound
