S5120组了内外网并用网关ping不通

流量统计看看包是谁丢的

端口流量统计

配置设备的流量统计，对端口的进出数据包进行统计

交换机上配置：

#

acl number 3000  //匹配  源192.168.1.1，目的192.168.1.3

 rule 0 permit icmp source 192.168.1.1 0 destination 192.168.1.3 0

acl number 3001   //匹配 源192.168.1.3，目的 192.168.1.1

 rule 0 permit icmp source 192.168.1.3 0 destination 192.168.1.1 0

 qos apply policy 2 inbound   //192.168.1.3→192.168.1.1进端口

 qos apply policy 1 outbound  //192.168.1.1→192.168.1.3出端口

Ping之前直接要先清空设备接口的统计：

<H3C>Reset counters interface

在192.168.1.1 ping 192.168.1.3   4个包
