过设备ping有丢包,流统看丢在设备上
28口和51口都在聚合口中,现场设做了堆叠,手动down掉备框的口了

连接服务器的口有softcar arp丢包的信息原则上不影响28口转发

PC的mac,有mac飘移,服务器的mac没有看到飘移

于是接口静态绑定mac测试,也有丢包情况

此时重新ping测试,做接口和全局流统。
可以看到接口有两个包没法出去。
然后全局流统统计到了这两个包,端口优先级更高,说明是从端口进来10个,然后从端口出去8个,还有俩从其他端口走了,然后全局流统就统计到了 。
于是查看设备上up的口有多少,把流统下发到这些端口,看下没有从正确接口出去的报文从哪个接口发出去了。
对所有UP接口下发流统,找到了对应的两个异常接口。
Interface: GigabitEthernet1/0/25
Direction: Outbound
Policy: 1
Classifier: 1
Operator: AND
Rule(s) :
If-match acl 3001
Behavior: 1
Accounting enable:
1 (Packets)
Interface: GigabitEthernet1/0/26
Direction: Outbound
Policy: 1
Classifier: 1
Operator: AND
Rule(s) :
If-match acl 3001
Behavior: 1
Accounting enable:
1 (Packets)
Shutdown对应接口后,流量转发正常。
接口连接的第三方服务器问题。
