小巧的丢包方法

在连接pc两端的交换机上配置。

定义ACL

acl number 3000

rule 5 permit icmp source 192.168.2.7 0 destination 192.168.1.254 0

acl number 3001

rule 5 permit icmp source 192.168.1.254 0 destination 192.168.2.7 0

匹配ACL

traffic classifier 1 operator and

if-match acl 3000

traffic classifier 2 operator and

if-match acl 3001

统计流

traffic behavior 1

statistic enable

traffic behavior 2

traffic policy 100

classifier 1 behavior 1

traffic policy 200

classifier 2 behavior 2

应用到接口

interface GigabitEthernet0/0/5

traffic-policy 100 inbound

traffic-policy 200 outbound

interface GigabitEthernet0/0/23

traffic-policy 200 inbound

traffic-policy 100 outbound

ping 192.168.1.254

C:UsersAdministrator>ping 192.168.1.254

正在 Ping 192.168.1.254 具有 32 字节的数据:

来自 192.168.1.254 的回复: 字节=32 时间=1ms TTL=128

查看转发的数据包

dis traffic policy statistics interface g0/0/5 inbound

dis traffic policy statistics interface g0/0/5 outbound

dis traffic policy statistics interface g0/0/23 inbound

dis traffic policy statistics interface g0/0/23 outbound

分别在多台设备上查看流量来计算丢包在那里，丢包率多少。（reset没有找到清空的选项，比较简单的清空统计方法就是接口下undo掉 traffic-policy然后再应用下。
