交換機涉及丟包問題 進行流量統計 配置參考
解決方案
關鍵配置如下：
#
acl number 3000
rule 0 permit icmp source 192.168.1.2 0 destination192.168.1.3 0
rule 1 permit icmp source 192.168.1.3 0 destination 192.168.1.2 0 //需要統計的流量,源做目的,目的做源.需要正反寫兩條rule條目
#
traffic classifier 3000 operator and
if-match acl 3000
#
traffic behavior 3000
permit
statistic enable
// 在流行爲中 開啓流量統計功能 statistic enable
#
traffic policy 3000
classifier 3000 behavior 3000
#
interface gigabitEthernet0/0/1
// 在流量的進入交換機的接口和出交換機的接口上都要雙方向調用流策略
traffic-policy 3000 inbound
traffic-policy 3000 outbound
#
interface gigabitEthernet0/0/2
//在流量的進入交換機的接口和出交換機的接口上都要雙方向調用流策略
traffic-policy 3000 inbound
traffic-policy 3000 outbound
#

入接口GigabitEthernet 0/0/1 inbound 方向通過的數據包個數 等於出接口GigabitEthernet 0/0/2 outbound方向通過的數據包個數，表明ping的請求包交換機沒有丟包
入接口GigabitEthernet 0/0/1 outbound 方向通過的數據包個數 等於出接口GigabitEthernet 0/0/2 inbound方向通過的數據包個數，表明ping的回包交換機沒有丟包
