一 交换机流统技术介绍交换机流量统计的核心作用是帮你精确掌握特定流量在接口上的收发情况从而快速定位故障、排查丢包或者业务不通问题。这是最常用的场景。当设备之间ping不通或业务卡顿时在交换机上配置针对ICMPping报文的流量统计对比接口入方向和出方向的计数如果入方向收到但出方向没发出去说明报文在交换机上丢了故障点就在这台设备。如果接口发出的报文比对端收到的多说明链路中间丢了包需要在对端设备上继续配置统计来缩小范围。二 组网如下三 流统配置#acl advanced 3000description LiuTongrule 0 permit ip source 192.168.1.2 0 destination 192.168.2.2 0rule 5 permit ip source 192.168.2.2 0 destination 192.168.1.2 0#traffic classifier 1 operator andif-match acl 3000#traffic behavior 1accounting packet#qos policy 1classifier 1 behavior 1#interface GigabitEthernet1/0/1qos apply policy 1 inboundqos apply policy 1 outbound#interface GigabitEthernet1/0/2qos apply policy 1 inboundqos apply policy 1 outbound#流统参数可以配置基于字节数统计或者基于包数统计[HX-behavior-1]accounting ?byte Accounting in bytespacket Accounting in packets[HX-behavior-1]accounting四 业务测试PC1ping -c 5 192.168.2.2Ping 192.168.2.2 (192.168.2.2): 56 data bytes, press CTRLC to break56 bytes from 192.168.2.2: icmp_seq0 ttl254 time1.090 ms56 bytes from 192.168.2.2: icmp_seq1 ttl254 time0.727 ms56 bytes from 192.168.2.2: icmp_seq2 ttl254 time0.674 ms56 bytes from 192.168.2.2: icmp_seq3 ttl254 time0.651 ms56 bytes from 192.168.2.2: icmp_seq4 ttl254 time0.873 ms五 状态查看[HX][HX]dis qos policy interfaceInterface: GigabitEthernet1/0/1Direction: InboundPolicy: 1Classifier: 1Operator: ANDRule(s) :If-match acl 3000Behavior: 1Accounting enable:5 (Packets)Interface: GigabitEthernet1/0/1Direction: OutboundPolicy: 1Classifier: 1Operator: ANDRule(s) :If-match acl 3000Behavior: 1Accounting enable:5 (Packets)Interface: GigabitEthernet1/0/2Direction: InboundPolicy: 1Classifier: 1Operator: ANDRule(s) :If-match acl 3000Behavior: 1Accounting enable:5 (Packets)Interface: GigabitEthernet1/0/2Direction: OutboundPolicy: 1Classifier: 1Operator: ANDRule(s) :If-match acl 3000Behavior: 1Accounting enable:5 (Packets)[HX]
