思科4431/4331路由器接口下查看通信对流量

第一步：建立记录

WH-ZYL-DX#conf t
WH-ZYL-DX(config)#flow record recordname1
WH-ZYL-DX(config-flow-record)#match ipv4 source address
WH-ZYL-DX(config-flow-record)#match ipv4 destination address
WH-ZYL-DX(config-flow-record)#collect counter packets/bytes long
WH-ZYL-DX(config-flow-record)#exit

第二步：建立检测，并关联记录
WH-ZYL-DX(config)#flow monitor monitorname1
WH-ZYL-DX(config-flow-monitor)#record recordname1
WH-ZYL-DX(config-flow-monitor)#cache timeout active 604800
WH-ZYL-DX(config-flow-monitor)#cache entries 200000
WH-ZYL-DX(config-flow-monitor)#exit
WH-ZYL-DX(config)#end

第三步：接口下调用

WH-ZYL-DX#conf t
WH-ZYL-DX(config)#int Se0/1/0
WH-ZYL-DX(config-if)#ip flow monitor monitorname1
input Apply Flow Monitor on input traffic
multicast Apply Flow Monitor on multicast traffic
output Apply Flow Monitor on output traffic
sampler Optional Sampler to apply to this Flow Monitor
unicast Apply Flow Monitor on unicast traffic

WH-ZYL-DX(config-if)#ip flow monitor monitorname1 input
WH-ZYL-DX(config-if)#end

第四步：查看流量情况
WH-ZYL-DX#sh flow monitor monitorname1 cache
