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
IPV4 SRC ADDR IPV4 DST ADDR bytes long pkts long
