查看 cisco 路由器的 IP 流量
Csico 路由器有时需要定位到某个高流量的 IP 地址，但是交换机模块的端口是没办法查看
到具体 IP，只能通过出口来进行流量查看
步骤 1：将流量计数应用到路由出口
zz#conf t
zz(cong)#
zz(cong)#int fastEthernet 0/0
zz(cong-if)#ip accounting
步骤 2：查看端口流量计数
zz#sh ip accounting

182.118.124.204 172.16.11.206 5 1099
至此可以查看对应的内网 IP 地址哪个流量高
为了准确判断，在查看前最好能清除一下计数
zz#clear ip accounting
zz#sh ip accounting
