Access-list 10 permit 202.112.162.5
Ip http server
Ip http access-list 10
在客户机202.112.162.5中,用网页下载工具wget定期采集、清除IP流量。方法如下:
#读取IP流量,存入outpu-packets网页文件中
wget --http-user=admin --http-passwd=cisco
http://cisco/exec/show/ip/accounting/output-packets
#清除采集过的IP流量
wget --http-user=admin --http-passwd=cisco
http://cisco/exec//clear/ip/accounting/CR
在网页outpu-packets中,读取标识符、
之间的IP流量表,来实现统计IP流量。
