Answered Question
Sep 8th, 2008

Hi,

Does anyone know someway to see in the router wich IP address is generating more traffic?

With nbar I can see wich protocol is loading the link but not the IP who is doing this.

I would like to know if I can do that with only the router cli, with no external server.

Thanks

I have this problem too.

Hi.

You can use Netflow for the ingress or IP accounting for checking egress

Netflow:

interface FastEthernet0/0

ip flow ingress

show ip cache flow

IP Accounting:

interface FastEthernet0/0

ip accounting

show ip accounting

Hi

you can make use of netflow to check the same.

you need to enable ip route-cache flow under the ethernet interface and can check the traffic pattern using show ip cache flow command.

The output will give u a clear idea about the source/destination port/ip address packet counts to identify the utilization pattern.
