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

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.
