Hi, in this case I fully agree with Armin's advice, only wanted to provide a possible way to archive an easy result without activation of netflow/sflow which is possible if all subnets had dedicated ports somewhere in the net.
I don't know what information you want to get from your routers, as there are many ways to get a result depending on the information you want and the used vendors. Regards Karsten Am Dienstag, 17.
