I have several different locations (Cities) on my network. Each 3rd octet (x.x.3rd.x) is a separate network (See chart below). The issue I'm having is when I look at my top talkers in Netflow v5 I see traffic from all my networks combined. I'd would only like to only see traffic that pertains to the 3rd octet. Is there anyway of setting up in the Cisco router or in PRTG to drill down and only see the network I setup per sub net?
