I am new to setting this up so it may be obvious but I couldnt find a solution yet.

I have added a single sensor netflow 5 in to PRTG which monitors traffic on my cisco 1941 interface E0/0 and this is working fairly well, but I want to seperately monitor interface 0/1.100 and interface 0/1.110 , is this possible to get the traffic seperately if I add ip flow to those interfaces or will it all just be bundled into the one sensor?

Hello,

thank you very much for your KB-Post. Basically there are two options for this. Either set different flow exports, so one for each interface, and then use two Netflow Sensors each listening on a different UDP port.
Or use one flow export for all / both interfaces, and then two Netflow Sensors listening on the same port. But the Netflow Sensors then use Filters on the sensors, so that each one filters for one interface.

best regards.

thanks I thought filters might do it but that gives me another option too.
