Feature Request

rlawsha

Something I could really use in netflow is to be able to see who the top talkers are for a particular subnet. I need to look at 10.18.*.* for instance and see which ip addresses are using the most bandwidth.

AHA! I've just discovered where to setup IP Address Groups. This may be the solution.....

You could use Netflow Ip address Groups for this. You can setup the subnet a a group and filter by that group.

Thanks for the info. I have been trying to figure out that feature with no luck. Exactly how do you do that? When I go into NetFlow and click on an interface I get a summary page, Top 5 Protocols, Top 10 Endpoints, Top 10 Applications and the like but no IP Address Groups section.

Did you find a solution to this problem? I'm also interested in finding the top talker(s) on a subnet?

Hi,

we have resource for IP Address Group for interface detail view, but it's not there by default. You need to customize view and add resource [Top XX IP Address Groups].

Or other possibility is to create query by [Traffic Builder]. On NTA Summary View you should have resource [Traffic View Builder]. You can choose Node, Interface and there you can add filter for specific IP Address Group.

Is this what you need?

Regards

ET,

Thanks for the reply (I seem to be working you hard today!)

I tried to use Traffic View Builder but I couldn't seem to restrict the view to a subnet e.g. 192.168.99.0 / 24. It seemed to only offer Class A, B or C groups. My whole network is a subneted class B so not very useful.

Similar problem with the IP Address Group Resource.

Thanks again

Andrew
