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.

Thanks Armin , I will try the SW you have mentioned seems like it's not easy to install though :) :)
Karsten, I just bought out an example... my company has 2X18's and out of it we are using considerable amount of /24s to access internet . Some subnets are given without proper documentation , so it's very hard to do what you have proposed. What I can do is to install some kind of SW and gather info from my gateway routers :( .....it's helpful if some one can guide me through this :) ...

Hi,
I'm not sure how it is exactly build, but if every /29 uses it's own port a tool like cacti/graphite where you're aggregating all required ports within one graph is easier.

Hi All, I have a requirement to plot a usage graph per subnet. As an example.
I have a 192.168.1.0/24 subnet divided among 32 customers where each one will get a /29 [ 192.168.1.0/29 => Customer A ; 192.168.1.8/29 => Customer B etc... ] ...
Is there any tool to graph the usage of entire /24 subnet ???
