Chris , Thanks for the info... Let me explain my requirement .... My company has 3 upstream providers and we are serving more than 400 customers ..In that case we have to manage our upstream capacity... When considering capacity managing normally we just transfer a /24 from congested Up stream provider to non congested provider. Issue we have is we don't know exactly the usage of a /24 subnet before transfer.
I hope you get an idea about my requirement :) :) :) On Wed, Feb 18, 2015 at 8:40 AM, Methsri Wickramarathna < mmethw2...@gmail.com> wrote: > Karsten , thanks for replying.... > It's like this I don't want to take router info, only thing i want is to > graph the usage of my entire IP block per subnet wise. > Normaly we are using CACTI , MRTG , Observium etc... to gather router > information such as CPU , errors , usage etc... > > All the systems mentioned above use SNMP to gather info and when it comes > to usage it only poll to a particular interface and plot the usage ......I > hope you had an idea about my requirement :) > > > On Tue, Feb 17, 2015 at 11:53 PM, Karsten Thomann < > karsten_thom...@linfre.de> wrote: > >> 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.
