asked on How to find the IP address which consumes the network bandwidth in real time ?
People,
I'm just a server support engineer so I have no clue in networking, so I need you help to assist me in what software or technology to find which IP address in my network is consuming the largest bandwidth ?
I have extended the network bandwidth for Guest wireless from 10 MBps to 20 MBps but it is still maxed out.
Note: all of the network switch and WLAN AP are Cisco brand, the Firewall is Juniper brand.
If possible the solution is the freeware ones or not more than $250 in terms of software license.
Thanks

Jupiter should have some sort of utility in it's firewall that let's you see who the top ip talkers are ,and where they are connecting too.
PRTG will tell you the traffic levels. Is that good enough? By switch port so you can narrow down the device.

Hi All,
This is the problem that occuring intermittently. I've got some Marketing Contractor who uses the Guest Wifi internet which I suspect is downloading and uploading too much of a data.
Netflow has been enabled on the 4x Cisco switch Catalyst 3850 (Core switch at the data center and the HQ office) and then the log is captured in the monitoring server, parsed by PRTG.
But I find it is quite hard to understand the top IP talker with PRTG.
Is there any better alternative that does not cost additional software license to buy perhaps ?

AVC, like I said. It's built-in to the WLC.

Craig,
Doyou mean enabling the Cisco Application Visibility and Control (AVC) feature on all the Cisco WLAN ?

Fred Marshall,
yeah that's the thing, the Wifi AP is of course conencted to one of the HQ-Core Switch but the problem is which IP address consuming is another problem to resolve.

OK, upon investigating on the site and looking at the detail of the AP, it is using Cisco Virtual WLC and 9x Cisco Aironet AIR-AP1262N-N-K9 Access Points.
Does it have Cisco Application Visibility and Control (AVC) feature ?

I have enabled that technology and then use PRTG in the past but don't know how to interpret ?
