Can anyone recommend a bandwidth monitoring tool that would allow us to display on a screen realtime bandwith stats dynamically updating between our core and access layer switches? Basically we want to setup a screen that will constantly display dynamically updating real time bandwidth traffic numbers between all our access layer switches at different sites and our core. Our switching and routing infrastructure is all Cisco. Can anyone recommend a product that is not very expensive that could accomplish this? Ideally we'd like to display not just one link at a time but all of them simultaneously too.
