We have been experiencing very slow internet connection problem such that our users find it very difficult to browse legitimate sites and the systems can't download needed updates.
I contacted our Internet service provider and they insisted that the problem is from our end, they said that there is a lot of upload from our network, that probably it may be due to virus activities.
Please how can I monitor flow from individual end systems to determine the ones that are using much bandwidth?
I used the 'ip route-cache flow' in interface configuration mode of my internet router.
But I don't know how to interpret the 'show ip cache flow' or 'show ip cache' outputs or how to export the flow statistics real time to windows where i can monitor it.
Can some one help me with suggestion on how I can monitor the system bandwith usage or how to interpret and use the 'show ip cache flow' output.
