Without the use of 3rd party applications, how can I perform monitoring on a router? For example, how can I monitor a specific workstation with it's I.P address or hostname with information on what type of traffic it's traversing inbound and outbound to and from the internet? For eg, I would like to monitor data transmissions, the source of the transmission (ie youtube video downloading, ebay browsing), etc etc
In addition to net flow you can also think off using NBAR (which is memory extensive) to export the details like your traffic with both in/out bytes/packets to an external system so that you can verify the amount of data transmission with respect to each port or application.
I want to enable the logging on a cisco 2500 that I have here. This router, routes traffic from the LAN through a T1 to another network. I'm trying to establish the netflow on this router, but it doesn't accept the command. I tried to establish it on any of the interfaces but none of them seem to work. It has different switches in replacement to "flow" as stated in my previous comment.
