traffic monitoring

[clearwaterms]

Okay, this should be simple...

I have a t1 connection, point to point between to offices. I have a Cisco 2800 on one side and a 3640 on the other. I need to find a way to monitor the traffic that is going across the link, All I am looking for is who sent the packet, where was it destined, and the port it was sent on...

Somebody please help I am hoping to find something that will do it in a logging format, however if it would export to CSV that I can use Excel would work as well

Have you looked at Ethereal? Its free, and will do exactly what you want. It even comes with capture and display filters to weed out anything you don't want to see.

I have never heard of Ethereal, however this is a isolated T1 with only two endpoints, there are no other devices that exist on it. Only a Cisco on either side.
