How to get network traffic in/out volume by port?

We have a 2620 router on a T1 line. I'm looking for a way to get periodic counts of inbound/outbound traffic by TCP port #, to help identify source of periodic high bandwidth utilization. I heard there's a way to do this in our Cisco router? I'd appreciate any pointers to tips or documentation on this.

TIA

Hi,

You can do this by enabling netflow on the interface

Have a look here for more info
