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
