I need help configuring QoS on a Cisco 2821 router. Our Internet connection is an ADSL (6Mb/s DOWN / 768Kb/s UP). There are about 50+ users competing for the bandwidth and we've had many occurances of people downloading large files and causing critical applications to fail.
I've set up QoS on the router (see configuration below), which has help but we still have "run away" applications that cause the ADSL to be completely saturated.
