RE: Trafic Shaping [7:51661]
QoS Device Manager (QDM) is a great tool (small java applet) for this. http://www.cisco.com/univercd/cc/td/doc/product/rtrmgmt/qdm/ http://www.cisco.com/warp/public/cc/pd/nemnsw/qodvmn/prodlit/qdm_ds.htm Requires 12.1(5)T or later on your 2600, as it uses CEF & NBAR.

RE: Trafic Shaping [7:51661]
you can block kazaa, etc with a simple access list.. all those fast track network front end clients (kazaa, grokster, etc) work on tcp/1214 so for me it would be access-list 101 deny tcp any any eq 1214 access-list 101 permit ip any any keep adding access-list 101 deny * * eq as you find new programs or services the students run to. I would also put the students in a different ip range (private, public whatever) than the staff, and deploy traffic shaping.. then i would limit the students to a fair amount of bandwidth maximum per second, say 786Kbps, or you can use car which will make sure the teachers' ip block always get through. research QOS on cisco's site for this.

RE: Trafic Shaping [7:51661]
I would suggest a rate-limiting device like that available from Packeteer. It allows you to rate-limit certain classes of traffic without changing your router configuration. It might work really well for this situation. You might also try CAR on the incoming interfaces. This is made more difficult because you don't have a good way to influence which T1 incoming traffic arrives on. Sure, you can load-balance outgoing requests for content but those don't use up much bandwidth. It's the incoming traffic that gets you and that's the hardest to influence. If you're running BGP, you can advertise the student network addresses out one interface while advertising the admin staff addresses out the other. If you then advertise the aggregate out both links you'll have a failover should problems arise. This isn't perfect but it might help. You might end up needing to take several different smaller steps in order to alleviate the problem.

The first thing we are trying to to is to route the traffic through different interface. Well the root of problems is the mp3 down load from Kazzar napster etc . any suggestion -Original Message- From: John Neiberger [mailto:[EMAIL PROTECTED]] Sent: Monday, August 19, 2002 4:10 PM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: Trafic Shaping [7:51661] Policy-based routing would allow you to accomplish this goal.
