RE: Limit Internet BW [7:34201]
What type of connection is between site A and B ? Without knowing you layout, it might be possible to use queuing to limit what address's get a percentage of the bandwidth. If you can't do it internal, and assuming you can assign each site a different external IP address, you could just filter on the external router. Not elegant, and not overly efficient, but a work around. I would look at CBWFQ with 2 separate classes with the 1280 statement under the main or unlimited class. Not elegant but a way to closely accomplish what your looking for. I suppose that you could also use custom queuing and set the byte count as well.not a fan of that though. Keep in mind that queuing is usually meant to assure a minimum amount of bandwidth, not a maximum so you have to look at this from the perspective of give the max I can to Site B, while letting the rest ( 256 K ) be free for site A. Is it critical that site A NEVER gets more that 256 regardless of the other sites needs ? If so then the above is mute, because queuing will only come into play during periods of congestion. When its idle, they can use all that they want.

RE: Limit Internet BW [7:34201]
Hello Larry, My problem is that the sites are at close Proximity. (inside a building) And using ethernet Switch for the connections as the Internet link get terminated to the same switch. But using different subnets for two sites with Vlans on the Switch. I want Site B to keep from bursting the link and to allow more important traffic from site A to get through. Thanks for the idea.

Fernando, To limit traffic there is basically two places : Ingress and Egress (but usually on ingress) : Rate limit using "Commited Access Rate - CAR" Egress only : Shaping with "GTS" Frank s.

access-list 1 permit ip.of.sit.e1 (these are the sites you are rate-limiting.) access-list 1 permit ip.of.sit.e2 (these are the sites you are rate-limiting.) interface serial x/x (the interface closest to the site you want to rate limit) rate-limit input access-group 1 XXX YYY ZZZ conform-action transmit exceed-action drop rate-limit output access-group 1 XXX YYY ZZZ conform-action transmit exceed-action drop XXX - Normal speed in bps (multpiples of 8) YYY - Normal Burst speed. (supposedly the minimum is XXX/2000, but I can't test it right now.) ZZZ - Max Burst speed.

Re: Limit Internet BW [7:34201]
What you are running on T1? If you are running Frame Relay, use FRTS to configure the CIR. Another way is to use rate-limit command on the interface. Another way is to use class based queuing to allocate the bandwithd to different class of services.
