T1 simulator and bandwidth restrictor

I currently house a database and Web server at my site for one of my clients. My client is considering moving the database to their location while leaving the Web Server at my site. Is there any way for me to simulate a T1 either between two of my routers or over my 100MB LAN in an effort to restrict bandwidth to the two servers. I guess it would be sort of like QOS in reverse whereby I am wanting to set a maximum bandwith to guarantee.

Re: T1 simulator and bandwidth restrictor

You can use CAR on your FE interface to throttle this down.

The newer way to do this is using a policer "policy-map" with a rate limiter.

This will do your BW allocation down to what rate you would like but if you are looking for a good test, the above does not account for serialization delay, PPP or HDLC framing issues, etc, you might go with Back to back serials between routers. In this way you can go much slower with your speeds using "clockrate" and better symulate end to end latency as well as BW issues.

Hope this helps,

Don
